How Do I Find My Correct Size?
Finding your correct clothing size shouldn’t feel like a guessing game — but for many people, it does.
Different brands use different sizing standards. A “Medium” in one store could be a “Small” or even a “Large” somewhere else. Measurements vary, terminology changes, and size charts often lack the detail needed to make confident decisions. For online shoppers especially, this inconsistency leads to confusion, incorrect orders, and frequent returns.
So, how do you actually find your correct size?
That’s where Tellar.co.uk comes in.

How It Works
You have two ways to get started:
Option 1: Use Your Measurements

- Tellar compares your measurements with actual size charts from 1,500+ brands.
- It recommends your best-fitting size in each brand, based on your largest measurement — ensuring comfort and accuracy.
Option 2: Use a Size You Already Know
- Select a store where you know your size fits well.
- Choose your usual size in that store.
- Tellar estimates your measurements based on that brand’s sizing data, and then recommends your ideal size across other brands.
