Most people who try to set up an ergonomic desk make the same mistake: they buy one “ergonomic” product and assume that’s enough. Ergonomics is a whole-system adjustment. This guide walks you through all 6 components in the right order — each step builds on the last.
Step 1: Set Your Chair Height First
Everything else is calibrated from your chair. Start here.
- Feet flat on the floor (or on a footrest)
- Thighs parallel to the floor, knees at 90–110°
- Lumbar support pressing into the natural curve of your lower back
- Armrests at elbow height, shoulders relaxed
Tip: Adjust with your shoes on — you’ll be wearing them while working.
Step 2: Set Your Desk Height
With your chair set, your elbows should rest at ~90° when your forearms are on the desk surface. Most standard desks (29–30″) work well for people 5’8″–6’0″. If you’re shorter, raise the chair and add a footrest. For standing desk users, the same 90° rule applies.
Step 3: Position Your Monitor
Monitors are almost always positioned too low. Fix this first:
- Height: Top of screen at or slightly below eye level (0–2 inches below)
- Distance: 20–28 inches from your eyes
- Tilt: 10–20° backward
- Position: Directly in front of you — not off to the side
Laptop users: use an external monitor or laptop stand to hit the right height, paired with an external keyboard.
Step 4: Set Up Your Keyboard
- At elbow height — same as your desk (confirmed in Step 2)
- Close to your body — keyboard near the desk edge, not pushed back
- Wrists straight and neutral while typing — not bent up or down
Step 5: Position Your Mouse
- Directly beside your keyboard — no reaching across the desk
- Same height as your keyboard
- Elbow close to your body when using it
If your keyboard has a numpad pushing the mouse too far right, consider a compact or tenkeyless keyboard.
Step 6: Check Your Lighting
- No bright light source directly behind your monitor (causes glare and eye strain)
- Windows should be to your side — not in front or behind the screen
- Monitor brightness should match your room brightness — not brighter
- Add a desk lamp for task lighting if overhead lighting is poor

Common Mistakes
- Monitor too low — neck forward flexion, tension headaches. Fix: raise monitor with arm or riser.
- Chair too high — feet dangle, thigh compression. Fix: lower chair, add footrest.
- Keyboard too far — shoulder strain. Fix: pull keyboard to desk edge.
- No lumbar support — lower back fatigue. Fix: adjust lumbar or add a cushion.
- Wrists on pad while typing — carpal tunnel compression. Fix: let wrists float while typing; rest only during breaks.
The Bottom Line
Set up your ergonomic desk in this order and the whole system works together:
- Chair height → feet flat, knees at 90°
- Desk height → elbows at 90°
- Monitor → top at/below eye level, 20–28″ away
- Keyboard → at elbow height, close to body, wrists neutral
- Mouse → beside keyboard, same height
- Lighting → from the side, no glare
