What size strap should you choose for your Apple Watch?
Which size of strap to choose for your Apple Watch?
On our site, we offer two strap sizes to fit all Apple Watches:
• 42 mm
• 46 / 49 mm
However, Apple has changed the case sizes over the generations, which can be confusing. Here is a clear guide to help you choose the right strap.
Apple Watch & strap size matching

42 mm |

42 mm / 44 mm / 45 mm / 46 mm / 49 mm (Ultra) |
46 / 49 mm |
Why this matching?
Apple has always maintained two case sizes for its watches, with compatibility across several generations:
• The 38 mm, 40 mm, 41 mm and now 42 mm (Series 10) models share the same attachment width and are therefore compatible with our 42 mm straps.
• The 42 mm (previous generation), 44 mm, 45 mm, 46 mm and 49 mm (Ultra) models have a wider attachment and require a 46 / 49 mm strap.
