Print a simple test sheet with a 1-inch square, 2-inch bar, 100 mm bar, 50 mm bar, and 10 cm grid. Measure the printed result, then calculate the correction scale to use when exact-size worksheets, flashcards, labels, rulers, or poster tiles matter.
For an exact-size test, open the browser print dialog and choose Actual Size, 100%, or No scaling. Print one page first before batch printing classroom materials.
After printing, measure one reference shape with a physical ruler. Enter the measured result below to estimate whether your printer is shrinking or enlarging the page.
Print this page at Actual Size / 100%. Measure the reference shapes below. If they are not exact, adjust your print scale or printer settings before printing exact-size pages.
