Typing Posture and Ergonomics: How to Avoid Injury and Type Better

Your chair should be adjusted so your feet are flat on the floor (or on a footrest) and your thighs are parallel to the ground. Your lower back should be supported by the chair back — do not hunch forward.

The monitor should be at arm's length and eye level, or very slightly below. Looking up at a screen strains your neck; looking sharply down compresses your cervical spine. The top of the monitor should be at or just below your eye level.

Your desk height should allow your elbows to be at a roughly 90-degree angle when your hands are on the keyboard. If your desk is too high, raise your chair and use a footrest. If it is too low, consider a keyboard tray or a desk riser.

The most common ergonomic mistake is resting your wrists on the desk while typing. This compresses the carpal tunnel and restricts blood flow to your fingers. Your wrists should float — hovering just above the keyboard surface, never pressing down.

A wrist rest is useful for breaks between typing bursts, not for typing itself. Use it to rest your wrists when your hands are idle, then lift them when you begin typing again.

The keyboard should be flat or slightly negative-tilted (back of keyboard lower than front). Most keyboards have legs on the back that tilt them toward you — these legs are ergonomically incorrect for touch typing. Keep the keyboard flat or use the negative tilt if your keyboard supports it.

Strike keys with the pads of your fingertips, not the fingernails or the flat of your finger. Keep your fingers gently curved, as if you are holding a small ball.

Use light keystrokes. Most modern keyboards require only a few grams of force to register a key. Hammering keys wastes energy, creates noise, and causes fatigue over long sessions.

Avoid reaching with your pinky finger for shift, backspace, or control. If these modifier keys require uncomfortable stretching, consider keyboard shortcuts that use more natural hand positions.

The 20-20-20 rule for eyes: every 20 minutes, look at something 20 feet away for 20 seconds. The same principle applies to hands — every 20–30 minutes, stretch your fingers, rotate your wrists, and shake out any tension.

Warning signs of repetitive strain injury include tingling in fingers or hands, pain in the forearm or wrist during typing, and weakness in grip. If you notice these symptoms, reduce your typing load and see a doctor before they worsen.

Ergonomic keyboards — split keyboards, curved keyboards, or vertical mice — can significantly reduce strain for heavy users. They have a learning curve, but many users find they cannot return to flat keyboards after adapting.
