Screenplays are a unique and often challenging medium for storytelling because they are essentially stories on the page made for the screen. It can be difficult for screenwriters to communicate the visuals of a film through screenwriting, but one of the best tools they have to do this is the slug line. They are used in various ways to communicate effectively and efficiently to the reader. Let’s examine how to write sluglines into a screenplay.

Master scene headings
Before learning how to write sluglines, you must first understand the slugline definition. What is a slug line? Check out our previous article that analyzes what a slug line is and how they are used.
Once you’ve got a solid understanding of the slugline definition, let’s talk about how to write them in a screenplay.
The master scene heading is one of the most fundamental slug lines when formatting a screenplay. It is responsible for starting a scene and establishing the location and time of a scene. The master scene heading, like all other slug lines, is written in all caps beginning on the left margin of the page.
The master scene heading is unique from other slug lines, in that it has its own structure when it comes to format. Let’s take a look at how to write sluglines using StudioBinder’s screenwriting software.
In a new screenplay project, start by selecting the “Scene Setting” icon. This will create a line on your script with the correct format for a master heading.
Next, you will clarify whether the scene is happening inside (INT.) or outside (EXT.). If the scene moves from inside to outside you would enter “INT/EXT.” If your scene moves from outside to inside you would use “EXT/INT.”
Next, type the specific location where the scene take’s place. This may be someone’s house, a restaurant, a park, etc.
Finally, you will insert a dash followed by the time of day during which this scene is taking place. This can be day, night, morning, evening, etc. The StudioBinder screenwriting app has presets for you to choose from.
All of your slug line script headings should end up looking similar to this.

Master screenplay scene headings are undoubtedly the most used and most fundamental of slug lines. But sometimes you need to call attention to a story element mid-scene. Let’s dive into how to write sluglines using subheaders.
How to write sluglines mid-scene
Once the master scene heading is established, screenwriters often use subheader slug lines to draw attention to a specific scene element, important detail, or simply to break up a longer scene.
Subheader slug lines can be used for a location change within a master location, visual directions such as a specific shot, or character names during action descriptions and sequences. No matter what type of subheader it is, they should be formatted the same.
Each subheader slug line should be written on their own line in the screenplay in all uppercase letters.
This is frequently used when characters move room to room within a house. Here are some examples of how to write sluglines as a subheader.
To create your subheader slug line, first create a new line of action description by selecting the “Action” logo on the top toolbar.
Proceed by writing out the slug line in all uppercase letters.
Other times screenwriters utilize subheadings to communicate the passing of a short amount of time.
These slug line examples show the difference between subheadings and master scene headings is that a master scene heading begins a scene by establishing the location and time of a scene. A subheading, on the other hand, draws attention to a change in time or location within a scene.
Slug lines are helpful because they help the flow of a scene for a reader and can break up longer segments of a script that can keep a screenplay from becoming incredibly dense.
It is always important for screenwriters to keep in mind that a screenplay is not a novel. Screenplays are supposed to be written for the screen and thus the writing of a screenplay should serve this.
Using slug lines is essential to communicate visual elements of a screenplay and how they will appear on screen.

One of the most critical elements of a screenplay is a story’s characters. Learn how to most effectively introduce characters in your screenplay in our next article.
