One of the most common QR mistakes is making the code too small for the environment. The right QR code size depends on viewing distance, lighting, print quality, and how fast you expect people to scan.
Practical QR size rules
- Business cards: about 0.8 to 1 inch
- Menus and table tents: about 1.2 to 1.6 inches
- Flyers and handouts: about 1.4 to 2 inches
- Indoor posters: about 2 to 3 inches
- Outdoor posters: about 3 to 4 inches or more
Why larger is usually safer
Larger QR codes are easier to scan in dim light, on older phones, through glare, and at off angles. If there is any doubt, size up and test.
Best export format for larger codes
For printed material, SVG is the best export because it stays sharp at any size. PNG can work well too, but only when exported at high enough resolution.
