Ruler & Dimension Printer Test Page
Verify your printer’s dimensional accuracy with printed rulers in centimeters and inches, a measurement grid, and a reference line. Use a physical ruler to check that printed measurements are exact.
Ruler & Dimension Printer Test Page
IMPORTANT: Print at 100% scale (no "Fit to Page") for accurate measurements.
Horizontal Ruler — Centimeters (0–18 cm)
Horizontal Ruler — Inches (0–7 in)
Vertical Ruler — Centimeters (0–12 cm)
Measurement Grid (1 cm squares)
Grid is 10 cm wide by 6 cm tall. Each square should measure exactly 1 cm x 1 cm.
Reference Line: Should Be Exactly 10 cm
Measure this line with a physical ruler. It should be exactly 10 cm (100 mm / 3.937 inches).
Reference Line: Should Be Exactly 1 Inch
Measure this line with a physical ruler. It should be exactly 1 inch (25.4 mm).
How to Use This Test Page
- Load plain white Letter or A4 paper into your printer.
- Click the “Print This Page” button above.
- IMPORTANT: In the print dialog, ensure scaling is set to “100%” or “Actual Size” — do not use “Fit to Page.”
- Print the page and place it on a flat surface.
- Use a physical ruler or measuring tape to verify the printed rulers and reference line against the assessment guide.
What to Look For
- Centimeter and inch rulers should measure correctly when compared against a physical ruler.
- There should be no stretching or compression in either horizontal or vertical directions.
- Measurements should be consistent across the entire page — not just accurate in one area.
- The “measure this” reference line should be exactly 10 cm when checked with a real ruler.
- Grid squares should be perfectly square with equal horizontal and vertical dimensions.
Troubleshooting Tips
- Measurements are slightly too large or too small
- Check that “Fit to Page” or any scaling option is disabled in the print dialog. Print at exactly 100% scale (no scaling).
- Horizontal measurements are correct but vertical are off (or vice versa)
- The paper feed calibration may be incorrect. Look for a “paper feed adjustment” setting in your printer’s maintenance menu.
- Measurements are off near the edges but correct in the center
- This may indicate lens or drum distortion on laser printers. Contact the manufacturer for service if accuracy is critical.
