PDF Cut Off When Printing? Fix Page Size, Scaling, and Margins
The symptom is familiar: the page looks perfect on screen, but the printout is missing the last line, the right edge of a table, or the page numbers at the bottom. The screen is not lying and neither is the printer — they are simply working from different page sizes. Before changing anything, check the document's actual dimensions in your viewer's document properties. A4 paper is 210 by 297 millimeters; US Letter is 215.9 by 279.4. Letter is wider and shorter than A4, so each format prints the other with something shaved off unless the software compensates.
Diagnosis one, the classic: an A4 document sent to a Letter printer or vice versa. This is overwhelmingly the cause when a colleague overseas prints your file and the bottom or side content vanishes. The fix lives in the print dialog, not the file: choose the option named 'Fit to page' or 'Shrink to printable area' instead of 'Actual size'. The whole page then scales down a few percent to fit the loaded paper. If you produce documents for an international audience, keep bottom and side margins generous so either paper size swallows the difference gracefully.
Diagnosis two: scaling is set to 'Actual size' and the page really is bigger than the paper. Architectural drawings, posters, and spreadsheet exports often have pages far larger than A4. Printing them at 100 percent guarantees cropping. Either scale to fit and accept smaller text, or print a selected region at full size. For the second option, PdfWill's crop tool lets you trim the page to exactly the region you need before printing; and if a page prints sideways with content running off one edge, rotate it to the correct orientation first, since a landscape page forced onto portrait paper is another classic cropping cause.
Diagnosis three: printer hardware margins. Most office printers cannot print the outer three to five millimeters of the sheet, so a PDF with content running to the very edge — full-bleed backgrounds, decorative borders, footers set too low — loses that strip on every printer regardless of settings. If the border matters, scale to around 95 percent. If the ragged unprintable edge itself is the annoyance, crop the decorative bleed away so the meaningful content sits comfortably inside the printable area. Documents destined for professional printing should keep bleed; documents for office printers should not.
When you control the source document, prevent the problem instead: set the page size deliberately before exporting, and pick the size your audience actually loads in their trays. As a last-resort rescue for a stubborn file that refuses to print correctly, convert the page with PDF to Image and print the image — image printing dialogs scale to paper by default, which sidesteps PDF scaling quirks entirely, at the cost of text sharpness.
