How we test our paper
TrueGrid verifies PDF dimensions and vector geometry by script; physical printing and device imports are not yet tested, and errors can be emailed.
Scope
TrueGrid provides printable paper templates. The PDFs (clean grid, small source line in the margin) are free for personal and classroom use.
1 · File geometry
A build script reopens every generated PDF with an independent parser and verifies page dimensions, selected vector geometry and file-size budgets.
2 · Physical prints and devices
Physical printing and device imports have not yet been tested. The status table keeps those checks separate from verified file geometry.
Report an error
Email hello@graphpaperprintable.org with the page URL, file name and measured result. Include print or device details when they are relevant.
