Using DMRE (Data Matrix Rectangular Extension)

DMRE adds more rectangular sizes to Data Matrix, giving you more ways to fit a code on a long, narrow label. It is a separate extension, not a square code stretched sideways. Use it when your label system and scanner support DMRE.

Download PNG for documents or SVG for a sharp, resizable print layout. Generation takes place in your browser, without an account.

Questions about DMRE (Data Matrix Rectangular Extension)

Can every Data Matrix scanner read DMRE?
Do not assume so. Check for DMRE support and test the final printed label on your actual reader. If it is unsupported, use ordinary rectangular or square Data Matrix. Capacity depends on the characters; enlarging the image does not make more data fit.
How do I check the code before printing?
Leave the white margins intact, keep the image in proportion and scan a sample at its final printed size with the device you intend to use.
