Here’s how to choose your case size.

The best case size depends on your desired look and feel. Apple Watch Series 10 has the biggest display of any Apple Watch ever. The display on the 46mm case has more pixels than the display on the 42mm case, which means texts and buttons will be larger. Both case material and size impact weight. 42mm cases are lighter than 46mm cases.
