A screenplay is not literature; it is a blueprint for a film. So "how to write a screenplay" really means several smaller questions: how to find an idea that can carry 90 minutes, how to build a structure, and how to finish a first draft instead of stalling on page twenty. Here is a step-by-step route that works for features and short films alike.
Step 1. The idea and the logline
Film ideas rarely arrive complete; usually it is an image, a situation, or a "what if". To test whether an idea contains a film, compress it into a logline: one or two sentences describing the whole story.
The working formula is protagonist + goal + obstacle + stakes: who acts, what they want, what stands in the way, and what they lose if they fail. If one of the four is missing, the story is not ready yet.
Two examples:
- "A rural paramedic who is terrified of water must get a sick boy across a flooded river in a single night, because the bridge will be gone by morning and there is no other road to the hospital."
- "A fired subway dispatcher sneaks back into his station to prove the crash was not his fault, before the internal investigation closes the case for good."
Notice that each logline has a deadline. It is not mandatory, but a time limit adds tension instantly. For more breakdowns, see our logline examples.
A logline is also a self-check: if you cannot retell your story in two sentences, neither the audience nor a producer will understand what the film is about.
Step 2. The protagonist: want, need, and antagonist
A strong protagonist has two driving forces that do not coincide.
The want is the external, conscious goal: save the boy, get the job back. It fits in one sentence, and it moves the plot.
The need is what the protagonist actually requires but usually does not recognise: to learn to trust, to let go of guilt. The need drives the inner arc: invisible at the start, accepted or rejected at the end.
The most interesting films live where want and need collide: to get what they want, the protagonist must sacrifice something that matters.
The antagonist is not necessarily a villain but the force between the protagonist and the goal, with its own logic. The river in the first logline is an antagonist; so is the bureaucracy in the second. The more convincing the antagonist's case, the harder the choice and the stronger the drama.
Before you touch structure, write down: what the protagonist wants, what they need, what is in the way, and what they risk.
Step 3. Screenplay structure: three acts and turning points
Screenplay structure is not a formula but a way to distribute tension so the audience never tires or gets bored. The most common model is the three-act structure.
The three-act structure in pages
For a 90–110 page feature the landmarks look roughly like this (one formatted page runs about a minute of screen time):
- Act one (pages 1–25). We meet the protagonist in their ordinary life. Around page 10–12 comes the inciting incident that breaks the balance. The act ends with the first turning point: a decision there is no coming back from.
- Act two (pages 25–80). The protagonist acts, and every attempt makes things harder. Around page 50–55 comes the midpoint, often a false victory or false defeat that changes the rules and pushes the protagonist from reacting to attacking. The act ends with the second turning point, the lowest point, where all seems lost.
- Act three (pages 80–110). The climax is the final confrontation with the antagonist, where want and need finally meet. A short resolution shows how the world has changed.
Turning points are the moments when the story changes direction and there is no way back. If you cannot name two or three, the plot is probably moving in a straight line.
The eight-sequence approach, briefly
Act two is the longest and hardest. To keep it from sagging, many writers divide the film into eight sequences of 10 to 15 pages, each with its own mini-goal and mini-climax: not a different structure, just a finer grid over the same three acts.
Short films
A short film screenplay of 5 to 15 pages plays by different rules. There is no room for a long setup: the story starts as close to the inciting incident as possible, often with it. One protagonist, one goal, one key change. The three acts shrink to a handful of scenes, and the midpoint often coincides with the single turn. The best shorts are built around one strong image or one situation.
Step 4. Synopsis and scene outline
Now expand the logline and structure.
A synopsis is a prose retelling of the story in one to three pages, present tense, beginning to end, ending included. Not a teaser but the full story. It shows whether the plot holds before you write a single scene, and producers and competitions will ask for it later.
A scene outline (beat sheet) lists every scene in order, one or two lines each: where, who, what changes. For a feature that is usually 40 to 70 entries.
The most convenient tool is index cards. One scene, one card. Lay them out on a table or a corkboard and the structure becomes visible: here is act one, here is the midpoint, here is the hole between pages 40 and 50 where nothing happens. Cards are easy to reorder, discard, and add, and rewriting a card is far faster than rewriting a finished scene. The outline need not be perfect; it is enough to see the route and know what happens next.
Step 5. Writing the first draft
The main rule of a first draft: finish it. Not polish it, but get to "The End". A draft that stopped on page 40 cannot be improved; a bad but finished draft can.
The scene as a unit of conflict
Every scene is a small story with its own conflict: someone wants something, someone stands in the way, and at the end the situation has changed. If a scene changes nothing in the plot, the relationships, or what the audience knows, cut it and no one will notice.
A useful test: enter the scene as late as possible and leave as early as possible. Do not show the protagonist parking and saying hello; start when they are at the table and the conversation is getting awkward. End on the line after which everything is clear; skip the goodbyes.
Show, don't tell
A screenplay is what the audience sees and hears. "Marta misses her brother" is not a scene. Marta setting the table for two every evening and silently clearing the second plate is. Convey emotion through action, detail, and choices, not through explanations in description or dialogue.
Dialogue with subtext
People rarely say what they think. In good dialogue characters talk about the weather when the subject is divorce and argue about dishes when the subject is trust. Lines like "I'm angry at you because you betrayed me" ring false. Let characters hide, dodge, and lie, and the audience will read the truth. And every line must either move the scene or reveal the character, ideally both. Cut everything else.
A daily quota
A first draft of a feature can realistically be written in four to six weeks if you keep a rhythm. Set a quota of three to five pages a day and hit it regardless of mood; three pages a day is a feature in a month. Do not go back to rewrite yesterday's pages: flag what you dislike with a note and keep moving.
Step 6. Screenplay format
Industry format is the language you share with the director, producer, and actors: 12-point Courier, scene headings, action lines, centred character names, dialogue with fixed margins. A correctly formatted page runs about a minute of screen time, so format also lets you estimate running time. All the rules with examples are in our guide on how to format a screenplay, and modern editors apply the format automatically, so all that is left is to write.
Step 7. Rewriting
Screenplays are not written; they are rewritten. Put the first draft away for at least a week, then read it in one sitting as an audience member, fixing nothing. Note where it got boring, unclear, or unbelievable. Then use the tools that work:
- Reading aloud. Dialogue that looks fine on the page often cannot be spoken. Read it aloud and you will hear redundant words and unnatural phrasing immediately.
- A table read. Hand out the parts to a few people and listen to the script from the outside. It is the fastest way to see which scenes sag.
- Feedback. Give the script to two or three readers you trust. Do not ask "did you like it?" but "where were you bored?", "what was unclear?", "what did the protagonist want in act two?". If several people stumble in the same place, the problem is there.
- What to cut. Scenes that change nothing. Characters who duplicate another's function. Dialogue that explains what the audience has already seen. The first and last lines of scenes, which are most often unnecessary. A second draft is usually shorter than the first, and that is a good sign.
Save every draft as a named version: "Draft 1", "After table read", "Competition version". You will want to bring back a scene you cut three versions ago, and it is better to find it in a minute than rebuild it from memory.
Step 8. What next: pitching, competitions, producers
A finished screenplay will not sell itself. Prepare a package: logline, one-page synopsis, short character descriptions, and the script as a PDF. Submit to competitions and pitching sessions; even without winning you get coverage and contacts. Look for producers who work in your genre. And start the next screenplay: the second is always easier than the first.
Frequently asked questions
How many pages should a feature screenplay be?
Usually 90 to 120 pages in industry format; for a debut aim for 90 to 110. A page roughly equals a minute of screen time. A 140-page script from a first-time writer will almost certainly not be read to the end.
How long does it take to write a screenplay?
A first draft of a feature takes four weeks to three months at a steady rhythm. With idea development, outlining, and two or three rewrites, a realistic timeline is six months to a year. A short film takes a few weeks.
Do you need a screenwriting degree?
No. You need three things: many screenplays read, many pages written, and honest feedback. Courses and workshops speed things up and give you a community, but they do not replace practice.
Where should a beginner start?
With a short film of 5 to 10 pages. It lets you go through the whole cycle (logline, outline, draft, rewrite) in weeks rather than a year, and make your mistakes at a small scale. In parallel, read the screenplays of films you love: the scripts themselves, in format.
