Why is my PDF cut off when printing? Check paper size and scaling

If a PDF looks complete on screen but the printer cuts off an edge, the source page is often fine. The usual causes are a paper-size mismatch, a print-area limit, or a scaling option that enlarges the page. Check those settings before editing the PDF.

First, separate missing content from a print setting

Open the PDF at 100% and inspect the page edge. If the text or graphic is visible in the PDF but absent on paper, the print path is the likely problem. If it is missing in the PDF itself, return to the source document or export step.

Use this three-check sequence

1. Match paper sizes. Compare the PDF page size with the paper loaded in the printer. A letter page sent to A4 paper, or the reverse, can change the printable area.
2. Choose fit or actual size deliberately. “Actual size” keeps the page scale but may clip content outside the printer’s margins. “Fit” reduces the page so the full page fits inside the printable area. Read the preview before printing.
3. Check orientation and printable margins. A landscape page printed as portrait can lose the right edge. Borderless printing is a printer capability; if it is unavailable, a narrow edge may remain outside the printable area.

Worked example: a clipped right margin

Suppose a two-page report is 8.5 × 11 inches and the printer is set to A4 with “actual size.” The preview shows the rightmost 0.2 inches outside the printable region. Switch the paper setting to Letter if that is the loaded paper, or use “Fit” and confirm the preview shows the complete page. Keep the PDF unchanged until the preview matches the intended output.

If the PDF itself is too wide

When the page content really extends beyond the intended page, edit a copy and inspect the result at the edge before printing. AlphaPDF’s PDF editor can help you make a controlled copy for review. It does not change your printer’s paper size or margin limits, so recheck the print preview after any edit.

Final print checklist

• PDF page size matches the loaded paper.
• Orientation matches the page.
• Preview shows all four edges.
• Scaling choice is intentional.
• A test page confirms the result before the full packet.

For printer-specific behavior, use the printer manufacturer’s instructions; printable margins and borderless options vary by model.
