PrintableRuler.online6 Inch Ruler — PDF Download
A 6 inch ruler with 1/16in tick detail, built at exact physical scale in the PDF itself — no browser or screen calibration needed. Prints on a single US Letter page.
Paper: US Letter · 1 sheet · 1/16in tick detail
Before printing: open the PDF's print dialog and set Scale to 100% / "Actual size" — never "Fit to page" — or the ruler will print undersized.
Why a PDF instead of the on-screen builder?
PDF page geometry is defined in physical units (points), so a PDF viewer's print pipeline reproduces it at true scale automatically — there's no screen-DPI guesswork involved, unlike measuring directly against a laptop or phone display.
