## What is the minimum matrix size for a square 2D Data Matrix barcode?

Data Matrix Size Considerations X-dimensions are commonly displayed in “mils” (thousandths of an inch), inches, or millimeters. The minimum acceptable X-dimension for Data Matrix symbol is 19.5 mils, or 0.0195” (0.494 mm).

## How small can a Data Matrix barcode be?

The most popular application for Data Matrix is marking small items, due to the code’s ability to encode fifty characters in a symbol that is readable at 2 or 3 mm2 (0.003 or 0.005 sq in) and the fact that the code can be read with only a 20% contrast ratio.

**How small can a 2D barcode be?**

2D codes can be as small as 1/30th the size of a typical barcode containing the same data. As a result, 2D codes can be printed on electronics and other small parts where space is limited.

**How many characters are in a data matrix code?**

A data matrix code is a 2D code that is made of black and white cells that are typically arranged in a square pattern (although rectangular patterns also exist). The number of rows and columns increases with the amount of information stored in the code, which is limited to 2,335 alphanumeric characters.

### What ECC 200?

ECC200 has upgraded error correction capacity to eliminate distortion problems. It uses Reed-Solomon for error correction that restores data when a part of a code is damaged. ECC200 is internationally standardized. Generally ECC200 version is used when DataMatrix code is required.

### What is a 2D data matrix barcode?

Data Matrix is a 2D barcode symbology with very high data density. Data Matrix symbols are printed in square or sometimes a rectangular pattern. Each dot of a Data Matrix symbol represents a bit. This is in contrast to linear bar-codes, where the information is encoded in the ratio of the bars or spaces to each other.

**How much data is a Data Matrix?**

The maximum capacity for Data Matrix codes is up to 3116 numeric characters or up to 2335 alphanumeric characters or up to 1555 bytes of binary information.

**What is 2D Data Matrix barcode?**

## What is 2D in pharma?

2D-Pharmacode is a variant of the Data Matrix symbology that is designed for use in pharmaceutical packaging. It combines a Data Matrix symbol with two optional supplemental modules: color fields and a trigger mark.

## Which is an example of a Data Matrix?

A data matrix is a matrix which stores data. For example, if we were collecting data on students in the class, the observations would be each individual student in the class.
