How to Write a Comic Script (With a Full Sample Page)

A comic script is a set of instructions for other people. Your artist reads it to know what to draw, your letterer to know what words go where, and your editor to see whether the story works before anyone spends a week on inks. Prose writers often write scripts that read beautifully and draw terribly. This guide covers the format, the rules of thumb that keep pages drawable, and one complete sample page with notes on every choice.

Full script vs plot-first

Full script means you break the story into pages and panels, describe each panel, and write every line of dialogue, caption and sound effect before the artist starts. It is a common default for collaborative work because it makes page count, word count and pacing visible early.

Plot-first, often called the Marvel method, means you write a plot breakdown (sometimes page by page, sometimes looser), the artist draws the pages from it, and then you write the dialogue to fit the finished art. It gives the artist more room to stage scenes. The cost is less control over space for words: a page can come back with no room for the line that explains the twist.

If you are new, or working with an artist for the first time, write full script. If you draw your own book, a thumbnailed plot with dialogue notes may be enough.

Format basics

There is no single standard comic script format the way there is for screenplays, and layouts vary by publisher and writer. What matters is consistency. A clean format includes:

Page headings in caps: PAGE ONE, PAGE TWO. Adding the panel count, like PAGE SEVEN (six panels), helps the artist plan at a glance.
Panel numbers that restart on every page: PANEL 1, PANEL 2. Then "page 12, panel 4" points to exactly one place.
Panel descriptions in plain present tense prose.
Lettering lines below each description, each tagged by type: the character name for dialogue, CAPTION for narration boxes, SFX for sound effects.
Balloon modifiers in parentheses when needed: (OFF) for off-panel speakers, (WHISPER), (SMALL), (RADIO), (THOUGHT).

Panel descriptions an artist can draw

The most important rule: one moment per panel. A panel is a single frozen instant. "Mara picks up the key, turns it, and throws it across the room" is three panels, or one panel and two problems. If a description contains "then" or "as she," check for a second action.

Other habits that make descriptions drawable:

Start with the shot. Give the camera distance first (wide, medium, close) so the artist knows the scale before the details.
Describe what can be seen. "She remembers her mother" cannot be drawn. "She holds her mother's watch, not looking at it" can.
Name every character in the panel, even if they were there last panel. The artist may draw panels out of order.
Introduce characters once with a short visual tag (age, one clothing detail, one posture note) and keep a separate character reference for the rest.
Keep it short. Two to four sentences is a good target.
Order speakers left to right. Whoever speaks first should usually be placed on the left so the balloons read in order.

Dialogue, captions and SFX

Each lettering line is one balloon or one box. If a character says two things with a pause between, give them two lines; the letterer will usually make two connected balloons.

Captions carry narration, inner voice, or location and time stamps. SFX lines name the sound; the artist or letterer decides how it looks. Keep SFX to sounds that matter.

For more on how these words land on the art, see comic lettering basics for balloons, captions and SFX.

Word budgets: rules of thumb

Overwritten pages are a very common problem in first scripts. These rough guidelines vary by publisher, genre and page size:

About 25 words or fewer per balloon. Longer than that and the balloon starts to cover the art.
Two or three balloons per panel, at most. A panel with five balloons is usually two panels.
Roughly 200 words or fewer per page for a dialogue-heavy page, and far fewer for action.
Six panels or fewer per page is a comfortable default. Each extra panel shrinks the space for art and words.

Count your words before you send the script. If a page is over budget, cut adjectives, merge balloons, or move a line to the next page.

Page turns and reveals

In a Western print comic, page one is usually a right-hand page, so odd-numbered pages sit on the right and even-numbered pages on the left. The reader sees both pages of a spread at once, but not the next spread until they turn.

That gives you a rule: put surprises at the top of even-numbered pages. End the odd page on a question, a door opening, or a character's shocked face, and pay it off after the turn. A reveal on the same spread as its setup gets spotted early. The guide to comic panel layouts and pacing covers this in more depth, along with splashes and spreads.

Notes to the artist

Good notes explain why something matters: "Keep the hand small and easy to miss; the reader should only notice it on a second look." Bad notes dictate exact camera angles for every panel when the artist could solve it better.

Put general notes (tone, references, recurring locations) at the top of the script, and panel-specific notes inside the panel, clearly marked. If the artist suggests a better staging, take it.

A complete sample page

Here is one full page from an invented horror story called Gull Rock, about a girl named Mara who helps her father keep a remote lighthouse. It is page seven, a right-hand page, so the final panel leads into a page turn.

PAGE SEVEN (six panels)

PANEL 1
Wide establishing shot. The lighthouse on Gull Rock at dusk, seen from the
water. Heavy swell. One lit window near the top of the tower. A small
rowboat is tied at the jetty below.

CAPTION: Gull Rock. The night the lamp failed.

PANEL 2
Interior, the lamp room. MARA (14, oilskin coat too big for her, hair tied
back) kneels beside the great lens, holding a hand lamp. The lens mechanism
is still. Her father's toolbag lies open beside her.

MARA: It's not the wick.
MARA: Dad, the clockwork's stopped.

PANEL 3
Same angle, slightly wider. From the stairwell door behind Mara, the shadow
of her father, TOMAS, falls across the floor. We do not see him.

TOMAS (OFF): Then wind it.

PANEL 4
Close on Mara's hands on the brass winding key. Knuckles white. The key will
not turn.

SFX: KRRK

PANEL 5
Medium shot. Mara has pulled a cloth off the clockwork housing. Wedged
between two gears is a hand made of wet seaweed and shell, its fingers
curled around a gear tooth. Note: keep the hand small and in shadow. Mara
has not understood what she is looking at yet.

MARA (SMALL): ...Dad?

PANEL 6
Mara turns toward the stairwell door, lamp raised. The door is open. The
stairwell beyond is dark and empty. Water drips from the top step.

NO DIALOGUE

Why each choice was made

Panel 1 is the only wide shot on the page. It establishes place and mood, and the caption gives location and a hint of trouble in seven words. It goes at the top because the reader needs orientation before the action starts.

Panel 2 introduces Mara with three visual tags: age, a too-big coat (she is doing an adult's job), and the hair. It has two balloons because she pauses between the observation and the call for help. Total: eight words.

Panel 3 keeps the same angle so the only thing that changes is the shadow. The voice is tagged (OFF) so the letterer points the tail to the door, not to a visible figure. Three words.

Panel 4 is a close-up and a single action: the key not turning. The SFX is the only lettering. Short panels like this speed up the read.

Panel 5 is the discovery, but underplayed. The note tells the artist why the hand should be small: the horror is that Mara has not processed it, and the reader may not have either. The (SMALL) modifier asks for a small balloon or small lettering to match her quiet voice.

Panel 6 is silent on purpose. If her father was on the stairs, where is he? The empty stairwell and the dripping water recast the voice in panel 3, and the reader turns the page to find out. Because page seven is a right-hand page, whatever waits on page eight stays hidden until the turn.

The whole page carries 19 words of dialogue and caption, plus one sound effect, well under any page budget.

Common mistakes and fixes

Camera moves inside a panel. "We pan across the room" cannot happen in a still image. Split it into panels or pick one frame.
Dialogue that describes the art. If the panel shows the door is open, nobody needs to say "the door is open."
Unclear speakers. Every dialogue line needs a name, and every off-panel speaker needs (OFF).
Reveals on the wrong side. Check the page number of every big surprise.
Prose habits. "She feels" lines and backstory belong in captions, if anywhere.

If you are bringing an existing prose story into comics, adapting a novel into a comic, screenplay or game walks through deciding what to cut and what to show.

Writing comic scripts in Aevon

Aevon's Comic Studio is built around the script and the page at the same time. You write the script and lay out pages with panel layouts, and the two stay in sync, so you are not reconciling a script document against a separate layout file.

Once art exists, you place images into panels and add lettering balloons for speech, thought and captions directly on the page. Comic Studio also offers pacing suggestions. The guided read mode steps through panels one at a time, which is a quick way to check that panel 6 of a page like the sample above actually reads as a beat.

Your character references, location notes and lore live in the same project, and the asset library holds concept art and reference images for your artist. If you started the story as a novel, you can convert the project to a Comic at any time without losing anything. When the book is ready, Comic Studio exports to PDF, CBZ and a vertical webtoon strip. Aevon is free, and runs on the web, macOS, Windows and Android.
