How Long to Binge Every Simpsons Episode?

If you've ever wondered how long it would take to watch every single episode of The Simpsons, the answer might surprise you: roughly 12 days of continuous, non-stop viewing. That's 293 hours across 801 episodes as of December 2025.

The math is simple but staggering. With each episode averaging about 22 minutes (the standard sitcom runtime without commercials), you're looking at over 17,600 minutes of Springfield shenanigans. Stack them back-to-back and you'd need to stay glued to your screen for nearly two straight weeks.

The World's Longest Marathon

To put that in perspective, 12 days is longer than most people's vacation time. It's 288 hours—enough time to fly around the world twice, read War and Peace three times, or sleep for about 96 full sleep cycles.

And here's the kicker: The Simpsons isn't done yet. Fox renewed the show through 2029, which will bring the total to 858 episodes. By then, a complete binge will clock in at around 315 hours—over 13 days.

Why So Many Episodes?

The Simpsons has been on the air since 1989, making it the longest-running American sitcom and animated series in television history. Season 37 is currently airing, with no end in sight.

• The show has won 36 Emmy Awards
• It's been broadcast in over 100 countries
• The 800th episode aired on December 7, 2025
• Fox has committed to at least 858 episodes by 2029

The sheer volume of content is both a testament to the show's cultural impact and a daunting challenge for completionist viewers. Even watching three episodes a day, you'd need nearly nine months to finish the series.

Has Anyone Actually Done It?

Yes. In 2014, FXX aired every Simpsons episode in a 12-day marathon event called "Every Simpsons Ever." At the time, there were only 552 episodes, so the marathon ran for 288 hours straight. Fans dubbed it "The Longest Marathon in TV History."

Today, with 801 episodes, a similar marathon would need to run nearly two full weeks. Good luck staying awake for that.
