How to Size European Men's Underwear (Without Guessing)

Tailor's measuring tape laid over a white shirt, for measuring underwear size

European brands often run smaller or use number sizes (like 4, 5, 6) or cm. The fix is simple: measure, then trust the brand chart.

Step 1: Measure

Measure around your waist where your underwear sits, with the tape flat but not tight. Write it down in inches and cm.

Step 2: Check the brand's own chart

Every brand is different. Always use the chart on the product page.

  • Olaf Benz: uses number sizes.
  • Example of a US-style chart (Obviously): S 30–32" (75–80 cm), M 33–36" (81–90 cm), L 37–40" (91–100 cm), XL 41–44" (101–110 cm), 2XL 45–48", 3XL 49–52".

Step 3: Think about the cut and fabric

  • Low-rise cuts (bikini, tanga, string) sit lower on the hips, where you may measure bigger or smaller than your waist.
  • Very stretchy fabrics (high elastane) are more forgiving.
  • Between sizes? Obviously suggests going up for relaxed or down for snug. That's a good rule elsewhere too.

Step 4: Know the return policy

Underwear returns are often limited. Check before you buy. (HOM's EU store lists free returns within 30 days; US terms may differ.)
