Belt Size Guide

Belt sizes don’t match waist sizes exactly: a men’s belt is usually labelled about 2 inches larger than the pant size, so that the buckle fastens on the middle hole. This guide works out your size three ways — from your pant size, from a waist measurement, or from a belt that already fits — and converts between inches, centimetres and letter sizes.

How belt sizes work

A belt’s size is normally the length from the fold where the leather meets the buckle to the middle hole (on a five-hole belt, the third hole). That way, a belt fits with room to tighten or loosen by a couple of holes. Because a belt goes around your trousers rather than your body, and sits a little lower than the waistband label suggests, men’s belts are commonly sized about 2 inches (5 cm) larger than the pant waist size: 34-inch jeans usually need a 36-inch belt.

Letter sizes vary between brands; use inches or centimetres where possible.

Three ways to find your size

1. From pant size — add 2 inches to your trouser waist size for most men’s and unisex belts (1 inch for kids).
2. From a belt that fits — lay it flat and measure from the fold at the buckle to the hole you use most. That number is your belt size.
3. From your waist — measure around your trousers where the belt will sit, then add about 2 inches. For dress trousers worn at the natural waist, this may be higher than your jeans size suggests.

Worked example

Your jeans are size 34. Adding 2 inches gives a 36-inch belt, which is about 91 cm and often labelled L or size 90 in European sizing. On that belt, the distance from the buckle fold to the middle hole is 36 inches, so you’ll have two holes either side for adjustment. If you’ve lost weight and your old belt fastens on the last hole at 34 inches, a 34 belt will now fit better.

Women’s belts

Women’s belts are often sized S, M and L or by dress size, and fashion belts may be worn at the natural waist, on the hips or over dresses. A belt worn at the waist needs to match your waist measurement plus a little ease; a hip belt needs your hip measurement. Always check the brand’s chart and consider where you’ll wear it.

Kids’ belts

Children’s belts usually run from about 20 to 30 inches and are often adjustable or elastic. Measure around the trousers the child will wear, or add about an inch to their waist size. Adjustable-buckle and stretch belts allow room to grow.

Choosing a belt

• Width: about 1.25–1.5 in (32–38 mm) for jeans, 1–1.25 in for dress belts — check your belt loops.
• Dress belts are thinner and usually match shoe colour.
• Full-grain leather lasts longest; bonded leather is cheaper but can peel.
• Ratchet (track) belts adjust in small steps without holes.
• Stretch and woven belts can fasten anywhere along their length.

Converting between sizing systems

European belt sizes are usually given in centimetres in steps of 5 and measured the same way — from the buckle fold to the middle hole.

Buying a belt as a gift

If you can’t ask, check the size on a pair of the person’s trousers and add 2 inches, or borrow a belt they wear and measure it from the buckle fold to the most-worn hole. Adjustable ratchet belts and stretch belts are forgiving choices when you aren’t sure of the size, and many shops will exchange an unworn belt.

Shortening or extending a belt

• Many jeans belts have a screw or snap at the buckle so you can remove it, trim the strap and reattach it.
• A leather punch adds extra holes, spaced about an inch apart to match the existing ones.
• Ratchet belts can be cut to length at the buckle end.
• Belt extenders exist but a correctly sized belt looks and wears better.
