Here’s how to choose your case size.

Both case material and size impact weight. 41mm cases are lighter than 45mm and aluminum is lighter than stainless steel. The display on the 45mm case has more pixels, which means that texts and buttons will be larger. Ultimately, the best size depends on your desired look and feel.
