Frequently Asked Questions
How much of my life will I spend looking at screens?
Multiply your daily screen hours by your remaining years, then divide by 24 to convert to full days. At 7 hours a day over 55 remaining years, that is about 16 years of 24-hour days — a large share of your waking life. This calculator does the math for you.
How much screen time is average?
The average adult spends around 7 hours a day looking at screens across phones, computers, and TVs — more waking time than many people spend on anything except work and sleep. Heavy users routinely exceed 9–10 hours a day.
How is the "years of your life" figure calculated?
It totals your daily screen hours across your remaining years of life and expresses that as equivalent 24-hour days. It is a way to visualize cumulative time — you are not literally awake for all of it, so the calculator also shows the percentage of your waking hours it represents.
How much screen time is healthy?
Experts generally suggest limiting recreational (non-work) screen time to under 2 hours a day for adults, and much less for children. Quality matters too — active, intentional use is different from passive endless scrolling.
How do I reduce my screen time?
Set app timers, turn off non-essential notifications, keep your phone out of the bedroom, use grayscale mode, and schedule screen-free blocks. Tracking your usage — as this calculator helps you visualize — is often the wake-up call that drives change.
