Calculate manga canvas pixels for B5, A5, and custom trim sizes. Include bleed and safe-area guidance for monochrome or color artwork.
Open Manga DPI Calculator Free browser toolManga Screentone Checker
Inspect a local manga tone raster at true 100% pixel scale, estimate its horizontal and vertical repeat periods, and compare it with a clearly labeled resize simulation.

Screentone Frequency Calculator FAQ
Production answers without the guesswork
What is LPI in manga screentones?+
LPI describes how many repeating tone cells fit in one inch. Higher LPI creates smaller, denser cells at the same document DPI.
Why can screentones create moiré?+
Resizing, overlapping patterns, display scaling, or insufficient pixels per cell can produce visible interference patterns.
Is one LPI safe for every manga workflow?+
No. The output target, document DPI, resizing, printer, and tone overlap all affect the result.
