US W waist label
About this calculator
Enter the waist number from a US W label. The converter reports that waist measurement in inches and centimetres; it does not predict fit or convert to UK/EU garment labels. Denim sizing and garment measurements vary by brand and style, so check the product chart.
Choose the calculation that matches your task
This page converts an existing W waist number to inches and centimetres. It does not calculate a leg length or convert to universal UK or EU garment sizes. Use the waist-and-inseam tool when you want a W × L reference from measurements.
