Match the paper size
Check whether the file is made for Letter, A4, or another size. Select the matching paper size in your print dialog.
Use actual size when accuracy matters
If a pattern, label, or worksheet needs exact sizing, choose actual size or 100 percent scale. Avoid fit-to-page unless the product notes recommend it.
Check orientation
Some files are portrait, and others are landscape. If a page looks cropped in preview, check the orientation setting before printing.
Use a test page
Print one page first. A quick test can save paper and help you choose the right setting for the full file.
Practical next step
If you are new to printable files, start with one free PDF, save it in a clearly named folder, and print one test page before using the full file.
