Brand Size Comparison: Find Your Fit Across 1,500+ Clothing Brands

Have you ever noticed that a size 10 in one brand fits perfectly — but feels too tight or too loose in another? That’s not your imagination — it’s a well-known problem in the fashion world. Clothing sizes vary wildly between brands, and even within the same retailer.

That’s where a brand size comparison tool becomes a game-changer — and Tellar.co.uk is the best free tool to do just that.

With over 1,500 brands in its database, Tellar helps you compare clothing sizes across fashion labels and instantly recommends the right fit for your body or your known size in another brand.

Why Do Clothing Sizes Vary Between Brands?

There’s no single sizing standard in the fashion industry. Every brand defines its own sizing based on:

• Target customer demographics

• Regional sizing standards (UK, US, EU)

• Design style (slim fit, oversized, relaxed)

• Fabric stretch and garment type

That’s why you can be a size 8 in Zara, a 10 in COS, and a 12 in Reiss — all while your actual body measurements remain the same.

What Is Brand Size Comparison?

Brand size comparison is the process of matching your known size in one brand with the equivalent size in another. It’s especially useful when:

• Shopping from a brand for the first time

• Switching between high street and premium retailers

• Trying to reduce returns from incorrect sizing

Rather than relying on vague size charts, you use actual fit data to determine your best size across brands.
