WATCH BAND MEASURING GUIDE


What Is Watch Band Size?

Watch band or watch strap size is determined by the width of the band end that attaches to the watch. Watches come in many different sizes, therefore the width of the watch strap can vary as well. To determine the appropriate watch band size for your watch, measure it’s lug width (see diagram below).

HOW TO FIND YOUR WATCH BAND SIZE

If you already have a leather band for the watch in question, you can check the back to see if it has a size imprint, shown in millimeters. Otherwise, you will need to find the lug width of your watch, which is the distance between the inside of the lugs on the watch head. You can easily measure it yourself in one of the below three ways.

use digital calipers to measure watch band length

METHOD 1: DIGITAL CALIPERS 

This is the most accurate method. To use, insert the calipers in the space between the lugs and expand to find the exact size.  

Rounding: Rule of thumb for a replacement watch band is that it’s better for the watch band to be tight rather then loose. If you need to round your measurement, rounding up is usually your best bet, as a leather watch strap, rubber watch strap or nylon watch band can be slightly flexible to fit.

use a ruler to measure watch band length

METHOD 2: USE A RULER 

Measure the distance between the lugs with a standard ruler. The same rules apply as above for rounding. If measuring in inches, you'll then need to convert the inches to millimeters. You can use the handy chart below.

HOW TO FIND YOUR WATCH BAND LENGTH

Watch band length is measured in inches and watch bands come in different standard lengths by brand. Use the below charts, showing ranges of standard lengths across all brands we sell, to determine your correct length. 

Note: Not all watch bands are manufactured in every length. 

The formula for finding watch band length is:

WRIST SIZE - WATCH HEAD SIZE = WATCH BAND LENGTH

Pick your watch strap or band type below and follow the simple steps to find your correct length size.

Leather, Nylon & Rubber Strap Length

METHOD 1: USING YOUR EXISTING LEATHER WATCH STRAP

  • If you have an existing leather strap that fits your watch, measure it with a ruler to determine the length. When measuring, only measure the leather parts of the strap, do not include the buckle.

  • If you have an existing leather strap that fits your watch, measure it with a ruler to determine the length. When measuring, only measure the leather parts of the strap, do not include the buckle.

METHOD 2: FINDING THE LENGTH FROM SCRATCH

  • Find your wrist size by wrapping a tape measure or a piece of string around your wrist. Mark where the two ends meet then lay the thread out flat on a ruler and measure the distance. 
  • Next, find your watch head size. The average men’s watch head is 1”-1.5”, but you’ll want to make sure you measure your own to get an accurate measurement. Use a ruler or check the manufacturer for information. 
  • Minus your watch head measurement from your wrist size measurement. This will give you the total watch strap length needed. 
  • Important Note: Not all watch straps are manufactured in every length.
