What this tool does
Convert jeans waist sizes between inches, centimetres, EU sizes and — for women — US dress sizes, from standard published jeans charts. W sizes on jeans labels are nominal: many brands cut 1-2 inches larger than the label (vanity sizing). Measure a well-fitting pair laid flat and double the front waist width for your true waist.
