There is no single number of minutes that everyone should stand at a desk. Use the desk to change position during the day, and choose a pattern that fits your work and your circumstances. A timer can remind you to check in; it does not need to set a standing quota.
Start with the short answer
Do not treat a fixed sitting-to-standing ratio as a requirement. The useful habit is to notice when you have stayed in one position for a long stretch and decide whether to sit, stand, or take a short walk. A height-adjustable desk makes those position choices possible at the workstation.
The U.S. Occupational Safety and Health Administration’s computer-workstation guidance recommends changing working position frequently and standing or walking periodically. It describes ways to vary posture; it does not prescribe one standing-minute target for every person.
Change position with your work
Consider which tasks are practical at each height. A call or a short reading task may be an easy point to stand. Detailed work may be easier for you while seated. You can also step away from the desk entirely. Let your task and comfort guide the choice instead of trying to reach a daily standing total.
If you are new to an adjustable desk, make the first few changes easy to reverse. Keep your chair available and adjust the desk when the current position stops fitting the work. The aim is a workable routine, not the longest possible standing interval.

Check both desk heights
When you change height, look at the whole workstation. Can you reach the keyboard and mouse without stretching? Is the screen in a position you can view comfortably? At seated height, does the chair fit under the desk? At standing height, is there space to move without bumping equipment or pulling a cable tight?
Set up each height for your own equipment rather than copying a photograph or another person’s measurements. If you share a workstation, save or note the positions that work for each user. Compare current desk models if you need to check a model’s published height range.
Use reminders as prompts
A reminder can help you notice a long period in one position. When it appears, choose what makes sense: adjust the desk, sit down, walk briefly, or keep working and check again later. You can change the interval as your tasks change. The reminder is a prompt to decide, not a measure of success.
Our standing desk timer is a simple way to create that prompt. It does not prescribe a medical or ergonomic schedule. If you prefer to use your calendar or phone, the same decision process applies.
Adjust the plan to your needs
If a position causes discomfort, change it rather than trying to finish a target interval. If you have a medical condition, injury, pregnancy-related need, or a workplace accommodation, ask a qualified professional who knows your situation for individual guidance. The desk is a tool for changing height; it cannot determine the right amount of sitting or standing for you.
