In today’s article, we’ll guide you through the fundamentals of script formatting, the pitfalls you need to be avoiding, and all the tools you’ll need to streamline your formatting process.

You should then have a solid grasp of how to present your screenplay to meet the ever-demanding industry standards of the film and television world.

FAQ: What is a screenplay?

Put simply, a screenplay is a 90-120 page document, typed in Courier 12pt font on 8.5″ x 11″ white paper with three holes. One page in Courier font roughly equals one minute of screen time. This helps writers gauge the duration and pacing of their story for a better writing and viewing experience.

Why Formatting Matters in Screenwriting

Formatting is so often talked about in screenwriting circles, but just why is it so important?

Firstly, a screenplay isn’t just about storytelling; it’s a blueprint for production. Directors, actors, cinematographers, and editors all rely on the script’s format to interpret scenes efficiently. Film and television production demands clear timescales, budgets, and logistics so to have everyone on the same page with a formatted script is invaluable.

A script must be understood by an entire production crew. Industry-standard formatting ensures that all scripts are easy to read and understand. Over the years, this has become an expectation from executives and producers to receive properly formatted scripts. Anything less can lead to immediate rejection.

By adhering to the conventions of script formatting, you as a screenwriter demonstrate that you’re serious about your craft and are ready to work within the industry.

Basics of Screenplay Format

We’ve already talked a lot about formatting expectations so let’s explore what they actually are. Screenplays follow a standardized format that is essential for industry professionals. Here are the core components:

Scene Headings (Sluglines)

Scene headings (also known as sluglines) indicate the location and time of a scene. They are always written in uppercase and follow this format.

INT/EXT. LOCATION – TIME OF DAY

Start by indicating whether the scene is interior (INT) or exterior (EXT), before moving onto the location and time of day.

INT. COFFEE SHOP – DAY

EXT. PARKING LOT – NIGHT

If a scene transitions between locations, you can use INT/EXT. and vice versa.

Action

Action lines describe what is happening in the scene. They should be concise, written in the present tense, and avoid excessive descriptive detail.

Good action descriptions focus on what can be seen and heard.

John enters the dimly lit room, scanning for any signs of movement. A chair creaks in the corner. He reaches for his gun.

Avoid over flowery prose or internal thoughts that cannot be visualized on screen. For more tips, check out our blog on how to write action lines that make your script move.

Dialogue

Dialogue follows the character’s name, which is centered and written in uppercase. The dialogue itself is placed beneath it, indented from both margins.

Let’s see how this is mapped out on a script:

Notice how we’ve used a parenthetical just before the dialogue. Use these sparingly to indicate tone or small actions. However, make sure to only use them when necessary.

Transitions

While many modern screenplays avoid explicit transitions, they can still be used when necessary.

CUT TO: indicates a direct cut to another scene.

FADE IN:/FADE OUT: is used at the beginning or end of a screenplay.

DISSOLVE TO: indicates a passage of time or a change in tone.

Transitions are always aligned to the right margin of the page, like this:

Formatting Rules

Alongside the screenplay elements detailed above, there are rules on how these should be presented on the page.

Always use 12-point Courier Font.
1-inch margins on all sides, with a 1.5-inch margin on the left for binding.
Single-spaced lines for action and descriptions. Double-spaced between scene headings, action and dialogue.
In terms of page length, a feature script is typically between 90 and 120 pages, with one page roughly equating to one minute of screen time.

Now we’ve covered all the building blocks of a screenplay, let’s look at everything in action. Here’s the opening page of The Lego Movie (2014).

Common Script Formatting Mistakes and How to Fix Them

Many beginner screenwriters (and some experienced ones!) make formatting errors that can harm their script’s readability and professional appeal. Here are some common mistakes and how to fix them:

Overwriting Action Descriptions

Keep action lines concise and visual and avoid long paragraphs with unnecessary detail.

Which one of these action line examples do you feel is most effective?

This:

John walks slowly into the room, hesitating before cautiously reaching for the doorknob, his breath quickening as he anticipates what might be on the other side.

Or this:

John hesitates, then grips the doorknob. He exhales sharply before stepping inside.

Both examples depict the same scene, however example one would be best suited for a novel. The second example is more visual and is more at home in a screenplay.

Incorrect Dialogue Formatting

Ensure character names are in uppercase, and dialogue is properly indented. Avoid excessive parentheticals or unnecessary dialogue tags.

For instance, instead of writing:

An example of dialogue in a screenplay written with celtx screenwriting software. The example is incorrect.

Simply write:

An example of properly formatted dialogue in a screenplay, written with Celtx.

Ultimately, don’t overcomplicate things or feel you need to describe actions and dialogue in huge detail. Focus on visuals!

Excessive Use of Camera Directions

Let the director and cinematographer handle shot selection unless it’s necessary for storytelling. Instead, hone in on the visual impact of a moment through action.

So, instead of writing:

Camera zooms in on Sarah’s face.

Why not try:

Sarah’s eyes widen. Her breath catches.

The second action line doesn’t mention a camera at all, yet we know that Sarah’s eyes in this moment are important as the writer has highlighted it.

Mixing Tenses

Always write in the present tense. A common mistake is a shift between past and present. Avoid writing action lines such as:

John walked into the room and looks around.

Instead, maintain present tense:

John walks into the room and looks around.

Improper Scene Headings

Ensure your sluglines are formatted correctly, clearly stating the location and time of day. Keep your headings specific and consistent all the way through your script, avoiding examples like this:

SOMEWHERE IN THE FOREST – NIGHT

Instead:

EXT. DENSE FOREST – NIGHT

Too Many Parentheticals

Yes, parentheticals can be helpful in determining the tone or specifics of a line of dialogue. However, excessive parentheticals clutter the page and ultimately slow down the read.

Use them when needed, like when you’re indicating sarcasm, whispering or direct actions that impact a line’s delivery.

Overuse of Capitalization

Reserve capitalization for character introductions, major sound effects, and significant visual cues. Writing:

JOHN SLAMS THE DOOR SHUT AND STARTS SCREAMING could be jarring.

Instead, highlight only essential elements:

John slams the door shut. He SCREAMS.

Here, the scream is what stands out, drawing our eyes to it, and making his scream the focal point of the line.

Ignoring Page Length Guidelines

While creativity is of course, extremely important, script should generally adhere to industry-standard length.

A 150-page screenplay for a drama will likely need to be trimmed or be passed over by an executive, whereas a 60-page feature script may be deemed too short.

Bear in mind the page length guidelines based on the project you’re writing.
