Find Your Watch Strap Size
A free tool for finding the strap size of a watch. Measure the lug width — the gap between the watch lugs where the strap fits — on a calibrated on-screen ruler, or print a 1:1 paper gauge, and order a replacement strap and spring bars in the right width.
How to find your strap size
1
Pick a mode
Choose "Measure on screen" for a calibrated ruler, or "Print a gauge" to download a paper sheet.
2
Calibrate or print at 100%
On screen, match the blue rectangle to a bank card. On paper, print at Actual size and check the 50 mm bar.
3
Measure the lug width
Measure the gap between the inner faces of the two lugs where the strap sits; the tool snaps it to the nearest standard width.
