Keyboard & Mouse Ergonomics
Keyboard and Mouse Position for Happy Wrists and Shoulders
Where you put your keyboard and mouse decides how your wrists, arms, and shoulders feel by 5pm. Here's how to position them for neutral, pain-free typing.
Your keyboard and mouse are where your hands live for eight hours a day, so small errors in their placement compound into real wrist, arm, and shoulder strain. The fixes are simple, mostly free, and worth getting right — your forearms will thank you by 5pm.
Why keyboard and mouse height matters
When your keyboard sits too high, your shoulders creep up toward your ears and stay there; too low, and your wrists bend back. Either way, muscles that should be relaxed hold tension all day, and that's what becomes the ache between your shoulder blades or the tightness in your forearms. Get the height right and those muscles get to switch off. The target: elbows around 90 degrees, forearms roughly parallel to the floor, shoulders relaxed down.
Neutral wrist and elbow positions
"Neutral" means your wrists stay flat and straight while you type — the same line as your forearms, not cocked up toward the screen or dropped down. Your elbows stay close to your sides rather than winging out. If you're breaking these, the usual culprit is desk or chair height, not your hands. Raising the chair (with a footrest if your feet leave the floor) often fixes both at once.
Choosing between trays, desks, and wrist supports
If your desk is fixed and too high, a keyboard tray brings the keyboard down to elbow height. If it's too low, raise the chair. A flat or slightly negative keyboard tilt keeps wrists neutral better than the little flip-out feet, which actually bend your wrists back — leave those down. Match the mouse to the keyboard height so your hand isn't traveling up or down to reach it.
Mouse placement and movement patterns
The mouse should live immediately beside the keyboard at the same height, so your elbow stays near your ribs instead of reaching forward or out to the side all day. That repeated little reach is a common, overlooked source of shoulder strain. If you use a number pad you rarely need, a compact keyboard lets the mouse sit closer — a small change that meaningfully reduces shoulder load.
Stretch ideas for overused wrists
Even a perfect setup benefits from movement. The wrist flexor stretch directly counters the gripping and flexing of typing, and a cross-body shoulder stretch eases the arms and shoulders. Do them little and often — a desk break timer makes that automatic. For the full workstation picture, see our ergonomic desk setup checklist and the guide to desk posture and tech neck.
The bottom line
Set the keyboard so your elbows fall to 90° and your wrists stay flat, keep the mouse right beside it, and reserve the wrist rest for pauses. Most problems trace back to the keyboard being too high or the mouse too far — fix those, add a few wrist and shoulder stretches, and the day-long arm strain quietly disappears.
Frequently asked questions
How high should my keyboard and mouse be?
At a height where your elbows sit around 90 degrees and your forearms are roughly parallel to the floor, with wrists flat. If your desk is too high, raise your chair and add a footrest.
Where should I place my mouse?
Right beside the keyboard at the same height, so you're not reaching forward or out to the side. Keeping it close stops the repeated shoulder and arm strain that comes from over-reaching.
Do wrist rests help ergonomics?
They can, if used to rest between bouts of typing rather than to prop your wrists up while typing. The goal is neutral, floating wrists during use and support during pauses.
