Source: 2D Codes, Basic Specifications for QR Code (JIS X 0510)
Maximum Data Capacity
Even with the same 2D code, the maximum quantity of information that can be stored depends on
the symbol size of the code. In other words, the symbol size must be increased to increase the data
capacity. The data capacity also depends on the type of characters used for the information con-
tained in the code. The QR Code and DataMatrix code, the maximum number of characters for the
same symbol size will be greatest with numbers only and then with alphanumerics, and will be the
least with 2-byte characters. The data capacity also depends on the order and combination of char-
acters used.
