Quick answer
Compare the PDF page size, selected paper size and scaling mode. Actual size preserves the document’s physical dimensions; Fit scales it to the printable area.
Understand the problem before changing anything
An A4 document on Letter paper is not a one-to-one match. Even matching paper has non-printable margins on many printers. Decide whether exact measurement or complete visible content matters more for this job.
Step-by-step checks
Inspect document dimensions
Check the PDF page size and whether pages use mixed sizes. Confirm the paper physically loaded in the printer.
Choose a scaling mode
Compare Actual size, Fit and Shrink oversized pages in Acrobat’s Size options. Read the preview rather than assuming 100% fits.
Check driver scaling
Remove unintended enlargement, borderless scaling or extra pages-per-sheet settings in the printer properties.
Use a measured test
Print a page containing a known dimension if exact scale matters. Measure the paper output instead of judging only on screen.
Check all page types
For mixed portrait, landscape or paper sizes, preview more than the first page before printing the whole document.
What to avoid
Actual size may crop content outside the printable area. Fit may alter the dimensions of a pattern, form or technical drawing.
How to verify the result
For exact-size work, record the measured result and settings. For reading copies, confirm all content is visible and comfortably readable.
Keep the source PDF and verify the delivery copy
Keep the original PDF unchanged while testing viewer, print or conversion settings. Check the page count and whether the file contains normal digital text, scanned images, annotations or component attachments. These features affect what different viewers can display, search, print or preserve.
Choose a representative page rather than judging the entire document by its cover. Include a page with small text, a diagram and any comments relevant to the task. Browser PDF viewers and desktop applications have different capabilities, so use the intended reader for the operation rather than assuming every viewer will expose the same controls.
Check the final output separately from the on-screen editing view. For a printout, compare paper size, orientation and scaling with the preview. For a converted or compressed copy, inspect text, images, page order and searchability. Save under a different filename and verify the uploaded or shared preview where possible. Handle confidential documents with approved tools; an online converter receives the file you upload, even when the conversion itself looks routine.

Common question
Is 100% screen zoom the print scale?
Not necessarily. Screen zoom and print scaling are separate controls. Check the print dialog and physical output.
