How to Find Your Watch Strap Size

For a watch expert, it's a simple task - you probably don't even need to check your watch. However, for the rest of us, it can seem a little unclear at first. Watch & Strap are here to help, and we have developed this guide to help you find the perfect-sized strap for your watch.

Lug Width

On any website selling watch straps, you will see 'lug width' as a product option. The lug width is the distance between the lugs at the top and bottom of a watch. The most common size is 20mm; however, watches with 18mm, 22mm and 24mm lugs are also common. You can find out the lug width for your watch by either doing a quick Google search for the model or manually measuring it yourself..

Strap Size

The first step to finding the perfect strap length for your wrist is to measure the circumference of your wrist.

The second step is just a little more involved: you will need to determine the usable length of each part of your preferred strap. This should be available on the strap merchant's website.

At Watch & Strap, the buckle side of all our straps is 75mm, with the usable length of the long side being between 55mm and 95mm. This gives a total combined usable length of 125mm-165mm. However, there is one last measurement to consider: the size of the watch itself.

The final step is to measure the distance between the top and bottom lugs of your watch and add this to the strap sizes. This combined total is the ultimate strap length to compare to the circumference of your wrist.
