Accurate Clothing Size: How to Get It Right Every Time

We’ve all been there: scrolling through your favourite fashion website, adding the perfect dress, jeans, or jacket to your cart — and then pausing with a sigh when you reach the size dropdown. What size am I in this brand?

It’s one of the biggest frustrations in online shopping — and the number one reason for returns.

Getting your accurate clothing size shouldn’t feel like guesswork. That’s where tools like Tellar.co.uk come in — giving you real-time, reliable size recommendations across over 1,500 brands in seconds.

Why It’s So Hard to Get the Right Size Online

The biggest reason sizing is so confusing is simple: there is no universal sizing standard.

Here’s what can affect sizing:

Different cutting patterns between brands
Vanity sizing (where sizes are deliberately skewed to flatter the buyer)
Regional differences (UK, US, EU sizes)
Inconsistencies between men’s and women’s sizing
Varying sizing logic across product types (jeans vs. shirts vs. dresses)

As a result, you could be a size 10 in Zara, a size 12 in COS, and a size 8 in H&M — all at the same time.

What Is the Best Way to Find Your Accurate Clothing Size?

To get an accurate clothing size when shopping online, you need one of two things:

Your actual body measurements (chest, waist, hips), or
A known size that fits you well in a trusted brand

Then, you need a smart tool that:

Matches those values to the brand’s real sizing data
Adjusts for brands that run small or large
Provides size recommendations based on fit accuracy — not assumptions

That’s exactly what Tellar.co.uk does — and it’s completely free to use.

Real-World Example: The Size Switch Scenario

Let’s say you wear a size 10 in H&M jeans and want to try Levi’s. Instead of ordering two sizes and hoping for the best, you go to Tellar.

Input: H&M, Size 10
Output: Levi’s – Size 28 (based on actual measurements mapped from H&M’s sizing)
You order one size, it fits perfectly — no return necessary

That’s size accuracy powered by data — not guesswork.

Who Is It For?

Tellar’s accurate clothing size tool is for anyone who shops for clothes online. Whether you’re:

A regular online shopper across brands
A new parent whose body has changed
Shopping for a growing teen
Trying to gift someone clothing
Tired of wasting money on returns

…Tellar is for you.

Why Measurements Alone Aren’t Enough

Measurements are a great start — but every brand interprets them differently. A 70cm waist might be a size 8 in one store and a size 12 in another.

That’s why Tellar’s database maps real brand sizing — so you don’t just match your body, you match the way that specific brand cuts and sizes its clothing.

Tellar uses a powerful sizing engine that combines:

A standardized measurement database
Brand-specific sizing patterns
Real-world user feedback on fit accuracy
Smart logic to account for fit types (regular, slim, oversized)

Everything runs in real-time through a user-friendly interface — with no download required.

Why Accurate Sizing Matters More Than Ever

In a world of online-first fashion shopping:

Returns create unnecessary carbon emissions
Sizing mistakes frustrate customers
Brands lose money and trust

Improving sizing accuracy is good for your wallet, your time, and the planet.
