What Is a Desk Timer?
A desk timer is a simple sit stand reminder for people who work at a standing desk. Instead of sitting frozen in one position for hours, you set a sit interval and a stand interval, and the timer loops between them all day. Each time an interval ends it chimes so you know to change position — raise the desk and stand, or lower it and sit. It takes the guesswork and willpower out of moving regularly, so switching posture becomes automatic rather than something you forget.
How Often Should You Sit and Stand?
There is no single perfect number, but common guidance is to alternate roughly every 30 to 60 minutes rather than staying in one position for the whole day. Many people find a rhythm of sitting for 45 minutes and standing for 15 works well, while others prefer an even 30 / 30 split. The most important thing is simply that you move regularly and change position often — long stretches of either sitting or standing are what you want to avoid. Start with intervals that feel comfortable and adjust as your body adapts.
Sit Stand Reminder for Standing Desks
This desk timer works as a standing desk reminder that runs continuously in the background. Pick a preset or type your own sit and stand minutes, press start, and it counts down the current interval. When the interval ends, the timer chimes, flashes, and flips to the next posture automatically — no need to restart it. The current posture (Sit or Stand), the countdown, and a progress bar all update live, and a "Switches today" counter tracks how many times you have changed position, so you can see how well you are keeping up the sit stand habit.
How to Use the Desk Timer
- Choose a preset like 45 / 15, or enter custom sit and stand minutes
- Press Start (or tap the spacebar) to begin the first sit interval
- When the chime sounds, change position — stand up or sit down as the phase shows
- The timer alternates posture on its own and keeps looping through the day
- Watch the "Switches today" count climb as you alternate posture
- Use Pause to take a break and Reset to start the cycle over
Standing Desk Tips
- Alternate posture rather than standing all day — too much standing is as tiring as too much sitting
- Set your screen to eye level and keep your elbows near a 90 degree angle whether you sit or stand
- Wear supportive shoes or add an anti-fatigue mat for your standing intervals
- Use each switch as a cue to move regularly — stretch, walk, or grab some water
- Change position before you feel stiff, not after; the timer is there so you do not have to rely on memory
- Adjust your sit and stand minutes until the rhythm feels natural for your body
