How to Write a Logline That Sells Your Script

Quick answer: a logline is a one-sentence summary of your script that tells a reader who the main character is, what they want, what stands in the way and what makes the story different. To write one, name a specific protagonist, the event that starts the story, the goal, the obstacle and the stakes, then cut it to about one or two sentences and look for the irony or hook that makes someone want to read the script.

A logline is often the first piece of your script anyone reads. It goes in query emails, contest entry forms, pitch meetings and script-hosting profiles. A reader decides in a few seconds whether to open the pages, and the logline is what they decide on. A development executive may also read it before deciding whether to request the script.

This guide shows how to write a logline step by step: the parts of a strong one, the length conventions, the formulas taught in well-known screenwriting books and a step-by-step rewrite of an example. It is part of the Movie Squirrel series on how to become a screenwriter. Because a logline is a compressed version of your story’s shape, it pairs closely with the guide to screenplay structure. All example loglines below are original examples written for this guide, not loglines from real films. It also touches on a few screenwriting concepts.

What a Logline Is

A logline is a short description of a story’s core premise and conflict, usually a single sentence. It is not a summary of the whole plot, and it does not reveal the ending. Its job is to show the setup, the central conflict and the promise of the story, the kind of movie a reader will get if they turn the page. It names the main story elements and narrative elements, such as character, conflict and stakes, and works as a dramatic teaser for the film.

Writers use loglines in a few places:

• Query letters and emails to managers, agents and producers.
• Contest and fellowship applications, many of which ask for a logline with the script.
• Pitches, where the logline is often the opening line.
• Their own development work, as a test of whether the idea is clear before drafting.

That last use is underrated. If you cannot state the story in one sentence, the script may not know what it is about yet. Anyone entering the screenplay market, whether pitching a producer weighing film financing or a story department sorting submissions, benefits from a clear logline.

The Core Parts of a Logline

Most logline advice comes back to the same handful of ingredients. Not every logline includes all of them, but strong ones usually make each part clear. Together, the conflict, goal and stakes are usually the center of the logline, and these narrative elements match what a reader looks for in the full script.

The Protagonist

Name the main character by a short, specific description rather than by name. “A burned-out paramedic” tells the reader more than “Dana.” A well-chosen adjective suggests the flaw or trait the story will test. Main character traits such as a flaw or a wish for character growth give the story something to test.

The Inciting Incident

This is the event that disrupts the character’s life and starts the story. In a logline it often appears as “when…” or “after…”: “When her ambulance is hijacked…” It is often a life-changing event that pushes the main character out of their routine.

The Goal

What does the character have to do? A concrete, visual goal, such as getting a witness to the courthouse by dawn, is easier to picture than an abstract one, such as finding herself. A clear goal set against the conflict is what drives the story.

The Antagonist or Obstacle

Who or what stands in the way? It can be a person, a group, nature, a system or the character’s own weakness. The more specific the opposing force, the clearer the conflict. This antagonistic force is what makes the goal hard to reach.

The Stakes

What happens if the character fails? Stakes give the reader a reason to care. They do not have to be the end of the world. Losing custody of a child or a family business closing can carry a whole film if they matter deeply to the character. The stakes often grow out of the life-changing event of the inciting incident, and the antagonistic force keeps pushing the character toward losing them.

Irony or Hook

The hook is what makes this story different from every other story in its genre. Often it is a form of irony: a contrast between the character and the situation, such as a pacifist forced to lead a rebellion or a wedding planner who is terrified of commitment. Irony gives a logline its spark. An emotional hook is what makes a reader care, whether the film is an action movie or an indie film. A hook can also come from a character twist or a world twist in the premise, and good hooks carry emotional energy that makes a reader curious.

How Long Should a Logline Be?

There is no official rule. By common convention, a logline is one sentence, sometimes two, and many teachers suggest keeping it to roughly 25 to 50 words. Contest and submission forms may also set their own character or word limits, so check the specific form. Professional writers often trim a logline until it carries only the essentials.

The practical test is how it sounds out loud. If you cannot say it in one breath to someone at a party, or it needs a pause to explain who someone is, it is probably too long.

Logline Formulas From Published Sources

Several screenwriting books offer templates. They are starting points, not rules.

Blake Snyder's Save the Cat

In Save the Cat!, Blake Snyder put the logline at the start of the writing process and argued that writers should nail it before writing the script. He described four elements of a good logline:

1. Irony: the logline should be ironic or contain an emotional hook.
2. A compelling mental picture: it should suggest a whole movie, a story with a clear beginning and end, in the reader’s mind.
3. Audience and cost: it should give a sense of who the movie is for and roughly what kind of budget it implies.
4. A killer title: the title and logline should work together, with the title saying what the story is.

Snyder also stressed describing the hero and the antagonist with adjectives that hint at who they are, and giving the hero a clear, primal goal that anyone can understand, such as survival, love or protecting family.

A Simple Fill-in Template

Many teachers and websites use a version of this pattern:

When [INCITING INCIDENT], a [SPECIFIC PROTAGONIST]
must [GOAL] before [STAKES], despite [OBSTACLE].

It is easy to fill in, but it can produce flat sentences. Use it to make sure every part is there, then rewrite until it reads like a story. Each slot in the template stands for one of the narrative elements.

The Question Test

Another useful check is whether the logline creates a dramatic question the script will answer: will she get the witness to court, will he win back the farm? If the logline does not suggest a question, the reader has nothing to wonder about.

How to Rewrite a Logline: A Worked Example

The examples below are original and were written for this guide. They show one logline improving through several drafts. They are not famous logline examples from real films.

Example Draft 1 (Too Vague)

A woman goes on a journey and learns about herself.

This could describe thousands of movies. There is no specific character, no event, no goal and no opposition.

Example Draft 2 (Specific but Flat)

A paramedic named Dana has to drive a witness across the city
while bad guys chase her.

Better. Now there is a character and a goal. But “bad guys” is generic, the stakes are missing and nothing feels unexpected.

Example Draft 3 (Parts in Place)

When her ambulance is hijacked by a wounded mob accountant,
a burned-out paramedic must keep him alive and get him to the
courthouse by dawn while his former employers hunt them both.

This has a protagonist, an inciting incident, a goal, a deadline and an antagonist. It is 32 words. The hijacking is the life-changing event that starts the night.

Example Draft 4 (With Irony)

A burned-out paramedic who has stopped caring whether her
patients live must keep a wounded mob accountant alive until
dawn, when his testimony can bring down the men who killed
her partner.

Now the hook is clear. The character’s flaw is exactly what the situation tests, and the stakes are personal. It is also clear what kind of movie this is: a contained, single-night thriller. Here the antagonistic force is the group of men who killed her partner, and the loss of her partner is a past life-changing event that makes the stakes personal.

Notice what the final draft leaves out. It does not explain the subplots, name every character or reveal the ending. A logline sells the premise, not the plot. It also leaves out the third act and any late character twist.

Loglines vs. Taglines vs. Synopses

These three get mixed up, but they serve different purposes.

• A logline describes the story: character, conflict and stakes, usually in one sentence. It is mainly for industry readers.
• A tagline is a marketing line on a poster or trailer meant to create a mood or a question, not to explain the plot. “In space no one can hear you scream,” the widely quoted tagline for Alien (1979), says nothing about the characters or the story, and that is the point.
• A synopsis is a longer summary, usually a paragraph to a page or two, that covers the main plot from beginning to end, often including the ending.

When a form asks for a logline, do not send a tagline. Industry readers want to know what happens, not how the poster will feel. A TV show logline, like a TV guide listing, sells the premise in a line.

Common Logline Mistakes

1. Using character names instead of descriptions. “Dana must save Rick” means nothing to a stranger.
2. Being vague about the goal. “Must face her demons” is not something a camera can film.
3. Leaving out the opposition. Without an obstacle there is no conflict.
4. Cramming in subplots. A logline that lists three storylines is a synopsis in disguise.
5. Asking a rhetorical question. “What if the person you trusted most was lying?” says little about the story.
6. Hype words. “Hilarious,” “heart-pounding” and “a story like no other” tell the reader you are selling, not describing.
7. Mismatched tone. A comedy logline that reads like a grim drama confuses the reader about genre.
8. Writing it last and in a rush. Many writers find that drafting the logline early, then revising it after each draft, keeps the script focused.

Ideas and short phrases are not protected by copyright, according to the U.S. Copyright Office, so a logline on its own does not protect your story. The written script itself is what copyright protects.

Testing and Using Your Logline

A logline only proves itself when someone else reads it. A few simple tests help before you send it anywhere.

Say it out loud to a friend who has not heard the idea, then ask them to tell it back to you. If they cannot name the main character, the goal and the problem, something is missing. If they ask “and then what happens?”, that is a good sign, because the logline has created a question.

Write ten versions. Changing the order of the parts, the adjective on the protagonist or the way the stakes are phrased often produces a much stronger line by the fourth or fifth try. Keep the versions side by side and pick the one that is clearest, not the cleverest.

Match the logline to the pages. If your logline promises a single-night thriller and the script spends 30 pages on backstory, the reader will feel misled. Revise the logline after each draft, and check that the script’s opening pages deliver what the logline sets up. Screenplay format applies to the pages, not to the logline itself.

Finally, present it cleanly. A logline sitting above a messy title page undercuts itself, so pair it with pages that follow the conventions in the guide to how to format a screenplay.

Frequently Asked Questions

How long should a logline be?

By common convention, one sentence, sometimes two, often around 25 to 50 words. If a contest or platform sets a limit, follow it.

Should a logline include the character's name?

Usually not. A short description, such as “a disgraced chess prodigy,” tells a stranger much more than a name.

Should a logline reveal the ending?

No. A logline sets up the premise and conflict. The synopsis or treatment is where you share the ending.

What is the difference between a logline and a premise?

The premise is the core idea, sometimes phrased as a “what if” question. The logline turns that idea into a story sentence with a character, a goal and an obstacle.

Can I write a logline for a TV pilot?

Yes. Pilot loglines usually describe the series engine, the situation that will generate episodes, as well as the pilot’s own story. A TV show logline works much like the short description in a TV guide.

When should I write my logline?

Many writers draft one before outlining to test the idea, then revise it after each draft so it matches the script.
