QR Code Size Guide for Print: Business Cards, Posters, Packaging

Rule of thumb

Start with a minimum size of 2 x 2 cm (0.8 x 0.8 in) for close-range scanning, then scale up based on distance.

Recommended sizes by format

• Business cards: 2 to 2.5 cm
• Flyers / brochures: 2.5 to 3 cm
• Product packaging: 2.5 to 4 cm
• Posters / window signage: 4 to 6 cm
• Large outdoor signage: test from real scan distance; usually 8 cm+

Do not ignore quiet space

Leave clean white margin around the QR code. Without this, even a large code can fail to scan.

Contrast matters

Dark code on a light background is safest. Decorative gradients and low-contrast colors reduce readability.

Before you print at scale

Test a sample in real lighting and real placement conditions. If it takes more than 2 seconds to scan, improve size or contrast.
