QR code print size guide

How large should a printed QR code be? Practical sizing tips plus how QR Promise handles preview and downloads (7-day card-required trial, then $3/mo).

Our Promise

Static codes on QR Promise are generated in your browser, contain your data directly, and never route through us — so they can never be deactivated.

Rule of thumb

About 1 inch (2.5 cm) square minimum for hand-held scanning. Go larger for wall posters or longer distance.

Quiet zone

Leave a blank margin around the code. Crowding the edge makes cameras fail.

Contrast

Dark modules on a light background. Avoid busy photos under the code.

Files

SVG scales cleanly for print vendors. Preview free on QR Promise; downloading starts the 7-day card-required trial.
