A new week means new letters and new ergonomic tips for using your mouse. This week we’re focusing on L‑O‑S.
L — Lift Your Wrist
When you’re using your mouse, your wrist should not be resting on the work surface. I should be able to slide a piece of paper between your wrist and the desk.
Use your shoulder to guide the mouse in a smooth, controlled movement instead of planting your wrist and pivoting from that point.
If you need to rest your hand, rotate your wrist/hand 90 degrees and rest on your small finger, with your palm facing left if you mouse right‑handed. When you’re ready to resume, simply rotate your hand back onto the mouse.
O — Over the Mouse Buttons
Your fingers should rest over the mouse buttons—not behind them—and your wrist should not sit behind the mouse.
Aim for a natural “C” shape in your hand while you’re palming the mouse.
S — Standard Mouse
A “standard” mouse typically refers to a bilateral (ambidextrous) mouse that can be used with either the left or right hand.
Check whether it fits comfortably in your palm:
If you’re squeezing the sides with your thumb and small finger, the mouse may be too small.
If your fingers are stretched wide, the mouse may be too large.
If your mouse is too big or too small, I’m happy to recommend options that may work better for your hand size and work style.
