QR Code Size for Flyers, Brochures & Direct Mail

Flyers and folded brochures (A4, A5, DL formats) are typically scanned while being held in one hand or resting on an office desk, placing the camera at an expected scanning distance of 30 cm to 40 cm. Following the 10:1 viewing distance rule, the QR code on a marketing flyer should measure between 25 mm and 35 mm (1.0 to 1.4 inches). When designing high-volume print runs, factoring in paper stock absorption, dot gain, and quiet zone margins ensures your direct mail and promotional handouts convert recipients smoothly into website visitors. Printing smaller than 25 mm risks camera focus failures on uncoated stock where ink bleed can soften module boundaries.
