Why formatting matters

Screenplay formatting isn't decoration. It's a shared contract between the writer, the reader, and every department that will later turn the page into a shot. Because the format is standardized, one properly formatted page runs roughly one minute of screen time — so a 110-page script tells a producer the movie runs about 110 minutes without anyone timing a single scene. Break the format and you break that trust on page one.

Page setup

US Letter (8.5 × 11 in). Left margin 1.5 in, right margin 1.0 in, top and bottom margins 1.0 in. Page numbers go in the top-right corner starting on page 2, followed by a period. No header on page 1. No footer, ever.

Font: why Courier

12-point Courier — Courier Prime, Courier Final Draft, or Courier New. It's monospaced, which means every character occupies the same horizontal space. That property is what makes the one-page-per-minute rule reliable. Don't switch to Times New Roman, Arial, or a "cleaner" font to fit more on the page. Readers can tell within three seconds, and it signals a first-time writer.

The eight elements

Every line in a screenplay is one of eight block types. Learn these and you know screenplay format.

  1. Scene heading (slug line) — INT. LOCATION - DAY
  2. Action — what we see and hear, present tense.
  3. Character — the speaker's name, ALL CAPS.
  4. Dialogue — what the character says.
  5. Parenthetical — brief delivery cue like (whispering).
  6. TransitionCUT TO:, FADE OUT:, right-aligned.
  7. ShotCLOSE ON, ANGLE ON — use sparingly.
  8. Note — a private writer note; never exports to a final draft.

Scene headings (slug lines)

Always ALL CAPS. Always start with INT. (interior), EXT. (exterior), or INT./EXT. (both). Then the location, then a hyphen, then the time of day.

INT. AFRICAN DESERT OUTPOST - DAY

EXT. ODESSA TRAIN STATION - NIGHT

INT./EXT. TRUCK - MOVING - DAWN

Action lines

Present tense. Only what a camera can film or a microphone can record — no interior thoughts, no backstory dumps. Introduce a character in ALL CAPS the first time they appear, then switch to normal case. Keep paragraphs short: one to four lines each.

The sun burns across an endless sea of sand.

A lone soldier — STEPHAN, 30s, cracked lips, hollow
eyes — stumbles over a dune. His radio crackles.

Character & dialogue

Character cues sit 3.7 in from the left edge, ALL CAPS. Dialogue sits 2.5 in from the left and 2.5 in from the right. Parentheticals go on their own line, 3.1 in from the left, and only when the delivery genuinely matters — never as a substitute for action.

                    STEPHAN
          Just a few more clicks.

                    COMMANDER (V.O.)
              (over the radio)
          You are lost, soldier.

Modifier tags — (V.O.) for voiceover, (O.S.) for off-screen, (CONT'D) when the same character speaks again after action — sit on the same line as the character cue.

Transitions & shots

Transitions are right-aligned and always end in a colon: CUT TO:, DISSOLVE TO:, SMASH CUT TO:. Most modern specs drop transitions entirely except for FADE IN: at the top and FADE OUT. at the bottom. Shot descriptions like CLOSE ON or ANGLE ON should be reserved for moments the reader must see exactly the way you see them — the director will handle the rest.

Modern spec-script conventions

Software that formats for you

Handling every margin, cue indent, and page break by hand is a losing game. Screenwriting software applies the format automatically as you type — Enter after a character cue jumps to a dialogue block, Tab cycles element type — so you focus on the story, not the ruler.

SceneSmith Studio — screenwriting software built around the format

SceneSmith Studio applies industry-standard screenplay formatting automatically. Type int desert day and it becomes INT. DESERT - DAY. PressEnterafter a character name and the next line is dialogue. PressTabto cycle element type without moving your caret.

Frequently asked questions

What font is used in screenplays?

Industry standard is 12-point Courier (Courier Prime, Courier Final Draft, or plain Courier New). The monospaced font is what makes the 'one page equals roughly one minute of screen time' rule work.

What are the standard screenplay margins?

Left margin 1.5 inches, right margin 1 inch, top and bottom margins 1 inch. The wider left margin leaves room for hole-punching and binding.

How wide is dialogue on a screenplay page?

Dialogue is indented 2.5 inches from the left edge and 2.5 inches from the right edge, giving it a block width of roughly 3.5 inches.

How wide is a character name (cue) on the page?

Character cues sit 3.7 inches from the left edge of the page and are always in ALL CAPS.

Do I still need CONTINUED and MORE tags?

No. Modern spec scripts drop (CONTINUED) at page breaks and (MORE)/(CONT'D) on split dialogue. Production drafts may keep them; specs shouldn't.

What's the difference between a spec script and a shooting script?

A spec is written to sell — no scene numbers, no camera direction, minimal parentheticals. A shooting script is the production version with scene numbers, revision colors, and technical detail.
