Therefore, it’s crucial to have some white space around the QR code. If it’s crowded and surrounded by other elements, a QR code scanner device may struggle to detect and scan the QR code. Where and how you place a QR code is essential for higher scans. If the foreground color is pink, red, purple, or green, keep the background color white or closer to white. Technology has advanced, and aesthetics are equally important, but it is possible to play around with just one color instead of both. There is a reason the initial QR codes were only black and white. The contrast between the background and foreground color must always be high. This way, you can seamlessly find the right logo size without facing scannability issues Low color contrast Or better, QRCodeChimp has a built-in indicator that gives you an error when the logo size is too big. You’ll need to experiment with different sizes to ensure you don’t compromise on scannability. Now, finding how large the logo can be is a matter of hit and trial. However, scanning issues may arise if the logo is too large. Large Logo sizeĪdding a logo to your QR code is crucial for branding. The logo size placed on a QR Code must be 21*21 – 177*177 modules (grows by four modules/side), and the attached structure must be a maximum of 16 symbols. Tiny QR codes are unlikely to attract attention. Apart from scannability, size also affects visibility. This means your QR code’s size should be 1/10th of the estimated distance between the code and the scanning device. Ideally, a QR code should have a size-to-scan ratio of 1/10. The size-to-scan ratio is an effective way to determine the right size for your QR code. T he minimum size should be 2×2 cm (0.8×0.8 in). If your QR code is too small, it may not scan properly.
