QR codes are more and more popular for obvious reasons. They represent a quick way to promote something. It is all about versatility and convenience. Whether it is your business address, a link to your official website or a vCard to end up in a user’s address book, QR codes are a good opportunity in marketing.
Creating your own QR code is fairly simple – there are plenty of websites allowing you to create your own. The whole procedure takes seconds only, as the code is instantly created based on the information you provide.
But how small can you make a QR code so they still scan?
What Affects the QR Code Size
QR code size depends a lot on where you use this QR code. Are you going to put it on a big billboard in the city center? Obviously, it should be much bigger there than if you were to put it on a small product package. The general idea is fairly simple – the distance between the code and the scanning smartphone is one of the most important factors in deciding on the size.
Size & Style
Another consideration is the size of the dots used to create the code. The dots become smaller as you add more data. Add a basic website and your QR code will be quite clean – easy to resize according to your needs. Add plenty of data and you will have a lot of small dots. At this point, if you make the QR code too small, some of the dots may stick to each other, while others will simply disappear.
Keep your QR Codes Short
To keep your QR codes as readable and clean as possible, we recommend to try our free QR Dynamic Links. This helps keep the contents small by using shortlinks. You also have the benefit of tracking your visitors and changing the content later, even after you have already printed your QR codes.
QR Code Sizing Formula
Most smartphones come with a simple formula for QR code scanning. The ratio is about 10:1. Think about the scanning distance and divide it by 10. If you plan to add a QR code in a magazine or a flyer, it will most likely be scanned from a close distance, such as 5 inches. In this case, the code can be 0.5×0.5 inches and still scan properly.
Maximum QR Code Size
If you want to place your QR code on a building or any other large format media, it will usually be scanned from a long distance. Use the same formula to determine the minimum QR code size.
There is no limit for maximum sizes, a QR code can be as big as you like. Just make sure that it fits into the smartphone camera from a normal scanning distance. When printing larger QR codes, make sure you are using vector formats, like .PDF, .EPS or .SVG. All these formats are available for free with the Pageloot QR Code Generator tool.
Minimum QR Code Size
Most specialists agree that 0.4×0.4 inches (1×1 centimeters) is the smallest readable size for most smartphones. We would recommend to at least double those dimensions – 0.8×0.8 inches or 2×2 centimeters. In other words, ideally you want to be above this size for magazines, business cards, flyers and so on.
Remember the distance formula, as well as the minimum size requirements. Keep in mind that bigger is usually better, especially as there might be other factors to affect the size, such as the QR code color. Make sure that the QR code and background are not similar in color and are clearly separable.
How small or big can you make a QR code for printing? When in doubt, always test!
