There are many factors that come into play when sizing your mouse, such as shape and grip style, but we've focused on the size of your hand comparitive to the mouse itself.

Length: Measure your hand from the base of your palm to the top of your middle finger.

Width: Measure from the knuckle of your thumb to the edge of your palm.

Mouse Size Hand Length Hand Width
Small Up to 17cm Up to 8.5cm
Medium 17 to 19cm 8.5 to 9.5cm
Large 19cm and above 9.5cm and above

*These sizes should only be used as a guide, but we would love to hear your feedback on your own personal experience. All mouse sizes shown here at EG are based on this guide.
