How to Measure a Watch Strap
The easiest way to measure a watch strap is simply to take a ruler and check all important dimensions. The most important one is the width. It should be measured at the watch end. The watch end is the side of the watch strap which will be connected to the watch. Alternatively you can check the inside of your old strap. Most straps have the sizes imprinted on the inside of the watch strap. The next important dimension is the length of the watch strap. Standard watch straps have two parts; the longer one and the part with buckle (shorter). You can use the same ruler to measure the length of the longer and shorter piece of your watch strap.
