Should a Left-Handed Person Use a Mouse With Their Left or Right Hand?

I’m right-handed and have used a mouse with my left hand for decades, especially when I need my right hand on the number pad or keyboard. It took roughly a couple of weeks to feel normal. You don’t necessarily have to swap the buttons either—you can learn to click with the fingers that feel natural.

There’s no required hand, and no mouse police are coming after you. Put it wherever it feels most comfortable. Most people simply adapt to whichever side their mouse is on.

Many mice are symmetrical, including the Magic Mouse, so they work on either side. In your computer’s Mouse settings, you can swap the primary and secondary buttons if that makes left-handed use feel more natural. Some mice are shaped specifically for the right hand, though, so those can be less comfortable on the left.

Using a mouse with the opposite hand is surprisingly easy to learn. I had to do it after injuring my dominant hand, and after about an hour it already felt much less awkward. Give your left hand a little practice before deciding it feels wrong.

You can also switch between hands to reduce fatigue. Some people use a trackpad, trackball, or a dedicated left-handed mouse instead. The best choice is simply the setup that feels comfortable and lets you work efficiently.
