How to choose a mouse that fits
A short guide to what matters when you pick a mouse, in the order we look at it.
Know your hand
Hand length and palm width decide which sizes feel natural. Scan your hand on a blank sheet of A4 to get both.
Scan my handKnow your grip
How your hand rests on the mouse changes which shapes suit it.
- Palm
- Your whole palm rests on the mouse.
- Claw
- Your palm touches the back and your fingers arch.
- Fingertip
- Only your fingertips control the mouse.



Palm thickness
Thick, medium or thin may change how tall a mouse should be. You can pick one after the scan; skip it and we do not adjust.
- Thick
- A full palm; the base of the thumb clearly bulges
- Medium
- A natural curve in the palm, between the two
- Thin
- A flatter palm; the tendons on the back of the hand show more
Match the size
Length and width matter most. We compare both with your hand.
Look at the shape
Some shells are symmetrical; others are shaped for one hand. Hump position, front width and side curve change how a mouse sits.
