Grid Matrix — Barcode Format Guide & Generator
Grid Matrix is a one-dimensional linear symbology in the Matrix family. Chequerboard matrix code with GB 2312 support. Beyond consumer QR codes, matrix symbols mark surgical instruments, electronics PCBs, automotive parts, payment slips and postal items.

Data format
Enter the payload as plain text. The encoder enforces each symbology’s character set and length rules, and rejects out-of-spec input with a clear message instead of silently producing a bad symbol.
Strengths and limitations
Strengths
- Stores far more data than a 1D barcode — URLs, IDs or full text payloads.
- Built-in error correction keeps a partially damaged or obscured symbol readable.
Limitations
- Needs a camera-based reader (imager or phone); red-laser-only checkouts cannot read it.
- Print quality and contrast matter more — poor prints fail more often than large 1D bars.
Generate one in QrDeco
- Open QrDeco and choose Grid Matrix from the format list.
- Type or paste your data — for example 网格码示例 Grid Matrix.
- Adjust size, colours, quiet zone or human-readable text in the style panel if you need them.
- Export an SVG or PDF for print, or a PNG for screens — generated locally in your browser, nothing is uploaded.
Options
- Error correction: ~10% · ~20% · ~30% · ~40% · ~50%
- Symbol size (1-13): from 1 to 13 — set it to 0 to let the encoder choose automatically.
Scanning and printing tips
- Leave the quiet zones clear — blank space on both sides of the bars is part of the symbol.
- Print dark bars on a light background; red-only bars can vanish under red laser light.
- Keep the bars vertical to the scan direction and print at the symbol’s standard magnification.
- Verify one printed sample with a real scanner before committing to a full run.
