1The 10:1 Sizing Formula

For posters or flyers, measure expected viewing distance and divide by 10. A poster scanned from 5 feet requires a minimum 6-inch QR code.

2Protect the Quiet Zone

Never crop the white border surrounding the QR code. Cameras require a 2 to 4 module buffer to distinguish the code from background artwork.

3Use Vector SVG for Print

Send your print shop or signmaker our downloadable SVG file. Vectors stay razor-sharp at any physical dimension without pixel blur.
