A women's UK shoe size converts to EU through the same foot-length-anchored chart used for US conversions. As a reference point, a UK 6 is an EU 39.
UK women's shoe sizes are two whole sizes below the equivalent US women's number for the same foot (a UK 6 lines up with a US 8), and the EU conversion follows from there: a UK 3 is an EU 36, a UK 6 is an EU 39, a UK 9 is an EU 42.
Some UK retailers shift their half-size EU rounding slightly, so if your UK size sits at a half-size like 6.5, check the foot-length-cm column or use the measure-your-foot tool on the main shoe converter rather than relying on the label alone.

A women's UK 6 is an EU 39, the same physical size as a US women's 8.
The UK number itself is shared across a unisex UK scale, but which US/EU size it maps to depends on whether you’re using the women’s or men’s chart — always pick the right gender first.
Two whole sizes — a UK 6 is a US women’s 8, a UK 8 is a US women’s 10, and so on.
