Printer Scaling Test
Print a known-size test pattern to check whether your printer outputs documents at the correct physical scale.

Scaling test sheet
The preview shows the seven sections included on the printable test sheet.
1 100 × 100 mm square
100 × 100 mm. Measure both sides with a physical ruler.
2 50 × 50 mm square
3 Horizontal 100 mm reference
4 Vertical 100 mm reference
5 Metric ruler
6 Inch reference
1 inch = 25.4 mm
7 Measurement grid
Each square is exactly 10 mm × 10 mm.

Reference
Quick interpretation
| Result | What to check |
|---|---|
| 100 mm measures 100 mm | Scale matches the reference |
| 100 mm measures less | Output was reduced |
| 100 mm measures more | Output was enlarged |
| Horizontal and vertical differ | Check paper feed, driver settings, and printer behavior |
| Scale is correct but edges clip | Check printable-area limitations |
| Scale is correct but content is shifted | Check positioning or alignment |
Scaling vs Margin vs Alignment
- Scaling checks whether dimensions are printed at the intended physical size.
- Margin checks how close the printer can print to each paper edge.
- Alignment checks whether content is positioned or skewed correctly.
Important
Always measure the physical print with a ruler. Screen size is not a reliable reference for printer scaling.
Use the same paper size in the page, browser print dialog, and printer driver.
This is a measurement test only. Scaling can be affected by browser print settings, PDF viewers, printer drivers, paper-size mismatches, borderless expansion, paper behavior, and printer-specific settings. This test cannot determine whether a particular hardware component is faulty.

FAQ
Scaling test questions
Why is my printer printing everything smaller than the original?
The print dialog may be reducing the page with settings such as Fit to Page, Shrink to Fit, or Fit to Printable Area. Set the print scale to 100% / Actual Size and make sure the selected paper size matches the test page.
How do I print at actual size on my printer?
Select the correct paper size and set the print scale to 100% or Actual Size. Disable Fit to Page, Shrink to Fit, and similar automatic scaling options.
How can I check if my printer is printing to scale?
Print the scaling test at 100% / Actual Size, then measure the 100 mm reference with a physical ruler. If it measures 100 mm, that reference was printed at the intended scale.
Why does my 100 mm test measure less than 100 mm?
A common cause is automatic scaling in the browser, PDF viewer, or printer driver. Check that the scale is set to 100% / Actual Size and that Fit to Page or Shrink to Fit is disabled.
Why does my printer print larger than the correct size?
Check whether the print scale is above 100% or whether a printer, driver, PDF viewer, or borderless setting is enlarging the output. Reprint with 100% / Actual Size and borderless mode disabled.
Why are my horizontal and vertical measurements different?
Different horizontal and vertical measurements can indicate differences in paper feeding, driver settings, media behavior, or printer mechanics. First confirm the paper size and print scale, then repeat the measurement.
Does Fit to Page change the printed size?
Yes. Fit-to-page settings can resize the entire document so it fits within the printer's printable area. This can make a known-size square, ruler, template, or pattern print smaller than its intended dimensions.
Why does my print have the correct scale but the edges are cut off?
Correct scaling does not guarantee that every part of the page is printable. Most printers have a non-printable area near the paper edges. Use the Printer Margin Test to check how close your printer can print to each edge.
