Selecting the right mouse size for PC gamers or regular users is essential. If a computer mouse is too large or too small, it would cause your palm to flex unnecessarely. This will reduce your reaction time in video games. In other cases, the wrong mouse size will cause you to use your wrist and the elbow in a non-ergonomic way, increasing your chances of getting a carpal tunnel.

How to select the right mouse size?

Though there isn't such thing as one-size-fits-all, you can use the below guide to correctly select the correct mouse size for your palm.

Measure Your Palm Size

  1. Measure your palm size. Take a ruler and measure your palm from the crease at the base of your thumb, all the way up to your middle finger (which is the longest one).

Compare Your Palm Size with a Gaming Mouse Size Chart

Whichever palm size cm or inch measurement number you get, you will now compare that to the computer mouse size chart below.

7-1/2" to 8-1/4"19 cm to 21 cmLarge
8-1/4" and above21 cm or greaterExtra Large

Shop for the Right Mouse Size

Once you determine your size, head on over to your favorite web site and chose the correct mouse size. Here is an example. Say, my favorite mouse is the BenQ Zowie EC2 and my palm length is 20 cm. This means that my size is medium.

When looking at the mouse versions, select medium (see screenshot below)
