Recommended Wrist Rest Height
19 mm
Minimum
16 mm
Maximum
22 mm
Keep wrists neutral and use the rest mainly between typing bursts rather than constant pressure contact.
Match wrist rest height with chair, desk, and keyboard angle for consistent upper-limb posture.
Measure rest height from desk surface to top compression point under your forearm/wrist area.
We can build and embed a custom version of Wrist Rest Height Calculator for your brand and workflow.
Answers: how thick should a wrist rest be, wrist rest vs keyboard height, and a mm range to test at your desk.
Keyboard front + desk + posture + force adjustments, minimum 8 mm floor.
Min and max for gel compression and personal preference testing.
When to float hands vs rest between bursts — synced with form output.
Default: 20 mm keyboard front · 72 cm desk · neutral · medium force → 20 + (0) + (-2) + (1) = 19 mm recommended (16–22 mm).

| Factor | Condition | Adjustment | Rationale |
|---|---|---|---|
| Desk height | Over 75 cm | +2 mm | Higher surface often needs slightly thicker rest |
| Desk height | Under 68 cm | −1 mm | Lower desk — thinner rest to limit extension |
| Desk height | 68–75 cm | 0 mm | Typical seated desk band |
| Posture | Neutral | −2 mm | Support at/below front edge — avoid extension |
| Posture | Slight negative | −3 mm | Thinner rest encourages downward wrist angle |
| Posture | Flat | 0 mm | Level forearm-wrist line — no extra drop |
| Key force | Low / medium / high | 0 / +1 / +2 mm | Heavier typists benefit from slightly more support |
| Profile | Example output | Note |
|---|---|---|
| Low-profile (≈12 mm front) | 14 mm rec (flat, high force) | Often thinner rest or none |
| Standard (≈20 mm front) | 19 mm rec (neutral, medium) | Default calculator baseline |
| High-profile (≈28 mm front) | 27 mm rec (neutral, medium) | Thicker rest — still below keycap tops |
Wrist rests support the palm/heel of the hand — not the carpal tunnel area under the wrist crease. Height should keep the hand in line with the forearm, slightly below the keycap plane.
recommendedMm = max(8, round(keyboardFrontMm + deskAdjust + postureAdjust + forceAdjust))minMm = max(6, recommendedMm − 3) · maxMm = recommendedMm + 319 mm (16–22 mm) — Keep wrists neutral and use the rest mainly between typing bursts rather than constant pressure contact.
14 mm (11–17 mm) — thinnest practical band.
27 mm (24–30 mm).
19 mm — Target a slightly negative wrist angle and avoid resting pressure while actively typing.
17 mm (14–20 mm) — desk adjust −1 mm.
21 mm vs 19 mm neutral — 2 mm higher when flat.
24 mm (21–27 mm) — desk +2 mm, force +2 mm.
Calculated 6 mm raw → clamped to 8 mm minimum output.
