Belt Size
Belt sizes are based on waist measurement plus a standard allowance.
Metric (cm) conversion:
US Belt Size = Waist (cm) / 2.54, rounded to nearest even number
EU Belt Size = Waist (cm), rounded to nearest 5
Imperial (inches) conversion:
US Belt Size = Waist (inches) + 2 (add 2 inches to your pants size)
EU Belt Size = Waist (inches) × 2.54, rounded to nearest 5
Sizing tips:
- Measure around your natural waist where you wear your belt
- Add 2 inches (5 cm) to your trouser waist size for belt size
- A belt should fit comfortably on the middle hole
- Standard belts have 5 holes, about 1 inch apart
