Your belt size should be 2 inches longer than the size of your pants waist. So if you are wearing a size 40” trousers, you will need a 42” belt (105 cm in length). This length refers to the strap length from the buckled belt hole (usually the middle hole) to the end of the strap that is attached to the buckle.
Alternatively, you can work out the size of your new belt from your old belt. Measure from where you always buckle it to the opposite end of the strap (the end that is attached to the buckle), and get the closest size to that.
When buying a plate buckle, remember the throw (distance from chape to hook) adds to the length of your belt.
When Belt Length Is Too Long
If you have a belt that’s the wrong size (or your size has changed since you bought the belt) DO NOT be tempted to gouge a hole on the strap. Punching a hole the strap manually may entail a belt hole that is created out of line with the rest of the holes, resulting in a skewed alignment with your waist when buckled to your trousers. It may also weaken the strap structure and thus shorten the lifespan of the strap.
Check if your belt strap may be removed from the buckle. All 72 Smalldive belts are re-sizeable and re-sizing the belt may be done by loosening the rivet that is affixed to the buckle and cutting the strap to your desired size.
To reattach the buckle to the strap, you will need a leather hole puncher. It is an easy task that seems at first daunting and for that reason we always suggest that you take it to your local leathersmith or cobbler to have the length adjusted properly.

When Belt Length Is Too Long
Dress belts should only have a short tail end. You just want no longer than 5 inches of leather to the left of the buckle when it’s fastened, long enough to tuck through the first or second belt loop or even the loop on the belt itself if it has one. When purchasing for someone or via an online shop err on the side of extra length if the belt can be resized. Do not aim for an adhering fit even if you have a chance to try it on, mainly because a belt fit varies with the trousers. Try on the belt with various trousers in your wardrobe and if the left of the buckle extends beyond 5 inches or more, consider having it resized or changed.
Casual and weave belts can have a little bit more of a tail, although too long will still look awkward. Military-style canvas belts with brass buckles traditionally get their tails docked right down to the buckle.
