What This Calculator Estimates
The calculator divides your sitting window by the chosen interval, then multiplies breaks by break length. It is a practical schedule helper, not a medical risk score.
| Plan | Total break time in 8 hours |
|---|---|
| 5 minutes every 60 minutes | About 40 minutes |
| 3 minutes every 30 minutes | About 48 minutes |
| 10 minutes every 90 minutes | About 50 minutes |
Use a realistic interval. A small break that actually happens is usually more useful than an ambitious break plan that never starts.
