Replacement belt straps and buckles work because the buckle is attached with snaps or screws rather than sewn on. Open the fitting, slide the old buckle off, put the new one on, and close it again. The only rule is that the buckle and strap must be the same width.
This means you can keep one good strap and change the buckle to suit your outfit. Or you can keep a favourite buckle and put it on a new strap when the old one wears out.
The three common fittings
1. Snaps
The strap end folds around the buckle bar and closes with two press studs. You open them by hand, so this is the quickest way to swap a buckle. Snap straps are common on casual belts and jeans belts.
2. Screws
The strap folds around the buckle bar and is held by one or two small screws (often called Chicago screws). You need a flat screwdriver or a coin to open them. Screws hold more firmly than snaps, so they suit heavier buckles.
3. Clamp buckles
The buckle has a hinged plate with small teeth that grips the strap end. There are no holes at the buckle end, and you cut the strap to length before fitting it. Ratchet belts work this way. See Ratchet Belt vs Traditional Belt for how they compare, and the 3 main types of ratchet belt buckles for the different clamp styles.
How western buckles attach
Western plate buckles, the large decorative ones, attach the same way as a snap or screw buckle. The strap folds around a bar on the back of the buckle. A hook on the back then goes through one of the belt holes to close it. Browse our western belt buckles.
Match the width first
Measure the width of your strap, then choose a buckle made for that width. A 35 mm (1 3/8″) strap needs a 35 mm buckle. A buckle that’s too wide lets the strap slide around. A buckle that’s too narrow won’t fit at all. We list our belt straps and belt buckles by width, from 13 mm (1/2″) to 50 mm (2″).

How to swap a buckle in four steps
- Open the snaps or unscrew the screws at the buckle end.
- Unfold the strap and slide the old buckle off.
- Put the new buckle on. Push its prong through the slot in the fold, with the prong facing the same way as before.
- Fold the strap back and close the snaps or screws.
Yes, if the buckle is attached with snaps or screws. Open the fitting, swap the buckle and close it again. If the buckle is sewn or riveted on, a cobbler or leather repair shop can remove it and refit the strap with snaps or screws.
No. The buckle must match the strap width, for example 35 mm with 35 mm. The fitting type also matters: snap and screw straps need a buckle with a bar, while clamp buckles need a strap with a plain, uncut end.
Choose a buckle with the same width as your strap. Measure the strap across its face in millimetres or inches. The most common widths are 30–35 mm (1 1/8″–1 3/8″) for dress belts and 35–40 mm (1 3/8″–1 1/2″) for jeans belts.
Yes. Buy a strap in the same width with a snap or screw end, take the buckle off the old strap, and fit it to the new one. This is a cheap way to keep a buckle you love.
