Strap Sizing Guide

Watches come in all shapes and sizes, and might use a strap as narrow as 12mm, or as wide as 28mm. Identifying the correct size needed for your watch is simple, and will ensure the perfect fit.

Strap Width

The width of a watch strap (given in millimeters/mm) corresponds to the inner opening of the watch "lugs," known as the lug width. The lug width for any given watch can typically be found on the manufacturer's or retailer's website. Likewise, you can measure the lug width easily using a caliper or a ruler.

If you happen to have a watch that has an odd-numbered lug width, you are not out of luck. We carry a selection of 19mm watch straps and 21mm watch straps in our store. If you are looking for a leather strap for a odd sized lugs, drop us an email with what watch you have and which strap(s) you are interested in, and we can make a recommendation regarding up-sizing or down-sizing.

Wrist Size

You can easily measure your wrist size using a cloth tape measure. Alternatively, a piece of string can be used. Wrap the string around your wrist, and make a mark where the two ends meet. Lay the piece out flat, and measure the distance from the end to your mark.

Note: The approximate range of wrist size fitments listed above are as measured using an "average" watch: 40mm case, 47mm lug-to-lug distance. The wearable size of a strap will be affected by the size of the watch, the shape of the lugs, the thickness of the strap, and your personal preference for tightness.
