Here’s how to choose your case size.
You may want to consider the weight of the case and the size of your wrist. The 41mm case is lighter. The 45mm case has more pixels, which means text and buttons are larger for easier tapping, typing, and swiping. Ultimately though, it’s about your desired look and feel.
