QR Code Printing Size Guide for Cards, Posters and Packaging

There is no single perfect QR code size for every print job. The right size depends on scanning distance, encoded data, print quality, surface and lighting. A code on a business card can be smaller than one displayed on a wall, but both need enough detail and empty space.

A practical starting point

For close-range items such as business cards, labels and table cards, approximately 2 × 2 cm is a sensible minimum starting point for a simple QR code. Use a larger size when possible, especially for a long URL, dense data, textured material or lower-quality print. A minimum is not a guarantee, so test the finished product.

Estimate from scanning distance

A common planning guideline is to make the code width roughly one-tenth of the expected scanning distance. A code scanned from 1 metre may need to be around 10 cm wide. Camera quality, lighting, content density and placement can require a larger code.

Keep the quiet zone

Do not crop the blank margin or place text, borders and graphics too close to the pattern. Maintain at least the quiet zone produced by the generator on every side.

Resolution and file format

Use SVG for professional layouts and large-format printing because it scales cleanly. A high-resolution PNG works for small and medium print, but enlarging a small PNG creates blurred edges. Do not use a compressed screenshot as the print master.

Print test

Print one sample at actual size. Scan it with different phones, angles and lighting, then verify the exact destination or encoded information. Avoid glossy reflections, folds, seams and strongly curved surfaces.
