To measure your wrist size:
- Print our wrist measurement guide. Cut the ruler, wrap it snug, but not tight, around your wrist. Mark the length, lay it flat, and measure with a ruler.
- Use a tailor's ruler, made out of cloth or fabric. Wrap it snug, but not tight, around your wrist. Mark the length.
- Use a string. Wrap it snug, but not tight, around your wrist. Mark the length, then lay it flat and measure with a ruler.
One you know your wrist size, you can easily use our filter to choose straps that will fit your wrist.
To measure your lug size:
- Look on the back of your existing strap. Many watch bands and rubber straps will have the lug size imprinted on the back of one or both of the straps. This is the fastest method and helps to ensure an exact fit.
- Print our measurement guide. Put your watch over the millimeter ruler to determine your watch's lug size.
- Use one of our watch band tools with a printed ruler and use that ruler to determine the lug size.
- Use a metric ruler or calipers, to measure the space between the lugs. An imperial ruler can also be used if you convert inches to millimeters.
- Find your watch specifications online. Google " lug width" (eg, "Citizen Promaster Fugo lug width"). Most manufacturers list the lug-to-lug size on their website product pages (look under specifications or details). Common sizes will be 18mm, 20mm, and 22mm.
- Run it by a watchmaker or jeweler. They will be able to tell you the size between your lugs.
