Stop Guessing Your Size (It’s Not Your Fault)

If you’ve ever bought the same size in two stores and ended up with one too tight and one falling off your shoulders—you’re not alone.

Sizing is broken.

Every brand does it differently, and unless you’ve got time to read every size chart (spoiler: you don’t), shopping is a gamble.

That’s why we built Tellar.co.uk

Here’s exactly how to find your true size—and never guess again.

Why Sizes Vary So Much

Let’s get this out of the way:

There’s no universal sizing system
Brands use vanity sizing to flatter you
Styles and cuts (tight jeans vs oversized hoodies) feel totally different
Even the same brand can size differently between seasons

Basically: a size 10 means nothing unless you know your own measurements.

Step 1: Take Your 3 Key Measurements

All you need to know is:

Bust – around the fullest part of your chest
Waist – your natural waistline
Hips – the widest part around your bum

Use a soft tape measure (or string and ruler if you’re creative). Write them down in cm or inches.

Step 2: Use Tellar.co.uk to Match Your Size to 1500+ Brands

Once you have those 3 measurements, you can compare your body to any brand’s sizing.

The easiest way to do this?

👉 Tellar.co.uk

We’ve done all the hard work for you. Our database compares your measurements against the official size charts of over 1500 brands, so you’ll know your perfect size before you buy.

Size Conversion Is Confusing (But We’ve Got You)

Wondering if you’re a UK 10, a US 6, or an EU 38?

Here’s a quick guide:

UK	US	EU
6	2	34
8	4	36
10	6	38
12	8	40
14	10	42

Still unsure? Our system auto-converts everything based on your preferred unit—just select CM or Inches when creating your profile.

What About Between Sizes?

If you’re between two sizes, don’t panic. Here’s how to decide:

Want a snug fit? Go smaller (especially if it’s a stretchy fabric)
Want it roomy or relaxed? Go bigger
Check fabric: stretch gives more wiggle room, rigid needs more space

And hey—Tellar’s size advice takes all of this into account already.

Some Brands Just Don’t Fit Right (And We Know That Too)

Here’s what we’ve seen from popular shops:

Zara: Runs small—especially in trousers and dresses
→ https://tellar.co.uk/zara-size-guide
H&M: Inconsistent. Basics run big. Trend pieces run small.
→ https://tellar.co.uk/hm-size-guide
ASOS: Varies depending on sub-label (ASOS DESIGN vs COLLUSION, etc.)

With Tellar.co.uk, you don’t need to remember which ones run small or big—we’ll tell you right there on the results page.
