QR-Code size - what must be considered?

QRCodes (Quick Response Codes) are small, black and white squares that can be filled with a variety of information. For example, they can be URLs, contact information, or even text messages. You can scan them with a smartphone camera to quickly and easily retrieve the information they contain. Due to their popularity in today’s digital world, it’s important to know what size a QR-Code should be. Otherwise, the scannability could be compromised….

In general, a QR-Code should be large enough to be captured and read by a standard smartphone camera. A QR code should be at least 1 inch (2.54 cm) on each side. This ensures that it can be successfully read by the many devices. However, a larger QR-Code increases the likelihood that it will be successfully scanned. Especially if it is placed on a poorly lit, uneven surface or the camera used is of low quality.

However, there are also situations where you might need a smaller QR-Code. For example, you may want to include a smaller QR-Code on a printed product such as a business card or poster without it taking up too much space. In this case, however, the QR-Code should still be as large as possible without compromising the readability or design of the printed piece.

There are also special QR-Code creation tools that allow you to resize QR-Code. This way you can customize it to fit your needs. QR-Codes with lower density can also be displayed larger, which also increases the chance that it will be read successfully. It is also important that you make sure that the QR-Code is not distorted or twisted. Otherwise, this can significantly affect the readability.


In practice, the size of a QR-Code varies depending on the use case and the environment in which it is placed. In any case, however, it is important that your QR-Code is large enough to be successfully read by a standard smartphone camera. Also, don’t distort or twist it. A good basic rule is to make the QR-Code as large as possible without compromising the readability or design of the printed product. In situations where space is limited, make sure the QR-Code is displayed as large as possible within the space…. It is best to perform a test print before large-scale production and playout, this way the functionality of the QR-Code can be checked and the size or placement can still be adjusted if necessary. By following these recommendations and using special QR-Code creation tools, you can ensure that the QR-Code can be read successfully.
