Desk Height Calculator + Setup Rules

Use this practical baseline to set desk and chair height quickly, then fine-tune based on your body and daily tasks. A good setup reduces wrist strain, neck tension, and lower-back fatigue—especially in compact workspaces where positioning errors stack up fast.

Quick baseline calculator

Starting desk height: roughly 0.27 × your height (cm). Treat this as a starting point, not a fixed rule.

How to fine-tune in 5 minutes

  1. Set chair height so feet are flat (or on a footrest).
  2. Adjust desk/keyboard so elbows are around 90° while typing.
  3. Keep wrists neutral (not bent upward).
  4. Set monitor so top edge is at or slightly below eye level.
  5. Pull screen close enough to avoid leaning forward.

Setup rules that matter most

  • Feet: flat and stable.
  • Knees: around 90–100°.
  • Shoulders: relaxed, not shrugged.
  • Head/neck: neutral, eyes naturally level with upper screen area.

Small-space adjustments that improve comfort

  • Use a shallower keyboard placement to avoid shoulder reach.
  • Raise monitor with a compact stand instead of stacking random items.
  • Choose a chair that tucks fully under your desk when not in use.
  • Manage cables so desk position changes don’t pull on devices.
