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

## 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.
