How to Format a Screenplay Correctly

The first time I sent a screenplay to an actual reader — not a friend, an actual industry reader — I got back a one-sentence email: "The format is off. Fix it and resend." That was it. No note on the story, nothing about the characters, zero engagement with the 90 pages I'd spent three months writing. Just a polite door closing.

I spent the following afternoon printing my script next to a produced screenplay I found online. The difference was immediately obvious. Mine looked like a thriller novel that had been roughly translated into something screenplay-shaped. The margins were wrong, my action lines ran to six and seven sentences, and I had a CUT TO: between every single scene. I'd written the whole thing without once asking whether it looked right.

Here's what nobody explains clearly enough when you're starting out: screenplay format isn't bureaucratic decoration. It's a functional system, and breaking it has real consequences that have nothing to do with the quality of your story.

Why the format is so specific — and why it actually matters

The rigidity of screenplay format exists for a single, practical reason: one correctly formatted page equals approximately one minute of screen time. Producers budget from that equation. Production designers schedule from it. Line producers plan entire shoot days around page counts. When you break the format, you break the math that the entire industry depends on downstream, which is why readers react to bad formatting more sharply than seems reasonable until you understand what's at stake.

The look: 12-point Courier or a Courier variant (Courier Prime is excellent and free), specific margins, and a rhythm of white space that keeps pages airy rather than dense. You should never set any of this manually — dedicated software handles it perfectly. Beat is free and excellent on Mac. WriterDuet has a generous free tier and runs in any browser. Fade In is a one-time purchase worth every cent. Highland 2 and Final Draft are the other main options. They all produce pages that look identical to each other. If you haven't settled on a story to format yet, start with how to write your first screenplay and come back here once you're actually drafting.

Sluglines: the GPS of your script

Every scene starts with a slugline — also called a scene heading — that answers three questions: inside or outside, where exactly, and when. The structure is always: INT. or EXT., then the location, then a dash, then the time of day:

INT. COFFEE SHOP — DAY
EXT. PARKING GARAGE — NIGHT
INT./EXT. MOVING CAR — DUSK

CONTINUOUS means the scene follows directly from the one before it with no time cut. LATER means time has passed in the same location. INT./EXT. is for scenes where the camera moves between inside and outside — typically car scenes.

The mistakes I see constantly, because I made all of them:

• Atmospheric sluglines. "INT. THE KIND OF DINER WHERE HOPE GOES TO DIE — NIGHT" is evocative prose fiction. The slugline is for the location manager. Save the color for the action line that follows.
• Inconsistent location names. If it's MARCUS'S APARTMENT on page 6, it must be MARCUS'S APARTMENT on page 54 — not "MARCUS'S PLACE" or "MARCUS'S FLAT." Production scheduling software treats those as different locations. So will whoever breaks down your script.
• Specific times of day. "3:47 AM" doesn't belong in a slugline. You have DAY, NIGHT, DAWN, DUSK, and the special-case words listed above. Exact times live in title cards or dialogue, not scene headings.

Action lines: present tense, visual, and ruthlessly lean

Action lines — also called description or direction — are where most first scripts quietly fail. The rules sound simple: present tense, only what can be seen or heard on screen. Applying them with actual discipline is harder than it looks.

You cannot write "Elena still hasn't forgiven herself for leaving." A camera cannot photograph guilt or regret. You can write what Elena does because of that unresolved feeling — what she reaches for, what she avoids, how she holds herself in the scene. That translation from internal state to external behavior is the specific work of screenwriting. It's also harder and usually better than explaining.

My working rule after too many bloated drafts: no action block longer than four lines, and most should be two or three. Dense grey paragraphs make professional readers skim, and a skimming reader misses the detail you buried in the fifth sentence of your seventh line. White space is not laziness on the page — it's what makes a script read like a film rather than a manual. If your pages feel crowded, you're probably overwriting, and the fix is almost always cutting rather than rephrasing.

The deeper craft here is telling the story in images — trusting the audience to feel what the camera shows rather than being told what to feel about it. That skill starts in the action lines. Format is where visual storytelling either lives on the page or dies there.

One page, one minute. The entire industry budgets on that equation — which is why every formatting rule exists.

Dialogue blocks: character names, parentheticals, and the caps rules

Character names go in all caps, centered, directly above their dialogue. The first time a character appears anywhere in the script — in an action line — their name gets capitalized to flag the introduction:

NORA, 40s, silver-haired and unimpressed, surveys the damage with the expression of someone who saw this coming.

After that introduction, she's just Nora in action lines. Not NORA every time she appears. Overcapitalizing character names in action lines after their introduction reads as shouting — or as a writer who doesn't know the convention.

Significant sounds get capitalized in action: a GUNSHOT, the CRACK of glass, a PHONE BUZZING on a tile floor. Use this sparingly. I went through a phase of capitalizing everything that felt important, and the pages read like someone perpetually startled.

Parentheticals — those (beat), (quietly), (with contempt) instructions that sit under a character name — should be nearly absent from a well-written script. Directors resent being given line readings. Actors resent it even more. Use one only when the meaning of a line completely inverts without it: "Great. Perfect. Wonderful." meaning the opposite of what it says. If you find yourself writing parentheticals for most of your dialogue, the problem is upstream — the dialogue isn't carrying its own tone, and the fix is rewriting the lines, not labeling them. The deeper version is subtext: what characters don't say is almost always more interesting than what they do.

Transitions and camera directions: mostly, just don't

CUT TO: between every scene is a relic from an earlier era. A new slugline already tells the reader you're cutting — the transition is redundant. The occasional SMASH CUT TO: or MATCH CUT TO: for a deliberate, meaningful effect is perfectly fine. A script with transitions between every scene reads like it was written in 1985 and hasn't been opened since.

Camera directions in a spec script — CLOSE ON, ANGLE ON, WE PUSH IN — tend to annoy directors because they implicitly claim authority over decisions directors consider their own territory. In a script you'll direct yourself, you have latitude. In a spec script written to sell or attract attention, camera directions mostly just clutter the page without earning their space.

The exception: you can direct the reader's eye with pure description. Putting "The key sits in the ashtray." alone on its own line as a single-sentence action block is a close-up — without naming a camera move. That kind of control through selection and white space is the sophisticated version, and readers with experience recognize it immediately.

Format mastered is format invisible — for you and for the reader. Once it disappears, only your story remains.

The title page: aggressively boring on purpose

Centered, about a third down the page: the title. Below it: "Written by." Below that: your name. Contact information in the bottom right corner. That's the complete title page. No draft number, no WGA registration number, and especially no copyright symbol — which reads as paranoid in a way that's hard to explain to the uninitiated but is immediately recognized by anyone who reads scripts professionally. No taglines, no epigraphs, no images.

I put a tagline on my second script. I thought it was atmospheric and evocative. I cringe about it now. A flashy title page has never once helped a script. It has occasionally hurt one by setting the wrong expectation before page one.

Page count: the silent rejection

Feature scripts live between 90 and 115 pages. Comedies and horror tend toward the shorter end. Prestige dramas get a little more room. A first-time writer submitting a 140-page script is facing a quiet presumption of inexperience before anyone reads the first scene — not because 140-page scripts can't be good, but because the count signals a writer who hasn't learned to self-edit, which signals a specific kind of development conversation that most readers would rather not initiate.

Short films: aim under 15 pages. Under 10 if you're financing it yourself — your future production budget will appreciate the restraint, and see what production actually costs in sweat and money if you haven't had that particular education yet.

If your draft runs long, the solution is never shrinking margins or adjusting font size. Readers catch both tricks immediately, and they're actively worse than just being long. The real answer is cutting in the rewrite: late entrances into scenes, early exits from them, subplots that don't serve the central story, and that favorite scene that's good in isolation but costs pace everywhere around it.

The formatting mistakes that get scripts dismissed fastest

• Wrong font. Anything other than Courier or a Courier variant at 12pt breaks the page-per-minute math and announces itself to experienced readers by feel.
• Unfilmable interiority. Thoughts, emotional backstory, psychological states in action lines. If a camera can't film it, it doesn't go on the page.
• Bolded or underlined dialogue. Trust the words to do the work. If they need typographic emphasis to land, they need to be rewritten.
• CONTINUED at page breaks. Turn this off in your software settings. Modern scripts don't use it. It eats page space and looks dated to anyone who reads scripts regularly.
• Wryly overload. "(wryly)," "(with irony)," "(sarcastically)" under character names are almost always a symptom of dialogue that isn't doing its job on its own.

The formatting questions that trip up new writers almost always have simple, learnable answers — once someone explains them plainly.

Format questions I get asked most often

How do I format a phone call? Three options. Intercut between the two locations (write INTERCUT after establishing both sides of the call). Stay on one side and let the audience hear only half the conversation. Or use (V.O.) for the unseen caller, which works when keeping the audience on one side is the point. The intercut is standard for scenes where both parties' reactions matter.

What about text messages on screen? Modern convention is genuinely flexible. "ON SCREEN:" followed by the text, formatted as its own indented line, reads clearly. Or describe the phone screen in an action line. Pick a system, stay consistent throughout the script, keep it scannable.

How do I handle flashbacks? Add FLASHBACK to the slugline — "INT. CHILDHOOD KITCHEN — DAY (FLASHBACK)" — and mark the return with BACK TO PRESENT. A broader caution: opening on page one with a flashback is a reflex move that most readers are exhausted by. The format is simple; whether it serves your specific story is the harder question.

Montages? "MONTAGE:" followed by dashed bullets, or a series of quick mini-sluglines. Both are standard. Clarity wins over cleverness every time.

Do these small conventions really matter? Individually, no — readers shrug at minor variations done consistently. What matters is the cumulative impression. A script that handles fifty small conventions cleanly tells the reader: this person has read screenplays. That credibility buys goodwill for your actual story, which is the real point. Clean format doesn't make a script good. But bad format gives a reader permission to stop before they find out whether the story is. The real work lives in the story arc — format is just what gets it read in the first place.

How long it actually takes to learn this

One focused weekend. I say that from experience, not optimism. Here's the method that worked for me: I downloaded two produced screenplays for films I knew well — well enough that I could read the pages and immediately picture the movie — and read them slowly, specifically looking for how they handled every convention I'd been unsure about. Then I went back through my own first ten pages and reformatted them line by line against what I'd just read.

After that weekend, formatting became automatic, the way typing is automatic. I never thought consciously about margins again. That's the goal: format so fluent it's invisible, to you and to the reader. Once it's invisible, the only thing left on the page is your story — which is exactly the fight you want to be having.
