How do I measure my hand?

When purchasing an ergonomic mouse, it is very important to select a mouse that fits the size of your hand. A mouse that is too small or too large often achieves the opposite effect, symptoms may even worsen. 

You measure the hand length from the transition of your wrist to the palm, to the tip of your middle finger. Hand width refers to the width of the palm at the level of the thumb crease.
