Pants Size Converter

Convert waist and inseam between inches and centimeters. When our dataset contains verified rows, match pant labels across regions.

Dataset note: 2026-04-05 · Review target every 90 days. Women's UK/US/EU rows follow ASOS visible 'International single size conversion' plus ASOS waist (cm) from the same women's jeans size chart page. Men's waist inches/cm follow ASOS men's jeans chart; UK waist label is treated as the same inch value as US W for jeans (common W/L retail practice). Men's EU column uses France/Italy-style numbers from the Levi's men's conversion table on size-charts.com (aggregated third-party citing Levi's)—continental EU denim tags also use German-style waist numbers equal to US inches; always confirm on the brand tag.

Jeans flat lay with a soft tape measure along the inseam for waist and length sizing

Frequently asked questions

Where do international pant label conversions come from?
Women's UK/US/EU matches the ASOS women's jeans and trousers size chart (international single size conversion and waist cm on the same page). Men's waist inches and centimetres match the ASOS men's jeans chart. Men's UK uses the same inch waist as US W labels for jeans. Men's EU uses France/Italy-style numbers from an aggregated Levi's conversion table on size-charts.com; continental EU tags are not one single system, so confirm on the brand chart. Japan (JP) appears only when verified rows include JP values.
Does the unit tab convert US pant sizes to EU?
No. The unit tab only converts length measurements between inches and centimeters. Cross-country label matching uses the international labels tab when verified rows are available.
