| One size fits all desks are so non-ergonomic it's not funny. The trouble with your question is that user height is a poor proxy for what desk height should be because how much of your height is in your legs vs torso also affects it. Anyway, here's another data point: I'm 5'4". I keep my desk at 24" when sitting, 41" when standing. I use an external keyboard plus a riser for my laptop to avoid having to look downwards at it. The riser is adjustable but currently set at ~14", IIRC. The next ergonomic adjustment I want to make is to swap out my crappy desk chair for one with adjustable arms so I can sit closer to the desk and type with my elbows at a right angle instead of arms outstretched. I get shoulder tension these days, but am pretty sure that's just good old fashioned stress. No keyboard/mouse related RSI since I switched to mousing lefty 10 years ago. Though my back and neck are less happy after a full day of meetings, which mean sitting with the laptop at a much taller conference table with no riser. I do get wrist and neck pain these days related to looking down at my phone and contorting my fingers to hold it securely while attempting to use it one-handed, because despite being the smallest on the market it's too large for my small-person hands. What I said about mousing lefty? I switched because of RSI that I'm pretty sure was related to a much too tall desk. At almost 36", my options were to sit with toes dangling above the ground, type with fingers at chin height, or perch on the very edge of my chair all day with no lumbar support. All sorts of bad things were happening to my body. Switching the mouse saved my wrists for a few months. Leaving the job, getting a desk at a more sane height, a keyboard tray (one without a 6 inch deep wrist rest), and a keyboard with lighter resistance saved my career. Ergonomics matter. Even a desk job can cause permanent physical injury. And our phones aren't helping either. Adjust your chair height before you adjust your desk height. When your feet rest comfortably on the floor with your knees at a right angle while sitting back and upright in your chair, hold your elbows at your side at a right angle. Your desk height should be about an inch below the bottom surface of your lower arm. Or if you use a keyboard tray, the surface of the tray should be at that height. Then raise your monitor until you're looking at it straight ahead, not up or down. This applies whether you're sitting or standing. Most people these days are bending their necks forward to see their laptops. Those trendy silver Mac laptop risers are about a foot too short for most people. You probably need 12-24" of height added. Any external monitors may need raising too. And of course, plan to use an external keyboard and mouse. |
If, at 5'10, I am experiencing problems related to desk height, I can only imagine problems are worse for those shorter. I wonder if there is a correlation between height and these kind of problems. Standard desk height seems to be designed for someone who is 6'2.
I was considering adding a keyboard tray, but I'm thinking that I mostly use my desk for a keyboard and mouse, I might as well optimize the desk for that use rather than having an add-on for that purpose.
