Scriptwriting Format: Conventions of Writing for Performance
Learn the professional conventions of script format, including stage directions, dialogue layout, and act/scene structure, and apply them to a fully original scripted extract.
A script is a blueprint for performance, not a finished story. When you write a script, you are writing instructions for actors, directors, and designers as much as you are writing dialogue. Every choice in a script's layout exists to make the text usable on a stage, not just readable on a page.
This matters for Criterion B (Organizing) especially: a script that is organised according to its format conventions signals to a reader that you understand the purpose and audience imperatives of dramatic writing -- actors need clear cues, directors need staging information, and readers of the script (rather than viewers of the performance) need enough detail to imagine the scene.
The instructions in a script (other than the words a character speaks) that tell actors how to move, feel, or deliver a line, or that describe the setting. Written in a different style from dialogue -- usually in the present tense, in brackets or italics, and kept concise.
A major division of a play, often marking a significant shift in time, location, or dramatic movement. Acts are usually divided into smaller units called scenes, each set in one place at one continuous time.
Power dynamics expressed through dialogue (who interrupts whom, who commands, who deflects) are covered fully in this unit's node "Power dynamics in dialogue." Here, focus only on how to format dialogue and stage directions correctly -- not on analysing what the dialogue reveals about relationships.
- Title and setting note: name the play/scene, then a brief stage direction establishing time and place before any dialogue begins.
- Character list (for longer scripts): list character names once at the top if the cast is large, so a director can cast the piece at a glance.
- Character name in capitals (or bold), followed by a colon or line break, then their line of dialogue -- kept visually separate from stage directions.
- Stage directions in brackets or italics, kept brief and only including what is essential for staging (movement, tone, a key prop, an entrance or exit).
- Dialogue exchanges built in short, speakable lines -- avoid long unbroken paragraphs of speech unless the moment calls for a monologue.
- Scene/act breaks marked clearly (e.g. "END OF SCENE ONE") whenever time, place, or major dramatic focus shifts.
A correctly formatted scripted extract
- SCENE ONE. A cramped office. Late afternoon light through a dusty blind. A desk covered in unopened letters.
- MARGUERITE: (not looking up from the desk) You're late.
- DEVLIN: (still in the doorway, coat dripping) The trains again.
- MARGUERITE: The trains again. Always the trains.
- DEVLIN: (crossing to the desk, dropping a folder onto it) I brought the contract.
- MARGUERITE: (finally looking up) You didn't sign it.
- DEVLIN: I didn't say I would.
- END OF SCENE ONE.
Notice what the worked example does. The opening stage direction sets place and mood in one economical sentence -- it does not describe what characters are thinking, only what can be seen or heard. Each character cue (MARGUERITE, DEVLIN) is visually distinct from the line that follows it, so an actor scanning the page can find their part instantly. The bracketed directions are short: "(not looking up from the desk)" tells an actor exactly what to do without dictating every emotional nuance -- that interpretive work belongs to the actor and director, not the script. Finally, the scene marker ("END OF SCENE ONE") gives a clean structural break, useful for Criterion B when a reader is following the shape of a longer piece.
- Have I clearly separated stage directions from dialogue (brackets, italics, or a distinct line)?
- Is each character's name presented consistently so a reader can track who is speaking at a glance?
- Are my stage directions concise -- describing only what can be staged, seen, or heard, not internal thoughts?
- Have I marked scene or act breaks wherever time, place, or dramatic focus shifts?
- Do my dialogue lines sound speakable out loud, rather than reading like narrated prose?
- Have I avoided long unbroken blocks of stage direction that would slow down a live reading?
- Stage directions describe what can be staged (movement, tone, setting) -- never a character's private thoughts.
- Character cues (name + colon, or capitalised name) must be visually distinct from dialogue every time.
- Scene and act breaks mark shifts in time, place, or dramatic focus -- label them clearly.
- Dialogue should sound speakable: short, natural lines rather than paragraph-length narrated prose.
- Script format itself is an Organizing (Criterion B) skill -- format signals purpose and audience to a director or actor.
