What Is a Screenplay? A Complete Beginner's Guide

What a screenplay actually is

A screenplay is 90 to 120 pages of formatted text describing what an audience will see and hear, written in the present tense, in the order it happens. Every scene is labelled with where and when it takes place, every line of speech is attached to a named character, and almost nothing is described that a camera could not record.

It has two jobs at once. It is a plan for a production — the first assistant director breaks it into shooting days, the production designer reads it for sets, the script supervisor uses it to track continuity. And it is a sales document, read by producers and executives who are deciding whether to spend money on it. Those two audiences are the reason the format is as rigid as it is: the format is how a stranger can find out how long the film is, how expensive it looks, and who is on screen in any given scene, at a glance.

The unit of measurement is the page, and one page of standard-formatted screenplay runs close to one minute of screen time. That calibration is why a page count is treated as a running time, and it is unique to this form. Nobody estimates a novel's reading time from its page count, and nobody budgets a play from it either.

What a screenplay is not is the film. It is a proposal, and it will be answered by other people with cameras, money and their own ideas. The script is the document that gets a hundred people into the same imagined film; after that, it is rewritten, cut, shot out of order and reassembled. The screenplay is the map, and the map is not the trip.

The six core elements of a screenplay

Every page of every screenplay is built from the same six elements. Here is a complete scene — the smallest unit of a screenplay — using all six, in standard layout:

INT. KITCHEN - 5:40 A.M.

A bare bulb. DANA, 44, in a wet fleece, fills a thermos
without turning on the light.

                    OWEN (O.S.)
          You're early.

                    DANA
          (not looking up)
          The boat's late.

She sets the thermos down. The wall clock reads 5:41 and
has read 5:41 for two years.

                                                      CUT TO:

Scene heading (slugline)

Opens every scene and answers three questions: interior or exterior, where, and when. INT. KITCHEN - 5:40 A.M. is a complete scene heading.

Action (description)

What the camera can see and hear, in present tense. Everything that is not dialogue and not a heading. A blank line separates action from dialogue.

Character cue

The speaker's name in capitals, indented, on its own line above the dialogue. Extensions go in parentheses: (O.S.) for off-screen, (V.O.) for voice-over, (CONT'D) when a character speaks again after an interruption.

Parenthetical

A short direction in parentheses under the character name, used only when the line would be misread without it. (not looking up) earns its space; (angry) and (beat) rarely do.

Dialogue

The spoken words, set in a narrow column under the name. In standard layout the block is about 3.5 inches wide, roughly a third of the page.

Transition

A right-aligned capitalised instruction such as CUT TO:, DISSOLVE TO:, FADE IN: or FADE OUT. Modern spec scripts use only the fade at each end of the script, because every cut is already a cut.

That is the whole vocabulary. The craft is in what you choose to put in the action lines and the dialogue, not in the formatting, which is fixed so that it stops being a decision.

Spec script vs shooting script

These are two different documents written for two different stages, and confusing them marks you as an outsider before anyone reads a page.

A spec script exists to get you work or to be sold. That is why it leaves out scene numbers, angles and cuts: those are decisions for a director, and a spec that pre-empts them looks like a writer who does not know whose job what is. A shooting script is a controlled document — once a draft is locked, revisions are issued on coloured pages that are inserted into everyone's copy, historically blue, then pink, yellow, green, goldenrod, buff, salmon, cherry. The colour order is the version number.

The practical consequence is that when a script sells or is optioned, writing the production draft is usually a separate, paid job — not a creative rewrite but a rewrite for production reality: a location becomes unavailable, an actor is cast older than the character, a stunt costs more than it is worth. Writing your spec for the version of the film in your head and letting a production draft be somebody else's problem is the correct instinct.

Why one page equals one minute

The page-per-minute relationship is the reason the format has survived. Standard layout is US Letter paper, 12 point Courier at ten pitch, one-inch margins on three sides and an inch and a half on the left for binding, which produces roughly 55 lines to the page. That density was calibrated so a page of screenplay takes about a minute of screen time, and the calibration is why a 110-page script is understood as a two-hour film.

It breaks in both directions, and knowing how is more useful than knowing the rule. Dialogue-heavy pages with overlapping banter play faster than a minute. A page containing one action line — a fight, a chase, a collapse — plays slower, sometimes much slower. A page of a montage could be fifteen seconds or two minutes depending on how it is shot. So a 120-page action script is not necessarily 120 minutes, and writers working in action deliberately write short pages to make room.

What the page count communicates reliably is professionalism and market shape. Comedy specs run 90 to 105 pages. Contained thrillers and horror often land between 90 and 100. Dramas run 100 to 120. Epics and established writers run longer. A debut spec over 120 pages is a self-inflicted wound: readers make a judgement in the first ten pages, and a script that announces two and a half hours before anyone reads a line starts with a mark against it. The same applies in the other direction — a 70-page feature reads as a sketch or a pilot, not a film.

This is also why writers trim by rewriting rather than by shrinking the font. A schedule is built from page counts; roughly a few pages a day is a normal shooting rate for a feature, so page count becomes shooting days, and shooting days become money. When a producer says your script is long, they are saying it is expensive.

What a screenplay is not

Not a novel

You cannot describe what a character thinks, remembers or secretly feels. Interiority has to be turned into something photographable: not 'she realises he is lying', but 'she stops mid-sentence. Looks at his hands.' The writing carries the emotion in what people do, and the reader infers the interior. This is the hardest adjustment for prose writers, and it is not optional.

Not a transcript

Screen dialogue is not how people talk. Real speech is full of false starts, repetitions and pleasantries, and a faithful transcript is unactable. Written dialogue is compressed until every line is doing work or is cut, which is why the second draft of any scene is usually half the length of the first. The related misconception is that a screenplay records the finished film: mostly it does not. Published screenplays issued after a film's release are usually assembled from what was shot, and they differ from the shooting draft, sometimes enormously.

Not a stage play, and not a production plan

A play is usually language in a fixed space, and it can hold twenty pages of talk in one room. A screenplay moves freely — sixty locations, a car chase, a crowd, a century — and a script that is twenty pages of people talking in a kitchen is a play with sluglines. Conversely, a screenplay is not the place to solve production problems: do not write that a set is too expensive, that effects will be added later, or which lens to use. Write the story and leave the money to the people who hold it.

From spec to screen: how a script moves through the industry

The path is well established, even though most scripts never complete it.

1. You write on spec. No deal, no buyer, no permission. This is where every reputation starts.
2. It reaches a reader. Through a manager or agent query, a contest, a fellowship or a referral. Almost nobody reputable accepts an unsolicited feature script cold anymore.
3. Coverage. An intern or a reader writes a one-page report: logline, synopsis, comments, and a recommendation — pass, consider, or recommend. The logline at the top of that page is what decides whether anyone senior ever opens your script. This is the quiet reason loglines matter so much.
4. The option. A producer pays for the exclusive right to develop the script for a limited period, commonly twelve to eighteen months and renewable, usually at about ten percent of the purchase price, credited against the full price if the film is made. An option is not a sale; it is a reservation.
5. Development. Notes, rewrites, casting attachments, financing. Many scripts die here, which is normal rather than a verdict on the writing.
6. The production draft, then the shooting script. Budget and locations rewrite the script again, scenes are numbered, revisions go out on coloured pages, and the film goes into production — usually with further rewrites during the shoot.

Union and guild rates for writing work are published and revised periodically, so check current minimums rather than working from a figure you half-remember. What matters more at this stage is the thing that does not change: a screenplay has to work as a reading experience even if nobody ever buys it.

What to do next

Read one produced screenplay in your genre in its final form — reading a script that was actually made is the fastest way to internalise the format, and formatting software exists so you stop thinking about it. Then work in this order: a logline that can survive being repeated by someone else, then structure, then pages. Our guide to writing a screenplay walks through the whole process from premise to finished draft.

When you draft, write in real screenplay format from page one. You can format by hand, but it wastes attention on margins that the industry has already settled; the free screenplay formatter shows exactly how each element should sit on the page, and page goal planner turns a finished length into a daily page count so the draft actually gets finished. A first draft is measured in months, not weekends, and the writers who finish are the ones who decided how many pages a day they were going to write.
