Find the Perfect Fit
The table below is an aid to help you determine what Perfit Mouse Optical size you will need. You should measure your hand size using a ruler and compare the result to determine the recommended size.
- Measure on the palm side of the hand, from the tip of the middle finger to the first wrist crease with your hand held flat
- Compare your measurement with the table below.
Note: If your hand measurement is between two sizes and you have a relatively thin hand, select the larger size. If you have a thick palm you should choose the smaller of the two.
