Comic Panel Builder
What Gutter Cutter does
Gutter Cutter is a comic panel builder that runs in your browser. A gutter is the gap between two panels. You draw the gutters and the panels are what’s left between them, so when you move or tilt a gutter, the panels on both sides of it change too.
Panel styles
American sets every gap to an eighth of an inch. Manga sets narrow gaps between the panels in a row and gaps three times as wide between the rows. Under Advanced you can set either gap by hand, or the width of one gutter.
Page sizes
Each size is a trim size, the size of the printed page: US comic (6.625 × 10.25 in), manga (5 × 7.5 in), digest (5.5 × 8.5 in), trade (6 × 9 in), 8 × 10 in and magazine (8.5 × 11 in). The dashed blue line is the trim edge. A panel that runs off the page goes an eighth of an inch past it, which is the bleed a printer asks for.
The download
Download PNG saves the page at 300 DPI with the bleed included. The file holds the panel borders on a transparent background, so it can sit as a layer over your art in a drawing app such as Clip Studio Paint. You don’t need an account, and your layout is kept in this browser.
The script for the page
Storyboon is a free editor for comic scripts: you type pages, panels and dialogue as plain text, and it formats them as a script while you type. There’s a guide to scripting a comic page layout too.
