Logo QR Code

A logo QR code is a design in which a company logo or icon is overlaid on the central part of a QR code. It makes use of the QR code's error correction function, and because the data in the part hidden by the logo can be restored from the remaining area, the code can be read correctly.

When adding a logo, it is common to set the error correction level to H (about 30% recoverable). If the area of the logo is too large, reading fails, so it is safe to keep it to about 20-25% of the whole QR code. It is effective for raising brand awareness and improving the design.

When creating a logo QR code, keeping the area of the logo within 20-25% of the whole QR code is a safe guideline. The roughly 30% that error correction level H can restore is a proportion of the data (codewords), not the upper limit of the area that may be covered. Select error correction level H (about 30% recovery) to compensate for the data loss corresponding to the area the logo occupies. After creating the code, be sure to test reading it with several smartphones.
