Enter the final panel width in pixels and choose whether the page should be proofed mobile-first.
These are safe starting points, not font specifications. Typeface width, balloon shape, export scaling, and the reader’s device still need a final proof.
The safe area keeps dialogue away from trim, gutters, and mobile edges.

Frequently asked questions
Are the suggested font sizes exact?
No. They are starting estimates based on panel width. Typeface width, x-height, balloon shape, line breaks, export scaling, and device size all affect readability.
Why use the final panel width?
Lettering that looks large on an oversized working canvas can become unreadable after export. Use the expected final pixel width for more useful guidance.
Does right-to-left manga change the margins?
The side-margin calculation is symmetrical. Reading direction changes balloon placement and flow, which you can check separately with the Comic Reading Order Checker.
How is this different from Comic Lettering Checker?
This helper recommends page geometry and type-size starting points. Comic Lettering Checker estimates whether specific dialogue lines fit within a bubble capacity.
