Planning a manga or webtoon but unsure how to map out your pages before drawing? A well-structured storyboard is the difference between a story that flows and one that confuses readers.

In this guide, you will learn how to create manga storyboards using AI tools, focusing on layout composition and pacing techniques that keep readers turning pages. We will also show you how creators on Mangaka have used these methods to bring their stories to life.

What Is a Manga Storyboard?

A manga storyboard (called a neme in Japanese) is a rough sketch-based plan that maps every panel across every page of a chapter. It shows:

  • Panel borders and sizes
  • Character positions and camera angles
  • Dialogue balloons and sound effects placement
  • The pacing rhythm — slow, tense, or fast-action beats

A storyboard is drawn before inking, so every creative decision is made cheaply, when erasing a panel costs nothing.

Why Pacing Is the Core Skill

Pacing in manga is controlled by panel count per page. More panels = faster pace. Fewer, larger panels = slower, more emotional or dramatic moments.

Classic pacing patterns:

Page typePanel countWhen to use
Action burst6–9 panelsFight scenes, chase sequences
Dialogue exchange4–6 panelsCharacter conversations
Emotional beat1–3 panelsReveals, shock, romance
Splash page1 panelChapter openings, climactic moments

Study how real Mangaka stories handle this. In I Was Reincarnated as the Villain?! , the isekai comedy uses quick multi-panel grids during comedic misunderstandings, then drops to a wide two-panel layout for dramatic reversals — a textbook pacing contrast that makes both tones hit harder.

Step-by-Step: Storyboarding with AI

Step 1 — Write the Scene Brief

Before drawing any panel, write two sentences per scene:

  1. What happens (the action or event)
  2. What the reader must feel (the emotion or tension)

Example:

Scene 7: The knight reveals she survived the ambush. Feel: shock, then relief.

This brief becomes your prompt when using an AI layout tool.

Step 2 — Plan Your Panel Grid on Paper (or Digitally)

Sketch a 6-panel grid on an A4 sheet or tablet. You do not need to draw characters — boxes and arrows are enough.

Mark:

  • Panel 1–2: Establishing shot (wide, sets the location)
  • Panel 3–4: Mid-shot dialogue or action
  • Panel 5: Reaction close-up
  • Panel 6: Transition or cliffhanger beat

For The Last Ember Knight , creators used this exact grid for the opening chapter — the wide establishing shot of a ruined kingdom, then quick cuts into the knight's face as she discovers the survivor.

Step 3 — Use AI to Generate Layout Variations

With your scene brief written, feed it to an AI layout assistant (like those built into Mangaka ) with a prompt such as:

"Generate a 6-panel manga page layout for: a knight discovers a survivor in a burning village. Emotional tone: shock then determination. Include one wide establishing shot and one close-up reaction panel."

The AI will output panel arrangement options. Compare at least two variations before picking one — AI layout suggestions are starting points, not final answers.

Step 4 — Add Dialogue Balloons to the Storyboard

Dialogue placement affects panel flow. The eye follows balloons in reading order (right-to-left for traditional manga, left-to-right for webtoon/manhwa style). Place balloons before finalising panel sizes — a balloon that is too large forces you to shrink the artwork.

Rule of thumb: no more than 30–40 words per panel if it contains action. Dialogue-heavy panels can carry 60–80 words if there is minimal background art.

Step 5 — Review Pacing with the "Thumb Test"

Flip through your storyboard thumbnails rapidly, like a reader who is skimming. Notice:

  • Where does your eye speed up?
  • Where does it slow down?
  • Is there a payoff panel after a build-up?

Adjust panel count per page based on what you feel, not just what you planned. In My Boyfriend Meows Now , the rom-com uses a recurring "pause panel" — a single wide panel with no dialogue — after each comedic beat. That pause is what gives the joke time to land.

Common Storyboarding Mistakes

Mistake 1: All panels the same size A uniform grid feels flat. Vary panel sizes to signal importance: biggest panel = most important moment.

Mistake 2: Skipping the storyboard for "simple" chapters Even a conversation chapter needs a storyboard. Without it, you end up with talking-heads pages that lose readers.

Mistake 3: Too many panels per page Nine panels per page is rarely readable on mobile. Keep action pages at 6–7 panels maximum for webtoon format.

Mistake 4: Not planning the chapter end The last panel of a chapter determines whether a reader clicks "next chapter." Plan it first, then work backwards.

AI-Specific Tips for Manga Storyboarding

  • Use AI for reference, not authority. AI layout tools suggest; you decide.
  • Batch your prompts. Generate storyboards for all 10 pages of a chapter in one session, then review as a whole.
  • Combine AI layout with traditional thumbnail sketches. Hand-drawn thumbnails catch spatial problems AI misses.
  • Check for character consistency. If you use AI-generated panel art in your storyboard references, verify characters look the same across panels.

With Mangaka , you can generate character references, panel art, and even full chapters from a structured storyboard — the platform reads your scene briefs and produces consistent artwork across an entire episode.

Summary

StepAction
1Write scene briefs (what + feel)
2Sketch a rough panel grid
3Use AI to generate layout variations
4Place dialogue balloons before finalising panel sizes
5Do the thumb test and adjust pacing

A storyboard takes 30–60 minutes per chapter for an experienced creator. The time saved in revision and redrawing far exceeds that investment. Start with one page, practise the thumb test, and build from there.

Frequently Asked Questions

What is a manga storyboard called in Japanese?
A manga storyboard is called a neme (ネーム) in Japanese. It is a rough sketch-based plan that maps panels, dialogue, and camera angles before inking begins.
How many panels should a manga page have?
For action scenes, 6–9 panels per page is common. For emotional beats or splash pages, 1–3 panels works best. Webtoon/mobile formats should stay under 7 panels per page for readability.
Can I create a manga storyboard with AI?
Yes. Write a scene brief (what happens + what the reader should feel), then use an AI layout tool like Mangaka to generate panel arrangement options. Always review and adjust AI suggestions before finalising.
What is the thumb test for manga pacing?
The thumb test means flipping through your storyboard thumbnails quickly, like a skimming reader. It reveals where pacing speeds up or slows down and whether payoff panels land correctly after build-up sequences.
How long does it take to storyboard a manga chapter?
For an experienced creator, one manga chapter (10–20 pages) takes 30–60 minutes to storyboard. Beginners may need 1–2 hours. The investment saves significant redrawing time later.
