How to Make Comic Panels in PaintTool SAI: An Expert‘s Guide
Are you an aspiring digital comic artist looking to bring your stories to life? With the explosive growth of webcomics and digital graphic novels, there‘s never been a better time to start creating. In fact, according to a 2022 survey by GraphicNovel.net, 63% of comics are now read digitally. To tap into this booming market, one of the first and most crucial skills you‘ll need to develop is paneling—the art of composing your story into a sequence of frames.
As a professional illustrator with a BFA in Sequential Art and over 7 years of experience using PaintTool SAI, I‘ve published multiple popular webtoon series across genres like fantasy, sci-fi, and slice-of-life. And I‘m thrilled to share my go-to techniques for crafting comic panels in this powerful digital art software.
In this comprehensive guide, you‘ll learn three simple yet versatile methods for making and editing comic panels in SAI:
- Using the Two-Point Perspective Grid for classic panel grids
- Creating stylized panel borders with the Layer > Outline function
- Sketching freehand panels with the Straight Line tool
Whether you want to create traditional comic strip layouts, add unique framing flourishes, or draft organic panel compositions, these techniques will give you the foundation to bring your sequential art visions to life. Let‘s dive in!
Method 1: Construct Precise Panel Grids with the Two-Point Perspective Tool
Traditional comic books and strips often feature uniform rectangular panels arranged in a grid. Did you know a typical comic page contains 5-9 panels? While SAI doesn‘t have a built-in comic panel tool like some other programs, we can use the Two-Point Perspective Grid ruler to create precise, customizable panel layouts. Here‘s how:
Step 1: Create a new canvas in PaintTool SAI. In the Layer window, click the Grid ruler icon (it looks like a triangle) and select "New 2 VP Perspective Grid."

Step 2: The perspective grid will appear on your canvas. To align it perfectly, hold the Ctrl key while dragging the corners to snap the grid to your canvas edges.

Step 3: Right-click the grid layer and choose "Property." This opens the Grid Ruler dialog, where you can slice the grid into panels. Input your desired number of divisions for the G and B axes—the more divisions, the more panels! For a classic 3×3 panel grid, enter 15 for both axes.

Pro Tip: Use the Interval slider to adjust your grid‘s vanishing points and create more or less exaggerated perspective!
Step 4: Next, let‘s set up SAI to snap our lines to the grid. Go to View > Snap and choose "Line." Now your lines will automatically align to the nearest grid intersection, making it easy to trace your panel borders.

Step 5: On a new layer, select the Pencil or Brush tool, choose black from the color picker, and set your desired line thickness. Now simply trace along the grid lines to draw your panel frames. Feel free to hold Shift while drawing to snap to perfect 90 degree angles.

Step 6: Once you‘re happy with your panels, click the eye icon on the grid layer to hide it. Voila! You now have a perfectly precise comic panel layout ready for your art.

Pro Tip: Save custom panel templates as SAI files so you can easily reuse your go-to layouts. Great for comic strips and multi-page projects!
By using the 2 VP Perspective Grid, you can create infinitely customizable panel grids with just a few clicks. Experiment with different division and perspective settings to find your ideal layouts.
Method 2: Add Unique Framing Flourishes with the Layer > Outline Function
Want to give your hand-drawn panels some extra oomph? SAI‘s Layer > Outline function is a fantastic tool for adding weight, style and polish to your panel borders. Here‘s a quick overview of how to use it:
Step 1: Begin with your comic panels sketched or inked on a layer (or several layers). Use the Select tool to highlight the layer(s) you want to outline.

Step 2: Go to Layer > Outline to bring up the Outline dialog box. This handy menu lets you customize your outlines in several ways:
Outline dialog box" />
- Width: Controls the thickness of your outline. A setting of 5-20 pixels works well for most comics.
- Position: Applies the outline inside, centered on, or outside your artwork. For panel borders, choose "Outside" to prevent obscuring your lineart.
- Apply to Canvas Edges: Outlines your entire canvas. Great for cover art and splash pages!
- Update Preview: Shows a live preview of your outline as you tweak the settings.
Pro Tip: Outline in stages, starting thin and gradually increasing Width, to create a bold, multi-stroke effect!
Step 3: Once you‘ve dialed in your preferred settings (I usually start with Width 10 and Position Outside), click OK to apply the outline. Repeat for each panel layer. You can also Group your panel layers first to outline them all at once.

The beauty of the Layer > Outline function is its flexibility. By varying line weight and position, you can create all kinds of panel border styles, from delicate frames to chunky, cartoony outlines. It‘s also a great way to make important moments pop or stylize flashbacks and dream sequences. Don‘t be afraid to get creative!
| Outline Position | Outline Width | Example |
|---|---|---|
| Outside | 5-10px | ![]() |
| Outside | 20-30px | ![]() |
| Outside | 5-20px, gradual | ![]() |
| Inside | 2-5px | ![]() |
As you can see, applying outlines to your panel borders is a quick, stylish way to level up your comic pages and make your layouts more dynamic. I use this technique in almost every comic I create—it‘s a game-changer!
Method 3: Sketch Organic Layouts with the Straight Line Tool
Sometimes you want your panel composition to have a more freeform, hand-drawn look. That‘s where the Straight Line tool comes in! This simple but mighty tool is perfect for drafting fresh panel layouts before refining your lineart. Let‘s look at how to rough out a custom paneling scheme in SAI:
Step 1: Create a new layer and select the Straight Line tool from the Toolbar (or hit the X key).

Step 2: Before you start drawing, go to View > Snap and make sure "None" is selected. You want to be able to draw your panels freely without snapping to a grid.

Step 3: Now you can start sketching your panel layout! Click and drag to draw straight lines. If you want to constrain your lines to perfect 45 or 90 degree angles, hold the Shift key as you draw.

Pro Tip: To create panels within panels, try this: Draw your main panels normally, then switch to a colored Pencil or Brush and loosely block in your desired sub-panels. Use these guides to draw your detail panel borders with the Straight Line tool. It‘s a fun way to add depth to your compositions!

Step 4: Continue drawing panels until you‘re satisfied with your layout. At any point, you can adjust your lines by clicking and dragging the end points.

Step 5: When you‘re happy with your freehand panel composition, create a new layer and trace over your sketch lines with a clean black line (a pixel art brush works great for this).

And there you have it—a totally unique, organic panel layout ready for your comic art and lettering! The Straight Line tool is ideal for planning pages with diagonal panels, uneven grids, circles, and other irregular shapes. It‘s a lifesaver when you want to break out of the grid and experiment with fresh storytelling techniques.
Closing Thoughts: Experiment to Find Your Signature Style
In this guide, we‘ve explored three versatile methods for crafting comic panels in PaintTool SAI:
- Using the 2 VP Perspective Grid for precise, uniform panel layouts
- Applying the Layer > Outline function to create bold, stylized panel borders
- Sketching freeform panels with the Straight Line tool
Each of these techniques has its strengths. The perspective grid is perfect for classic comic strip layouts, panel outlines add instant polish and flair, and freehand sketching allows for dynamic, out-of-the-box compositions.
But remember: There are no hard and fast rules for paneling! The most effective comic layouts combine multiple techniques to guide the reader‘s eye and convey the story in a unique way.
Here are a few parting tips to help you take your paneling to the next level:
- Plan your panels in thumbnails before touching your drawing software. This helps you visualize your page composition and pacing.
- Vary your panel shapes and sizes to control the flow and rhythm of your story. Large, wide panels create a sense of scale, while small panels speed up time and build tension.
- Use diagonal and overlapping panels to add depth and dynamic energy to your pages.
- Don‘t be afraid of negative space! A well-placed gap between panels can speak volumes.
- Above all, trust your intuition and keep practicing. Developing your eye for paneling takes time, but it‘s a skill that will benefit every aspect of your visual storytelling.
So go forth and panel with confidence, my fellow artists! Dive into SAI and experiment with these techniques. Combine them, push their boundaries, and make them your own. With dedication and practice, you‘ll be on your way to crafting professional, engaging panel layouts that bring your sequential art to life.
