Screenplay Format.The Industry Standard for Story on the Page.

Definition

Screenplay format is the standardized way of writing scripts for film and television, using specific fonts (Courier 12pt), margins, and structural elements so that one page of script roughly equals one minute of screen time. The format includes scene headings (slug lines), action descriptions, character names, dialogue, parentheticals, and transitions. Proper formatting is not a stylistic choice; it is an industry requirement that ensures scripts are readable, consistently timed, and compatible with production workflows. M Studio's AI script generator produces output that follows screenplay conventions, giving you a production-ready starting point for storyboarding.

Key Screenplay Elements

Scene Heading (Slug Line)

Formatted as INT./EXT. LOCATION - TIME OF DAY. Establishes where and when the scene takes place. Example: INT. DETECTIVE'S OFFICE - NIGHT. Every new location or time change requires a new scene heading.

Action Lines

Written in present tense, describing what the camera sees and what characters physically do. Action lines should be visual and concrete, avoiding internal thoughts or novelistic description. Keep paragraphs short (3 to 4 lines max) for readability.

Character Name & Dialogue

The character's name is centered above their dialogue. Dialogue is indented and represents spoken words. The first appearance of a character in action lines uses their name in ALL CAPS.

Parentheticals

Brief direction placed in parentheses between the character name and dialogue, such as (whispering) or (to Sarah). Used sparingly; over-directing actors through parentheticals is considered a mark of amateur writing.

Transitions

Editing instructions like CUT TO:, DISSOLVE TO:, or SMASH CUT TO:, placed at the right margin. Modern screenwriting uses transitions sparingly, as the cut is assumed between scenes.

The One Page Per Minute Rule

The standardized format exists primarily so that script length correlates with screen time. Courier 12-point font with specific margins produces roughly one minute of screen time per page. A 90-page script should yield approximately a 90-minute film.

This correlation is approximate. Dialogue-heavy scripts run faster than their page count suggests because people speak quickly. Action-heavy scripts with sparse description may run longer because visual sequences take more screen time than the brief action lines that describe them.

Understanding this relationship matters during pre-production because it affects budgeting, scheduling, and storyboarding. A 120-page script means a roughly two-hour film, which has implications for everything from shooting days to distribution.

Common Formatting Mistakes

The most common amateur formatting errors include: using non-standard fonts, writing in past tense instead of present, including camera directions (which are the director's domain), writing dense action paragraphs instead of short visual blocks, and over-using parentheticals.

Professional readers, agents, and producers can identify improperly formatted scripts within seconds, and many will not read past the first page if the format is wrong. Proper formatting signals professionalism and respect for the reader's time.

FAQ

Common questions about screenplay format

What font and margins does a screenplay use?

Industry standard is Courier 12-point font. Left margin is 1.5 inches, right margin is 1 inch, top and bottom margins are 1 inch. Dialogue is indented to 2.5 inches from the left and extends to 6 inches. Character names are centered at 3.7 inches. These specifications ensure the one-page-per-minute timing works.

Should I include camera directions in my screenplay?

Generally no, especially for spec scripts (scripts written without a commission). Camera directions like CLOSE ON or PAN TO are considered the director's domain. The writer's job is to describe what happens visually and emotionally, not to direct the camera. Occasional, purposeful camera references are acceptable in shooting scripts.

What software should I use to write a screenplay?

Final Draft is the industry standard. Highland, WriterSolo, and Fade In are popular alternatives. Free options include WriterSolo (web-based) and Fountain (a plain-text markup language). The key is using software that handles formatting automatically so you can focus on the story.

How long should a screenplay be?

Feature film screenplays typically run 90 to 120 pages. Comedies and animation scripts tend toward the shorter end (90 to 100 pages). Dramas and epics may extend to 130+ pages, though anything beyond 120 faces resistance from producers. TV pilots are typically 30 pages (half-hour) or 55 to 65 pages (hour-long).
