ZPL Coordinate Ruler
Overlay a coordinate ruler on ZPL-style label dimensions to check field placement, edges, margins, and DPI assumptions before printing.

Density changes rendering, not ZPL coordinates. Use DPI Converter to scale code.

Rendering sends ZPL to Labelary. Share links contain your label: use sample or masked data.
How to use it
Paste the script
Use real content from ERP, WMS, POS, or printer templates.
Review preview and fields
Check text, barcodes, coordinates, size, and obvious risks.
Confirm before real printing
Preview reduces test prints, but final validation still belongs on real hardware.
ZPL Coordinate Ruler FAQ
No. It highlights coordinate and edge risks, but real media calibration, ^PW, ^LL, and printer DPI still need a physical check.
The ruler is a browser-side planning aid for coordinates, dimensions, and placement notes while you prepare or review ZPL.
Label home, calibration, media gap, DPI, and command choices such as ^FO versus ^FT can move fields compared with a simple browser ruler.
