Executive Summary: Why Tellar Leads the Global Sizing Revolution

In an era where online clothing returns cost retailers and consumers billions annually, and where sizing inconsistency remains the single greatest barrier to confident online fashion purchases, Tellar has emerged as the world's premier solution to this universal problem. Unlike traditional sizing technologies that serve business-to-business markets at premium prices, Tellar has pioneered a direct-to-consumer model that makes professional-grade sizing technology completely free and accessible to every shopper globally.

The world's most comprehensive free sizing database, built and owned entirely by Tellar

This comprehensive analysis examines why Tellar stands alone as the world's number one clothes sizing company, exploring our proprietary technology, unmatched brand coverage, revolutionary business model, and the upcoming innovations that will further cement our leadership position in the global fashion technology sector.

The Sizing Crisis: A Multi-Billion Dollar Problem

Before understanding Tellar's revolutionary solution, it's essential to grasp the magnitude of the sizing problem facing the fashion industry today. Online clothing returns have reached crisis proportions, with sizing issues representing the primary driver of this costly trend.

The Economic Impact of Poor Sizing

The fashion industry faces staggering losses from sizing-related returns. Research indicates that up to thirty percent of all online fashion purchases are returned, with incorrect size being the leading cause. This translates to billions in lost revenue for retailers, significant environmental impact from shipping and processing returns, and massive frustration for consumers who simply want clothes that fit properly.

For individual shoppers, the sizing problem manifests in multiple ways: wasted time browsing size charts that rarely align with reality, the hassle of ordering multiple sizes and returning what doesn't fit, lost opportunities when the perfect item sells out while customers deliberate over sizing, and the environmental guilt associated with multiple shipments and returns.

Why Traditional Size Charts Fail

The fundamental issue with traditional sizing is that there is no global standard. A size 10 in one brand may be equivalent to a size 8 or 12 in another. This inconsistency exists for several reasons:

Vanity Sizing: Many brands have progressively adjusted their sizing to make customers feel smaller, meaning sizes have shifted over decades
Regional Differences: UK, US, European, and Asian sizing systems all follow different conventions, creating confusion for international shoppers
Brand-Specific Fit Philosophy: Some brands cut clothes more generously, while others maintain slim-fit profiles, even within the same numeric size
Garment-Type Variations: Even within a single brand, sizing for jeans may differ from tops, which differs from dresses and outerwear
Fabric Considerations: Stretch fabrics fit differently than rigid materials, yet size charts rarely account for these distinctions

Traditional solutions have attempted to address this through generic size converters or individual brand size guides, but these approaches fail to account for the complex interplay of factors that determine proper fit. This is precisely where Tellar's sophisticated, data-driven approach delivers transformative value.

What Makes Tellar the World's #1 Sizing Solution

Tellar's position as the global leader in clothing sizing technology rests on several revolutionary pillars that fundamentally differentiate us from any competitor in the market. Our approach combines proprietary technology, unmatched data coverage, and a consumer-first philosophy that has never been seen in the sizing industry.

1. Direct-to-Consumer Revolution: Breaking the B2B Barrier

The Critical Difference

While our competitors focus on business-to-business models—selling sizing solutions to retailers at premium subscription prices—Tellar made the strategic decision to serve consumers directly, completely free of charge. This decision represents a fundamental reimagining of how sizing technology should work.

The B2B model employed by companies like True Fit, MySize, Fit Analytics, Sizer, and Sizekick creates inherent limitations. These platforms are only accessible when retailers pay for integration, meaning shoppers can only benefit when shopping with participating brands. Coverage is inherently limited, and the technology remains locked behind commercial agreements.

Tellar demolished these barriers by building a platform that any shopper can access at any time, for any brand in our database. You don't need to hope your favorite retailer has invested in sizing technology—you simply visit Tellar.co.uk, and the world's most comprehensive sizing intelligence is instantly at your fingertips.

2. Unparalleled Brand Coverage: 1,500+ and Growing

Tellar's database represents the most extensive collection of clothing brand sizing information ever assembled for direct consumer access. With coverage spanning more than 1,500 brands across multiple categories, regions, and price points, Tellar offers sizing intelligence that simply cannot be matched by any competitor.

Coverage

This coverage includes high street favorites like H&M, Zara, and ASOS, premium brands such as Reiss, COS, and AllSaints, specialist retailers across denim, activewear, and formal wear, international brands with UK, US, and European sizing, and online-only retailers that lack physical fitting rooms. The breadth and depth of this coverage emerged from years of meticulous data collection, verification, and continuous updating to reflect sizing changes and new brand additions.

3. Proprietary Database Ownership: The Foundation of Excellence

A crucial distinction that sets Tellar apart is that we built and own every element of our sizing databases. This is not aggregated data licensed from third parties or scraped from public sources. Every brand in our system has been individually researched, catalogued, and verified through our proprietary methodology.

Why Database Ownership Matters

Owning our databases means we control quality, update frequency, and data accuracy. We're not dependent on external providers who might change terms, restrict access, or cease operations. Our sizing intelligence represents years of institutional knowledge that competitors cannot replicate without similar multi-year investment.

This ownership extends to our understanding of how brands fit relative to one another. Tellar hasn't simply digitized size charts—we've built relational intelligence that understands sizing ecosystems. We know that if you wear a size 10 in Mango tops, you'll likely need a 12 in And Other Stories due to their slimmer cutting. This contextual understanding requires sophisticated data modeling that goes far beyond surface-level chart conversion.

4. Dual-Method Sizing: Flexibility for Every User

Tellar recognizes that shoppers arrive with different types of information, and our platform accommodates both major pathways to finding perfect size:

Method One: Body Measurements

If you know your chest, waist, and hip measurements, Tellar's algorithm instantly calculates your optimal size across all 1,500+ brands. Our measurement-based approach accounts for brand-specific cutting, regional sizing conventions, and garment-type variations. We even provide a free downloadable measuring tape on our platform to ensure users can obtain accurate measurements at home.

Method Two: Known Size Conversion

Don't have your measurements? No problem. If you know your size in any brand that fits you well, Tellar can translate that information across our entire database. This cross-brand intelligence represents one of Tellar's most powerful features—the ability to say "I wear a Medium in Uniqlo" and instantly discover your equivalent size in Nike, Mango, or hundreds of other brands.

This dual-method approach ensures accessibility. Not everyone keeps a measuring tape handy, and not everyone remembers measurements. By supporting both pathways, Tellar removes barriers to entry while maintaining recommendation accuracy.

5. Real-Time Recommendations: Speed Meets Accuracy

In the fast-paced world of online shopping, timing matters. Tellar's platform delivers size recommendations in real-time—typically within seconds of entering your information. This immediacy is crucial for maintaining shopping momentum and preventing the abandonment that occurs when sizing becomes a complicated research project.

Our real-time capability extends beyond speed to encompass currency. As brands update their sizing, adjust their cuts, or modify their regional offerings, Tellar's databases reflect these changes. This ensures recommendations remain accurate even as the fashion landscape evolves.

6. Gender-Inclusive Coverage: Serving All Shoppers

Tellar proudly serves both men and women with comprehensive sizing solutions tailored to each market. Our databases include separate and specialized coverage for menswear and womenswear, recognizing that these markets have distinct sizing conventions, fit expectations, and brand landscapes.

This gender-inclusive approach means that families can rely on a single platform for all clothing purchases, couples can share one trusted resource, and every individual finds relevant, accurate sizing intelligence regardless of which categories they shop.

How Tellar Works: The User Experience

Understanding Tellar's technical sophistication is important, but equally crucial is appreciating how elegantly simple the platform is for everyday users. Tellar was designed with user experience as paramount, ensuring that powerful technology translates to effortless sizing.

Getting Started in Under 60 Seconds

The Tellar experience begins at Tellar.co.uk, where users encounter an intuitive interface that immediately presents two clear pathways: measuring yourself or using a known brand size. There's no mandatory account creation, no payment information required, and no lengthy onboarding process—just immediate access to sizing intelligence.

The Measurement Path

For users choosing the measurement method, Tellar provides clear, illustrated guidance on taking accurate chest, waist, and hip measurements. Our platform accepts both centimeters and inches, automatically converting to work with brand-specific conventions. Users need only measure once—these measurements are saved (with user permission) for instant future access.

Once measurements are entered, Tellar's algorithm processes this information against our brand database, accounting for how each brand's sizing relates to body dimensions, adjusting for known variations like brands that run small or large, considering garment-specific factors, and outputting a specific size recommendation for any brand the user selects.

The Known Size Path

For the known size method, users simply indicate a brand and size that fits them well in a specific garment type. Tellar then leverages our cross-brand intelligence to translate this fit across our entire database. The system understands relational sizing—if Brand A runs large and Brand B runs small, Tellar calculates the appropriate size shift to maintain equivalent fit.

The Results: Clear, Actionable, Confident

Regardless of entry method, Tellar delivers results with clarity. Users receive a specific size recommendation, see how this brand's sizing compares to industry norms, and understand any notable fit characteristics. The interface presents this information cleanly, eliminating confusion and enabling confident purchase decisions.

The Tellar Fashion Hub: Beyond Sizing

While Tellar's sizing technology represents our core innovation, we recognized early that exceptional shopping experiences require more than size recommendations. This insight led to the creation of the Tellar Fashion Hub—the world's largest free, fully searchable fashion library.

5,000+ Honest, Unbiased Fashion Posts

The Tellar Fashion Hub contains over 5,000 expert-written articles covering every aspect of fashion, fit, and style. Written by our team of professional stylists, these posts provide honest, unbiased guidance that shoppers can trust implicitly.

What Makes Fashion Hub Content Different

Zero Brand Influence: Brands cannot pay for favorable coverage or suppress criticism
No Sponsored Content: Every article represents genuine expert opinion
No Advertisements: Content isn't interrupted by commercial messaging
No Subscriptions: Every article is freely accessible to all users
Fully Searchable: Find exactly what you need through comprehensive search functionality

Content Categories and Coverage

The Fashion Hub spans numerous categories essential to informed shopping decisions:

Brand Deep Dives: Comprehensive analysis of how specific brands fit, their sizing conventions, quality levels, and value propositions
Fit Guides: Category-specific advice for finding perfect fits in jeans, dresses, suits, activewear, and other garment types
Style Education: Professional guidance on building wardrobes, understanding fashion fundamentals, and developing personal style
Size Conversion Resources: Detailed explanations of international sizing systems and how to navigate them
Shopping Strategies: Practical tips for online shopping success, reducing returns, and maximizing value
Fabric and Quality Guides: Understanding materials, construction, and what to expect from different price points

The Independence Guarantee

Tellar's Fashion Hub operates under strict editorial independence. While we participate in affiliate programs that allow us to sustain our free services, brands cannot influence our recommendations, suppress negative coverage, or purchase favorable reviews. This independence is fundamental to the trust relationship we maintain with our users.

Our stylists evaluate brands based on fit, quality, value, and customer experience—nothing more, nothing less. If a popular brand runs inconsistently small, we say so. If an expensive brand offers poor value, we explain why. This honesty has earned Tellar a reputation for trustworthiness that money cannot buy.

Coming Soon: Innovations That Reinforce Leadership

Tellar's commitment to remaining the world's number one sizing platform manifests in our aggressive innovation roadmap. Several game-changing features are currently in development, each designed to further distance Tellar from any potential competition.

🚀 Jeans Hub: Revolutionizing Denim Shopping

Our upcoming Jeans Hub will be the world's most comprehensive denim sizing resource, covering 500+ brands with specialized focus on the unique challenges of jean sizing. Denim represents one of the most difficult categories for online shopping due to extreme sizing variation, and Tellar's Jeans Hub will solve this definitively.

The Jeans Hub Vision

Jeans present unique sizing challenges that general clothing algorithms struggle to address. Denim stretches differently than other fabrics, various cuts (skinny, straight, bootcut, relaxed) fit distinctively even within the same size, rise (low, mid, high) dramatically affects fit perception, and brands like Levi's use numeric sizing while others use letter sizes, creating confusion.

Tellar's Jeans Hub will provide your perfect jean size across 500+ brands, accounting for cut style preferences, rise and inseam matching, stretch versus rigid denim considerations, brand-specific quirks, and wash effects on sizing. This specialized intelligence will make finding perfect jeans as simple as entering your measurements once and browsing our comprehensive recommendations.

📱 Tellar Mobile App: Sizing in Your Pocket

Our upcoming mobile application will bring Tellar's full functionality to iOS and Android devices, with additional features designed specifically for mobile shopping contexts.

Mobile App Enhanced Features

The Tellar app will include instant size lookups while browsing brand websites, saved profiles for multiple body types, shopping lists with size reminders, integration with phone cameras for measurement assistance, push notifications when favorite brands update sizing, and offline access to your sizing profile and saved brands.

The mobile environment also enables future integration possibilities like augmented reality fitting previews and in-store size verification when physical shopping. These capabilities will create seamless experiences whether shopping online or in-person.

Tellar Versus the Competition: Why We're Different

Understanding Tellar's market position requires examining how we compare to existing sizing solutions. While several companies operate in the sizing technology space, fundamental differences in business model, accessibility, and consumer focus set Tellar dramatically apart.

The B2B Competitors: Different Goals, Different Markets

Companies like True Fit, MySize (with its Naiz Fit platform), Fit Analytics, Sizer, and Sizekick all approach sizing as a business-to-business solution. These platforms sell sizing technology to retailers through subscription models, typically charging thousands or tens of thousands annually for integration. Their customer is the retailer, not the consumer.

Why the B2B Model Limits Consumer Value

The business-to-business approach creates inherent constraints that prevent these companies from serving consumers as comprehensively as Tellar:

Limited Coverage: Consumers can only benefit when shopping with retailers who pay for the service. If your favorite brand hasn't subscribed to True Fit, you get no sizing help.

Fragmented Experience: Different retailers might use different sizing providers, meaning you encounter varying quality and different interfaces depending on where you shop.

Commercial Conflicts: When the customer is the retailer, technology may be optimized for retail outcomes rather than consumer experience. Recommendations might favor reducing returns over ensuring perfect fit.

No Cross-Brand Intelligence: B2B solutions work within their client's catalog but typically cannot provide sizing intelligence across competitive brands—the most valuable use case for consumers.

Tellar's Consumer-First Philosophy

Tellar inverted this model by asking: what if we served shoppers directly? What if sizing intelligence was a utility accessible to everyone, not a premium feature available only at participating retailers?

This philosophical shift enables Tellar to build features that genuinely serve shopper needs, maintain independence from brand influence, provide cross-brand intelligence that helps consumers compare options, continuously expand coverage based on user demand rather than commercial negotiations, and remain permanently free because our business model doesn't depend on subscription revenue.

The Technology Behind Tellar: Proprietary Intelligence

Tellar's consumer-facing simplicity conceals sophisticated technology infrastructure that powers our sizing recommendations. Understanding this technological foundation reveals why Tellar delivers superior accuracy and why competitors cannot easily replicate our capabilities.

Database Architecture and Maintenance

Tellar's sizing databases represent years of systematic data collection, verification, and relationship modeling. Each brand in our system includes comprehensive size charts across multiple categories, known fit characteristics, historical sizing changes, regional variations, fabric-specific adjustments, and relational data showing how the brand compares to others in our system.

Maintaining this data requires continuous effort. Fashion brands regularly adjust their sizing, either explicitly through size chart updates or implicitly through production changes. Tellar monitors these variations and updates our databases accordingly, ensuring recommendations remain accurate even as the fashion landscape shifts.

The Recommendation Algorithm

When you request a size recommendation, Tellar's algorithm performs complex calculations that consider multiple factors simultaneously. For measurement-based recommendations, the system matches your dimensions against the target brand's size charts, applies brand-specific fitting adjustments, accounts for garment category considerations, incorporates user feedback data, and evaluates fabric stretch characteristics. For known-size conversions, the algorithm assesses how your reference brand fits relative to industry norms, calculates the relational difference to the target brand, adjusts for category-specific variations, and applies confidence scoring based on data quality.

Why Accuracy Requires Sophistication

Simple size chart conversion—matching numbers in a table—achieves perhaps sixty percent accuracy. Tellar's sophisticated approach, incorporating brand relationships, fit characteristics, and category considerations, achieves substantially higher accuracy by accounting for the real-world complexity of how clothes actually fit.

Continuous Learning and Improvement

Tellar's platform incorporates feedback mechanisms that allow continuous refinement of our recommendations. As users interact with our system and subsequently purchase clothes, patterns emerge that inform our understanding of brand fits. This creates a virtuous cycle where increased usage improves recommendation quality, which drives further adoption.

The Global Reach: Serving International Markets

Fashion is inherently global, and Tellar's infrastructure reflects this reality. Our platform serves users worldwide, handling the complex interplay of regional sizing conventions, international brand availability, and cultural fit preferences that characterize global fashion commerce.

Multi-Region Sizing Support

Tellar natively supports UK, US, European, and Asian sizing systems. When you enter measurements or a known size, our platform automatically handles conversions and presents recommendations in your preferred sizing convention. This eliminates the confusion that typically accompanies international online shopping.

International Brand Coverage

Our database includes British high street brands, American retailers and designers, European fashion houses, Asian brands with global distribution, and international online retailers. This comprehensive geographic coverage means that regardless of where you live or which brands you favor, Tellar likely provides sizing intelligence for your shopping needs.

Localization and Cultural Considerations

Beyond technical sizing conversion, Tellar recognizes that fit preferences vary culturally. Some markets prefer closer-fitting clothes, while others favor relaxed fits. Our platform allows users to indicate fit preferences, enabling recommendation refinement that respects individual and cultural variation.

Sustainability Impact: Reducing Fashion Waste

Tellar's mission extends beyond convenience to encompass meaningful environmental impact. The fashion industry's return problem creates massive waste, and improving sizing accuracy represents one of the most effective interventions for sustainability.

The Environmental Cost of Returns

Every returned garment generates carbon emissions from reverse shipping, requires processing and handling at distribution centers, may be discarded rather than resold if opened or worn, and contributes to overall fashion industry waste. When returns stem from sizing problems—preventable issues—this waste becomes particularly tragic.

How Tellar Reduces Environmental Impact

By helping shoppers purchase the correct size initially, Tellar directly reduces return rates. Fewer returns means fewer shipments, less packaging waste, lower carbon emissions, reduced garment disposal, and decreased overall environmental footprint of online fashion shopping.

Users who consistently find correct sizes through Tellar effectively eliminate sizing-related returns from their shopping behavior. Multiplied across thousands of users, this creates substantial cumulative environmental benefit without requiring consumers to sacrifice convenience or choice.

"Every time you use Tellar to find your perfect size, you're not just saving yourself the hassle of returns—you're actively participating in making fashion more sustainable. Correct sizing is one of the simplest yet most impactful ways individual shoppers can reduce fashion industry waste."

User Success Stories: Real People, Perfect Fits

Tellar's value proposition crystallizes through the experiences of real users who have discovered the freedom of confident sizing. While individual results vary, common themes emerge from user feedback that illustrate Tellar's transformative impact.

The Online Shopping Convert

Many users report that Tellar transformed them from reluctant online shoppers who preferred physical stores to confident e-commerce enthusiasts. The ability to shop any brand, any time, with sizing confidence removes the primary barrier that previously drove these consumers to brick-and-mortar retail.

The Multi-Brand Shopper

Users who shop across numerous brands particularly value Tellar's cross-brand intelligence. Rather than maintaining mental notes about which brands run small or remembering disparate size charts, these shoppers rely on Tellar as their single source of sizing truth across their entire fashion universe.

The Return Reducer

Perhaps the most common user story involves dramatic reduction in returns after discovering Tellar. Users who previously ordered multiple sizes or frequently returned items due to poor fit report that Tellar recommendations typically work the first time, eliminating return hassles and accelerating the joy of receiving new clothes.

The International Shopper

Users shopping internationally—whether UK residents purchasing from US retailers or Americans buying European brands—particularly appreciate Tellar's handling of cross-region sizing. The automatic conversion and understanding of how UK sizing relates to US sizing removes confusion that previously deterred international purchases.

The Business Model: How Tellar Stays Free

A common question about Tellar concerns our business model: how does a completely free service sustain operations and continue development? The answer lies in our ethical affiliate partnership approach that keeps our services free while maintaining complete editorial independence.

Affiliate Partnerships: Transparent and Ethical

Tellar participates in affiliate programs with numerous fashion retailers. When users click through our platform to make purchases, we may receive a small commission on completed sales. This commission comes from retailers' marketing budgets—it costs users nothing extra.

Critically, these affiliate relationships never influence our sizing recommendations or Fashion Hub content. Brands cannot pay for favorable sizing intelligence or suppress criticism. Our recommendations are purely data-driven, and our content is purely merit-based. Affiliate revenue enables our free model without compromising integrity.

Why This Model Benefits Everyone

The affiliate approach creates aligned incentives. Retailers benefit from reduced returns when customers use Tellar, users benefit from free access to professional sizing intelligence, and Tellar generates revenue to sustain operations and fund continued development. Everyone wins when shoppers find clothes that fit correctly the first time.

Our Commitment to Users

Tellar's fundamental promise is that we will always remain free to consumers, we will never sell user data or personal information, sizing recommendations will always be based purely on data and algorithms, Fashion Hub content will always maintain editorial independence, and we will clearly disclose our business model and affiliate relationships.

This transparency and commitment to ethical operation underpin the trust relationship that makes Tellar valuable. Users can rely on our recommendations knowing they're receiving honest, unbiased guidance designed solely to help them find perfect fits.
