About this chart

These charts apply to ASOS own-brand clothing, not to the other brands sold on the site. ASOS publishes in inches and centimetres: only centimetres are shown here. The Tall fit has the same measurements as the standard chart; the Maternity chart, tights and suit jacket lengths are not reproduced.

Women

UK sizes. According to ASOS, the European size is the UK size plus 28 (UK 10 = EU 38). Letter sizes for lingerie and swimwear are in a separate chart.
