How to Write a Play: Structure, Stage Directions, and Tools

Writing a novel is building a world inside the reader's head. Writing a play is something else entirely: it's giving text to bodies, in a space, in front of people.

This constraint changes everything. No internal narration, no panoramic description, no "he thought that." Everything goes through dialogue and stage directions. It's both more limited and more free than prose — because what the text lacks, the stage completes.

Here's how to structure, write, and finalize a play — whether it's your first or your tenth.

Structure: acts and scenes

The three-act structure

Most contemporary plays use a two or three-act structure. The five acts of classical tragedy (exposition, complication, crisis, reversal, denouement) are compressed today, but the principle remains:

Act I — Exposition: we discover the characters, the setting, the initial situation. The conflict takes shape. A dramatic question emerges: what's going to happen?

Act II — Conflict: tension rises. Characters face obstacles, dilemmas, reversals. This is the body of the play — where the audience holds its breath.

Act III — Resolution: the conflict resolves (or doesn't). The dramatic question finds its answer. The characters have changed — or refused to change.

Scenes

A scene begins when a character enters or exits. That's the classical rule, and it remains useful even if you break it: every entrance or exit changes the dynamic on stage.

A good scene has:

• An objective: what does the main character in the scene want?
• An obstacle: what prevents them from getting it?
• A change: the situation at the end of the scene differs from the beginning.

If a scene changes nothing about the state of the conflict, it's probably unnecessary.

Stage directions: less is more

Stage directions are the instructions in parentheses and italics that describe movements, set, tone, lighting.

A classic trap: writing too many. A play script isn't a film screenplay. The actor and director will interpret your text — that's their job. If you write "Marie stands up abruptly, knocks over her chair, turns toward the window, clenches her fists, and stifles a scream," you leave no room for interpretation.

What to indicate:

• Character entrances and exits
• Essential set elements (if the text isn't understandable without them)
• Significant pauses (A silence.)
• Actions that contradict the dialogue (she says "I'm fine" while crying)

What NOT to indicate:

• Emotions the dialogue already conveys
• Obvious actions ("he picks up the phone" when the dialogue is "Hello?")
• Detailed staging (that's the director's job)

Tennessee Williams was a master of poetic stage directions. In The Glass Menagerie, he writes stage directions that are almost lyrical prose — but they describe atmosphere, not gestures. Beckett, by contrast, was ultra-precise: in Endgame, every movement is choreographed. Both approaches work — but they're chosen, not accidental.

Giving each character a distinct voice

This is the central challenge of dramatic writing. In a novel, you can write "his vocabulary betrayed his modest origins." In theater, you must show it in every line.

Some concrete levers:

Sentence length: a nervous character speaks in short sentences. An intellectual uses long sentences with subordinate clauses. A shy person doesn't finish their sentences.

Vocabulary: a doctor and a mechanic don't describe the same pain with the same words. Language register (formal, standard, casual, slang) is your most powerful tool.

Verbal tics: a character who says "actually" every three lines, another who asks rhetorical questions, a third who never says "I." These language habits make a character immediately recognizable — even without reading the name before the line.

Subtext: what the character says isn't what they think. Arthur Miller excelled at this: in Death of a Salesman, Willy Loman talks about success throughout the entire play, but every line oozes failure. The audience hears both layers.

The read-aloud test

A novel is read in silence. A play is read — and especially performed — aloud. The simplest test to know if your dialogue works: read it aloud. If you stumble on a sentence, your actor will stumble too.

Better yet: have someone else read your text. You'll immediately hear the wrong notes — lines that are too long, artificial transitions, sentences nobody would actually say.

Standard formatting

The submission format for theater is codified:

• Character name: centered, in capitals
• Stage directions: italicized, in parentheses or indented
• Lines: below the character name, indented
• Acts and scenes: centered, in capitals (ACT I, SCENE 3)
• Font: Courier New 12pt (tradition) or Times New Roman 12pt
• Spacing: single for lines, double between characters

The dramatis personae (character list) appears at the beginning of the document with a brief description of each role.

How Extypis adapts to theater

Extypis isn't a dedicated screenwriting tool (like Final Draft). But several of its features directly address the needs of dramatic writing:

Act/scene structure: chapters become your acts, sheets become your scenes. Reorganize with drag & drop. The tree reflects your play's structure.

Character sheets: 8 types of narrative elements. For theater, character sheets are essential — voice, tics, relationships, arc. Access them in one click via @character mentions in the text.

Colored contextual notes: 6 note colors anchored to text. Create your own code: yellow for lighting, blue for movement, green for tone, pink for props. A dedicated view lists all your annotations.

Storyboard: kanban board to visualize your acts and scenes. Each scene is a card with summary and labels. See the complete structure at a glance.

Mention charts: who speaks in which scene? How many lines per character? Charts reveal imbalances — a secondary character who disappears during all of Act II, a protagonist who monopolizes Act III.

PDF export: via LaTeX, with quality typography. Stage directions, character names, and lines are correctly formatted.

Getting started

The best way to start a play isn't to start at the beginning. Start with the scene you see most clearly — the one that obsesses you, the one whose lines you hear in the shower.

Write that scene. Then ask yourself: what led to this moment? What follows from it? The preceding and following scenes will emerge naturally.

And if you're afraid of the blank page, remember what Tennessee Williams said:

"I try to work every day because you have no refuge but writing."

The stage is waiting. Enter.
