QR Code Brand Guidelines

Best practices for designing, printing, and displaying QR codes. Follow these guidelines to ensure your QR codes are always scannable and look professional.

Minimum Size

The minimum recommended size depends on the scanning distance and print quality:

Use case Minimum size Recommended format
Business card 1,5 × 1,5 cm SVG or PDF at 300+ DPI
Flyer / brochure 2 × 2 cm SVG or PDF
Poster (A3/A2) 3 × 3 cm SVG
Billboard / banner Scale proportionally SVG
Screen / digital 200 × 200 px PNG

Rule of thumb: The scanning distance is roughly 10× the size of the QR code. A 3 cm code scans from ~30 cm away.Pravidlo palce: Vzdálenost skenování je přibližně 10× velikost QR kódu. Kód 3 cm se naskenuje ze ~30 cm.

Quiet Zone

The quiet zone is the blank margin around the QR code. It's critical for scanners to identify where the code starts and ends.

Color & Contrast

Color is the most common reason QR codes fail to scan. Follow these rules:

Safe Color Combinations

Modules Background Contrast ratio Result
Black (#000) White (#FFF) 21:1 Excellent
Dark blue (#1a365d) White (#FFF) 12.6:1 Excellent
Dark green (#166534) White (#FFF) 8.2:1 Good
Red (#dc2626) White (#FFF) 4.6:1 Minimum
Yellow (#eab308) White (#FFF) 1.9:1 Won't scan

Logo in QR Code

Adding a logo increases brand recognition but reduces the data area. Follow these rules:

Frame & Call to Action

A frame with text around the QR code significantly increases scan rates — by up to 80 % according to some studies.
