What Is a Logline?
Quick answer: A logline is a one-sentence summary of a story: protagonist, goal, obstacle, stakes. Borrowed from film, it is the sharpest pitch tool fiction has.
A logline is a story compressed into one sentence: a specific protagonist, what they want, what stands in the way, and what happens if they fail. Film industry in origin, it now serves novelists and short story writers as the fastest possible pitch. A working template: when an inciting event upends their world, a flawed protagonist must pursue a concrete goal against a formidable obstacle, or face defined stakes.
The form looks trivial and is not. Writing a true logline forces you to know, in public, whose story this is and what drives it. Plenty of writers discover mid-sentence that their novel has three protagonists, no goal, and stakes they cannot name, which is painful information best received before drafting chapter twenty.
The anatomy of a working logline
Four load-bearing parts. The protagonist, described by role and flaw rather than name, since names carry no information: a disgraced harbour pilot, an ageing con artist, a timid archivist. The goal, concrete enough to film: not find herself but recover the ship's log before the inquest. The obstacle, ideally personified or at least specific. And the stakes, the consequence that makes failure matter.
Two qualities separate good from generic: irony and specificity. Irony is the built-in friction, a claustrophobic astronaut, a detective who must exonerate the man who ruined him. Specificity is nouns doing the work of adjectives. A dangerous secret says nothing; her testimony in a sealed murder trial says everything.
Where the form comes from
The name is Hollywood shorthand: studio readers once logged incoming scripts in ledgers with a single descriptive line, and the line that sold the script in a corridor became a craft of its own. Screenwriting culture then formalised it, because film pitches happen fast and money follows clarity. Publishing borrowed the tool as agents and editors began asking for one-line hooks in queries and meetings.
The migration made sense because the underlying question is medium-neutral: can this story's engine be stated? Jaws in one line, a small-town police chief afraid of water must stop a killer shark tourists will not believe in, was pitchable before a frame existed. Novels with engines that clean, whatever their literary register, are simply easier to sell at every stage.
Loglines built from stories you know
Recast familiar books and the anatomy shows. Pride and Prejudice: a quick-witted young woman who trusts her own judgement must untangle her prejudice against a proud stranger, or lose the one man who matches her. The Martian: a stranded astronaut presumed dead must farm a lifeless planet with scraps, or starve before rescue can reach him. Each names the person, the pressure, and the price.
Notice what the good ones omit: theme, backstory, subplots, and any evaluation of the work. The logline is not the story's meaning; it is the story's motor. A quiet literary novel still has one: in one line, a grieving translator returns to her mother's village to sell the house and must decide what she owes a language she abandoned.
Using a logline as a drafting tool
Write the logline before or during the first draft and pin it where you work. It becomes a compass: scenes that serve neither the goal nor the obstacle announce themselves, and revision decisions get easier because the sentence defines what the book is. If the draft outgrows the logline, rewrite the logline consciously rather than drifting; either movement is fine, but know which is happening.
It also earns its keep at submission time. Query letters open stronger with the engine visible, contest entries with tight word limits benefit from a writer who can compress, and when someone at a party asks what your book is about, the difference between ninety seconds of hedging and one clean sentence is the difference people remember.
Where loglines go wrong
The universal failure is vagueness with gravitas: a man must confront his past and discover what family truly means. No person, no goal, no obstacle, no stakes, just theme wearing a trench coat. Next: the two-sentence cheat that smuggles in backstory, then a world where, then a chosen one. If it needs two sentences, the engine is not yet found.
Also common: naming characters (wasted words), listing plot instead of pressure, and mistaking the logline for advertising, which produces empty superlatives. Test yours on someone who has not read the book. If they ask a question that starts with but why, the logline is missing its causality, and possibly the book is too.
What poets can take from this
- Build the sentence from role, flaw, goal, obstacle, and stakes; leave names and themes out.
- Hunt for the irony: the person for whom this exact problem is hardest makes the strongest logline.
- Replace every abstraction with a noun you could photograph.
- Pin the logline above your desk while drafting and audit scenes against it during revision.
- If your logline needs two sentences, keep compressing; the second sentence is usually hiding the missing engine.
Try it yourself
Write loglines for three stories you know well, then one for your work-in-progress using the same template: when X happens, a flawed Y must Z, or W. Read all four aloud to someone and ask which story they would pick up. If yours loses, find the missing irony and rewrite it.
Questions
How long should a logline be?
One sentence, ideally 25 to 40 words. Shorter is possible for high-concept stories; longer usually means backstory or subplot has crept in. The discipline of the single sentence is most of the tool's value.
Is a logline the same as a tagline?
No. A tagline is advertising copy, often cryptic and mood-driven, like a poster slogan. A logline is informational: it states the protagonist, goal, obstacle, and stakes so a professional can judge the story's engine at a glance.
Do short stories need loglines?
They are rarely requested, but writing one is still useful. If your 1,500-word story cannot be stated as a person under specific pressure, the draft may be a sketch rather than a story, and the logline exposes that early.
