Apple Watch Band Size Chart mm: Do All Apple Watches Use the Same Bands?


One of the standout features of the Apple Watch is its customisable nature, with interchangeable bands that let users switch up the look and feel of their watch. However, a common question arises: Do all Apple Watches use the same bands? In this blog, we’ll explore Apple Watch band compatibility across different models, explain the Apple Watch band size chart mm, and guide you through picking the perfect band for your watch.

Do all Apple Watches use the same bands?

The short answer is no, not all Apple Watch bands fit every model. However, many bands are compatible across different series, especially when they fall within the same size range. I've explained here in detail how Apple Watch Bands are interchangeable between series, not sizes.

Apple Watch cases come in different sizes, primarily measured in millimeters (mm), and these sizes determine the band compatibility. Here’s a quick overview:

Apple Watch Band Compatibility Explained

Apple Watch bands are typically divided into two main categories:

  1. 38mm, 40mm, and 41mm bands are interchangeable. If you have an older Apple Watch with a 38mm case, you can still use newer bands designed for the 40mm or 41mm models.
  2. 42mm, 44mm, and 45mm bands are also compatible with each other. So, if you have a 42mm Apple Watch from Series 1-3, you can use bands from the latest 44mm or 45mm models, like those from Series 7, 8, or 9.

This overlap in compatibility makes it easier to switch bands when you upgrade your watch.

How to Choose the Right Band for Your Apple Watch


When selecting a band for your Apple Watch, make sure to consider the case size of your watch and ensure the band matches the compatible size range. For example:

  • If your watch is 38mm, choose a band that fits 38mm, 40mm, or 41mm.
  • If your watch is 42mm, look for bands designed for 42mm, 44mm, or 45mm models.
