A simple +4 rule works for many women's US-to-UK conversions, but measurements should confirm fit.

How to measure before choosing a size

Use a soft tape measure and keep it level, snug, and not compressed against the body.
Measure over light clothing or underwear for apparel; bulky layers can add a full size.
For international conversions, treat the chart as a starting point and check the brand chart before buying.
If one measurement lands between two sizes, choose by garment: prioritize bust/chest for tops, waist and hips for bottoms, and the largest measurement for fitted dresses.

FAQ

How do I convert US women's size to UK?

A common shortcut is to add 4. For example, US 8 is often UK 12.

Is US men's size the same as UK men's clothing size?

Men's chest-based clothing numbers are often similar, but shirts, pants, and shoes use different details.

Do kids US and UK sizes match?

Kids labels can be similar by age, but height and weight are more reliable for ordering.
