Enter a waist measurement to calculate the recommended belt length, international letter size, and EU belt number.

International Belt Size Converter

Enter your waist measurement in inches or centimetres to see the recommended belt length, plus the nearest international alpha size and European belt number. We add an allowance of roughly 2 inches (5 cm) so the middle hole sits comfortably.

When this converter helps most

Online shopping: translate between US, EU, and alpha sizing before ordering a belt from another region.
Wardrobe styling: plan outfits by comparing existing waist measurements with recommended belt lengths.
Retail assistants: quickly guide customers to the closest size without pulling every belt off the rack.

Fit tips

Measure around the waistband of the trousers you plan to wear—not your natural waist—to match everyday fit.
If you swap between centimetres and inches often, download the summary so you have a reference when shopping in-store.
For reversible or thick leather belts, rounding up gives extra room for layering or seasonal changes.
