The Ultimate Guide to Professional Screenplay Formatting

First impressions matter. A poorly formatted screenplay signals amateur hour to Hollywood gatekeepers. Here's everything you need to know about industry-standard formatting.

📏 The Sacred Rules of Page Layout

The Only Acceptable Font

12-point Courier (or Courier New / Courier Prime)

Why? Courier is a monospaced font where every character takes the same width. This ensures:

• Consistent page count - One page ≈ one minute of screen time
• Easy reading - Wider character spacing reduces eye strain
• Industry tradition - Everyone uses it, so should you

Margins That Matter

Top:    1.0 inch
Bottom: 0.5 - 1.0 inch (varies by software)
Left:   1.5 inches (for binding holes)
Right:  1.0 inch

Why the wide left margin? Scripts are hole-punched and bound with brass fasteners. The extra space prevents text from disappearing into the binding.

🎬 Element Formatting Rules

Scene Headings (Sluglines)

INT. COFFEE SHOP - DAY

Anatomy:

• INT. or EXT. - Interior or Exterior
• Location - Specific place (all caps)
• Time of day - DAY, NIGHT, MORNING, SUNSET, etc.

Margin: Flush left, 1.5 inches from page edge

Common mistakes:

• ❌

  Int. Coffee Shop - Day

  (should be all caps)
• ❌

  COFFEE SHOP - INT - DAY

  (wrong order)
• ❌

  INT. COFFEE SHOP - 3PM

  (too specific; use AFTERNOON)

Action (Description)

SARAH, 30s, exhausted, slumps into a booth. Her phone BUZZES.
She ignores it.

Rules:

• Margin: Flush left to right margin
• Tense: Always present tense
• Character introductions: ALL CAPS on first mention, include age
• Sound effects: ALL CAPS (optional)
• White space: Break into short paragraphs (4 lines max)

Pro tip: Action is film language, not prose. Write what the camera sees, not what characters think.

Character Names

                    SARAH

Margin: Centered at 3.7 inches from left edge

Extensions:

• (V.O.) - Voice over (narration)
• (O.S.) - Off-screen (in the scene but not visible)
• (CONT'D) - Continuing dialogue after action break

Examples:

                    SARAH (V.O.)
I should've stayed in bed.

                    SARAH (CONT'D)
But here I am.

Dialogue

                    SARAH
          I can't believe you did that.

Margin: 2.5 inches from left, 2.5 inches from right (narrower than action)

Why narrower? Creates visual distinction on the page. Producers can instantly see dialogue-heavy vs. action-heavy scripts.

Parentheticals

                    SARAH
                 (under her breath)
          Idiot.

Margin: 3.1 inches from left

Purpose: Brief character direction (emotion, delivery, physical action)

Rules:

• Keep it short - 2-3 words max
• Use sparingly - Actors hate being told how to act
• Never use for scene action - That belongs in action lines

Good parentheticals:

• (whispers)

• (beat)

  - Brief pause

• (to John)

  - Who they're addressing

• (laughs)

Bad parentheticals:

• (angrily, because he just found out she lied)

  - Too long

• (stands up and walks to the door)

  - This is action, not a parenthetical

Transitions

                                                   CUT TO:

                                                FADE OUT.

Margin: Flush right

When to use:

• CUT TO: - Only for emphasis (modern scripts omit this)
• FADE OUT. - Only at the end of the script
• DISSOLVE TO: - Time passage
• MATCH CUT TO: - Visual connection between scenes

Pro tip: Most transitions are implied. Don't write

CUT TO:

📄 Page Numbering

Where Numbers Go

• Top-right corner
• 0.5 inches from top
• Followed by a period:

  23.

When to Start Numbering

• Page 1: Title page (no number shown)
• Page 2: First page of script (number shown)

Locked Pages (Production Scripts)

During shooting, pages get "locked" to preserve continuity:

23.
23A.
23B.

If scenes are added, they become A, B, C pages instead of renumbering everything.

📊 Page Count Guidelines

Feature Films

Why the variation? Action scripts have more white space (chase scenes, fights) and thus more pages for the same runtime.

🚫 Common Formatting Sins

Sin #1: Camera Directions

❌ The CAMERA PANS to reveal a dead body.
✅ A dead body lies in the corner.

Why? You're the writer, not the director. Describe what we see, not how we see it.

Exceptions: When the camera move is story-critical:

✅ REVERSE ANGLE - The killer stands behind Sarah.

Sin #2: Overly Detailed Action

❌ Sarah walks across the room, her hand trembling as she
   reaches for the doorknob. She hesitates, takes a deep
   breath, and slowly turns the knob counterclockwise.

✅ Sarah approaches the door, hand trembling. She opens it.

Why? Screenplays are blueprints, not novels. Trust the director and actor to fill in details.

Sin #3: Dialogue Formatting in Action

❌ Sarah says "I love you" to John.

✅                SARAH
          I love you.

Why? Dialogue always goes in dialogue format, never in action paragraphs.

Sin #4: Underlining/Bold/Italics

❌ Sarah is *really* angry.
✅ Sarah SLAMS her fist on the table.

Why? Screenplay formatting doesn't support emphasis beyond ALL CAPS for sounds and first character appearances.

💡 Pro Tips from the Trenches

Tip #1: Use Proper Screenplay Software

Recommended tools:

• Final Draft - Industry standard ($249)
• Laper - Modern, collaborative, AI-powered (free tier available)
• WriterDuet - Cloud-based, real-time collaboration (free tier)
• Highland 2 - Minimalist, Fountain-based (free)

Why? These tools auto-format as you type. You'll never need to manually adjust margins.

Tip #2: Read Professional Scripts

Download scripts from:

• SimplyScripts.com - Free screenplay library
• The Black List - Unproduced gems
• Studio websites - Oscar contenders release scripts during awards season

Study formatting choices in scripts that sold for millions. Notice how lean and visual they are.

Tip #3: The "Skim Test"

Print your first 10 pages. Can someone skim them in 30 seconds and grasp:

• Genre?
• Protagonist?
• Conflict?

If not, you have too much dense description. Add white space.

🎯 Conclusion

Perfect formatting won't sell a bad script, but poor formatting will kill a good one. Master these rules, then forget about them. Focus on storytelling—let software handle the margins.
