Standing Desk Height Calculator

Use the calculator above to turn your height into the four measurements that actually determine a comfortable setup: standing desk height, seated desk height, chair seat height, and monitor position. Switch between metric and imperial, and the numbers update instantly.

How the numbers are calculated

#

The single most important rule for a standing desk is elbow height. When your forearms are roughly parallel to the floor and your elbows are bent between about 90° and 120°, your wrists stay straight and your shoulders relax — the neutral posture that OSHA’s Computer Workstations guidance describes as the goal for keyboard and mouse work. For a standing desk, the typing surface should sit right at that standing elbow height, which for most people falls near 61% of total height — the figure the calculator uses for the standing number.

The seated desk, chair, and monitor figures come from the same well-established anthropometric ratios (seated elbow height, popliteal/knee height for the chair, and standing eye height for the screen). They’re starting points calibrated to your stature, not one-size-fits-all averages — which is why a 160 cm and a 190 cm person should never be typing at the same desk height.

How to dial it in

#

1. Set the standing height first, then stand and type for a minute. Your wrists should be flat, not bent up or down.
2. Drop your shoulders. If you’re shrugging to reach the keyboard, the desk is too high; if you’re leaning down, it’s too low.
3. Position the monitor so the top of the screen is at or just below eye level and you look down about 15–20°. OSHA puts the preferred screen distance at roughly 20–40 inches (50–100 cm) — about arm’s length. A monitor arm makes it easy to keep that consistent between sitting and standing.
4. Alternate. The healthiest setting isn’t sitting or standing — it’s switching every 30–60 minutes.

The mistakes that make a standing desk hurt

#

Most standing-desk discomfort isn’t the desk — it’s a height that’s off by a few centimeters, compounded all day:

• Desk too high → shoulders creep up and wrists bend back. This is the most common error, because people set the surface to a comfortable-looking height rather than their measured elbow height.
• Monitor too low → you drop your chin to read, and your neck pays for it. Standing raises your eye line, so a screen that was fine seated is now too low.
• Standing flat on a hard floor → fatigue that gets blamed on standing itself. An anti-fatigue mat and occasional weight shifts fix most of it.
• All-or-nothing → going from all-sitting to all-standing overnight. Ramp up; your legs and feet need to adapt.

A note on shoes and desktops

#

If you usually wear shoes at your desk, add ~2–3 cm to the standing height. And remember the number is the typing surface height — if your desktop is thick or you use a keyboard tray, measure to where your hands actually rest, not the tabletop.

Once you know your target height, the next step is a desk that actually reaches it across its full range — see our standing desk picks, and keep the wiring clean with the desk cable management playbook.

Frequently asked questions

How do I calculate the right standing desk height?

Set the desk so your elbows rest at roughly 90–100 degrees with your forearms parallel to the floor and wrists straight while typing. For most people that lands near their standing elbow height — about 61% of total height. Enter your height above to get a personalized starting number.

What is the standing desk height for someone 5'9" (175 cm)?

Roughly 106–108 cm (about 42 inches) as a starting point, then adjust within a few centimeters so your elbows sit at 90–100 degrees. Taller or shorter users scale proportionally — use the calculator for your exact height.

Should my monitor move when I switch from sitting to standing?

Yes. The top of your screen should stay at or just below eye level in both positions, so a monitor arm (or raising the monitor when standing) keeps your neck neutral. The calculator shows your approximate standing eye level.

How often should I switch between sitting and standing?

There's no single perfect ratio, but alternating roughly every 30–60 minutes is a practical target — the best posture is your next one. Many people start with a 1:1 or 2:1 sit-to-stand rhythm and adjust to comfort. Movement and variation matter more than hitting an exact standing quota.

Is this calculator a substitute for proper ergonomic assessment?

No — it gives evidence-based starting heights from your stature. Fine-tune by comfort: relaxed shoulders, straight wrists, and a screen you look slightly down at. If you have pain or specific needs, consult an ergonomics professional.
