The math
How to convert UK to W
Women: EU = 2 × W − 18, US = EU − 32, UK = EU − 28, Italian = EU + 4. Men: EU = W + 16, French = W + 8, US and UK = W.
Example: 10 UK = 28 W.
The table below uses Women’s sizes. Switch above and the EU, French, US and UK columns shift.
In practice
When you’d convert UK sizes to jeans waist
A British shop lists UK sizes and the brand label says W. Men: the UK number is the waist, UK 32 is W32. Women: UK 8 is W27, UK 10 is W28, UK 12 is W29 and UK 14 is W30.
Common mistake: Mixing up the women’s UK number with the American one: UK 10 is W28, but US 10 is W30.
Women: UK 6 is W26, UK 8 is W27, UK 10 is W28, UK 12 is W29, UK 14 is W30, UK 16 is W31 and UK 18 is W32. Add 46 and halve; for men there is nothing to calculate.
