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 standard lug widths like 18mm, 20mm, or 22mm.

📐 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.
