Standard Screenplay Format: Margins, Font and Indents

Industry standard screenplays must be formatted in 12pt Courier font with specific margin offsets from the paper's left edge:

  • Left Page Margin: 1.5 inches (provides physical space for three-hole brad binding).
  • Right Page Margin: 1.0 inch.
  • Top & Bottom Margins: 1.0 inch (yielding approximately 54–55 lines per page).
  • Character Heading Indent: 3.7 inches from the left edge (centered block).
  • Dialogue Block Indent: 2.5 inches from the left edge (right margin at 6.0 inches).
  • Parenthetical Indent: 3.1 inches from the left edge.

EXT. HIGHWAY 285 - NIGHT

Telephone poles blur beneath headlights. The desert wind WHISTLES through open window vents.

Inside the cab of a beat-up Ford pickup, MOSS grips the wheel. His knuckles are white with tension.

Just five more miles to the interstate. Don't look back.

A set of high beams appears in the rearview mirror. Accelerating fast.

Common Search Queries

Screenplay Format FAQ: Common Script Formatting Questions

How many pages should a feature film screenplay be?

Many feature screenplays fall around 90–120 pages, depending on genre, pacing, and production needs. Treat this as a common range, not a hard rule; the story and intended format determine the appropriate length.

What font and font size should a screenplay use?

A conventional spec screenplay uses 12-point Courier or a compatible monospaced screenplay font. Monospaced characters help maintain consistent page layout and rough page-to-screen-time expectations.

How do you write a scene heading (slugline)?

Start with INT. for an interior or EXT. for an exterior, name the location, then add the time of day, such as INT. MOTEL ROOM — NIGHT. Keep the heading concise and in uppercase.

What is the difference between a screenplay and a shooting script?

A spec screenplay is written to communicate the story clearly without production-heavy camera instructions. A shooting script is prepared for production and may include scene numbers, locked pages, and other planning details.

What is the difference between (O.S.) and (V.O.)?

(O.S.) stands for Off-Screen: The character is physically in the scene's location (such as yelling from the next room), but not visible to the camera. (V.O.) stands for Voice-Over: The character is not physically present in the room; their voice comes from narration, telephone calls, or internal monologue.

Should action blocks be justified or left-aligned?

Always left-aligned (ragged right). Never justify screenplay text, as justifying creates uneven letter-spacing that disrupts the monospaced Courier timing.
