How to Format a Screenplay: The Complete Guide

Screenplay format looks intimidating from the outside — all those capital letters, the strange margins, dialogue floating in the middle of the page. But here's the secret every working writer knows: screenplay format is not decoration. It's a machine. Learn how to format a screenplay properly and every page becomes a predictable unit of screen time, every element tells the production team exactly what it's for, and every reader can fall into your story without friction. Script formatting exists so nobody has to think about it.

This guide covers everything: the page setup, the seven element types, and the mistakes that make professional readers wince on page one.

The Foundation: Courier 12pt and the Standard Page

Every screenplay is written in 12-point Courier (or a Courier variant like Courier Prime). This isn't nostalgia for typewriters — it's math. Courier is monospaced, so every character takes the same width, which means a page of properly formatted screenplay translates to roughly one minute of screen time. Producers budget with that number. Change the font and you break the clock. That relationship is the whole reason the one-page-per-minute rule works.

The standard page setup:

  • Paper size: 8.5" x 11" (US Letter), even if you live somewhere metric
  • Left margin: 1.5" (the extra half inch accommodates brads for a printed, bound script)
  • Right margin: 1" (ragged, never justified)
  • Top and bottom margins: 1"
  • Page numbers: top right corner, followed by a period, starting on page 2

That's the canvas. Now the elements that live on it.

The Seven Elements of Screenplay Format

Everything in a screenplay is one of seven element types, each with its own indentation. Here they all are in a single example:

INT. DINER - NIGHT

The last customer is gone. RUTH, 60s, wipes the counter
with the focus of someone avoiding a conversation.

The door CHIMES. She doesn't look up.

MARCUS (O.S.)
You're closed.

RUTH
Sign says so.

MARCUS, 30s, rain-soaked, slides onto a stool anyway.

MARCUS
(counting out change)
Coffee. Whatever's left in the pot.

She pours it. Watches him drink.

CUT TO:

1. Scene heading (slugline). Always capitalized: INT. or EXT., the location, a dash, then time of day. It tells production where and when. Get the anatomy right every time — there's a full breakdown in our guide to scene headings and sluglines.

2. Action. Left-margin paragraphs describing what we see and hear. Present tense, always. Keep paragraphs to four lines or fewer; dense blocks of action read slow, and slow is death. Capitalize a character's name the first time they appear (RUTH, 60s), and capitalize significant sounds (The door CHIMES).

3. Character name. Centered-ish (technically indented about 2.2" from the left margin), all caps, sitting directly above dialogue. Extensions like (O.S.) for off-screen or (V.O.) for voice-over go on the same line.

4. Dialogue. Indented roughly 1" from the left margin in a column about 3.5" wide. Never centered — it just looks centered because of the narrow column.

5. Parenthetical. A brief acting or delivery note tucked between the character name and the line: (counting out change). Use sparingly. If the line needs a parenthetical to make sense, the line usually needs a rewrite.

6. Transition. CUT TO:, DISSOLVE TO:, SMASH CUT TO: — right-aligned, all caps, ending in a colon. Modern spec scripts use them rarely, because a new scene heading already implies a cut.

7. Shot. CLOSE ON THE KNIFE. or ANGLE ON RUTH. — an all-caps line directing the reader's eye. In a spec script, use these almost never. Directing from the page is the director's job; your job is making the shot inevitable through the writing.

Special Cases Worth Knowing

FADE IN: and FADE OUT. Traditionally, a script opens with FADE IN: on the left margin and closes with FADE OUT. followed by THE END. Some writers now skip the opener. Nobody will reject you either way.

MORE and CONT'D. When dialogue breaks across a page, (MORE) goes at the bottom and (CONT'D) follows the character name at the top of the next page. When a character speaks, is interrupted by an action line, and speaks again, their second cue also takes (CONT'D). Good software handles all of this automatically.

Montages and intercuts have their own conventions — lettered or dashed lists for montages, INTERCUT for cross-cut phone calls. They're common enough that you'll want to learn the standard patterns rather than improvise.

The title page is its own small discipline: title, "Written by," your name, contact info in a corner, and nothing else. No date, no draft number on a spec, no WGA registration number.

The Mistakes Readers Notice Instantly

Professional readers see hundreds of scripts. These are the tells that mark a script as amateur before the story gets a chance:

  1. Wrong font. Times New Roman is an instant giveaway. So is anything bold, and so are font-size tricks to cheat the page count.
  2. Past tense action. "Ruth wiped the counter" reads like a novel. Screenplays live in the present: "Ruth wipes the counter."
  3. Camera direction everywhere. "We ZOOM IN as the CAMERA PANS across..." A spec script sells the movie, not the shot list.
  4. Unfilmables. "Ruth thinks about her late husband and feels a wave of regret." If a camera can't photograph it, it doesn't belong in an action line. Find the behavior that shows it — the principle behind show, don't tell.
  5. Overstuffed parentheticals. A parenthetical on every line reads as distrust of your actors and your dialogue.
  6. Chunky action paragraphs. Eight-line blocks of description signal a writer who hasn't learned that white space is pacing.
  7. Inconsistent sluglines. INT. DINER - NIGHT on page 3 and INT. RUTH'S DINER - NIGHT on page 40 for the same place. Production breakdowns depend on consistency; pick one name and keep it.

None of these mistakes will sink a brilliant script on their own. But readers use format as a proxy for professionalism, and a clean script buys your story goodwill it will need later.

Let the Software Do the Formatting

Here's the practical truth: no working screenwriter formats manually. Margins, indents, element cycling, (CONT'D)s — this is exactly the work software should do while you think about the scene. Dedicated screenwriting tools handle it automatically; type INT. at the start of a line in a free screenwriting app like Quillit and it becomes a scene heading, hit Enter and Tab and you're cycling through character and dialogue. Word processors, by contrast, fight you on every element.

Learn the rules in this guide well enough to recognize when something looks wrong — then let the tool enforce them so your attention stays where it belongs. Format is the price of admission, not the art. Pay it cleanly, then go write something a reader can't put down.
