Seated desk height for someone 5 ft 10 in
Quick answer
Someone 5 ft 10 in tall wants a seated work surface about 28.7 in (73 cm), with the chair seat at 17.5 in (44 cm) and the top of the screen near 48.3 in (123 cm). A standard fixed desk is 29 in, so this body is 0.3 in below what a fixed desk gives you.
The stature multipliers behind this table are conventions, not published standards. Two people of the same height can differ by more than an inch in leg or torso length, which is exactly why ANSI/HFES 100 specifies adjustment ranges rather than single correct numbers.
| Dimension | Target | Usable band | Where it comes from |
|---|---|---|---|
| Work surface height | 28.7 in (73 cm) | 27.5 to 29.9 in | Height x 0.41 |
| Chair seat height | 17.5 in (44 cm) | 16.5 to 18.5 in | Height x 0.25 |
| Elbow height above seat | 10.1 in (26 cm) | Set armrests here | Height x 0.145 |
| Eye height, seated | 48.3 in (123 cm) | Top of screen at or below | Seat + height x 0.44 |
| Seat pan depth | 17.1 in (43 cm) | 2.5 in knee clearance | Height x 0.28 minus clearance |
| Thigh clearance under desk | 24 in (61 cm) | Minimum | Seat height plus thigh depth |
| Setup | Surface height | Result for this body |
|---|---|---|
| Fixed desk, 29 in | 29.0 in (74 cm) | Close enough to work with a small chair adjustment. |
| Adjustable desk at target | 28.7 in (73 cm) | Elbows land level with the surface, forearms parallel to the floor. |
| Keyboard tray under a 29 in desk | 26.5 in (67 cm) | A tray alone does not close the gap for this body. |

How this height is worked out
The seated surface target is your height multiplied by 0.41, which puts the work surface at about the level of your elbows when you sit upright with your upper arms hanging. For a 5 ft 10 in body that is 28.7 in. The point is not the number, it is the joint angle: the forearms should be roughly parallel to the floor with the elbows open to between 90 and 120 degrees, and the wrists straight rather than bent back over the front edge.
Everything else follows from the chair, not the desk. Set the seat height first so your feet are flat and your thighs are level, which for this body is about 17.5 in. Then bring the desk to your elbows. If the desk cannot come down far enough, raise the chair and put a footrest under your feet instead, because a dangling foot loads the back of the thigh and is a worse problem than a slightly high desk.
Why a single number is not the whole answer
The 0.41 multiplier is a convention. It assumes your limb proportions are average for your height, and plenty of people are not: a long torso with short legs and a short torso with long legs both occur at 5 ft 10 in, and they want different desk heights even though the tape measure says the same thing. That is why the band in the table above is 27.5 to 29.9 in rather than a single figure, and why the published standards describe ranges instead of targets.
The reliable test takes ten seconds and beats any formula. Sit back in the chair with your feet flat, let your arms hang, then bend your elbows to about a right angle. Where your fingers sit is where the keyboard should sit. If the desk surface is higher than that, you are holding your shoulders up all day, and that shows up as neck and upper back ache long before it shows up as anything you would call a wrist problem.
Questions people ask
What desk height is right for someone 5 ft 10 in?
About 28.7 in (73 cm) for seated work, with a usable band of 27.5 to 29.9 in. That is derived from elbow height rather than from any standard, so treat it as a starting point and confirm it by sitting down: forearms parallel to the floor, elbows open past a right angle, wrists straight and shoulders relaxed.
Is a standard 29 in desk too high for this height?
A standard fixed desk is 29 in, and the target for a 5 ft 10 in body is 28.7 in, a difference of 0.3 in. That is close enough that a chair adjustment covers it comfortably.
Should the desk be at elbow height or slightly below?
At or very slightly below. The forearms want to be parallel to the floor or sloping down a little, because a surface above elbow height forces the shoulders up to reach it. A surface a touch below lets the arms drop naturally and keeps the wrists straight, which is the position the standards describe as neutral.
Does a keyboard tray change the desk height I need?
Yes, and it is the cheapest fix for a desk that cannot go low enough. A tray typically sits 2 to 3 in below the surface, so a 29 in desk with a tray puts the keyboard near 26.5 in. For this body that still does not land in the right range, so the desk height itself is the thing to change.
