A life in running time
Films compress time. A two-hour story can cover a weekend, a lifetime or a century, and we accept it without thinking. Turn that around and your own life becomes a very long film: every two hours you live is one feature’s worth of running time. Someone in their mid thirties has already lived through more than 150,000 films’ worth of time, enough to watch a different film every night for over 400 years.
The strip above does the opposite. It squeezes your life so far into one feature, a frame for each year, and shows how much screen time each year would get. The answer, a few minutes a year, is a reminder of how much any single film leaves out.
How we calculate it
Your life in films is the hours you have lived divided by the film length you choose. Films watched are your monthly number times the months since your tenth birthday, and the time spent is that number times the film length. Frames assume real-time playback at 24 frames per second, the standard for cinema.
| Age | Two-hour films lived | Screen time per year, in a 2 hour film of your life |
|---|---|---|
| 20 | 87,658 | 6 minutes |
| 30 | 131,487 | 4 minutes |
| 50 | 219,146 | 2.4 minutes |
| 80 | 350,633 | 1.5 minutes |
Worked example. Someone born on 12 April 1990 has lived 13,350 days by 30 October 2026, which is 160,200 two-hour films. Watching three films a month since their tenth birthday adds up to about 954 films, 1,908 hours or 79.5 days of viewing. In a two-hour film of their life, each year would get about 3.3 minutes of screen time.
The longest films ever made
Some experimental films run for days, and there have been works designed to play for years, but even these are tiny next to a life. The real-time film of a 36-year-old’s life would hold more than 27 billion frames, as many as about 160,000 ordinary features put together.
Questions people ask
How long is an average film?
Most feature films run between 90 minutes and two and a half hours, and big releases have grown longer in recent years. We use two hours as the standard length, with options for a 90 minute film and a three hour epic.
How do you estimate the films I have watched?
We multiply the number of films you watch a month by the months since your tenth birthday, a rough start for watching whole films. Change the number to match your habits; it includes films at home as well as in cinemas.
What does the film of my life show?
It imagines your life so far squeezed into a single film of the length you choose. Each frame on the strip is one year, and the numbers underneath show how many minutes of screen time each year would get.
