Put your belt on the table and use a tape measure or ruler to measure from the end of the buckle (see picture) to the hole you always wear (comfort hole). This is the waist size. "Optimal fit" in this sense means that your new belt is made so that the buckle pin lands in the middle of the 7 pin holes.

Important: I need your waist size, not the total length of the belt or information from third-party manufacturers!

Alternatively, measure your waist size with a flexible tape measure.
Put on a pair of well-fitting trousers/jeans and make sure that they sit correctly on your waist. Take a flexible tape measure and pull it through the belt loops. The result in cm corresponds to your waist size and therefore also the belt size you need. Don't have a flexible tape measure to hand? No problem - just take a piece of string and pull it through the belt loops. Mark the place where the string 'closes' and then measure the length using a ruler - and you have your waist size/belt size.

The measurement results must then be selected for your desired item in the "Waist size" section. Tap on the box with the desired measurement. If in doubt, always choose the next larger size; a longer belt always fits better and can be shortened depending on the model, unlike a belt that is too short. The hole spacing is 2.0-2.3 cm and 7 holes are used as standard.

If you need a measurement (waist size) for a belt that is not available or need help, please contact me. Note: I am not responsible for any measurement errors on your part.
