Screenwriting Fonts: Why Every Screenplay Uses Courier 12pt

Almost every professional screenplay ever submitted has been set in 12-point Courier. That looks like the film industry being stubborn about a typewriter font — but it isn't nostalgia. Courier at 12pt does a specific job no other typeface does, and understanding that job explains why the convention has survived every technology shift since 1955.

INT. EDITING SUITE — NIGHT

A WRITER stares at a page of monospaced text.

           It's not that the font is beautiful.
           It's that everyone agreed on it.

Set in Courier Prime — the free screenwriter's Courier discussed below.

The one-page-per-minute rule

Here's the thing most explanations skip. A screenplay isn't only a story document — it's a budgeting and scheduling document. Before a frame is shot, producers, line producers, and assistant directors need to estimate running time, shooting days, and cost. The industry's rule of thumb is that one page of correctly formatted screenplay equals roughly one minute of screen time.

That equivalence only holds if everyone uses the same font at the same size with the same margins. Courier is monospaced — every character occupies exactly the same width — so the amount of text on a page is completely predictable. A proportional font like Times or Arial fits far more words per page, and by a variable amount depending on which letters you happen to use. Switch fonts and a 110-page script silently becomes a 95-page script, and your two-hour film is suddenly budgeted as a ninety-minute one.

So the standard isn't aesthetic conservatism. It's the film equivalent of a standard unit of measurement — and that's why deviating from it reads as amateurish to anyone who reads scripts professionally. It's not that they dislike your font; it's that you've broken their ruler.

Where Courier came from

Courier was designed by Howard "Bud" Kettler for IBM in the mid-1950s, intended for the company's electric typewriters. Kettler reportedly named it for the idea of a courier: a letter carrier, something that delivers a message without drawing attention to itself. IBM notably did not lock the design down exclusively, and Courier spread across the typewriter industry and later into computing as a near-universal monospaced face.

Screenwriting adopted it for the ordinary reason that scripts were typed on typewriters, and Courier was what typewriters produced. When word processors arrived, the industry had already built its scheduling maths around Courier's metrics — so the font stayed while the technology underneath it changed completely. Conventions like this survive not because anyone defends them, but because too much downstream infrastructure depends on them.

Which Courier should you actually use?

"Courier" is several different fonts wearing the same name, and they are not equally good.

Courier Prime deserves the recommendation. It was commissioned by screenwriter John August through Quote-Unquote Apps and released free in 2013, with the explicit goal of fixing Courier's real weaknesses for people who stare at it all day: the weight is more even, the italic is a genuinely drawn italic rather than a mechanical slant, and the bold is actually bold. Critically, it keeps Courier's character widths, so switching to it will not change your page count by a single line. Courier Prime on Google Fonts.

Because it's under the SIL Open Font Licence, it's free for commercial use with no strings — worth noting if you're producing materials around the script as well. (If licence categories are unfamiliar, see Understanding Font Licensing.)

The formatting spec, briefly

Font choice is one part of a broader standard. The commonly used values:

• Font: 12-point Courier (or Courier Prime), single-spaced
• Paper: US Letter (8.5″ × 11″) — even outside the US, for submissions to US productions
• Left margin: 1.5″ (the extra width leaves room for brads/binding)
• Right margin: approximately 1″
• Top and bottom margins: 1″
• Page numbers: top right, followed by a period; the first page is unnumbered
• Scene headings and action: flush to the left margin, in caps for headings
• Character names: indented roughly 3.7″ from the page edge, in caps
• Dialogue: indented roughly 2.5″ from the page edge, about 3.5″ wide
• Parentheticals: indented between the two, around 3.1″

Exact indents vary by a fraction depending on which style guide you consult, and this is precisely why nobody sets these by hand. Screenwriting software applies them automatically as you type — which is the real argument for using it.

Software does this for you

Every dedicated screenwriting application defaults to 12-point Courier and the standard indents: Final Draft (the industry default), Fade In, WriterDuet, Highland, Celtx, and the free, plain-text-based Fountain markup ecosystem. If you're writing in one of these, the font question is already answered and you can stop worrying about it.

If you're writing in Word or Google Docs, you can absolutely produce a correctly formatted script — set Courier Prime at 12pt and configure the margins and indent styles above — but you'll spend energy on formatting that the dedicated tools handle invisibly.

Is it ever acceptable to deviate?

For a spec script you're submitting to agents, managers, producers, or competitions: no. The convention exists so readers can assess pace and length instantly, and a non-standard font signals that you haven't read enough scripts to know better. That's an unforced error before your first line is read.

There are legitimate exceptions, and they're all documents that aren't the screenplay itself:

• Title pages stay in Courier too, but the title is often centred and sometimes in caps or quotes — modest variation is tolerated.
• Pitch decks, lookbooks, and series bibles are marketing documents, not production documents. Design them properly — see How to Pair Fonts.
• Stage plays and radio drama follow different conventions; many use proportional fonts and their own layout rules.
• Graphic novel and comics scripts have no single standard, and Courier is common but not required.
• Shooting scripts and production paperwork add lock-page numbering and revision colours on top of the same font.

A note on "script fonts" — two different things

Searches for "script font" collide two unrelated meanings, so it's worth separating them clearly:

• Screenwriting fonts — Courier, the subject of this article: monospaced, plain, functional.
• Script typefaces — flowing, connected, calligraphic letterforms that imitate handwriting, used for wedding invitations, logos, and packaging. Completely unrelated to screenplays, and covered in our script & handwriting guide.

If you arrived here looking for elegant handwriting-style fonts, that second link is the one you want.

The short version: use Courier Prime at 12 points, let your software handle the indents, and spend the attention you saved on the writing. In a document whose entire purpose is to be measured, the most useful typeface is the one nobody notices.
