Work out keyboard angle comfort instantly with clear inputs, formula shown and shareable results.
A positively tilted keyboard adds directly to wrist extension, and extension beyond about fifteen degrees raises carpal tunnel pressure sharply. The neutral solution is a flat or slightly negative tilt with the keyboard at or just below seated elbow height, which is why the flip-out feet on most keyboards should stay closed.
Net wrist angle
Net extension = observed wrist extension + keyboard tilt
Desk adjustment
Adjustment = seated elbow height - desk height; negative means the desk is too high
Preliminary estimate only. Individual display screen equipment assessment should be carried out by a competent assessor.
Net extension = observed wrist extension + keyboard tilt. A positively tilted keyboard adds directly to wrist extension, and extension beyond about fifteen degrees raises carpal tunnel pressure sharply.
Only as a place to rest between bursts of typing. Resting the wrist on a pad while typing anchors the hand and increases deviation, so it should support the heel of the palm during pauses instead.
