Ruler Printer Test Page – Free Printable Ruler to Verify Print Scaling & Accuracy
Verify your printer's scaling, alignment, and dimensional accuracy.
What Is the Ruler Printer Test Page?
The Ruler Printer Test Page is a printable ruler and shapes test page designed to verify your printer's scaling, alignment, and measurement accuracy. This diagnostic tool features precise centimeter and inch rulers, geometric shapes with known dimensions, and alignment guides to ensure your printer produces accurate measurements for technical drawings, crafts, and precision work.
Perfect for quickly spotting distortions or resolution issues, this test page helps ensure dependable results for any project where print size precision is critical, including engineering documents, CAD prints, and craft templates.
How to Use the Ruler Printer Test Page
Print at 100% scale (no fit-to-page)
Click print and ensure scaling is set to "100%" or "Actual Size". Do not use "Fit to Page" or any scaling options.
Compare printed ruler with a real ruler
Use a physical ruler to measure the printed millimeter and inch rulers. They should match their labels exactly.
Verify circles, squares, and alignment
Measure the 100mm square and 50mm circle. Shapes should be perfectly proportioned without distortion.
Confirm both inches and centimeters accuracy
Use the crosshair guides to check for print offset and verify both metric and imperial measurements are accurate.
