41mm

The case is surprisingly slim for how much protection it offers, and the clear back lets my phone's color show through without adding bulk. Fits my hand really well, and the buttons are still easy to press through the material.

I dropped my phone on concrete the second day and the case took it without a scratch, which is exactly why I bought it. The compact fit still lets me reach the screen edges easily, and it doesn't add any bulk to my pocket.

The 41mm size is perfect for my hand—it's compact but still gives me a solid grip. I've dropped my phone twice already and the case has held up without any scratches, which is exactly the reliable protection I was after.
