Belt Size Chart (Men, Women) — Match Pant Size to Belt Length
Pant size + 2 inches = belt size. The simplest sizing rule in apparel. Here's the full chart with US/UK/EU conversions and the width-by-style guide.
The Single Rule
Belt size = pant waist size + 2 inches.
If you wear a 32-waist pant, you need a 34 belt. The 2 inches accounts for belt routing through pant loops and reaching the middle hole — which is the design hole, where the belt is intended to fasten. Standard belts have 5 holes, with the middle one as the target.
Master Belt Size Chart
| Pant waist | Belt size (US) | Belt size (EU cm) | S/M/L |
|---|---|---|---|
| 26 | 28 | 70 | XS |
| 28 | 30 | 75 | XS |
| 30 | 32 | 80 | S |
| 32 | 34 | 85 | S–M |
| 34 | 36 | 90 | M |
| 36 | 38 | 95 | M–L |
| 38 | 40 | 100 | L |
| 40 | 42 | 105 | L–XL |
| 42 | 44 | 110 | XL |
| 44 | 46 | 115 | XL–XXL |
| 46 | 48 | 120 | XXL |
Belt Width by Style
| Width | Style | Best for |
|---|---|---|
| 1.0" / 25mm | Skinny belt | Dresses, women's casual, summer suits |
| 1.25" / 32mm | Dress belt | Suits, dress trousers, formal |
| 1.5" / 38mm | Standard / casual dress | Chinos, casual dress, sport coat |
| 1.75" / 44mm | Casual / Western | Jeans, casual, country/Western |
| 2.0" / 51mm | Wide casual / utility | Workwear, heavy denim, statement belt |
Match belt width to the pant's belt-loop opening. Most dress-pant loops are 1.5\" max; chinos and jeans usually 1.75\". Western belt loops on jeans accept up to 2\".
Women's Belts
| Waist | Belt size (US) | S/M/L (US) | EU cm |
|---|---|---|---|
| 24" | 26" | XS | 65 |
| 26" | 28" | XS–S | 70 |
| 28" | 30" | S | 75 |
| 30" | 32" | S–M | 80 |
| 32" | 34" | M | 85 |
| 34" | 36" | M–L | 90 |
| 36" | 38" | L | 95 |
| 38" | 40" | L–XL | 100 |
Women's fashion belts often have multiple holes for adjustability and may be sized just S/M/L without numerical values. Skinny dress belts (1\" wide) follow the same pant + 2 rule.
How to Measure an Existing Belt
- Lay the belt flat. Don't include the buckle's metal in the measurement.
- Measure from the inner edge of the buckle (where the leather connects, where the prong pierces) to the hole you most often use — usually the middle hole.
- That's your belt size. If you measured to the third hole and the belt has 5 holes, that's the standard "middle hole" measurement.
Don't measure end-to-end of the leather — that includes the tail past the buckle, which is unrelated to size.
International Belt Sizing
| US (in) | UK (in) | EU (cm) | JP (cm) |
|---|---|---|---|
| 28 | 28 | 70 | 70 |
| 30 | 30 | 75 | 75 |
| 32 | 32 | 80 | 80 |
| 34 | 34 | 85 | 85 |
| 36 | 36 | 90 | 90 |
| 38 | 38 | 95 | 95 |
| 40 | 40 | 100 | 100 |
| 42 | 42 | 105 | 105 |
UK uses the same numbers as US. EU and JP convert directly to cm. France sometimes uses a small/medium/large notation alongside cm.
Common Mistakes
Buying belt = pant size
A 34 belt is too small for 34 pants. Always pant + 2.
Sizing for the smallest hole
If you fasten at the smallest hole (closest to the buckle), the belt is too big. Buy a smaller belt and fasten at the middle hole.
Sizing for the last hole
If you fasten at the last hole, the belt is at the limit. Buy one size up so you have room in both directions.
Buying belts wider than the pant loops
Most dress-pant loops fit up to 1.5\" only. A 1.75\" belt won't pass through. Always check loop opening.
FAQs
What size belt should I buy?
Pant waist + 2 inches.
How is belt length measured?
From buckle prong (or inner buckle edge) to the middle hole.
Should I size up or down for a belt?
Up if between sizes — you can punch a smaller hole, you can't lengthen leather.
What's the difference between dress and casual belts?
Width and finish. Dress 1–1.25", casual 1.25–1.75". Same sizing rule.
How do US belt sizes convert to EU?
EU = US × 2.54, rounded to nearest 5. US 34 ≈ EU 85.
How long should the belt tail be?
4–6 inches past the buckle when fastened at middle hole.
