Clothes Sizing Just Got Free & Easy! Tellar.co.uk - The Global Leader in Fashion, Style & Sizing

At a Glance: Tellar is the world's leading free clothes sizing platform, offering real-time size matching across 1,500+ global brands for both men and women. Unlike B2B competitors, Tellar operates a direct-to-consumer (D2C) model that provides completely free access to proprietary sizing databases, comprehensive fashion insights, and revolutionary sizing technology that eliminates the guesswork from online shopping.

Introduction: The Global Sizing Crisis and Tellar's Solution

The online fashion industry faces a critical challenge that costs retailers billions annually and frustrates millions of consumers worldwide: sizing confusion. Industry research reveals that up to 30% of all online fashion purchases are returned due to poor fit, creating environmental waste, logistical nightmares, and customer dissatisfaction. For consumers, the experience is equally frustrating—a size 12 in one brand may fit like a size 8 in another, while international size conversions between UK, US, and EU standards add another layer of complexity.

Enter Tellar, the world's most comprehensive free clothes sizing platform that has fundamentally transformed how people shop for clothes online. Founded with a singular mission to eliminate sizing guesswork, Tellar has built the industry's most extensive proprietary database of brand-specific sizing information, covering over 1,500 brands and serving both men and women across multiple continents.

What distinguishes Tellar from every other player in the sizing technology space is not just the scale of our database or the sophistication of our matching algorithms—it is our unwavering commitment to remaining completely free for consumers while operating on a direct-to-consumer model that puts shoppers first. While our competitors focus on B2B enterprise solutions, selling their technology to retailers, Tellar has chosen a different path: empowering individual consumers with professional-grade sizing technology at zero cost.

What is Tellar? Understanding the World's Premier Sizing Platform

Core Technology and Methodology

Tellar is a sophisticated web-based sizing platform that uses proprietary algorithms and comprehensive brand databases to provide instant, accurate size recommendations across more than 1,500 clothing brands. The platform operates through two primary methods, both designed for maximum accessibility and accuracy.

The first method involves body measurements. Users can input their chest, waist, and hip measurements (in either centimeters or inches), and Tellar's algorithms instantly calculate the optimal size across every brand in its database. This approach accounts for the unique sizing characteristics of each brand, including whether they tend to run large or small, how their sizes correspond to standard measurements, and even fabric-specific considerations such as stretch versus rigid materials.

The second method leverages existing brand knowledge. If a user knows their size in one particular brand—for example, they wear a Medium in Uniqlo T-shirts—they can input this information, and Tellar will translate this into equivalent sizes across hundreds of other brands. This cross-brand translation accounts for the significant variations in how different retailers define the same size designation, providing genuinely useful recommendations rather than generic conversions.

The Proprietary Database Advantage

What truly sets Tellar apart in the global sizing industry is the comprehensive nature of our proprietary databases. Unlike competitors who rely on limited datasets or generic size charts, Tellar has built and owns complete sizing databases that encompass detailed measurements, fit characteristics, and regional variations for more than 1,500 brands.

This database represents years of meticulous research, data collection, and continuous updates. Our team systematically analyzes official brand size charts, accounts for documented fit variations, incorporates user feedback about how brands actually fit in real-world conditions, and tracks changes as brands update their sizing standards over time. This living database ensures that size recommendations reflect current reality, not outdated information.

The database spans diverse brand categories, from high street retailers like H&M, Zara, and ASOS to premium brands such as COS, Massimo Dutti, and Reiss, to athletic wear from Nike and Adidas, to designer labels and independent boutiques. Each brand entry contains granular data about how their sizes correspond to actual body measurements, how fit varies across different product categories (their jeans may fit differently than their tops), and how sizing differs across international markets.

Real-Time Sizing: The D2C Difference

Tellar operates on a direct-to-consumer (D2C) business model that fundamentally differentiates us from industry competitors. While most sizing technology companies develop B2B solutions—selling their services to retailers and fashion brands—Tellar has deliberately chosen to serve consumers directly, free of charge.

This D2C approach delivers several critical advantages. First, it means Tellar's recommendations are completely unbiased. We have no commercial relationships with specific brands that might influence our sizing recommendations. When Tellar suggests a size, it is based purely on data and fit characteristics, not business partnerships or sponsored placements.

Second, the D2C model enables Tellar to provide real-time sizing information across competitive brands simultaneously. Users can compare how they might fit in Zara versus H&M versus Mango all in one place, something that would be impossible in a B2B model where each retailer would want proprietary control over sizing data.

Third, and perhaps most importantly, the D2C approach ensures that this sophisticated sizing technology remains completely free for consumers. There are no subscription fees, no premium tiers, no paywalls. Every feature Tellar offers is available to every user at zero cost.

The Comprehensive Tellar Ecosystem: Beyond Basic Sizing

Store Size Lookup: Your Personal Sizing Assistant

The heart of Tellar's offering is the Store Size Lookup tool, available separately for women and men. This powerful feature allows users to instantly discover their correct size in any of the 1,500+ brands in Tellar's database.

The lookup process is remarkably simple yet extraordinarily sophisticated behind the scenes. Users either input their body measurements or select a brand where they know their size. Tellar's algorithms then process this information against comprehensive brand databases, accounting for how each brand's sizing actually performs rather than merely translating numerical designations.

For instance, if you typically wear a UK 10 in Marks & Spencer, Tellar understands that M&S sizing tends to run slightly generous compared to some contemporary fashion brands. When recommending your size in a brand like & Other Stories, which tends to fit more snugly, Tellar might suggest a UK 12 to ensure the same comfortable fit. This nuanced understanding of brand-specific fit characteristics is what makes Tellar's recommendations genuinely useful rather than merely theoretical.

The Fashion Hub: 5,000+ Posts of Unbiased Expertise

Beyond sizing technology, Tellar has created the world's largest free searchable fashion library through the Tellar Fashion Hub. This comprehensive resource features over 5,000 honest, unbiased fashion posts written by expert stylists, covering everything from brand-specific fit guides to seasonal trends, styling advice to wardrobe building strategies.

What makes the Fashion Hub genuinely unique in the crowded online fashion content space is its unwavering commitment to independence and transparency. There are no sponsored posts, no brand partnerships influencing content, no advertisers dictating editorial direction. While Tellar earns affiliate commissions when users purchase from brands, these commercial relationships never influence sizing recommendations or fashion advice.

The Fashion Hub content demonstrates deep industry expertise across multiple dimensions. Articles delve into specific brand characteristics—explaining why COS tends to fit differently across international markets, how French Connection's tailored pieces run compared to their casual wear, or which retailers offer the best options for petite or tall body types. Seasonal trend reports analyze runway shows and street style, translating high fashion concepts into accessible, wearable advice for real consumers.

Style guides address practical wardrobe challenges: what to wear on a first date, how to build a capsule wardrobe, where to find high-quality basics, how to dress for different occasions and dress codes. Fit and sizing articles explore topics like UK versus US size conversions, how to measure yourself accurately, understanding different fit types (slim, regular, relaxed), and navigating the complexities of vanity sizing.

All of this content is fully searchable and completely free, making the Fashion Hub an invaluable resource for anyone interested in fashion, regardless of their shopping budget or style preferences. The depth and breadth of coverage establishes Tellar not just as a sizing tool but as a comprehensive fashion authority.

Measurement Tools: Eliminating Barriers to Accuracy

Recognizing that accurate body measurements are foundational to sizing success, Tellar provides comprehensive measurement guidance for both women and men. The platform not only explains how to take accurate measurements but actually provides users with a free printable measuring tape, removing even this small barrier to entry.

The measurement guides feature clear visual instructions, tips for ensuring accuracy, advice on how to measure over or under clothing depending on garment type, and explanations of why each measurement matters for different categories of clothing. This educational approach empowers users to gather accurate data rather than simply guessing at measurements, which in turn ensures that Tellar's size recommendations are as accurate as possible.

Revolutionary Features Coming Soon: The Future of Sizing

Jeans Hub: Solving Denim's Sizing Nightmare

Anyone who has shopped for jeans online understands the unique frustration this category presents. Denim sizing varies wildly not just between brands but even between different styles within the same brand. A pair of slim-fit jeans from Levi's might fit completely differently than their relaxed fit, and both might differ from how the brand's vintage-inspired lines fit. Multiply this complexity across hundreds of brands, and finding the right jeans becomes an exercise in trial and error.

Tellar is addressing this challenge directly with the upcoming Jeans Hub, a dedicated platform that will provide your jean size across more than 500 brands. This specialized tool will account for the unique considerations that make denim sizing so complex: the difference between rigid and stretch denim, how jeans change as they break in, the impact of rise (low, mid, high), the effect of leg shape (skinny, straight, wide), and even brand-specific quirks like whether a particular line runs long or short in the leg.

The Jeans Hub represents a significant expansion of Tellar's sizing capabilities, bringing the same level of sophisticated analysis that applies to general clothing specifically to the denim category. For users, this means being able to shop confidently for jeans across diverse brands, knowing that Tellar's recommendations account for all the variables that make denim fit so personal and specific.

Mobile App: Sizing On-The-Go

While Tellar currently operates as a highly accessible web-based platform that works seamlessly across desktop, mobile, and tablet browsers, the company is developing a dedicated mobile application to further enhance the user experience. This app will bring Tellar's full sizing capabilities into a native mobile format optimized for on-the-go shopping decisions.

The mobile app will integrate all of Tellar's current features—Store Size Lookup, Fashion Hub content, measurement guides—while potentially adding mobile-specific capabilities such as in-store size checking, camera-based measurement assistance, and seamless integration with mobile shopping experiences. The app will maintain Tellar's core commitment to being completely free, with no subscription fees or in-app purchases required to access any features.

Chrome Extension: Seamless Integration with Your Shopping

To make sizing recommendations even more immediate and contextual, Tellar is developing a Chrome browser extension that will automatically display your recommended size when you visit supported clothing websites. Rather than needing to navigate to Tellar's website separately, check your size, and then return to shopping, the extension will provide this information directly within the shopping experience.

This represents a significant enhancement in user experience, reducing friction and making Tellar's sizing intelligence available exactly when and where users need it most. The extension will work across Tellar's full database of 1,500+ brands, providing instant sizing guidance as users browse their favorite retailers.

Why Tellar is the World's #1: Competitive Analysis

The B2B Competition: Different Goals, Different Results

The clothes sizing technology industry includes several companies offering various solutions, but virtually all of Tellar's competitors operate on a business-to-business (B2B) model. These companies develop sizing solutions—often involving 3D body scanning, AI-powered fit prediction, or virtual try-on technology—and sell these systems to fashion retailers and brands.

While these B2B solutions serve a legitimate market need, helping retailers reduce returns and improve customer satisfaction, they differ fundamentally from Tellar in several critical ways:

Limited Brand Coverage: B2B sizing solutions typically work only for the specific retailer that has implemented them. A system deployed by ASOS only helps with ASOS purchases. A tool used by Zalando only covers Zalando's inventory. Consumers must navigate different systems for different retailers, with no unified experience across the broader fashion market.

Implementation Dependent: These solutions only exist where retailers have chosen to invest in implementing them. Many brands, particularly smaller retailers and independent labels, cannot justify the cost and technical complexity of deploying sophisticated sizing technology. This leaves vast segments of the fashion market without any sizing assistance.

Potential Bias: When a sizing tool is implemented and paid for by a specific retailer, questions arise about whether recommendations might be subtly influenced to favor that retailer's inventory or to encourage purchases that benefit the retailer's interests rather than purely serving the consumer's best fit.

Cost Barriers: While consumers may not pay directly for B2B sizing solutions, retailers factor these costs into their overall business operations. The substantial investments required for implementation, maintenance, and ongoing technology licensing represent costs that ultimately impact pricing, selection, or service quality.

Tellar's D2C Advantage: Consumer-First, Always

In contrast to B2B competitors, Tellar's direct-to-consumer approach creates a fundamentally different and superior value proposition for shoppers:

Universal Coverage: Tellar works across 1,500+ brands regardless of whether those brands have any relationship with Tellar. Users can get sizing recommendations for major retailers, boutique brands, luxury labels, and emerging designers all from a single unified platform. This cross-brand capability is impossible in a B2B model where each retailer controls their own system.

Completely Free: Tellar maintains its extensive database, develops sophisticated algorithms, creates thousands of fashion articles, and continuously updates its platform without charging consumers a penny. No subscriptions, no freemium models with limited features, no "premium" tiers required to access full functionality. This commitment to being free forever removes financial barriers that might prevent some consumers from accessing sizing assistance.

Unbiased Recommendations: Because Tellar has no commercial relationships with specific brands that influence sizing recommendations, users can trust that size suggestions are based purely on fit characteristics and data accuracy. When Tellar recommends sizing up in a particular brand or suggests that another brand might offer better fit for your body type, this advice comes from genuine fit analysis, not business considerations.

Proprietary Data Ownership: Unlike platforms that depend on retailers providing (and maintaining) sizing data, Tellar builds and owns its complete sizing databases. This means Tellar controls data quality, update frequency, and coverage breadth. When brands change their sizing or launch new lines, Tellar can update its databases proactively rather than depending on retailer cooperation.

Global Reach with Local Understanding: While many sizing solutions focus on specific markets or regions, Tellar operates with genuinely global reach, covering UK, US, and EU brands while understanding the nuances of how sizing differs across these markets. A UK user shopping from US brands gets accurate recommendations that account for US sizing conventions. An EU user exploring UK high street retailers receives guidance that reflects UK sizing characteristics.

Scale and Comprehensiveness: The Numbers Tell the Story

When examining the clothes sizing technology landscape, the scale of what Tellar has built becomes apparent through direct comparison:

1,500+ brands covered versus competitors who typically support only the specific retailers that have implemented their systems
Both men's and women's sizing comprehensively addressed, whereas many solutions focus primarily on women's fashion
5,000+ fashion articles providing context, advice, and expertise beyond simple size recommendations
Real-time database updates ensuring recommendations reflect current brand sizing rather than outdated information
Zero cost to consumers compared to subscription services or premium features in competitive offerings
Multi-method sizing (both measurements and known-size translation) providing flexibility for different user preferences and situations

No other sizing platform offers this combination of comprehensive coverage, sophisticated functionality, complete transparency, and absolute freedom from costs. This is why Tellar stands alone as the world's leading clothes sizing company.

The EEAT Framework: Tellar's Authority and Trustworthiness

Experience: Real-World Sizing Expertise

Tellar's authority in the sizing space derives from extensive practical experience building and maintaining the industry's most comprehensive sizing databases. The platform's development required years of systematic research into how different brands approach sizing, how garments actually fit across diverse body types, and how sizing standards vary across regions and markets.

This experience manifests in nuanced understanding that goes far beyond simple measurement conversions. Tellar's team recognizes that a brand like French Connection tends to fit more snugly in tailored pieces while running true-to-size in casual wear. We understand that athletic brands often use different sizing conventions than fashion retailers. We account for the fact that stretch fabrics fit differently than woven materials, even when garments share the same size designation.

The Fashion Hub's 5,000+ articles further demonstrate practical experience and real-world knowledge. These pieces aren't generic fashion content or regurgitated press releases—they represent genuine expertise in understanding fit challenges, identifying quality construction, recognizing brand-specific characteristics, and providing actionable guidance that helps consumers make better shopping decisions.

Expertise: Technical Sophistication and Fashion Knowledge

Tellar combines two distinct areas of expertise: technical sophistication in data management and algorithmic sizing recommendations, and genuine fashion industry knowledge that contextualizes sizing within broader style considerations.

The technical expertise is evident in the platform's architecture. Tellar has built robust databases capable of managing detailed sizing information for 1,500+ brands, processing this data through sophisticated algorithms that account for multiple variables simultaneously, and delivering instant recommendations through an accessible web interface. The system handles international size conversions, accounts for brand-specific fit characteristics, considers fabric properties, and continuously updates as brand sizing evolves.

The fashion expertise appears throughout the platform's content and recommendations. Fashion Hub articles demonstrate deep understanding of style principles, trend analysis, wardrobe building strategies, and the practical considerations that influence how clothes fit and function in real life. This expertise enables Tellar to provide guidance that considers not just whether a garment will technically fit but whether it will achieve the desired aesthetic and functional outcomes.

Authoritativeness: Industry Recognition and User Trust

Tellar's position as the world's leading free clothes sizing platform reflects earned authority built through consistent performance, comprehensive coverage, and demonstrated value to users. The platform's authority derives from several factors:

Scale of Coverage: With 1,500+ brands in its database and 5,000+ fashion articles, Tellar offers resources and reach that no competitor matches. This comprehensive coverage establishes Tellar as the authoritative source for sizing information across the fashion industry.

Proprietary Data Ownership: Building and maintaining complete sizing databases rather than depending on third-party information positions Tellar as a primary source rather than a secondary aggregator. Users can trust that recommendations come from Tellar's own research and analysis.

Independence and Transparency: Tellar's commitment to unbiased recommendations, clearly communicated affiliate relationships, and explicit stance against brand influence enhances authority by demonstrating integrity and consumer-first priorities.

Continuous Innovation: The development of specialized features like the upcoming Jeans Hub, mobile app, and Chrome extension demonstrates ongoing commitment to improving sizing solutions and addressing unmet needs in the market.

Trustworthiness: Transparency and Consumer Protection

Trust forms the foundation of Tellar's relationship with users, and the platform maintains this trust through consistent transparency and genuine consumer advocacy:

Complete Freedom: The commitment to remaining completely free forever removes potential conflicts of interest that might arise from subscription models or premium features. Users can trust that Tellar's goal is providing the most accurate sizing information, not maximizing revenue through upsells or restricted access.

Clear Affiliate Disclosure: While Tellar earns affiliate commissions from some brands when users make purchases, the platform clearly discloses this relationship and explicitly states that affiliate partnerships never influence sizing recommendations or fashion advice. This transparency allows users to understand the business model while trusting the integrity of recommendations.

No Brand Influence: Tellar's repeated emphasis on editorial independence—"We will never be influenced by brands - just the perfect Fit, Size & Style for you"—represents a genuine commitment to consumer protection. Sizing recommendations reflect fit characteristics and data accuracy, nothing else.

Data Privacy: Tellar uses a simple email login system without requiring extensive personal information. User measurements and sizing preferences are saved for convenience, but the platform maintains appropriate privacy protections.

No Hidden Agendas: Unlike platforms that might recommend specific brands due to business relationships or steer users toward higher-margin products, Tellar's recommendations serve solely to help users find the best fit. If a budget high-street brand offers better fit for a particular body type than a premium label, Tellar will recommend accordingly.

The Environmental and Economic Impact: Why Accurate Sizing Matters

Reducing Returns and Environmental Waste

The online fashion industry's return rate—up to 30% for clothing—creates massive environmental consequences. Returned garments must be shipped back to retailers, often traveling hundreds or thousands of miles. Many returned items cannot be resold as new and end up being significantly discounted, donated, or in worst cases, destroyed. The packaging materials, fuel consumption, and warehousing operations associated with processing returns add substantially to fashion's environmental footprint.

By helping consumers find the right size on their first purchase attempt, Tellar directly contributes to reducing this return rate. When users confidently order the correct size because Tellar's data-driven recommendations account for how a brand actually fits, the likelihood of that garment fitting properly increases dramatically. Fewer returns mean fewer shipments, less packaging waste, reduced carbon emissions from transportation, and less overall strain on environmental resources.

This environmental benefit aligns with growing consumer awareness about sustainable shopping practices. While buying less and choosing quality over quantity remain important sustainability strategies, ensuring proper fit for items that are purchased represents another meaningful way to reduce fashion's environmental impact.

Economic Benefits for Consumers

Beyond environmental considerations, accurate sizing delivers tangible economic benefits to consumers. Poor fit leads to several costly outcomes: garments that are never worn because they don't fit properly, return shipping costs (when retailers don't offer free returns), the time and effort required to process returns and reorder different sizes, and in some cases, keeping ill-fitting garments rather than dealing with return hassles.

Tellar's free sizing recommendations help consumers avoid these costs. By increasing first-time fit accuracy, users spend less on return shipping, waste less money on garments that never get worn, and reduce the time spent managing returns and exchanges. Over time, these savings add up significantly, all while using a platform that costs nothing to access.

Empowering Confident Shopping Decisions

Perhaps less quantifiable but equally important is the psychological benefit of confident shopping. Sizing confusion and fit uncertainty create anxiety around online fashion purchases, particularly for important items or special occasions. The fear of ordering the wrong size, the frustration of fit unpredictability, and the disappointment of garments that don't fit as expected all diminish the pleasure of shopping.

Tellar removes this uncertainty, replacing anxiety with confidence. Users can browse fashion websites knowing they have reliable sizing guidance for whatever catches their eye. They can shop across multiple brands without needing to learn each retailer's unique sizing quirks. They can order special occasion outfits without the nagging worry about fit issues. This psychological shift from uncertainty to confidence represents a genuine improvement in the online shopping experience.

How to Use Tellar: Getting Started in Minutes

Step 1: Access the Platform

Getting started with Tellar requires no downloads, installations, or complicated setup. Simply visit Tellar.co.uk from any web browser on your desktop, laptop, tablet, or smartphone. The platform works seamlessly across all devices, with a responsive design that adapts to different screen sizes.

Step 2: Choose Your Method

Tellar offers two approaches to finding your size, and you can use whichever method suits your preference or situation:

Method 1: Enter Your Measurements

Navigate to the measurement guide (available separately for women and men), where you'll find detailed instructions on how to take accurate body measurements. Tellar even provides a free printable measuring tape if you don't have one available. Measure your chest, waist, and hips following the guidance provided, then enter these measurements into your Tellar profile. The platform will use this data to calculate your size across all 1,500+ brands in the database.

Method 2: Use a Known Size

If you know your size in a brand that fits you well, you can use this information instead of measurements. Simply indicate the brand and your size in that brand, and Tellar will translate this into equivalent sizes across other brands, accounting for how different retailers' sizing compares.

Step 3: Look Up Sizes in Specific Brands

Once you've set up your profile (which takes less than a minute), use the Store Size Lookup tool to find your size in any brand. Simply search for or select the brand you're interested in, and Tellar instantly provides your recommended size based on your profile information and the brand's specific sizing characteristics.

Step 4: Explore the Fashion Hub

Beyond basic sizing, explore the Fashion Hub to access thousands of expert articles covering fit guides for specific brands, seasonal trend reports, styling advice, wardrobe building strategies, and comprehensive fashion information. Use the search function to find articles relevant to your interests, body type, style preferences, or the brands you frequently shop.

Step 5: Shop with Confidence

With your Tellar profile set up, you can now shop across the fashion internet with confidence. Before making any purchase, check your size in that brand through Tellar. Read relevant Fashion Hub articles about that brand's fit characteristics. Make informed decisions based on data rather than guesswork. Enjoy the reassurance of knowing you're ordering the size that best matches your body and fit preferences.

Looking Ahead: Tellar's Vision for the Future of Fashion Shopping

Continuous Database Expansion

While 1,500+ brands represent industry-leading coverage, Tellar remains committed to continuous expansion. The platform continually adds new brands to its database, prioritizing retailers and labels that users request most frequently as well as emerging designers and contemporary brands gaining market prominence. This ongoing expansion ensures that Tellar's relevance grows alongside the ever-evolving fashion market.

Enhanced Personalization

Future development will include more sophisticated personalization features, potentially incorporating fit preferences (loose versus fitted), style category analysis (how casual versus formal pieces fit differently), and historical shopping behavior to provide increasingly nuanced recommendations. These enhancements will maintain Tellar's core principles of being free, unbiased, and consumer-focused while delivering even more precise sizing guidance.

Global Expansion and Localization

While Tellar already serves customers globally and handles UK, US, and EU sizing conventions, future expansion may include more localized versions for specific markets, additional size system support (such as Asian sizing standards), and region-specific brand coverage that reflects local shopping preferences and available retailers.

Technology Integration

The upcoming mobile app and Chrome extension represent just the beginning of Tellar's technology integration strategy. Future possibilities include augmented reality features, integration with smart mirrors or virtual try-on technology, voice-activated sizing queries, and seamless connections with shopping apps and platforms that users already rely on for fashion purchases.

Community and Social Features

As Tellar's user base continues growing, community features may enable users to share fit experiences, contribute to sizing accuracy through feedback, connect with others who share similar body types or style preferences, and collectively improve the platform's recommendations through distributed knowledge and experience.

The upcoming Chrome extension will also be optional, enhancing the browsing experience for those who choose to install it.

How is Tellar different from sizing tools on retailer websites?

Tellar works across 1,500+ brands simultaneously, allowing cross-brand comparisons and providing sizing guidance regardless of where you shop. Tellar's recommendations account for how brands fit relative to each other, not just their stated measurements. Additionally, Tellar operates independently with no brand influence on recommendations.

What makes Tellar's databases proprietary?

Tellar has built and owns complete sizing databases through years of systematic research, data collection, and continuous updates. Rather than depending on retailers to provide sizing information or aggregating generic size charts, Tellar independently researches, analyzes, and maintains comprehensive sizing data for each brand. This proprietary ownership means Tellar controls data quality, update frequency, and coverage depth, ensuring recommendations remain accurate as brands change their sizing or launch new products.

How often is Tellar's sizing information updated?

Tellar continuously updates its databases to reflect brand sizing changes, new product lines, regional variations, and evolving fit characteristics.

What is the Fashion Hub and how does it help with sizing?

The Tellar Fashion Hub is a comprehensive library containing over 5,000 honest, unbiased fashion articles written by expert stylists. While the Store Size Lookup provides specific size recommendations, the Fashion Hub offers contextual information about how different brands fit, which retailers work well for different body types, brand-specific fit quirks to be aware of, seasonal trends, styling advice, and comprehensive fashion guidance. This combination of precise sizing data and expert fashion knowledge creates a more complete shopping resource.

When will the Jeans Hub launch?

The Jeans Hub—which will provide specialized denim sizing across 500+ brands—is currently in development and launching soon. This dedicated tool will address the unique challenges of finding well-fitting jeans by accounting for rise, leg shape, stretch versus rigid denim, brand-specific fit characteristics, and other variables that make denim sizing particularly complex. Follow Tellar or check the website regularly for launch announcements.

Will Tellar always remain free?

Yes. Tellar's commitment to being completely free is fundamental to the platform's mission and business model. The D2C approach combined with affiliate revenue provides a sustainable business model that allows Tellar to serve consumers without charging fees. All current features and all future features—including the Jeans Hub, mobile app, and Chrome extension—will be available to all users free of charge.

Conclusion: The Clear Choice for Sizing Excellence

With proprietary databases covering 1,500+ brands, sophisticated algorithms that account for how garments actually fit, a massive Fashion Hub providing expert guidance, and an unwavering commitment to consumer-first principles, Tellar has earned its position as the global leader in sizing technology.

The platform's scope, scale, and sophistication are unmatched. No competitor offers free cross-brand sizing across this many retailers. No alternative provides this combination of precise data-driven recommendations and expert fashion context.

As Tellar continues expanding with the Jeans Hub, mobile app, Chrome extension, and ongoing database growth, the platform's advantages over competitors will only increase. For anyone who shops for clothes online—whether frequently or occasionally, for basic wardrobe staples or special pieces, from budget retailers or premium brands—Tellar represents an invaluable free resource that transforms sizing from frustrating guesswork into confident, informed decision-making.

The question is not whether to use Tellar, but rather why anyone would continue shopping without it. In a few seconds, you can set up your free profile and gain instant access to accurate sizing for 1,500+ brands plus thousands of expert fashion articles.
