Help / Printing / Minimum size
How small can I print a QR code?
Count your data first
Module count grows with the amount of data encoded. A short link needs far fewer modules than a full vCard or a long URL with tracking parameters — shorten the destination before you shrink the code.
Read the minimum size in the editor
The editor's live readout shows the module count and the minimum print size for exactly what you typed, recalculated as you edit. These are the numbers for a typical dynamic code (a short link).
Add the quiet zone, not just the code
Scanners use the empty margin around the modules to find the code's edges. Nothing — a border, a logo, body text — should sit inside it, or a scan that should work won't.
Scan the physical proof
Print one sheet at final size on the final material, and scan it from where a customer will actually stand. A code that works on screen or on plain paper can fail once it's gloss vinyl in direct sun.
