Stretching the matrix
Non-uniform scaling turns square modules into rectangles and can harm decoding.
Lock aspect ratio and resize by whole modules where raster output is required.
Data Matrix generator
Generate a compact Data Matrix ECC 200 symbol
Data Matrix stores data in a two-dimensional grid with error correction and a distinctive solid/alternating finder pattern. The generator selects an ECC 200 size for the payload, shows the exact text being encoded and avoids decorative edits that would damage modules.

A practical workflow
How to use it
- 01
Enter the exact payload
Check encoding and delimiters against the consuming system before generation.
- 02
Let capacity determine the matrix
Use the selected ECC 200 symbol size rather than forcing data into too few modules.
- 03
Export with square modules
Keep equal horizontal and vertical scaling, a clear quiet zone and a testable final module size.
Avoid rework
Common errors and precise fixes
Assuming all Data Matrix data is GS1
A general ECC 200 payload does not gain GS1 semantics without the appropriate FNC1 and element-string rules.
Use an explicitly supported GS1 DataMatrix workflow when standards-based data is required.
Know the limits
The general generator does not claim support for every GS1 or regulated Data Matrix profile.
Payload capacity, module size, printer resolution and reader optics must be assessed together.
Questions, answered
Before you continue
What does ECC 200 mean?
It identifies the modern Data Matrix error-correction scheme used to recover data from a limited amount of symbol damage. It does not guarantee reading through arbitrary distortion.
Can I place a logo in the middle?
BatchLabel does not recommend or automate logo overlays. Error correction is not permission to obscure modules or finder patterns; preserve the generated symbol intact.
