How this works

Why a printed piece needs bleed at all

A press prints on a full sheet, and the finished piece is cut out of it afterward on a guillotine cutter. Cutting a stack of paper is never perfect to the thousandth of an inch, so if your background color or photo stops exactly at the trim line, a hair of drift in either direction leaves a thin white sliver of unprinted paper along that edge. Bleed is the fix: you extend the artwork past the trim line by a fixed amount, so the cutter always slices through printed area no matter which way it drifts.

The safe zone is the opposite margin

Anything that has to stay fully readable — body text, a logo, a phone number — needs the reverse protection: kept back from the trim line by a margin of its own, so the same cutting tolerance can never clip a letter or crowd a logo against the edge. That is the safe zone this calculator recommends, measured inward from the trim line rather than outward from it.

Both numbers are conventions, not laws of physics, and a job with unusual finishing — a die cut, a fold close to an edge, an oversized sheet — can call for more of either. When in doubt, ask before you export the file.
