Frequently Asked Questions
Everything you need to know about sizing.
The first number (32) is your waist measurement in inches. The second number (30) is your inseam — the inside leg length in inches. Always measure in that order: waist × inseam.
Subtract 10 from the EU size to get the US waist size. For example, EU size 42 equals a US size 32. For women's pants, the conversion varies by brand, but EU 38 generally equals US size 8.
A 32-inch waist is a US size 32 in men's pants, a European size 42, and a UK size 32. In women's pants, a 32-inch waist corresponds approximately to a US size 12 or EU size 42.
Men's jeans and pants typically use the same waist-by-inseam sizing (e.g., 32×30). Women's jeans often use a single number (e.g., size 28) that represents the waist in inches, while dress pants use a different US number system (0–20).
A 36-inch waist is a US size 36 in men's pants (EU 46, UK 36). In women's sizing, a 36-inch waist is approximately a US size 16 or EU size 46.
Wrap a soft measuring tape around the narrowest part of your waist, about 1 inch above your belly button. Keep the tape level and snug — not tight. Round to the nearest inch for your pants size.
