Desk & Chair Height for 5'9" (175 cm)
At 5'9", a standard 29–30 inch desk is close to your ideal sitting height (about 27.9 in), but an inch either way still matters over a full workday. Here's how to fine-tune it.
Your numbers at 5'9"
| Measurement | Height from floor | What it means |
|---|---|---|
| Chair seat height | 17.9″ (45 cm) | Thighs level, feet flat |
| Sitting desk height | 27.9″ (71 cm) | Keyboard at relaxed elbow height |
| Standing desk height | 44.5″ (113 cm) | Keyboard at standing elbow height |
| Standing desk + walking pad | 46.7″ (119 cm) | Adds about 2.25 in for the deck |
| Top of screen, sitting | 48.9″ (124 cm) | At or slightly below eye level |
| Top of screen, standing | 65.6″ (167 cm) | At or slightly below eye level |
Assumes regular shoes (about 1 in). Barefoot, subtract about 1 in from every number. Estimates from average body proportions: long legs or a long torso can shift them by an inch or two. Fine-tune in our calculator.
What this means for your setup
Fine-tuning a standard desk
Your desk is slightly high for you: raise your chair a little and use a low footrest if your feet stop resting flat. See our footrest and keyboard tray guide.
Buying a standing desk
Most frames cover your range, roughly 27.9 in sitting to 44.5 in standing. If you plan to add a walking pad, make sure the desk reaches about 46.7 in. See our standing desk guide.
Raising your monitor
Your seated eye height is about 48.9 in from the floor. If the top of your screen sits lower than that, a monitor arm or a stand will bring it up.
