Printing QR Codes: Size, Paper and Settings
By Qrenzo · 6 min read ·
Printing a QR code is easy, but small mistakes make it hard to scan. Follow these basics and your printed codes will work on the first try.
Pick the right file format
- PDF is best for printing. It is vector, so the code stays perfectly sharp at any size.
- PNG is a sharp image at 300 DPI, ideal for sending to a print shop or placing in a document.
- JPG is a smaller file that is fine for sharing or printing at normal sizes.
Qrenzo lets you download your flyer in all three formats. Choose PDF when you can.
Print big enough
A common minimum is about 2 cm (0.8 in) for scanning at arm’s length. For signs viewed from further away, make it larger. Our guide on what size a QR code should be has a simple distance rule.
Use the right paper and ink
- Matte white paper works best. Glossy paper reflects light and can stop a scan.
- Print in black or very dark color on a light background.
- Turn off ink-saver or draft mode, which makes the dots faint.
Set the printer to 100%
In the print dialog choose Actual size or 100%, not Fit to page. Shrinking the page shrinks the code and can make it too small to scan.
Printing at home or at a print shop
A normal home printer is fine for flyers. For larger runs, stickers or signs, send your PDF to a print shop and ask for a single proof first. See how to print a QR code flyer at home or in a shop.
Test before you print many
Scan one printed copy with two phones, at the real distance and in the real lighting. Use our test checklist before you approve a big print run.
