Page Estimation Skill

Invocation Triggers

Apply this skill when:

  • Estimating screenplay length
  • Calculating runtime
  • Tracking page count
  • Validating target length

The Page-to-Screen Rule

Standard Formula

1 page of screenplay ≈ 1 minute of screen time

Genre Adjustments

Genre Adjustment Typical Length
Action 0.8-0.9 min/page 95-115 pages
Comedy 1.0 min/page 90-110 pages
Drama 1.0-1.1 min/page 100-120 pages
Thriller 0.9-1.0 min/page 100-115 pages
Horror 0.9-1.0 min/page 85-100 pages
Animation 0.7-0.8 min/page 75-95 pages

Why It Varies

  • Action-heavy scripts: More white space, faster pace → shorter pages
  • Dialogue-heavy scripts: Dense pages → longer runtime per page
  • Visual storytelling: Less text, more subtext → varies

Estimation Methods

Method 1: Element Count

Rough estimate based on script elements:

Scenes: 60 scenes × 1.5 pages avg = 90 pages
Adjustment for dialogue density: +10%
Estimated: ~99 pages

Method 2: Word Count

Total words: 20,000
Average screenplay: 180-200 words/page
Estimated: 20,000 ÷ 190 = 105 pages

Method 3: Structural Estimate

Act One (Setup): 25 pages
Act Two (Confrontation): 55 pages
Act Three (Resolution): 25 pages
Total: 105 pages

Method 4: Scene-by-Scene

Most accurate:

| Scene | Est. Pages |
|-------|-----------|
| 1 | 2 |
| 2 | 1.5 |
| 3 | 3 |
| ... | ... |
| Total | X |

Fountain Page Count

Title Page

  • Always counts as page 1
  • Not numbered in output
  • Adds ~1 page to total

Scene Headings

  • Each scene heading takes ~2 lines
  • 55-60 lines per page standard
  • Many short scenes = more page overhead

Dialogue vs. Action

  • Dialogue: ~35-40 lines per page (narrower column)
  • Action: ~55-60 lines per page (full width)
  • Heavy dialogue = fewer scenes per page

Elements That Add Length

  • Dual dialogue (takes more vertical space)
  • Parentheticals (extra lines)
  • Transitions (blank lines before/after)
  • Page breaks (forced ===)

Runtime Calculation

Formula

Runtime (minutes) = Pages × Genre Factor

Calculator

Pages: 105
Genre: Thriller (0.95)
Estimated Runtime: 105 × 0.95 = 99.75 minutes
Formatted: 1h 40m

By Scene

| Scene | Pages | Runtime |
|-------|-------|---------|
| 1 | 2 | 2 min |
| 2 | 3 | 3 min |
| ... | ... | ... |
| Total | 105 | 105 min |

Adjusting Length

Too Long

  1. Cut scenes: Remove non-essential scenes
  2. Combine scenes: Merge scenes with similar purpose
  3. Trim dialogue: Reduce line count
  4. Tighten action: Cut verbose descriptions
  5. Enter later/leave earlier: Trim scene edges

Too Short

  1. Add character moments: Deepen relationships
  2. Expand key scenes: Give weight to important moments
  3. Add B-story: Strengthen subplots
  4. Develop obstacles: More complications
  5. Add breathing room: Moments of reflection

Red Flags

  • Feature spec over 120 pages: Instant rejection risk
  • Feature spec under 90 pages: Feels slight
  • TV spec off by more than 5 pages: Format unfamiliarity

Quick Reference

Validation Checklist

  • Total pages within target range
  • Acts properly proportioned
  • No single act dominates
  • Pacing feels appropriate
  • Runtime estimate matches target
