How to Use This Calculator
Enter your daily screen time for each device category (phone, computer, TV, gaming, tablet). The calculator totals everything and shows weekly and yearly projections plus what percentage of your waking hours you spend on screens.
Formula
Daily Total = Phone + Computer + TV + Gaming + Tablet hours
Weekly = Daily × 7
Yearly = Daily × 365
% of Waking Hours = Daily / 16 × 100
Weekly = Daily × 7
Yearly = Daily × 365
% of Waking Hours = Daily / 16 × 100
Example
Example: Phone 3.5h + Computer 4h + TV 2h + Gaming 0.5h + Tablet 0.5h = 10.5 hours/day. That's 3,832 hours/year (160 full days!) and 66% of waking hours.
Frequently Asked Questions
- Experts recommend limiting recreational screen time to 2 hours per day for adults. The average American spends over 7 hours per day on screens.
- This calculator tracks all screen time. While work-related screen time is necessary, excessive total screen time is associated with eye strain, poor sleep, and reduced physical activity.
- Set app timers, create phone-free zones (bedroom, dining table), use grayscale mode, and replace one screen activity with a non-screen hobby daily.
- Every 20 minutes, look at something 20 feet away for 20 seconds. This helps reduce digital eye strain during extended screen use.
