Strap Sizing

Getting the right size ensures your strap fits perfectly. You need two measurements: your wrist circumference and your watch’s lug width.

Step 1 — Measure Your Wrist

Use a flexible tape measure, or a strip of paper and a ruler. Wrap it around your wrist just below the wrist bone, where you normally wear a watch, and note the measurement in millimetres.

Wrist Size Recommended Strap
Under 160mm Short (S)
160–180mm Standard (M) — most common
180–200mm Long (L)
Over 200mm Extra Long (XL)

Standard strap length is 125mm (long piece) + 75mm (short piece) = 200mm total.

Step 2 — Measure Your Lug Width

The lug width is the distance between the two lugs where the strap attaches to your watch case. Measure the gap with a caliper or ruler and round to the nearest even number (most straps come in 18, 20, 22, 24, 26mm).

Watch Brand / Model Lug Width

Apple Watch 42/44/45mm 42/44/45mm band
Panerai (most models) 24mm
Panerai (large models) 26mm
Bell & Ross BR01/BR03 24mm
