How to Find Your Size in H&M, Mango, Zara and ASOS – Without Guessing

Finding your size in H&M, Mango, Zara and ASOS shouldn’t require trial and error. But if you’ve ever ordered a Medium that fit like an XS, or a UK 10 that felt more like a 14, you’re not imagining things.

If you’re searching for:
🔍 “How do I know my size in Zara and ASOS?”
🔍 “What size am I in H&M vs Mango?”
You’re in the right place.


The Problem: Every Brand Sizes Differently

Let’s be clear: there is no such thing as a universal size chart.

  • A UK 10 in Zara might be a UK 12 in ASOS

  • A Medium in Mango may feel tighter than Small in H&M

These inconsistencies lead to millions of returns, wasted time, and frustrated shoppers.
