Screen Time FAQ
Everything you need to know about converting screen time into days, and what it means for your digital habits.

Screen time typically includes any time spent looking at a phone, tablet, computer, television, or gaming console. This covers social media, streaming, browsing, messaging, gaming, and work-related screen use, depending on how you choose to track it.
There’s no single universal limit, as it depends on age, occupation, and lifestyle. However, many digital wellbeing researchers suggest that recreational screen time beyond 2 hours a day for adults, outside of work requirements, may be worth reviewing if it’s displacing sleep, exercise, or in-person relationships.
Various studies estimate that many adults average between 4 and 7 hours of screen time per day. At an average of 5 hours a day, that works out to roughly 76 full days per year, or over 5 years across a typical adult lifetime.
Common strategies include setting app time limits, turning off non-essential notifications, designating screen-free times such as mealtimes or the hour before bed, and replacing habitual scrolling with an alternative activity like reading, walking, or a hobby.
