Men's Bottoms

Waist and fit conversions for trousers, jeans, and other bottom categories.

Men's bottom sizing is usually straightforward — it's based on waist measurement in inches. The main crosslisting challenge is converting to European sizes, which use a different numbering system.

Reseller tips

  • Men's jeans and trousers are sized by actual waist measurement in inches (US / UK).
  • To convert to EU: add roughly 16 to the inch measurement (32" ≈ EU 48).
  • Always list the inseam length alongside waist size — it's critical for trousers.
  • Pleated and relaxed-fit trousers may be tagged one size larger than the measured waist.
