Welcome to the TV Series Duration Calculator

TV shows have been increasing in popularity for many years now, and that probably won't change for a while. Even if you haven't watched Avatar: The Last Airbender, Star Wars, The Wire, The Witcher, Breaking Bad, or Friends, your friends have probably been going on and on about them — so you know that they're addictive.

If you're up-to-date with your favorite series, you probably have the date the new season airs written on your calendar and can recall it at any given time of the day or night. Either way — once a TV series has become a significant part of our daily routine, we hardly realize how much time we spend thinking about it, let alone watching it.

This calculator lets you do the maths quickly. Simply insert:

  • Average episode duration (in minutes or hours).
  • Number of episodes per season.
  • Number of seasons the show is airing for.
  • Optionally, your daily watching time to find out how long it will take you to finish.

The tool will quickly return how much time you could be spending on your favorite show. It should come in very handy if you're just starting a series that premiered a few years back, or you want to rewatch your favorite childhood show.


FAQs

How do I calculate the duration of a TV series?

To calculate the duration of a TV series, be sure to know the following:

  • The number of episodes per season;
  • The number of seasons; and
  • The average length of each episode.

Multiply these values to find the duration of the TV series:

Total Duration = Episodes per Season × Number of Seasons × Episode Duration

If you want to be even more accurate, consider special episodes of greater length or count the episodes in each season individually.

How long would it take me to watch a TV series?

To calculate how long it would take you to watch an entire TV series, follow these easy steps:

  1. Calculate the duration of the series: multiply the average length of an episode by the number of episodes (episodes per season × number of seasons).
  2. Decide how many hours per day you want to watch.
  3. Divide the total duration (in hours) by your daily watching time.
  4. If you want a more relaxed estimate, convert days to weeks by dividing by 7.

How long would it take me to watch all of The Simpsons?

The Simpsons is one of the longest TV series currently airing on television. With 34 seasons and almost 22 episodes per season, the series counts approximately 740 episodes. Multiplying the number of episodes by the average length of one episode (22 minutes): 22 min × 740 = 16,280 min. This equals about 271 hours, or just above 11 days of uninterrupted watching!

Why are TV series episodes 22 minutes or 45 minutes long?

The reason behind the typical duration of 22 or 45 minutes lies in TV listing slots. Most sitcoms or animation shows receive half-hour slots, which — considering the additional time for a couple of ad breaks — allows for a 20 to 24-minute duration. The same holds for drama series: in this case, the allotted slot is one hour long, which, doubling the advertisement times, leaves space for 40 to 50-minute long episodes.

What units does this calculator use?

This calculator supports both metric-style decimal minutes and hours for episode duration. The results are displayed in minutes, hours, days, and weeks — giving you a complete picture of your binge-watching commitment. There are no monetary calculations in this tool since it purely measures time.
