How long should you stand at a standing desk?
For anyone who bought the desk and then stopped raising it.
Most people who buy a sit-stand desk use it enthusiastically for about three weeks and then leave it at sitting height for a year. If that is you, the problem is almost never that you picked the wrong ratio. It is that nothing in your day tells you to raise it, and nothing tells you when to come back down.
Still, the ratio question gets asked first, so here it is.
The ratios, and how firm they are
Not very. These are conventions that have been repeated until they sound like findings:
- 30 minutes standing per hour. The most common single figure.
- 20-8-2. Twenty sitting, eight standing, two moving about. Popular in ergonomics writing and the most specific-sounding of the three, which is exactly why it is worth being suspicious of.
- 1:1 across the day. Half sitting, half standing. Simple; also a lot more standing than most people new to a standing desk will tolerate.
They disagree with each other by a wide margin, which tells you what you need to know: nobody has established a precise correct ratio, and the round numbers are round because they are memorable. Treat them as starting points rather than targets you are failing to hit.
The more useful framing, and the one the specific numbers are all groping toward, is this: the goal is to change position regularly, not to stand for a particular total. Standing rigidly for four hours is not the win condition. It is a second static posture, and a more tiring one.
What actually goes wrong
Three things, in roughly this order of frequency.
1. You forget to raise it. By far the most common. The desk is a piece of furniture; it does not ask for anything. If you are deep in something at 10am, you will surface at 1pm and the desk will still be where it was.
2. You forget to lower it. Less discussed and more punishing. Standing past the point of comfort is how people conclude that standing desks “hurt their feet” and go back to sitting permanently. The fix is not better shoes; it is coming down before you notice you want to.
3. You have no idea how much you actually stood. Almost everyone overestimates. A stretch that felt like an hour is frequently twenty minutes, and a day that felt like “I stood most of the afternoon” is often forty minutes total. Without a number you are guessing, and the guess flatters you.
Notice that none of the three is solved by choosing a better ratio.
A pacing that survives contact with a real week
If you want something concrete:
- Start with two stretches a day, 20 to 30 minutes each. Deliberately modest. The failure mode of standing desks is over-committing in week one and quitting in week four.
- Put them where they naturally fit. Mid-morning and mid-afternoon, or attached to something that already happens — the standing stretch that starts when your first call of the day starts is the one you will keep.
- Come down on a clock, not on a feeling. By the time standing feels bad you have been up too long. A fixed 20 or 30 minutes and then down again is more sustainable than “until I get tired”.
- Walk at the transitions. The two minutes between sitting and standing is where the actual movement is. Standing still and sitting still are more alike than either is to walking.
- Only then, adjust. If two stretches are easy after a fortnight, add a third before you lengthen the existing ones.
Standing is not a substitute for moving
This is the part that gets lost. A standing desk changes your posture; it does not get you across the room. If you replace “sitting for three hours” with “standing for three hours”, you have changed something real, but you have not added any walking to your day, and the advice about breaking up long static stretches applies to both.
Which is why a good sit-stand routine and a good get-up-and-move routine are two different things that both have to happen. Treating one as covering the other is the most common mistake in this area.
Knowing what you actually did
The honest answer to “how long should you stand” is much less useful than the answer to “how long did you stand yesterday”, because the second one you can act on.
Office Shrimp tracks standing stretches on the phone as a thing you start and end, and shows the day’s total. It reminds you to raise the desk on your own interval, and — the half people are usually more grateful for — tells you when the stretch is up so you come down before your feet make the decision for you. If you are on your feet, it holds its movement reminders back rather than telling you to get up while you are already up.
It also does the thing the ratios cannot: it shows you the real number at the end of the day, which is usually smaller than you thought and is the only figure worth adjusting against.

A boundary worth stating. None of the above is medical advice. If standing or sitting is causing you pain, that is a clinician’s question — and if you have an existing condition, the right pacing for you is not something a listicle or an app can work out.
