Screenplay Format 2026: Margins, Font Size and Cheat Sheet

Screenplay format is boring. Margins, fonts, slugs, parentheticals,none of it makes your story better on the page. But get it wrong, and readers notice. Producers notice. The script looks amateur before a single line of dialogue is read. So you need to know the rules, even if your only goal is to never think about them again.

Screenplay Format at a Glance: The Cheat Sheet

These are the standard US screenplay format settings. Set them once (or use software that applies them automatically) and every element lands where readers expect it:

One page in this format runs roughly one minute of screen time. You can verify your own script with the free script time calculator tool, and generate a correct cover page using the title page maker generator.

This guide covers the non-negotiable technical specs: Courier Prime (or Courier 12pt), margins, scene headings, and the rest of the formatting skeleton that the industry expects in 2026. We'll explain why each rule exists—not just "because that's how it's done," but the practical reasons rooted in timing, readability, and production logistics that keep these standards in place. By the end, you'll have a clear reference you can trust, and you'll understand why tools that handle formatting automatically, so you can focus on story, are increasingly the default for serious writers working professionally.

If you landed here from script writing format or industry standard screenplay format while still outlining, read idea to first draft first so you are not polishing margins on scenes you will cut. Fellowship-style clarity expectations (not a promise of placement) are summarized in the Academy Nicholl Fellowships in Screenwriting public reading criteria.

Why Screenplay Format Exists (Beyond Tradition)

Screenplay format didn't emerge from a committee of pedants; it emerged from production necessity. A single script page, in standard format, translates to roughly one minute of screen time. That rule of thumb is why line producers and assistant directors can schedule a shoot: they read page count and get a workable estimate of shooting days and budget allocation. Mess with margins or font size, and that correlation breaks down entirely. Your "90-page" script might actually run 110 minutes, or 75 minutes. Suddenly you're the writer who broke the budget model before filming even began.

Format also creates a shared language. When a reader sees INT. COFFEE SHOP - DAY, they know instantly: interior, location, time of day. When they see a character name in caps above dialogue, they know who's speaking without scanning. Consistency lets everyone,directors, actors, department heads,parse the document quickly. In a business where time is money, a script that obeys convention is a script that gets read instead of skimmed.

Format is the interface between your story and the machine that will turn it into a film.

So the "boring" rules aren't arbitrary. They're the interface between your story and the machine that will turn it into a film or show. Learn them once, and you can either apply them manually forever or use software that applies them for you. Either way, you need to know what correct looks like.

One more thing: format builds trust. When a development exec or a contest reader receives a script that looks correct from line one, they assume the writer knows what they're doing. When they see wrong margins, mixed fonts, or inconsistent slugs, they assume the opposite,and that assumption colors how they read every page. Getting format right is the lowest-friction way to signal that you're ready for the next step.

Fonts: Courier, 12pt, and Why It Still Matters in 2026

The industry standard is a monospaced serif font at 12-point size. Courier is the classic; Courier Prime is the modern, slightly more readable variant (better kerning and clarity on screen) that has become the preferred choice for many studios and fellowships. Some readers still expect "Courier" on the nose,if a submission guideline says "Courier 12pt," use that. When they don't specify, Courier Prime 12pt is the safe, professional default.

Why Monospace?

Monospace means every character occupies the same horizontal space. That predictability is what makes the one-page-per-minute rule reliable. Proportional fonts (like Times or Arial) compress some letters and stretch others; page counts would vary with word choice and punctuation. With Courier (or Courier Prime), a page of dense action and a page of sparse dialogue still occupy roughly the same physical space, so page count stays a meaningful proxy for length.

There's a second reason: scripts have been set in Courier for decades. Readers are conditioned to it. Changing the font doesn't make you look innovative; it makes you look like you don't know the format. Stick to 12pt. No 11pt to squeeze in an extra scene, no 14pt to hit a page count. Both tricks are visible and frowned upon.

Margins: The Invisible Skeleton

Standard screenplay margins are designed to produce that one-page-per-minute result and to leave room for binding and notes. Get them wrong, and your script will look off even if the content is perfect.

Page Margins

Left margin: 1.5 inches. Right margin: 1 inch (or 1.25 for some house styles). Top and bottom: typically 1 inch. The left margin is larger to allow for three-hole punching; the right is tighter because dialogue and action rarely extend to the full line. These aren't numbers you need to memorize,you need a tool that applies them. Manually setting margins in a word processor is error-prone and unnecessary when dedicated software does it correctly by default.

Element-Specific Margins

Each element type has its own horizontal position. Scene headings (slugs) start at the left margin (1.5"). Action runs from 1.5" to about 7.5" (so roughly 6" of text width). Character names are centered or placed at approximately 3.7" from the left (depending on the exact standard). Dialogue is inset from both sides,typically 2.5" from the left and 2.5" from the right (or 2" / 2"), creating a column of roughly 3.5" to 4" in width. Parentheticals sit inside the dialogue column, indented a bit more. Transitions (CUT TO:, FADE IN., etc.) are often right-aligned or placed at a specific position (e.g., ending around 7" from the left).

The exact numbers can vary slightly between studios and contests,some use 1" left for scene headings with a 0.5" indent for continued headings, and so on. The point is: there is a precise grid. Amateur scripts betray themselves with inconsistent indents, dialogue that runs too wide, or scene headings that don't align. Professional scripts look uniform because the software (or the writer) has applied the grid correctly.

Scene Headings (Slugs): INT, EXT, and the Rest

The scene heading,often called a "slug line",is the line that tells the reader where and when we are. It's one of the first things a reader scans. Get it wrong, and you look like you've never read a script.

Basic Structure

The standard form is: INT. LOCATION - TIME or EXT. LOCATION - TIME. INT = interior, EXT = exterior. Sometimes you'll see INT./EXT. for a space that straddles both (e.g., a car with the window down). The location is a short, clear identifier: COFFEE SHOP, MARIA'S APARTMENT - BEDROOM, HIGHWAY 101. The time is usually DAY or NIGHT; you can use LATER, MOMENTS LATER, SAME, CONTINUOUS, or specific times (3:47 AM) when it matters.

Capitalization and Punctuation

Scene headings are written in ALL CAPS. No period at the end. The dash between location and time is typically a double hyphen (--) or an em dash; be consistent. Subheadings (e.g., MARIA'S APARTMENT - BEDROOM) use a space and a hyphen to separate the parent location from the sub-location.

CONTINUED and LATER

When a scene continues after a cutaway (we see another scene, then return), some formats use CONT'D at the top of the next page under the scene heading to indicate we're still in the same scene. In modern practice, many writers and producers have dropped "CONT'D" on scene headings in favor of "LATER" or "MOMENTS LATER" when there's a time shift, and nothing when the cut is immediate. Contests and studios differ: when in doubt, follow the style of produced scripts in your genre. The key is consistency within your script.

Slugs are also the backbone of production breakdowns. Every scene heading becomes a line item for scheduling and budgeting. Vague or inconsistent slugs ("SOME PLACE - DAY" vs. "INT. DINER - DAY") make the script harder to break down. Clear, consistent slugs make you look like you understand how scripts are used downstream.

Action, Character Names, Parentheticals, and Transitions

Below the slug comes the body of the scene: action lines (visual description of what we see and what characters do) and dialogue exchanges, along with a handful of supporting formatting elements that shape how the scene reads on the page.

Action Lines

Action is the narrative description of what we see and hear,what the camera would capture. It's written in sentence case, present tense, from the left margin (same as the slug) to the right margin of the action block (about 7.5"). Keep paragraphs short: two to four lines max. Large blocks of action suggest overwriting or a novelist's instinct; film scripts breathe in shorter beats. You can use CAPS for important sounds, key props, or the first introduction of a character name, but don't overdo it. One or two caps per paragraph is plenty.

Character Names

Before each line of dialogue, the character name appears in ALL CAPS, positioned centered on the page (or at the industry-standard character margin, typically 3.7" from the left edge). When the character is speaking off-screen (O.S.) or delivering voice-over narration (V.O.), that designation goes in parentheses immediately next to the name: MARIA (O.S.) or NARRATOR (V.O.). The abbreviation (O.S.) indicates off-screen presence; (V.O.) indicates voice-over. Whichever system you choose, apply it consistently throughout the entire screenplay.

Parentheticals

Parentheticals sit directly below the character name, nestled inside the dialogue column, and indicate manner of delivery or simultaneous physical action during the line: (whispering), (to Tom), (beat), (under her breath). Use them sparingly and only when they genuinely clarify intent. If the surrounding dialogue and action lines already convey the emotional tone or physical behavior clearly, skip the parenthetical altogether. Overuse of parentheticals reads as micromanagement—either distrust of the reader's comprehension or distrust of the actor's interpretive skill.

Transitions

Transitions (CUT TO:, FADE IN., FADE OUT., DISSOLVE TO:, MATCH CUT TO:, etc.) are traditionally right-aligned on the page. In contemporary screenplay practice, "CUT TO:" is frequently omitted altogether, since the default transition between scenes is understood to be a cut. "FADE IN." usually appears exactly once at the very beginning of the script; "FADE OUT." or "FADE TO BLACK." typically marks the end. When in doubt, err on the side of using fewer transitions; they become most conspicuous and distracting when overused.

Common Formatting Mistakes (And How to Avoid Them)

A few formatting errors show up again and again in amateur scripts, signaling inexperience to professional readers. Identify and fix these recurring mistakes, and you're already most of the way toward a clean, industry-standard presentation.

• Wrong font or size. Anything other than Courier/Courier Prime 12pt signals that you didn't bother to check. No exceptions for "it looks better in Georgia."
• Inconsistent slugs. Mixing "INT. COFFEE SHOP - DAY" with "Interior - Coffee Shop - Day" or "INT. COFFEE SHOP - DAY" and "INT. COFFEE SHOP - NIGHT" without a clear time break confuses readers and breakdown software.
• Dialogue that's too wide. Dialogue should sit in a column. If it stretches to the same width as action, the script looks like a novel.
• Centered character names that aren't. Character names should be consistently placed. Slight drift suggests manual formatting or copy-paste from another program.
• Missing or wrong (O.S.) / (V.O.). If we hear someone we don't see, or we hear a narrator, the designation matters for production. Omit it and the AD will have to guess.

Another common pitfall: relying too heavily on transition instructions. Typing "CUT TO:" after every single scene clutters the page and signals inexperience, because cutting is the assumed default transition in screenwriting. Reserve FADE IN. and FADE OUT. strictly for your script's opening and closing moments. When a page is littered with DISSOLVE TO: and SMASH CUT TO: notations throughout, it gives the impression of an early draft that hasn't been properly edited and streamlined.

The most efficient approach to sidestepping these formatting pitfalls is to compose your screenplay in dedicated software that automatically enforces industry conventions. This doesn't mean you can skip learning the underlying rules—you absolutely should internalize them. But once you've mastered the principles, delegating the mechanical tasks of margin spacing, typeface selection, and element positioning to your writing tool liberates you to concentrate on crafting compelling narrative. For an in-depth side-by-side analysis of how various screenwriting platforms handle both formatting precision and creative workflow, consult our detailed breakdown of Final Draft vs. 熙熙, where we transparently discuss the areas where established formatting tools still hold advantages and the aspects where contemporary tools eliminate repetitive busywork.

Letting the Tool Handle Format: Why It's Not Cheating

Certain screenwriters regard manual formatting as a point of pride or a demonstration of craft mastery. They'll painstakingly tab and space their way through an entire screenplay in Word or Google Docs, only to find themselves puzzled when their page count doesn't align with expectations or when a script reader mentions that the submission "felt structurally off" for reasons they can't articulate. The reality is that screenplay formatting is a problem the industry solved long ago. Specialized software has been executing it accurately for decades. The relevant question in 2026 isn't "is a program capable of formatting my script correctly?", but rather "which program delivers industry-correct formatting transparently, without demanding my attention, so I can channel my creative energy into developing solid structure and compelling story?"

熙熙 is engineered with industry-standard screenplay formatting as its foundational architecture. You select structural elements (scene heading, action, character, dialogue) or simply type in a manner the editor interprets, and the proper margins, typeface (Courier Prime 12pt), and positional placement are enforced automatically behind the scenes. There's no need to manually toggle font sizes or carefully nudge indentation values. You focus on writing; the script maintains correct appearance throughout. When you generate an FDX or PDF export for submission to producers or for production workflows, the output conforms precisely to what line producers and professional script readers anticipate receiving. This isn't a makeshift workaround or approximation—it's the identical formatting standard that tools like Celtx and Final Draft strive to deliver, with the significant distinction that 熙熙 simultaneously provides you with a Living Story Map, real-time structural visibility, and optional AI-assisted scene visualization capabilities. The result is industry-correct formatting combined with rich creative context and structural insight, rather than just a digital typewriter that knows margin placement.

Screenplay formatting that aligns seamlessly with production industry expectations, achieved without any manual margin adjustment or spacing tweaks.

If you're coming from a word processor or an app that doesn't enforce screenplay format, the shift to "the tool does it" can feel like losing control. You're not. You're gaining consistency. The only way to "lose" is to ship a script with wrong margins or the wrong font. Using software that guarantees correct format is the opposite of cheating,it's meeting the bar so your story can be judged on the page, not on the layout.

Mini-glossary: script writing meaning, format, and templates

Same Google box, three different people. On this site, every term below means film or TV screenplay, not cursive homework, not Arabic orthography, not a font meme.

Planner exports also mash in film script formatting, screenplay formatting, industry standard script format, and standard screenplay format, different adjectives, same job: margins, Courier (or Courier Prime) 12pt, element types a reader can scan in seconds. When vendors say "screenplay formatting software," they usually mean an app that enforces that grid so you do not fight Word for two hours. This guide is the spec; apps are the enforcement layer.

Script writing meaning. A timed grid: slugs, action, names, dialogue, transitions, roughly a minute a page so a line producer can squint and not feel lied to. Call it a script when it does that job.

Summary: Know the Rules, Then Choose Your Workflow

The Trench Warfare: What Beginners Get Wrong

The "Novelization" Trap（小说化陷阱）。初学者经常会在动作描写（action lines）部分写出密集的段落，详细描述房间里的每一件物品摆设，或者试图交代角色内心的思考过程、情绪变化的心理轨迹。这种写法会直接拖垮阅读节奏，让剧本在制作层面变得完全不可读——因为剧本的核心功能是为拍摄提供蓝图，而不是为读者提供文学体验。Fix: 将每段动作描写控制在 2-4 行以内，最多不超过四行。专注于我们能看到和听到的内容——镜头能捕捉的视觉信息和现场能录制的声音信息，而不是角色脑海中的独白或叙事者的全知视角。

The "Italic" Addiction（斜体成瘾）。在对白或动作描写中使用斜体来强调某个词或短语，是一种依赖拐杖的表现。如果文字本身的选择、节奏、上下文无法传递出那个重音或强调意图，那么斜体排版也拯救不了它——斜体不会让一句平庸的台词变得有力。Fix: 重新改写这句台词，通过用词选择、句式长短、前后呼应来营造更好的节奏感和自然重音。只在外语词汇、特定作品标题或极少数必须标注的专有名词时使用斜体。如果你发现自己频繁依赖斜体来

The "Parenthetical" Crutch. (angry), (sad), (sarcastically). If you have to tell the actor how to feel, the dialogue is failing. Fix: Trust the actor and the context. Use parentheticals only for action during a line or to clarify a non-obvious delivery (e.g., "to himself").

If the scene is written well, the actor doesn't need a parenthetical to know they're angry.

The "Transition" Overload. CUT TO: between every scene is noise. Fix: Delete them. The scene heading already implies a cut. Use transitions only for specific effects like SMASH CUT TO: or MATCH CUT TO:.

The "Font" Gamble. Some writers attempt to stand out by choosing what they consider a "prettier" or more sophisticated typeface—Helvetica, Times New Roman, or another general-purpose font. Fix: Resist that impulse entirely. Deviating from industry convention signals unfamiliarity with professional expectations rather than creative confidence. Stick exclusively to Courier Prime 12pt, the typeface readers and production teams expect to see on every spec script that crosses their desk.

Screenplay format in 2026 remains fundamentally unchanged in spirit and structure: Courier (or Courier Prime) 12pt, strict and specific margins, clear scene headings, and a consistent grid governing the placement of action blocks, character names, dialogue, and parentheticals. The one-page-per-minute convention continues to drive scheduling and production planning, and readers across the industry still expect scripts that look unmistakably like scripts—no deviation, no improvisation. The difference today is that you don't have to implement every one of these rules by hand or memorize every margin width. You can learn the principles once, as we've outlined here in detail, and then rely on dedicated screenwriting software to apply them accurately and automatically every single time you sit down to write.

Use this guide as a reference whenever you're unsure about a slug line, a margin setting, a transition cue, or any other formatting detail. Use it to spot-check and verify exports from any screenwriting tool, whether you're working in a new application or sharing a draft generated by someone else's setup. And when you're choosing or upgrading your screenwriting software for the first time or after years with another program, prefer tools that lock in correct, industry-standard format by default—so you can focus exclusively on what actually matters and what will make or break your script: story, structure, character, pacing, and the precise words on the page. The boring, unchanging rules are there for a very good reason: they free you to write. Your job is to satisfy them once, then forget about them completely and write.
