Here’s how to choose your case size.
You may want to consider the weight of the case and the size of your wrist. Although the case material greatly impacts the weight, the 41-mm case is lighter than the 45‑mm case. However, the 45‑mm 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.
