Dan Korn Posted April 12 Posted April 12 Yes, of course, there's a limit to everything. The nominal limit is 7,089 characters, though it depends on the encoding mode, symbol size, and error correction level. The spec is here: https://www.qrcode.com/en/about/version.html Also, there are practical limitations on how much data various scanners and applications can scan. If you actually make a QR barcode with 7000 characters, it's going to either be huge, or have pixels so small that any phone will have trouble reading them. So my advice is: keep the QR codes small. If you have to encode a large amount of data, consider encoding a URL to a webpage or a PDF with the information instead. Quote
