QR Code Size Guide — Minimum Sizes for Print & Digital
What size should your QR code be? Minimum 2cm × 2cm for business cards, 5-10cm for menus and table tents, 15cm+ for posters, and 30cm+ for billboards. Always download in SVG for print. Complete sizing guide with recommendations for every use case.
Minimum 2×2cm (0.8×0.8 in). QR codes on business cards are scanned at close range (10-20cm). Always use SVG format for sharp printing.
Table Tents & Menus: 5cm+
5-10cm (2-4 in) for restaurant tables, menus, and counter displays. Scanned from 30-50cm distance.
Flyers & Brochures: 3cm+
3-5cm (1.2-2 in) for printed flyers, brochures, and handouts. Ensure high contrast and avoid placing on busy backgrounds.
Posters & Signage: 15cm+
15-25cm (6-10 in) for posters and wall signage. Must be scannable from 1-2 meters away. The further the scan distance, the larger the code.
Billboards & Banners: 30cm+
30cm+ for large-format displays. Rule of thumb: the QR code should be 1/10th of the scanning distance (3m distance = 30cm code).
Digital Screens: 240px+
Minimum 240×240 pixels for websites and digital displays. For social media, 400×400px+ is recommended for clarity.
How it works
1. Determine Scan Distance
How far will the scanner be from the QR code? Business card = 15cm, table = 40cm, poster = 1.5m, billboard = 5m+.
2. Calculate Minimum Size
Rule: QR code size = scanning distance ÷ 10. A 1-meter scan distance requires a 10cm QR code.
3. Choose SVG Format
Always download in SVG for print. SVG is a vector format — it scales to any size without losing quality.
4. Test Before Printing
Print a test copy and scan it from the expected distance with different phones to verify reliability.
Frequently asked questions
The absolute minimum is about 1.5cm × 1.5cm, but 2cm × 2cm is recommended for reliable scanning. Smaller codes require perfect printing and close-range scanning.
