How to write a short film script

August 16, 2026 · The StoryProp team

A short film script is one idea taken to about ten pages, because a page of screenplay runs roughly a minute on screen and every one of those minutes gets paid for — the short film budgeting guide published by Filmustage estimates $700 to $1,500 per minute of finished runtime, which puts a ten-minute film somewhere between $7,000 and $15,000. That arithmetic is why the form rewards selection over ambition. A short film is not a small feature. It is a different instrument — closer to a poem than to a chapter, closer to a held breath than to a journey. The most common mistake in a first short script is compression: taking a story that wants ninety minutes and squeezing until nothing has room to breathe. The scripts that work do the opposite. They find an idea that is genuinely small — one pressure, one relationship, one decision — and then give it every second of the running time.

What follows is the craft specific to the short form: sizing an idea to the container, writing with constraints instead of against them, building toward a turn, and landing an ending that keeps sounding after the cut to black. The mechanics of the format itself — sluglines, action lines, dialogue on the page — are the same grammar features use, and if those are new to you, how screenplay format works covers them; this piece assumes them and concentrates on the ten minutes.

One idea, explored fully

The defining discipline of the short script is singularity. A feature can braid a main plot with subplots and let them comment on each other. A short holds exactly one dramatic question and has to answer it on screen. A useful test before you write a word: state what changes in one sentence. “A woman comes to empty her childhood house and decides what she can keep.” If your sentence needs an “and meanwhile,” you have a feature idea, or two short ideas sharing a bed.

Take an example this piece will keep returning to. Mara comes back to the house she grew up in to pack it for sale. Her brother Daniel was supposed to help; he calls to say he isn't coming. In a kitchen cupboard she finds a chipped cup she cannot place and cannot throw away. That is the whole film. One location, two voices, one object, one decision — and everything in it can escalate. The phone call can curdle. The packing can stall. The cup can become the argument the two of them have never managed to have.

Constraint is part of the writing

Feature writers talk about structure; short filmmakers talk about resources. Every element you type is something a real person will have to find, borrow, schedule, light, and feed. A second location means moving every piece of equipment and starting the day again. Every additional speaking role complicates the calendar. Night exteriors, rain, moving cars, crowds, animals, children, period costume — each is a genuine cost in time and favors, and time and favors are the currency short films are actually made of.

Those costs are published, and they are worth knowing at the keyboard. SAG-AFTRA's Short Project Agreement — the tier written for films budgeted at $50,000 or less and running 40 minutes or under — sets no fixed floor on the current sheet: for the year beginning 1 July 2026 the Short Project day rate is negotiable, with $256.60 the preferred minimum, and pension and health adds 21% on top, rising to 22% on 6 September 2026. One actor for one day is about $310, and about $313 after that date, before anybody eats. The line that surprises first-time writers is locations. The nearest thing to a published cost sheet at this end of the business is the line-by-line model from Tools for Film, and it is a twelve-day micro-budget feature rather than a short — but the proportions travel: on a $97,250 total, locations come to $9,000 against $3,200 for the entire cast, nearly three times as much.

The productive response is to treat constraint as a prompt rather than a cage. One location that transforms — a flat that empties out over the course of the film, a kitchen that goes from morning to dusk — reads as richness, not poverty. Two actors who want different things in the same room generate more tension than six who each get a line. Writing “INT. KITCHEN — DAY” and staying there is not a compromise; chamber pieces get made, and getting made is the point of writing a short script at all.

Minutes are the scarcest resource. The old rule of thumb — a page of screenplay runs about a minute of screen time — holds well enough for planning, which means a ten-page script is five or six scenes at most. The institutions agree on the container: Sundance's published submission rules define a short as anything under 50 minutes including credits, and the Cannes short film competition regulations cap entries at 15 minutes including credits. Ten pages walks through every door. What it leaves no room for is an establishing scene that only establishes, a character who exists to deliver information, or a subplot of any kind. Whatever the film does not strictly need, the short cannot afford.

Short film ideas that fit the form

Good short film ideas are moments, not premises. A feature runs on an engine that can generate complications for an hour and a half; a short runs on a single combustion — a confession, a refusal, a theft, a last time, a first time, a decision someone has put off for years. When you are hunting, look for endings you can already feel, then work backward to the situation that earns them.

Three situations at the right size: a locksmith is called out to open a door and realizes the flat is her ex's; two strangers discover they have been visiting the same grave, each believing they were the only one; a man rehearses a eulogy in his parked car and cannot get one true sentence into it. Each is a single situation with a live wire in it, each fits two or three actors and one location, and each implies its own ending.

The test of a short idea is whether it can end. Many appealing ideas are actually situations — an interesting place, an odd job, a striking image — and a situation, left alone, only restates itself. Ask what the pressure is, what the decision is, and what will be visibly different in the last shot than in the first. If the answer is nothing, the idea is an atmosphere, and atmospheres are ingredients rather than films.

Shaping the ten minutes

When someone asks how to write a 10 minute film, they are usually asking a structure question, and three acts scaled down to ten pages produce a wind-up toy. A more useful shape has four movements: establish, complicate, turn, resonate. The first page or two put a person with a want into a specific place. The pressure arrives early — by page three at the latest. The middle escalates in behavior, not in speeches. Somewhere around page seven or eight the film turns, and the last page belongs entirely to the resonance of that turn.

The turn deserves its own paragraph because it is the short form's signature effect. It is not necessarily a twist; a twist reorganizes plot, while the turn reorganizes meaning. It is the moment the audience re-sees what they have been watching. In the house-packing short, the turn is not a revelation about where the cup came from. It is the moment Mara understands she is not angry about the sale — she is angry that Daniel gets to grieve casually, by phone, while she has to do it object by object.

Notice what the film version of that moment cannot do. Prose can hand a reader the realization directly — a short story gets to spend a sentence inside Mara's head, and the form is built around that access. Film has no inside. The turn has to surface as visible behavior: she stops wrapping the cup mid-motion; she lets her brother's next call ring out; she says something small and lethal in a perfectly pleasant voice. Writing a short script is largely the craft of finding the outward action that carries an inward change.

Endings that resonate on page ten

In a feature, a weak ending damages a strong middle. In a short, the ending is close to the entire experience — it is what a viewer retains, and often the only part they can describe a week later. The last image is your argument, so end on it rather than after it. If the film asks whether Mara can let the house go, the final shot is the cup: wrapped and boxed, or left deliberately on the windowsill for the next family to puzzle over. Either image is an answer. A line of dialogue explaining the answer would un-answer it.

Two habits protect endings. First, cut the scene after the ending. Draft shorts habitually carry a coda the film does not need — a leaving-the-house scene after the real ending already happened at the cupboard. Find the moment the question is answered and stop within moments of it. Second, trust silence. The resonance of a short lives in the seconds a viewer spends alone with the last image, and every extra line spends those seconds for them.

The calling card, and what it says

Shorts are described as calling cards, and the description holds. The reading is competitive — Sundance's announced 2026 short film program was 54 films chosen from a record 11,480 submissions, representing 22 countries — and what carries a film through that kind of filter is not scale. A finished short demonstrates judgment: that you can choose an idea sized to your means, hold a tone, and land an ending. Those are the things that cannot be faked, and the things people who read and watch for a living notice first. A proof-of-concept made without its own reason to exist plays like an advertisement for an absent film. Make the short because the idea fits ten minutes, and the judgment on display will say more for you than the premise ever could.

Then treat the script as the production document it is. Read it aloud with a timer running, because dialogue that reads at a minute often plays at two. Cut it by a page and see whether anyone misses the page. Those are judgment calls, and they are the writing. What sits around them is mechanics, and mechanics can be handed off: StoryProp is AI screenwriting software that treats sluglines, action, and dialogue as real semantic elements, so you can point at one scene and rework it without disturbing the formatting around it, and export FDX or Fountain when the script goes to a production. What stays yours is the part that reads: one idea, a handful of resources, ten minutes, and an ending you believed in before you typed the first slugline.

Ten pages leave no room for a scene that only sets up another scene. StoryProp drafts in real screenplay format at your direction, scene by scene, and holds what you have already decided about the film, so a revision to page seven does not quietly rewrite page two — with FDX and Fountain export when the script goes to the shoot.
