How Small Can a QR Code Be?
QR codes can technically be incredibly small, in fact, as tiny as 1 cm x 1 cm (0.4 x 0.4 inches). But that is way too small to make sure the type of QR code you create to market your business and products.
For the vast majority of us relying on smartphone cameras, the minimum size for a QR code is considerably larger for reliable scanning.
- For general applications, a widely accepted practical minimum is 2 cm x 2 cm (0.8 x 0.8 inches).
- If you're printing on business cards or other small marketing materials where precision is paramount, aiming for 2.5 cm x 2.5 cm (1 x 1 inch) offers a much better chance of a successful scan.
Pushing these size limits too far, whether they are too small or too big, will almost always result in a poor user experience.
Factors That Decide the Ideal QR Code Size
There’s no magic code size that works for every situation. The ideal size really depends on several key factors, such as the ones below:
-
Scanning distance
The 10:1 Rule The further away a QR code will be scanned, the bigger it needs to be. For example, a 2 cm code is best scanned from about 20 cm away.
-
Data complexity and capacity
More information, like a long URL, usually means you need a physically larger code for it to be easily readable.
-
Error Correction Level (ECL)
This feature allows codes to be scanned even if damaged. Higher error correction levels make the code more resilient but also larger.
-
Printing quality and resolution
Aim for at least 300 DPI to avoid poor quality when you print out the code.
-
Amount of customization
Make sure there’s a strong contrast between the code and its background without an excessively large logo.
