How do I outline a screenplay?

By the WriteLoom editorial teamUpdated 2026-09-02
Key facts
  • Most screenwriters outline on index cards or a beat sheet before drafting.
  • A feature typically runs 40 to 60 scenes across three acts.
  • Page targets per act: roughly 25, 55, and 30 in a 110-page feature.
  • The midpoint, around page 55, is where the protagonist's approach fundamentally changes.
  • Screen structure is tighter than novel structure because runtime is fixed.
Direct answer

Outline a screenplay in two passes: a beat sheet of 12 to 15 story turns, then a scene list of 40 to 60 scenes with page targets. Screen time is fixed, so structure has to be visible before drafting. Index cards, a beat sheet, or a scene board all work; what matters is seeing the whole shape at once.

Chapter i·Why it matters

A novel can absorb a saggy middle over 400 pages. A screenplay cannot: 20 slack pages is 20 minutes of an audience checking their phones. Outlining with page targets catches the sag while it is still a card you can move, rather than a scene you spent a week writing and now cannot cut.

Chapter ii·What to include

  • A one-line logline that the outline has to serve.
  • Twelve to fifteen beats: opening image, inciting incident, act breaks, midpoint, climax.
  • A scene list with a page target beside each scene.
  • The want and the need for the protagonist, written explicitly.
  • Act page totals checked against a 110-page target.
  • A pass that asks of every scene: what changes here?

Chapter iii·Example

A writer's outline showed 34 pages between the act one break and the midpoint, against a 30-page target, and eight scenes in that stretch with no change of state. Three cards came out before she wrote a word of dialogue.
