Belt Length Calculator

Work out the strap length to cut for a belt, from the waist measurement, the buckle and the tip you want.

Waist measurement in

Measured over the trousers or the layer the belt will be worn on, not against the skin.

Ease in

The comfortable overlap between the buckle and the strap. Two inches is usual, three for a heavy belt.

Buckle type

Extra tip beyond the last hole in

The tail hanging past the keeper. Four to six inches is normal for a jeans belt.

Number of holes

Hole spacing in

One inch is the traditional spacing, giving two inches of adjustment either side of the centre.

Belt width in

Measure the inside of the buckle frame, not the outside.

Leather thickness mm

A thick strap takes up space inside the buckle, so a wide strap plus a thick leather may not thread.
