How Big Should a QR Code Be for Print?

How big should a QR code be for print?

As a rule of thumb, make a QR code at least one tenth of the distance it will be scanned from, and never smaller than about 0.8 inches (2 cm). A code read from 10 inches away should be at least an inch; a poster read from 10 feet should be at least 12 inches. When in doubt, print it bigger. A code that is too large never causes a problem, but one that is too small quietly fails.

The 10 to 1 distance-to-size rule

The simplest guide is a ratio: a QR code should be about one tenth as wide as the distance it is read from. Divide the scan distance by ten and that is your minimum code size.

• Read from 12 inches (a menu in hand): at least ~1.2 inches.
• Read from 5 feet (a store window): at least ~6 inches.
• Read from 20 feet (a poster across a room): at least ~2 feet.

It is a floor, not a target. Going bigger only makes scanning easier and faster.

Print size reference

Where it lives	Typical scan distance	Minimum code size
Business card, table tent	about 10 in	0.8 to 1 in (2 to 2.5 cm)
Flyer, menu, packaging	1 to 2 ft	1.2 to 1.5 in
Store window, easel sign	3 to 6 ft	4 to 8 in
Yard sign, poster	5 to 10 ft	6 to 12 in
Banner, building, stage	20 ft and up	2 ft and up

These are practical minimums. Bump them up for busy environments, low light, or older cameras.

Create your code and download a print file at any size.

Size is not the only thing that decides if it scans

Three more factors matter as much as raw size:

• Quiet zone. Leave a clear margin of empty space around the code, about four squares wide. A code crammed to the edge of a card or crowded by text gets harder to find.
• Data density. More data means more squares, which means a denser code that has to be printed larger to stay readable. Keeping the destination short keeps the code simpler.
• Square, not stretched. Never squeeze a code out of its square shape to fit a layout. Scale it evenly.

This is also a quiet advantage of dynamic codes: they encode a short redirect rather than a long URL, so the pattern is less dense and holds up better at small print sizes. More on the two types here: static vs dynamic QR codes.

Printable size checklist

• At least 0.8 inch (2 cm), and bigger for anything read from a distance.
• Apply the 10 to 1 rule for the real scan distance.
• Leave a clear quiet zone on all four sides.
• Keep strong contrast, dark code on a light background.
• Keep it square, never stretched.
• Print a proof at the final size and scan it on more than one phone before the full run.
