Screenplay Format Explained (With an Annotated Example)

Why Screenplay Format Is So Strict

Screenplay formatting looks like arbitrary fussiness until you know what it's for. A script isn't a reading experience — it's a production document. Its layout exists so that a first assistant director can break it down into a shooting schedule, a producer can estimate cost, and everyone can rely on the same rough conversion: one properly formatted page is about one minute of screen time.

That last convention is why the rules matter. Deviate from standard format and you break the page-per-minute estimate, which is the first thing a professional reader checks. Getting format right doesn't make a script good, but getting it wrong marks it as amateur before anyone reads a line.

The Page Specifications

These are the industry defaults, inherited from typewriter-era production and preserved because the timing convention depends on them:

Courier is not a style choice — it's a monospaced font, so its character width is predictable, which is what makes the page-per-minute rule hold. Screenwriting software handles all of this for you.

The Six Elements

Almost everything in a screenplay is one of these six.

1. Scene heading (slugline). All caps, tells us where and when. Format is INT. or EXT. (interior or exterior), the location, then the time of day.

2. Action. Present tense, describing only what an audience can see and hear. Not what a character is thinking, and not camera directions in a spec script. A character's name is capitalised the first time they appear.

3. Character name. Capitalised, indented, sitting above their dialogue.

4. Dialogue. Indented under the character name, in a narrower column than action.

5. Parenthetical. A short direction on how a line is delivered, in brackets under the character name. Use sparingly — if the line only works with a parenthetical, the line usually needs rewriting.

6. Transition. CUT TO: or DISSOLVE TO:, right-aligned. Mostly omitted in modern spec scripts, since a cut is assumed between scenes.

An Annotated Example

INT. RAILWAY CAFE - NIGHT                     <- scene heading

Rain streaks the window. MAYA (30s, coat still  <- action, present tense
buttoned) watches the platform clock. A cold cup   name capitalised on
of tea sits untouched in front of her.             first appearance.

The door bangs. DANIEL comes in shaking off water.

                    DANIEL                     <- character name
              (out of breath)                  <- parenthetical
          You waited.

                    MAYA                       <- dialogue
          Forty minutes.

Daniel sits. He does not take off his coat.    <- behaviour, not thought

                    MAYA (CONT'D)              <- same speaker resumes
          You're not staying, are you.

Maya slides the envelope across the table       <- the visual carries
without looking at him.                            the meaning

                                    CUT TO:    <- transition (optional)

EXT. PLATFORM - CONTINUOUS                     <- CONTINUOUS = no time gap

Note what the example does not do: it never says what Maya feels. "He does not take off his coat" tells the audience he's leaving without a word of interiority. That's the discipline of the form — everything must be visible or audible.

The Rules That Trip People Up

• No interiority. You cannot write "she remembers the summer they met." Find a way to show it, or cut it.
• No camera directions in a spec script. Leave CLOSE ON and PAN TO to the director. You can steer attention by what you choose to describe.
• Keep action paragraphs short. Three or four lines maximum. Dense blocks of text get skimmed by readers.
• CONT'D and (V.O.) vs (O.S.). V.O. (voice-over) is narration from outside the scene's space; O.S. (off-screen) is a character present but not in shot.
• Don't number scenes in a spec script. Scene numbers are added at production stage.

Software

You don't need to set margins by hand. Final Draft is the long-standing industry standard; Fade In and Highland are cheaper paid alternatives; WriterDuet and Arc Studio have free tiers; and Fountain is a plain-text markup format you can write in any editor and convert later. Any of them will produce correctly formatted pages, which means your only real job is the writing.

Where to Go Next

Screenplay structure rewards the same thinking as prose plotting — see How to Outline a Book for turning points that transfer directly to a three-act script. Because screenwriting strips out interiority, dialogue carries far more weight, so The Power of Subtext: Writing Between the Lines is especially worth reading, along with Character Archetypes for building a cast that reads clearly on screen.
