Print Calibration Sheet
Print known reference lengths to check whether your printer preserves physical dimensions. Use this page before relying on a printable ruler, cutting template or other output whose actual size matters.
Understanding the layout
A correctly dimensioned PDF can still be printed incorrectly when a driver fits it to a page or applies a borderless expansion. Compare the marked 100 mm and four inch lengths with a trusted ruler. The one inch square adds a vertical check: both its width and its height should measure 25.4 mm. Checking both directions helps detect unequal horizontal and vertical scaling.
Using the sheet
Choose the same paper, printer and print settings that you intend to use for the final template. Download the PDF and select Actual size or 100%. Measure the marked reference from its intended endpoints, not from the outer edges of thick strokes. If the result is wrong, correct the print settings and repeat the check before using another dimensioned sheet.
Choosing the settings
Paper size must match the loaded paper. Orientation can help fit the reference layout but does not change the known lengths. PNG exports include a chosen pixel density, yet image printing applications may handle physical size differently; PDF is the clearer starting point for a scale check. Keep a note of the settings that produced a correct result.
A practical example
Download the default calibration PDF and print it at 100%. Measure the 100 mm line, the four inch line and both sides of the square. Four inches is 101.6 mm, so that line should be slightly longer. Both square dimensions should be 25.4 mm. Confirm these checks before using an exact template.
Before you print
This sheet checks a print workflow; it does not certify a printer, diagnose every mechanical problem or provide traceable metrology. Paper distortion and measurement technique still matter. Repeat the check when changing relevant print settings.

Common question
Should I compensate by guessing a new scaling percentage?
First remove Fit, Shrink or borderless expansion and confirm the paper size. Use an independently verified workflow rather than guessing around an unknown setting.
