What the Sitting Time and Sedentary Pattern Calculator calculates
Calculate the share of waking time spent sitting and the number of opportunities created by a user-selected movement reminder interval.
This is a sitting-time audit, not an individualized disease-risk score. It keeps daily time allocation and user-selected reminder intervals separate from medical risk assessment.
How to use the Sitting Time and Sedentary Pattern Calculator
- Estimate total waking time.
- Add sitting across work, transport, meals, and leisure.
- Choose a reminder interval if useful.
- Use the percentage as a time audit only.
Continue with the Calories Burned Calculator. Estimate a named activity separately.
Formula, variables and calculation order
sitting share = sitting hours / waking hours x 100; opportunities = sitting duration / interval.
Inputs are validated and normalized before calculation. Full precision is retained until the displayed result is rounded.

Worked example and boundary check
Worked example
Nine sitting hours in a 16-hour waking day is 56.25%.
Boundary check
Two people with the same sitting time can have different activity patterns and health contexts.
How to interpret the result
Use the result to identify where time is allocated. Follow current physical-activity guidance and individualized advice rather than treating the percentage as a diagnosis.
- Self-reported sitting time can be inaccurate.
- Does not measure moderate-to-vigorous activity or cardiorespiratory fitness.
- Does not calculate disease probability.
- Movement reminders are user-selected.

Frequently asked questions
Is 50% sitting a disease risk score?
No. It is only a time share.
Does exercise cancel sitting?
The calculator does not make that claim.
Should sleep be included?
No; use waking hours.
Are reminder intervals prescribed?
No. They are planning inputs.
