Sizing conventions vary by brand and by cut — this table shows the standard published conversion. Always check the garment's own size chart when one is available. See how these tables are compiled.
A US 8 women's jeans waist converts to a UK 10 on the standard chart, a two-size gap that holds through the 28in-to-38in waist range shown here — the same offset seen on the general jeans and dress charts on this site.
Denim brands vary more in how they label vanity sizing than most other garment categories, so treat this UK number as a starting point for browsing rather than an exact match — the waist-in-inches figure printed on the tag itself is the more reliable number for denim specifically.
Frequently asked questions
Is women's jeans sizing more inconsistent than other clothing?
Yes, more than most — denim brands have historically used vanity sizing more aggressively than dresses or tops, so the actual waist measurement in inches (often printed on the inside tag) is worth checking against the size number.
