One of the most important aspects to consider when choosing a mouse is finding the right size that best fits your hand and grip style to ensure best performance and endurance.

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, then use the chart below to help you pick.

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


All mouse sizes shown here at EG are based on this guide.
