Daily Sitting Time Percentile Calculator
See how your daily sitting time compares with a relevant reference population.
Matthews et al., Sedentary Behavior in United States Adults
ACT24 previous-day recalls from 2,640 adults. Mean 9.5 hours/day (95% CI 9.4–9.7; SD 3.9), and 50% reported more than 9.5 hours/day.
What this calculator measures
See how your daily sitting time compares with a relevant reference population. The comparison uses the reference population and evidence identified on this page.
How to interpret your result
A percentile describes the approximate percentage of the stated reference population with a lower value. When a source supports only categories, medians, or averages, Humanlytic shows that broader comparison instead of inventing an exact percentile.
How this works
Evidence quality
Calculated from survey data
Method
Humanlytic compares daily sedentary time with the study’s documented midpoint: 50% of U.S. adults reported more than 9.5 hours on a given day. The paper does not provide enough quantiles for a complete percentile curve, so no exact tail percentile is fabricated.
Data source
Matthews et al. — Sedentary Behavior in United States Adults: Fall 2019
Limitations
The study reports mean sedentary time and that 50% exceeded 9.5 hours/day, but not a full percentile distribution. Humanlytic therefore reports only whether a value is below, around, or above that population midpoint threshold.
