Guides to QR Codes That Actually Work
The details that decide whether a QR code does its job are the ones nobody writes down: what it can hold, how big it has to be for the distance it's read from, and where a different symbol would serve you better. These guides answer one of those questions each.
Questions? Answered
No. The generator's defaults produce a code that scans, and most people never need to change them. These guides are for the cases where the defaults aren't enough - a logo in the middle, a billboard, or a code that won't read.
Whichever names the decision in front of you - each guide takes one and answers it end to end, so there's no order to work through. If you're choosing between symbol types at all, start with QR code vs barcode, since that decision sits above the rest.
No. Error correction levels, quiet zones, and module sizes are part of the QR standard, so everything here holds for a code made with any generator. Where a setting is named, KoloQR exposes it in the generator on the homepage.
When something changes that would change the advice. Each guide shows the date it was published, and a revised guide shows when it was last updated, so you can see how current what you're reading is.
