WATCH STRAP SIZE GUIDE

📏 Width – Lug & Buckle
To determine your watch band size, measure the inside lug width — the space between the lugs where the band attaches to your watch case.
- All measurements are in millimeters (mm).
- Our sizing options are shown as lug width x buckle width (e.g. 20x18mm)
- If you plan to reuse your original buckle, measure the inside width of the buckle. Use our size filters to find the correct lug width x buckle width combination for your strap.
(If you don't plan on using an original buckle, you can skip this measurement and order by "lug size" needed)
Tip: Most smart and traditional watches have even number lug widths like 18mm or 20mm.
📐 Length – Strap Fit
To find the best strap length for your wrist:
-
Measure your wrist circumference, or measure both sides of your current strap (excluding the buckle and watch case).
Strap length is the total of:
-
Long side length + Short side length

Length options vary depending on strap model and width.
