How to Write a Sitcom: The Crucial Rules of The Game

How to Write a Sitcom: The Crucial Rules of The Game

It feels more important than ever to have a good laugh. And what better way to poke fun at the state of everything, or to find comfort, than with a sitcom? In this article we will plunge the depths of television, new and old, to give you a helping hand on how to write a sitcom script.

In such a ubiquitous genre, it’s often easy to lose sight of the rules and structures that have underpinned it for decades.

Using the hilarious work and teachings of some the best loved and well-known sitcoms out there,  we will offer pointers based on…

  • Defining the Genre
  • The Situation and Where to Start
  • The Cast of Characters
  • Forms of Sitcoms
  • Styles of Comedy
  • The Story Structure of a Sitcom
  • Inspiring Sitcom Ideas
  • How to Actually Write a Sitcom
  • The Importance of Defying Genre


Defining the Genre

So, what is a situational comedy? As the sitcom cliché goes, Webster’s dictionary defines ‘sitcom’ as:

‘a radio or television comedy series that involves a continuing cast of characters in a succession of episodes’ 

So a sitcom is simply a comedy in a situation. Frequently, this incorporates an ensemble cast of characters, who rarely change and rarely develop. The Simpsons is a sitcom which best exemplifies this lack of change as even after 30 years, the central characters are still the same age, in the same house, in the same town and even in the same clothes.

The situation is the place to start when writing a sitcom. The location and the cast of characters is vital to fuelling the comedy.

So, the ‘precinct’ or primary setting. This will be the starting point for the controlling idea of the show. When it comes to precincts there are three typical types of locations in which a sitcom can be situated.

  • The workplace
  • A home
  • A combination of the two


1. Workplace

Brooklyn Nine Nine uses a literal precinct in the form of the 99th Police Precinct. This is classed as a workplace situation comedy and features police officers in their various roles.

Other examples of workplace sitcoms include the TV studio in 30 Rock, the bars in It’s Always Sunny in Philadelphia and Cheers, the basement filled with nerds in The IT Crowd, the various political buildings and offices in Veep and The Thick of it and the offices in The Office and Parks and Recreation.

The concept of the workplace could also be less literal and include schools, universities and colleges, as in Bad Education and CommunityThe casts are therefore work colleagues or a work ‘family’.

To create an example, a sitcom could be set in a pizzeria, which is a place of work that would allow for a central cast of pizza chefs, owners, and waiters. But it could also feature recurring characters such as customers and delivery drivers.

2. Home

The home precinct is demonstrated in the aforementioned eternal sitcom The Simpsons, and in a number of other shows based around where people live.

These types of sitcoms include Friends, New Girl, SeinfeldModern FamilyWhat We Do In The Shadows and Spaced.

The primary location of each of these shows is a place where people live. Therefore, the casts consist of biological families or makeshift families formed of roommates or friends.

3. Multiple Precincts

The precinct is not always the only location and almost all shows include a number of bases for the characters to interact in, both in private and public.

  • Frasier includes the radio station and Frasier’s apartment as the two main bases but also frequently features a coffee shop.
  • Friends also centres around two neighbouring apartments and a coffee shop.
  • The school is the meeting place of the main characters in The Inbetweeners, but the show itself rarely centres within the school. Each episode focuses more on the characters being put into a new situation such as a theme park trip, night out or work experience.

It is rare that a sitcom only centres on one place. But it is vital for your own sitcom writing experience that the characters have a location where they can all meet. There, they can link up to go on a variety of antics.

However, a precinct doesn’t make it a sitcom. So far, all we have is a part of the situation. Unless you have comedic characters you’ve just written something more akin to a soap opera.

Funny People

A sitcom will not succeed unless it has characters who are funny. Funny can’t be the characters primary defintion though. The comedy has to come from somewhere intrinsically tied to who that character is.

When writing comedic characters, Judd Apatow often starts by reading self-help books, which allow him to think psychologically about his characters and build them from flaws and insecurities. This is a good example of how even comedic characters need depth.


Comedic Conflict

A basis of contradictory personalities and conflict is integral to every sitcom and to comedy in general. It is the first thing you should be considering when creating your characters in your sitcom.

To continue the earlier pizzeria example, it is important to create a makeshift family that all contradict each other. This may mean ensuring that one pizza chef is an Italian pizza purist, while another is an advocate of hot dog stuffed crusts, for example.


Frasier’s Ensemble

Fraiser Ensemble - Write a Sitcom

Using the cast of main characters in Frasier, it is clear to see that the creator thought psychologically about how to create innate conflict within the show’s cast.

  • Frasier himself is pompous, uptight and arrogant. An often competitive snob.
  • Frasier’s brother, Niles, is even more pompous and extremely uptight. The two brothers have a relationship based on competition to be the most successful brother. They also have opposing opinions and experiences eg. they went to different Ivy League Schools, they follow different psychiatric practices (Niles – Jungien, Frasier – Freudian).
  • Their father, Martin Crane, is the polar opposite to both of them but equally flawed, he is down to earth, interested in sports and steaks. He’s an everyman cop who is sarcastic and grumpy, but also emotionally detached and overly masculine, a stark contrast to his flamboyant sons.
  • Their live-in physical therapist/housekeeper, Daphne Moon, is kooky and believes in the supernatural, in direct contradiction to the two realist psychiatrist brothers.
  • Frasier’s radio producer, Roz Doyle, is a sarcastic, distinctly lowbrow and laidback compared to Niles and Frasier.

Therefore, as demonstrated by Frasier, it is crucial to have an ensemble cast with conflict built in to their very personalities.

The humour within Frasier comes from distinctions in personalities and differences in reactions to the situations that they find themselves in within each episode.


Different Forms of Sitcoms

Another important consideration to take into account when writing a sitcom is what form it will take. This will determine how the script will be written. Forms of sitcom include:


  • These are the simplest to write and follow dramatic writing conventions, as seen in Atlanta, New Girl, Gavin and Stacey.
  • Many shows use the single-camera form as an opportunity to create filmic episodes, giving the writer more scope to incorporate homages to other films and genres as seen in Community and Spaced.
  • The misleadingly named single-camera form usually uses more than one camera, but is shot without an audience.


  • These are often studio shows, shot in front of a live audience.
  • A consideration when writing is to leave spaces between jokes to allow for audience laughter.
  • Examples include: Friends, Frasier, The Big Bang Theory, The IT Crowd.


  • Similarly to single-camera, the animated sitcom allows for more creativity. For example, the use of surrealist jokes. After all, anything that can be created can be drawn.
  • Examples include: The Simpsons, Rick and Morty, Family Guy, BoJack Horseman.

Comedic Genres

There are many different comedic genres within comedy. Sitcoms often use a combination of styles and genres within them.

Watching and studying shows like those listed below will give you a good understanding of the potential breadth of genre within the crafting of a sitcom:

It’s important always to link the genre of your sitcom to your core values and intensions. These different comedic genres can have different functions. When misapplied or inappropriate their strength can feel undermined.

  • For example, The Office is about the minutiae of office life and the ego of the central character desperately trying to impress the omnipresent documentary crew. So a mockumentary format is perfect for this idea.
  • Whilst Spaced is about a group of aimless young adults saturated in popular culture. So to have it spoof and homage other films and genres makes perfect sense.


The Sitcom Story Structure

Sitcom story structure can be viewed similarly to the scriptwriting of any television show or film,  just condensed to a 22-30 minute script. When writing a sitcom the three-act structure can be applied as with every other genre of film or TV. This isn’t a strict rule but a helpful guide to follow.

Friends Season 1 Episode 5: The One with the East German Laundry Detergent demonstrates sitcom story structure well as it has three separate plots that all rapidly go through the three-act structure. It demonstrates how sitcoms both use the traditional film three-act structure but also have unique elements to their form as well.


First Act:

The friends are all gathered in the coffee shop. During the first act, they split up into pairs, creating three separate plots with two main characters in each.

A Plot: Ross and Rachel agree to meet and do laundry. Ross is nervous when he convinces himself that it is a date and wants it to go well. Rachel wants to do her own laundry to feel independent.

B Plot: Chandler wants to break up with his girlfriend, Janice. Phoebe wants to break up with her boyfriend, Tony.

C Plot: Joey wants to take his ex-girlfriend, Angela, on a date. So, he convinces Angela to go on a double date. Angela and her new boyfriend will go on a double date with Joey and Monica. However, Joey tells Monica that Bob is actually Angela’s brother, so Monica thinks she’s being set up with Bob.

Second Act:

All three subplots go through mild, comedic obstacles to achieve their goals, which were established in the first act.

A Plot: Ross and Rachel go to the laundrette. Ross defends Rachel’s washing machine from being taken by a ‘horrible woman’. Ross proceeds to teach her to do laundry. Rachel’s laundry doesn’t go well and everything turns pink.

B Plot: Phoebe easily breaks up with her boyfriend while Chandler is unable to break up with Janice. Chandler breaks the news to Janice and she reacts negatively.

C Plot: Joey continues to conceal the motives behind the double date. He plants the seeds for Bob to break up with Angela by highlighting Angela’s unappealing traits while he acts as a wingman for Monica. Monica and Angela go to the bathroom together and discuss Bob.

Third Act:

A Plot: Rachel stands up to the horrible woman proving her independence and Ross and Rachel briefly kiss. Ross then bumps his head on a washing machine door. During the End Tag, Rachel is icing Ross’ head.

B Plot: Phoebe intervenes in Chandler’s break up and Janice leaves happily. During the End Tag, Chandler runs through the streets celebrating his newfound freedom.

C Plot: Joey confesses to Monica that Bob and Angela aren’t siblings and the two agree to break the couple up. During the End Tag, Joey and Monica return from their date, overjoyed at having “ripped that couple apart”.

Everyone is basically in the same position as they were in when the episode started. They have gone through minor changes but are ultimately all still sat in the coffee shop together. The story has gone in a circle.


Other Examples and Structures

Dan Harmon, creator of Community and Rick and Morty handily adapted the 3-act structure into a story circle. The situation is allowed to change over the course of the episode but ultimately the characters are unchanged and in relatively the same position.

Harmon’s story circle is partially based on the “hero’s journey” and blueprints a successful structure for a sitcom.

  1. A character is in their comfort zone or regular situation (the precinct),
  2. But they want or need something else,
  3. They go into an unfamiliar situation or cross a threshold,
  4. The character adapts to the situation while facing trials and obstacles,
  5. Finding what they wanted, whether they like it or not,
  6. But the new situation “kicks their ass” and forces them to pay the price,
  7. Then they return to their familiar situation (the precinct),
  8. The events of the episode have changed them. In sitcom, this is rarely drastic.

Sitcoms are only 22-30 minutes long and thus the story structure is compressed and the story is almost on fast forward.


Write What You Know – But Make it Funny

One of the most common pieces of advice that people seem to tell you when writing is to write what you know. This is also true in sitcom, but as always, it doesn’t mean you can only write about yourself.

Take funny situations that happen to you and put your characters in the same situation, adapt the story of your life. If you meet someone that makes you laugh – write a similar character to them in to your medieval sitcom.


How to Actually Write A Sitcom Script

In terms of how to write a screenplay, the writing process of a sitcom script is similar to any other script. However, there are a few ways in which a sitcom script may vary. Consider the following elements of a sitcom script:

  • The Cold Open – This is an opportunity to include a joke which doesn’t play into the rest of the episode as a comedic hook to draw in a new audience.
  • The End Tag – Very similar to the cold open but at the end of the episode. Often it is a payoff to a small set-up from earlier in the episode. But it can also be an entirely original joke involving one or two characters (Troy and Abed often serve this purpose in Community).
  • Use of Flashbacks/Cutaways – Family Guy, 30 Rock and most mockumentaries frequently use flashbacks and cutaways for quick punchlines and gags.
  • Callbacks and Running Jokes – Arrested Development is a particularly excellent series for having jokes that pop up in different iterations throughout the series. It’s a kind of language that show itself will create and repeatedly use throughout.
  • Fast Paced Scenes – Scenes in sitcoms are rarely long, 1-2 pages per scene or set-up is fairly standard as it keeps the pace moving quickly and you can move on to the next joke or comedic setup quickly.

Re-Draft to Make It Funnier

Once you’ve completed your script, workshop it with people. Read it through aloud and see which bits are funny and which bits need work. Then, re-write, re-read, re-workshop your script.

This process will have developed it into something that, at the very least, you and your workshop find funny. If it makes you laugh, chances are it’ll make a few other people laugh.

Perhaps more than most genres, comedy is hard to get right without finding out if it works with an audience. This is even more relevant in a sitcom. So sharing your work with others and seeing how it plays to a room (however big or small that room may be) is a vital step in the process.


And Finally… Don’t forget to Defy Genre

When writing a sitcom, remember to innovate and create a genre hybrid. Combining elements of different genres and forms can create interesting and exciting new ideas.

  • What We Do In The Shadows, for example, combines a house-share, a mockumentary and a world in which supernatural creatures exist.
  • Peep Show takes a flat share and gives the main characters internal monologues.
  • Community takes a number of different genres and uses them throughout the series to create different innovative episodes within the sitcom genre.

Innovation makes the sitcom and your script stand out. This guide has given you the outline of what a sitcom is, how it works and how to write one.

It’s also important to know that as with everything else, these rules can and sometimes should be broken. If you want to write a sitcom about a pizzeria then do it. If you want to stray further from the norms and set this pizzeria in a medieval kingdom, that is your prerogative.

Innovation is important and so is enjoying what you’re writing. So write what you know, and write what you like. If your enthusiasm for the idea jumps off the page, then it will be of interest to like-minded people.

Sitcoms are there to make us laugh, comfort us and re-unite us every night with characters we’ve grown to know. It’s vital that in a genre with these intentions, these elements are baked into to the writing.

  1. I live in the UK, where sitcoms are different to those in the US. The word that springs to mind when I think of successful UK sitcoms is ‘trapped’. The characters must be trapped in a situation out of which there is very little means of escape. This means that the characters themselves mustn’t be funny or happy-go-lucky, though they can deliver knock-out one-liners from unfunny situations. Characters must take the situation they are in with a great deal of seriousness, and are looking of ways to get out – but always unsuccessfully. This is the main element of comedy in a UK sitcom. There must be real characters, with faults, good points, failures and ambition. who are not afraid to expose their emotional side in many scenes that get humour out of unfunny situations.

    There was, for instance, a UK sitcom (‘Only Fools and Horses’) where the main thrust of one episode was the one of the main characters having a miscarriage. I doubt if this would be allowed in an American sitcom, but it made for scenes that were handled tenderly, emotionally and sympathetically while still retaining a frisson of comedy. It was a triumph, and garnered many plaudits from the viewing public.

    May I say that my favourite American sitcom was M.A.S.H., which was shown on British TV to great acclaim. It fulfilled everything a British audience appreciates in a sitcom. The characters were trapped in a military hospital in Korea, they dealt with death and severe injuries which could have been played down but weren’t, and yet it was funny. Here in the UK there was no laughter track in the sitcom, which made it more emotionally satisfying, yet funny at the same time (I’ve seen episodes of M.A.S.H. with a laughter track), and this, to me at least, made the sitcom less funny.

  2. Its really helpful & informative…
    Kindly describe the sequence of writing dialogues along with scences and act

  3. I can’t believe it took me so long to watch Rick and Morty. I absolutely love this show. Did you guys like the most recent season as much as the first couple?

  4. Really helpful that you used actual examples of sitcoms to illustrate and reinforce your points.
    It’s surprising how many “tutorials” in screenwriting don’t do this very basic yet really fundamental “thing.”
    Would love to know how much character exposition needs to be revealed in a sitcom pilot and what are the tools to do this without it being clunky and boring.

    Thanks – really helpful springboard.
