What hand size do I need for a vertical mouse?

Most vertical mice (Logitech MX Vertical, Anker Vertical) are designed for medium to large hands, 17 to 20cm hand length. If your hand is under 17cm, these mice will position your thumb in an awkward forward reach and reduce button control. Look for compact vertical mice specifically sized for smaller hands, or consider a trackball, which eliminates grip altogether.

Are trackball mice better than vertical mice for small hands?

Trackballs have one ergonomic advantage for small hands: the hand rests flat or in a neutral position without needing to grip a shaped body, so hand size matters less. A thumb-operated trackball (Logitech MX Ergo) positions the thumb actively, which can strain small hands. A finger-operated trackball (Kensington Slimblade, Kensington Expert) distributes the tracking motion across the fingers rather than concentrating it in the thumb.
