Testing a QR code properly before printing or publishing it can save time, money and embarrassment. Follow this guide to ensure your codes scan reliably.

Multi-Device Testing

Test your QR code on at least 3 different devices: an iPhone, an Android phone and, if possible, an older model. Different camera apps and QR scanning capabilities vary between devices.

Distance Testing

Scan from the actual distance users will use. A code on a billboard needs to work from metres away; a code on a business card needs to work from a few centimetres. Adjust size accordingly.

Lighting Conditions

Test in bright sunlight, dim indoor lighting and under artificial light. Glare on glossy surfaces can prevent scanning. Matte finishes are more reliable.

Print a Sample First

Before ordering 500 flyers or printing a large banner, print one sample at the intended size and material. Test it thoroughly before committing to the full run.

Check the Destination

Scan the code and verify it goes to the correct URL, shows the right message or opens the expected app. Double-check the destination before publishing.

Common Problems

Code too small: Increase the size or reduce the amount of encoded data.
Poor contrast: Use dark code on light background.
No quiet zone: Ensure white space around the code.
Reflections: Use matte rather than glossy finishes.
Distortion: Avoid stretching or skewing the QR code image.
