Belt Size for a 40" Waist
Belt Size for a 40" Waist — belt size, EU equivalent and letter size.
Waist 40" → Belt 42" (107 cm)
Belt size is your trouser waist + 2" so the middle hole sits comfortably.
Belt size = trouser waist + 2 inches. On a 5-hole belt, the middle hole is the intended fit; the outer two holes allow for adjustment. Measure at your trouser waistband, not your natural waist.
Belt size breakdown:
| Measurement | Value |
|---|---|
| Trouser waist | 40" (102 cm) |
| Belt size (US/UK) | 42" |
| EU belt size | 107 cm |
| Letter size | XL |
