Measure your hand length and width and choose how you hold a mouse. The calculator suggests the mouse length and width that fit, the comfortable range and the shape to look for.
- Mouse length
- Mouse width
- Grip style
Measure from the crease at your wrist to the tip of your middle finger.
The right mouse is a share of your hand length. For a palm grip the mouse should be about 60% of your hand length, a little less for claw and less again for fingertip. A 19 cm hand suits a palm-grip mouse of about 118 mm or a fingertip mouse of about 99 mm.
