Correct typing posture puts the keyboard at lap height with elbows at right angles and wrists straight

Standard desk keyboards sit too high, forcing upward wrist extension and hunched shoulders — both RSI risk factors. Correct posture places the keyboard at lap height (a lap desk helps) so elbows rest naturally at right angles and wrists stay straight. Seat height should let the feet touch the floor with knees at a right angle, the backrest set so the legs are at a right angle to the body, and the shoulders relaxed rather than hunched. A posture-corrective brace can help retrain the habit of dropped shoulders while the new posture becomes automatic.

Examples

Move the keyboard to a lap desk. Check: are elbows at 90 degrees? Are wrists straight (not flexed)? Are shoulders relaxed? Feet flat with knees at a right angle?

Assessment

Check your current typing posture against the article’s criteria (keyboard height, elbow angle, wrist angle, shoulders, feet/knees). Identify which you fail and the physical adjustment that corrects each.
