Professional AI Screenplay Editor: Industry Standards 2025
Hollywood has strict formatting rules. Professional AI screenplay editors automate industry standards so your script looks production-ready—not amateur.
What "Industry Standard" Actually Means
The Non-Negotiables
Every professional screenplay must follow:
- Courier 12pt font (monospace, always)
- 1.5" left margin (binding space)
- 1" right, top, bottom margins
- 55 lines per page (timing: 1 page ≈ 1 minute screen time)
- Specific element spacing (2 lines before scene headings, etc.)
Why it matters: Producers reject incorrectly formatted scripts without reading.
Industry-Standard Formatting Elements
1. Scene Headings (Sluglines)
Format:
INT. COFFEE SHOP - DAY
Rules:
- Always UPPERCASE
- Starts with INT. (interior) or EXT. (exterior)
- Location (COFFEE SHOP)
- Time of day (DAY, NIGHT, MORNING, EVENING)
Common mistakes:
- ❌
Int. Coffee Shop - Day(lowercase) - ❌
COFFEE SHOP - DAY(missing INT/EXT) - ❌
INT COFFEE SHOP DAY(missing periods/dashes)
AI editors (Laper AI, Arc Studio) auto-format when you type "INT" or "EXT".
2. Character Names
Format:
SARAH
Rules:
- Always UPPERCASE
- Centered above dialogue
- Use parenthetical for off-screen:
SARAH (V.O.)= voice-overSARAH (O.S.)= off-screenSARAH (CONT'D)= continues after interruption
Common mistakes:
- ❌
Sarah(lowercase) - ❌
SARAH:(colon not needed)
3. Dialogue
Format:
SARAH
I can't believe you did that.
Rules:
- 3.5" left margin, 2.5" right margin (narrower than action)
- Natural speech (contractions, fragments)
- Max 3-4 lines per speech (long monologues break readability)
Common mistakes:
- ❌ Full-width margins (looks like action text)
- ❌ Formal speech ("I cannot believe you accomplished that")
4. Action (Description)
Format:
Sarah slams her laptop shut. Coffee spills across the table.
Rules:
- Present tense (not past)
- Full-width margins (1.5" left, 1" right)
- Short paragraphs (3-4 lines max)
- White space = readability
Common mistakes:
- ❌ Past tense ("Sarah slammed")
- ❌ Camera directions ("We see Sarah slam")
- ❌ Dense blocks (10+ line paragraphs)
5. Transitions
Format:
CUT TO:
FADE IN:
Rules:
- Right-aligned (except FADE IN)
- Use sparingly (editors cut most transitions)
- Common: CUT TO, FADE IN, FADE OUT, DISSOLVE TO
Common mistakes:
- ❌ Overusing transitions (every scene doesn't need CUT TO)
- ❌ Left-aligned transitions

Common Formatting Mistakes (& How AI Fixes Them)
Mistake 1: Inconsistent Character Names
Problem:
SARAH talks to JOE.
Later:
Sarah: "I don't believe you."
Joe (angrily): "It's true!"
AI Fix:
⚠️ Inconsistent character names detected:
- "SARAH" vs "Sarah" (use SARAH)
- "JOE" vs "Joe" (use JOE)
Auto-fix applied.
Mistake 2: Missing Scene Headings
Problem:
INT. COFFEE SHOP - DAY
Sarah types on her laptop.
The barista approaches. ← Missing scene heading if location changes
AI Fix:
⚠️ Potential missing scene heading at line 23.
Add: INT. COUNTER - DAY?
Mistake 3: Camera Directions
Problem:
CLOSE-UP on Sarah's face. We ZOOM IN on her eyes.
AI Fix:
⚠️ Camera directions detected (CLOSE-UP, ZOOM IN).
Remove? Screenplay should focus on story, not cinematography.
Mistake 4: Overly Long Action Blocks
Problem:
Sarah walks into the coffee shop and looks around nervously before approaching the counter where the barista stands waiting and she orders a double espresso while glancing at the clock which shows 11:47 PM and she realizes she's running out of time to finish her screenplay...
(150+ words, unreadable)
AI Fix:
⚠️ Line 45: Action block exceeds 4 lines.
Suggested rewrite:
Sarah enters the coffee shop, nervous. She orders a double espresso.
The clock reads 11:47 PM. She's running out of time.
Conclusion
Professional AI screenplay editors make industry-standard formatting effortless:
✅ Automatic formatting (Courier 12pt, standard margins) ✅ AI validation (catch errors before export) ✅ Multiple standards (US, UK, Netflix) ✅ Production-ready exports (locked PDFs, scene numbers) ✅ Submission compliance (contest anonymity, agent requirements)
Our recommendation: Use Laper AI for writing (AI + collaboration). Export to Final Draft for final polish if submitting to conservative producers.
Format = Credibility. Get it right, or get rejected unread.
