QR Print Area Calculator

Enter stock size, margins, and bleed to get the usable print area that a QR code and its quiet zone must fit inside. All values use the same unit you enter.

1. Enter stock and margins

Formulas: usable width = stock width − left margin − right margin − 2 × bleed. Usable height = stock height − top margin − bottom margin − 2 × bleed. Usable area = usable width × usable height.

The QR code plus its quiet zone must fit inside the usable width and height. If it does not, enlarge the stock or shrink the margins — never shrink the quiet zone.

Design Inside the Usable Area

A layout that fits the stock size on screen can still fail on press if margins and bleed were never subtracted. The usable area is the only space that is guaranteed to survive trimming and stay clear of the edge. Sizing the QR code against that rectangle — not the full stock — is what keeps the code and its quiet zone intact on the finished piece.

A quick check

Compare the usable width and height with the code size your viewing distance requires. If the code does not fit, change the layout or the stock size; squeezing the code or its quiet zone trades away scans.

Frequently Asked Questions

What is the difference between margin and bleed?

Margin is the blank space inside the finished piece that content must stay out of. Bleed is extra artwork extending past the trim edge so the cut does not leave a white sliver. Both shrink the usable area, but for different reasons — margin protects content, bleed protects the edge.

Why subtract bleed twice?

Bleed applies on both sides of each dimension: left and right for width, top and bottom for height. A 3 mm bleed removes 6 mm from the usable width and 6 mm from the usable height.

Can the QR code sit in the bleed area?

No. The code must sit fully inside the usable area, with its quiet zone clear of the margin. Anything in the bleed or margin risks being trimmed off or crowded by the edge.

What units does this use?

Any consistent unit — millimetres, centimetres, or inches — as long as every field uses the same one. The areas come out in that unit squared.
