The symbol
The matrix is selected based on indicative capacity. The exact content and encoding may result in a different matrix.
NWS LASER TOOL · DATAMATRIX
Pre-size the code,
prepare the test.
Estimate a square matrix and the area to reserve based on your data, available area and target module size. The result helps prepare the study; it does not replace qualification on the part.

BEFORE THE TEST
Put the parameters
in the right order.
The final size of a DataMatrix depends on the exact content, the selected matrix, module size, quiet zone and intended reading method. This tool makes these assumptions visible to help prepare a more useful technical inquiry.
YOUR ASSUMPTIONS
Pre-size
the code area.
The capacities used are reference values for square Data Matrix ECC 200 symbols. The exact size depends on the actual encoding; for GS1, do not count the parentheses around application identifiers, and account for FNC1 and any separators.
RESULT
Enter your parameters,
then estimate the area.
The result will show the smallest indicative square symbol, the symbol dimensions excluding the quiet zone, and the total area to reserve.
HOW TO READ THE RESULT
An estimate
to be checked against the actual part.
The calculation shows the relationship between the data, modules and physical area. It does not, on its own, predict contrast, speed or a reading grade.
The area to reserve
The code area combines the symbol with a clear surrounding margin. It is compared with the declared width and height.
Reliable reading
Module size, material, lighting, geometry and reader must be considered together in a representative test.

What the tool
estimates—and does not estimate.
- Does the DataMatrix pre-sizer validate a DataMatrix?
- No. It provides an estimate of the size and area to reserve based on the entered assumptions. The exact data, material, process, reader and production conditions must be qualified on the part.
- Why is the quiet zone included in the calculation?
- The quiet zone is the clear space around the symbol. The GS1 DataMatrix guide specifies a width of at least one module on all four sides.
- Why doesn’t the number of characters give an exact size?
- The final size depends on the exact content and encoding method. GS1 data and some control characters use additional capacity. The result is therefore indicative.
