Plan comic panel grids and measure every panel to the millimetre
This app is a layout tool for comic and graphic novel pages. It lays out a page's panel grid and computes the exact width, height and gutter of every single panel, expressed in millimetres, inches or pixels for the page format and print DPI you choose. Instead of guessing at proportions or recalculating by hand each time a gutter changes, you get measured figures you can take straight to the drawing board or to your art software.
You begin in Setup, where you pick the page format, the unit you prefer to work in and the print DPI. From there the page is built in tiers: add a tier, then tap 1 to 4 to split it into that many panels. Build the stack of tiers upwards until the page reads the way you want it to. The structure stays editable, so a page can be reorganised as the storytelling demands rather than being locked in by the first arrangement you tried.
Gutter and margin sliders drive a live preview that reflows as you move them, showing trim, bleed and safe areas together. Because the three zones are drawn at once, it is easy to see when a panel edge is creeping towards the trim, when a gutter has grown wide enough to break the rhythm of the tier, or when the margins have squeezed the artwork more than intended. Every adjustment is reflected immediately, so the geometry of the page is something you watch rather than something you work out afterwards.
Alongside the preview, a live table lists the measured width and height of each panel in your chosen unit. That table is the heart of the tool: it turns a visual arrangement into concrete numbers for ruling up boards, setting canvas sizes or briefing a collaborator. Switch the unit or the print DPI and the figures are recomputed for the new context, which makes the same grid usable for pencils on paper and for a digital file at print resolution.
Pages can be saved, and saved pages roll up into an issue review. There you see the panel statistics for the whole issue together with a density chart, which shows how crowded or open your pages are across the run. It is a practical way to spot an issue that drifts towards sameness, a sequence of unusually dense pages, or a quiet stretch that could carry a larger panel. Planning at the level of the issue, not only the page, helps the pacing hold up from the first page to the last.
The tool is aimed at anyone who works to a printed format: comic artists, letterers, self publishing creators, students learning page construction, and studios preparing templates before the art begins. The app keeps the arithmetic of the grid out of your way, so the time goes into the panels themselves.
