Why sizes don't line up cleanly

There's no single worldwide standard for clothing sizes the way there is for, say, screw threads. Each region grew its own numbering, and brands within a region still cut differently. The table here shows the general conversion used across most mainstream charts: for women's sizing, US 0 lines up with UK/Australia 4 and EU 32, moving in step from there.

UK size ≈ US size + 4 · EU size ≈ US size + 32 (women's)

Using it on a product page

  • Show it alongside real measurements. A size label converts less reliably than a chest, waist or hip measurement does. Use the size chart generator for your own product's actual measurements.
  • Note the brand. If you carry multiple brands, say clearly which one a size guide applies to, since a UK 12 in one brand can be a UK 10 or 14 in another.
  • International shoppers convert automatically if you let them. Some themes and apps show a shopper's local size based on their region; check if yours supports it before asking customers to do the math themselves.

Questions people ask

Is a UK 12 the same everywhere?

Not exactly. The conversion here is a common general guide, but two brands both selling a "UK 12" can differ by a size or more. Always check the brand's own chart when one is available.

Why isn't there a kids' clothing row?

Kids' sizing usually runs by age and height rather than a single numbered scale, and it varies even more by brand than adult sizing. A general conversion table risks being misleading, so it's left out here; check the brand's own age or height-based chart instead.

What's the difference between US and UK women's sizes?

UK women's sizes typically run 4 numbers higher than the equivalent US size, so a US 8 is roughly a UK 12.

Does Australian sizing match UK sizing?

Broadly yes for most mainstream brands, which is why they're shown in one column here, though a few brands size Australian sizes closer to the US scale. Check the brand if it matters.
