Scanning Distance

How far will people be when they scan?

Error Correction Level Higher = more damage resistant but larger QR code needed

Recommended QR Code Size

1.2"

minimum size

Minimum: 1.2 inches (3 cm)

Recommended: 1.5 inches (3.8 cm)

Comfortable scanning at 12 inches

Table Tent / Menu	18 inches	1.8" (4.5 cm)	2" (5 cm)
Poster (small)	3 feet	3.6" (9 cm)	4" (10 cm)
Banner / Sign	6 feet	7.2" (18 cm)	8" (20 cm)
Trade Show Display	10 feet	12" (30 cm)	14" (35 cm)
Billboard	30+ feet	36" (90 cm)	48" (120 cm)

The industry standard for QR code sizing is the 10:1 ratio: divide the scanning distance by 10 to get the minimum QR code size.

QR Size = Scanning Distance ÷ 10

Example: 3 feet away → QR code should be at least 3.6 inches

This formula assumes:

Pro tip: When in doubt, go 20-25% larger than the minimum. It costs nothing extra to print bigger, but a QR code that won't scan is worthless.

Dark code on light background works best. Avoid low-contrast color combinations.

Leave white space around the QR code equal to 4x the size of one module (small square).

Always scan your QR code with multiple phones before sending to print.

Light QR codes on dark backgrounds can cause scanning issues on older phones.

Logos in the center are fine with high error correction, but don't cover more than 30%.

QR codes must be perfectly square. Stretching or skewing breaks them.
