Apple Watch Band Adapters

📏 Width – Lug & Buckle 

• To determine your watch band size, measure the lug width — the space between the lugs where the band attaches to your watch case.

  • All band width measurements are in millimeters (mm).

  • Our sizing is shown as lug width x buckle width (i.e. 20x18mm)

  • If you plan to reuse your original buckle, measure the inside width of the buckle.
    (If you don't plan on using an original buckle, you can skip this part and just order by "lug size" needed)
    

  • Use our size filters to find the correct lug width x buckle width combination for your strap.
    

  📌 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.
