Size guide & compatibility

Every Wristo band comes in two size groups: small and large. Check the case size on the back of your Apple Watch before ordering.

Small

38, 40 and 41 mm. Also the newer 42 mm Apple Watch Series 10 and 11.

Large

42 mm Apple Watch Series 1 to 3. Also 44, 45, 46 and 49 mm.

Do you have a 42 mm Apple Watch Series 10 or 11?

Choose the small size group. This is a newer, smaller case size than the 42 mm on older models.

Finding your case size

Go to Settings > General > About on your Apple Watch. The case size is listed in millimetres.
