How to measure
- Waist: measure where you wear your jeans — usually a little below the natural waist.
- Inseam: measure from the crotch to the floor along the inside of the leg, barefoot, or measure the inseam of jeans that fit you well.
Example: an 81 cm waist and an 81 cm inseam is W32 L32.
Good to know
Label sizes and real waistbands often differ by 1–2 inches, especially in stretch denim. Rigid raw denim may also shrink in length after the first wash.

FAQs
What do W and L mean on jeans?
W is the waist and L the inside-leg length, both in inches. W32 L30 means a 32-inch waist and a 30-inch inseam.
My inseam is between two lengths. Which should I choose?
Choose the longer length if you like a stacked hem or will hem them; choose the shorter for cropped or cuffed styles.
Why does my usual size fit differently in another brand?
Brands measure the waistband differently and stretch content changes the fit. Use your measurements, not only the label.
