Tool Introduction
The Pants Size Calculator matches your waist measurement to the right international and US pant sizes. Enter your waist in inches or centimeters, choose men’s or women’s, and the tool highlights the recommended row on both size charts - including the hip range, so you can double-check the fit.
Men’s sizes are shown as a US waist in inches (like 32), while women’s sizes use US numeric sizing (like 8). Sizes vary between brands, so use the chart as a starting point and always check the label or the retailer’s own guide.
