The Logline Formula: How to Pitch Your Story in One Sentence
A great logline is the difference between a script that gets read and one that gets passed on. Here is the formula working development executives use — and the eight tests every logline must pass.
You have 12 seconds. That's roughly how long a development executive will spend on the logline of your query email before deciding whether to read further. If your logline doesn't earn that read, the script never matters. Here's how working professionals build loglines that get attention.
The Core Formula
The most reliable logline structure has six elements:
- An adjective describing the protagonist (not their name — their relevant trait)
- The protagonist's role or job
- The inciting incident (what disrupts their world)
- The protagonist's goal
- The antagonist or central obstacle
- The stakes (what happens if they fail)
Example: "When a paranoid hacker stumbles onto evidence that the government has cloned his dead daughter, he must break into the most secure facility in the country before the program is moved overseas — or lose her forever."
Notice every element is present: adjective ("paranoid"), role ("hacker"), inciting incident ("stumbles onto evidence"), goal ("break into the facility"), obstacle (security/government), stakes ("lose her forever").
The Eight Tests
Run your logline through these tests before sending it anywhere:
1. The Irony Test. Does the protagonist's situation feel ironic or paradoxical? "A blind detective tracking a sniper" is more compelling than "a detective tracking a sniper." Irony creates immediate hook.
2. The Visual Test. Can you picture the movie from the logline alone? If not, you're being too abstract. Replace concept words with concrete imagery. "A man comes to terms with his past" → "A grief-numb plumber returns to the lake where his brother drowned thirty years ago."
3. The Specificity Test. Are there at least two specific details that make this story this story and not any other? Generic loglines die. "A young woman fights for justice" is dead. "A 19-year-old courtroom interpreter realizes the Spanish-speaking defendant is actually innocent — but she'll lose her job and her green card if she says so" is alive.
4. The Stakes Test. Are the stakes specific and personal? "Or the world will end" is generic. "Or his daughter will marry the man who killed her mother" is personal. Personal stakes outperform world-ending stakes for dramatic engagement, even in big-canvas films.
5. The Comparable Test. Could you describe this with "It's X meets Y"? If yes, you have a marketing handle. "Die Hard on a bus" sold Speed. "Toy Story with feelings" sold a thousand pitches. This isn't the logline — but if you can't generate a comparable, the logline is too unfocused.
6. The 25-Word Test. Can you say it in 25 words or fewer? Most working loglines are 20-30 words. Anything longer signals the writer doesn't yet know what their story is about.
7. The Strangers Test. Read the logline aloud to someone who doesn't write. Do they ask a follow-up question? If yes, you've earned interest. If they say "huh, ok" you haven't.
8. The Genre Test. Does the logline make the genre obvious? "A grieving widow searches for her missing daughter" could be drama, thriller, or supernatural horror. Strong loglines signal genre through word choice — "stalks" vs "searches for" vs "investigates" all imply different genres.
Common Pitfalls
Naming characters. Almost never useful in a logline. The exception: real or famous people ("When Lincoln…", "When Mozart…"). Otherwise, "Sarah" tells the reader nothing.
Hiding the hook. Some writers bury the most interesting beat ("…and oh by the way, she has 24 hours to live") at the end. Lead with it. The hook should land in the first half of the sentence.
Vagueness about ending. The logline shouldn't spoil the climax — but it should imply that there is one. "Will she succeed?" is weak. The way the goal and obstacle are framed should imply the dramatic question.
Iterate, Don't Polish
Most loglines don't work on the first draft. Working writers will produce 20-50 versions of a logline before settling on one. Each version is a tiny experiment: what if I lead with the antagonist? What if I make the stakes smaller and more personal? What if I emphasize the irony? Don't spend an hour perfecting one logline — spend an hour generating ten and pick the best one.
A great logline isn't just a marketing tool. It's a diagnostic test of whether you actually understand your story. If you can't write one in 25 words, the script probably doesn't know what it's about either.
