Datamatrix is a matrix (2D or two-dimensional) barcode which may be printed as a square or rectangular symbol made up of individual dots or squares. This representation is an ordered grid of dark and light dots bordered by a finder pattern. The finder pattern is partly used to specify the orientation and structure of the symbol. The data is encoded using a series of dark or light dots based upon a pre-determined size. The size of these dots is known as the X-dimension.

Datamatrix is capable of encoding variable length data. Therefore, the size of the resulting symbol varies according to the amount of data encoded. Accordingly, this section can approximate the size of a given datamatrix barcode based on this parameter.

The size of a Datamatrix is dependent upon the amount and format (numeric or alphanumeric) of the encoded information: numbers and characters are encoded in terms of bits, represented by dark or light “dots” or “modules” of an identical size. The larger the number of bits required, the larger the symbol will be.

The maximum amount of data that can be encoded in the square form of datamatrix. Data Matrix can encode up to: 2,335 alphanumeric characters, or 3,116 numbers.

The Datamatrix supports various encoding structures which can be used in the same symbol simultaneously: ASCII, ISO/IEC 646, C40, Text, X12, EDIFACT and Base 256. These structures provide an opportunity to maximise the efficiency of encoding the required data in a Data Matrix symbol.
The simplest solution is to encode data using the subset of ISO/IEC 646 (equivalent to ASCII table 256) for all the information. This limited character set is supported by almost all computer systems available around the world today. It is strongly recommended to make ISO/IEC 646 (or the equivalent ASCII 256) the default option.
