The best resolution for a digital QR code is 240 x 240 pixels. The minimum recommended resolution for QR codes on print materials is approximately 38 x 38 pixels. Following these guidelines will ensure your code is readable; however, you must always adjust the resolution based on the use case.

The resolution of your QR code will also depend on its size. For example, if you plan to apply your QR code on a billboard, both the size and resolution need to be increased to ensure proper scanning. However, a standard resolution and size are sufficient if the marketing material is small, like a brochure or flyer.
