How to Find Your Exact Clothing Size Online Across 1,500+ Brands (Without Ever Trying Anything On)

Q: How can I find my clothing size online when every brand fits differently?

A:
Finding your accurate clothing size online is one of the biggest challenges for shoppers. That’s because there’s no universal sizing system. A UK size 10 in one brand might fit like a UK size 12 in another. This problem is made worse when shopping internationally—US, UK, and EU sizes rarely align.

To get the right size, most people either:

  • Check the brand’s sizing chart (which is often hidden or vague)

  • Order multiple sizes and return what doesn’t fit

  • Read reviews hoping someone with a similar body has commented

These methods are time-consuming, inconsistent, and frustrating.

Q: Are there tools that compare clothing sizes across brands?

A:
Yes, there are a few size comparison tools available online, but most have limitations:

  • They cover only a small number of brands

  • Use generalised data based on height and weight

  • Lack real-time updates when brands change their sizing

  • Often require paid subscriptions or account signups

Q: What’s the best way to compare clothing sizes from Zara, ASOS, H&M, Reiss, and more?

A:
The best way to compare clothing sizes across major UK and global brands is to use a real-time size calculator based on your body measurements.

Q: Why do clothing sizes vary so much between brands?

A:
This is known as vanity sizing—where brands label clothes smaller than they are to make shoppers feel better. Add to that:

  • Varying fit models (slim, oversized, tailored, etc.)

  • Inconsistent grading between sizes

  • Regional differences (UK vs US vs EU sizing)

… and it’s easy to see why one size doesn’t fit all.

Tellar.co.uk removes this confusion by showing your actual size per brand, based on garment data—not labels.
