The converter below is pre-loaded with women's UK 6 (US 8). Switch the gender tab or type any UK size to see the matching US, EU and foot-length values.

Frequently asked questions
How do I convert UK shoe sizes to US?
For women, add 2 to your UK size to get the approximate US size (UK 6 ≈ US 8). For men, add 1 to your UK size (UK 9 ≈ US 10). Use the converter above for a precise lookup including half sizes.
Is UK 8 in women's the same as UK 8 in men's?
No. UK sizing uses separate scales for men and women, and the same UK number corresponds to a different foot length depending on gender. Women's UK 8 ≈ US 10; men's UK 8 ≈ US 9. Always check the gender tab before converting.
Are UK kids' shoe sizes the same as adult UK sizes?
No - UK kids' sizing runs from roughly 0 to 13.5 and then restarts at 1 for adults, so a kids' UK 13 is smaller than an adult UK 1. Older children typically transition into adult sizing somewhere between UK 12 and UK 4.
