How to find your watch strap size.

WatchWatchWatch - The UK's Watch Strap Specialists


When deciding which watch strap to buy, the first thing to consider is the width. This is the width of the watch strap, in millimetres, at the point where it attaches to the watch. Our most common reason for returns is “I ordered the wrong size”, so getting it right first time will save you time, money and hassle.

You are aiming to totally fill the gap between the lugs, or shoulders, of your watch. You need to carefully measure the gap, and if your gap is 18mm, for example, then you should order an 18mm strap.

Example watch strap size stamped on to back of strapSome watch straps have the size stamped on the back. Check your existing strap and see if there are any markings. If you can see a “18”, for example, stamped anywhere, then a 18mm strap is what you should order.


It is important to get the right length watch strap, so it will be a comfortable fit on your wrist. For leather watchstraps, there are 3 different lengths to choose from, in both ladies’ and men’s sizes

  • Standard
  • XL
  • XXL

Watch Strap Size Diagram ExampleAll our watch strap listings have a detailed size chart at the bottom of the description, so you can get a good idea of the length. We can’t give totally accurate maximum wrist size information, because that is dependent on the length of your watch case. Once the strap is fitted to a watch, the watch itself makes up some of the overall length, so you need to take the pin-to-pin length of your watch into consideration when calculating maximum wrist size of a watch strap.

As well as giving various dimensions of our watch straps, we give a size when buckled up on the last hole (i.e.the biggest size it will go to). If you add the pin-to-pin length of your watch to this measurement, this will give you the most accurate maximum wrist size that the strap will fit as it simulates the watch being fastened up, with the watch attached.

In broad terms, standard length watch straps will be OK for most people. If you consider yourself to have a large wrist, go for an XL watch strap. If you consider yourself to have a really big wrist and struggle to find a watch strap to fit, try an XXL.
