Why Does My PDF Cut Off Text?

Almost always a margin, page size, or export settings issue — here’s what’s causing it and how to fix it

---

Opening a PDF and finding text cut off at the edges, truncated at the bottom of pages, or disappearing entirely in certain areas is a frustrating problem that has several distinct causes.

The fix depends on where the text is being cut — edge cutoffs point to margin or page size issues, bottom cutoffs point to content overflow, and inconsistent cutoffs point to font or rendering problems.

Here’s how to identify which one applies and correct it.

The Page Size Doesn’t Match the Content

This is the most common cause of text being cut off in PDFs. When a document is created at one page size — A4 for example — but exported or printed to a different size — US Letter — content that fits the original page may extend beyond the margins of the target page size. Text that appeared at the right edge of an A4 document gets cut off on a slightly narrower Letter page.

A4 is 210 x 297mm (8.27 x 11.69 inches). US Letter is 216 x 279mm (8.5 x 11 inches). A4 is taller but narrower than Letter. Content designed for one that’s printed to the other will lose content at either the sides or the bottom depending on which size mismatch is in play.

The fix: When exporting or printing to PDF, make sure the page size in the export settings matches the page size of the original document. In most applications, go to the print or export dialog and check the paper size setting — change it to match your document’s actual page dimensions.

Margins Are Set Too Small or to Zero

Text that runs too close to the page edges gets cut off when the PDF is rendered, printed, or viewed on certain devices. This happens particularly with content that was designed with very small or zero margins — text that reaches the edge of the page boundary often clips in PDF rendering.

Most printers and PDF viewers have a non-printable area — a small border around the page edges where content doesn’t render. Even if your document shows text right to the edge on screen, that edge content may be cut off in the PDF output.

The fix: Increase your document margins. In word processors and design applications, go to page or document settings and set margins to at least 0.5 inches (12mm) on all sides. For professional printing, 0.75 to 1 inch margins are standard. Republish or re-export the PDF with the adjusted margins.

The PDF Viewer Is Clipping the Display

Sometimes the text is in the PDF correctly but the viewer is clipping it — a display issue rather than a document issue. PDF viewers that don’t handle certain page sizes or zoom levels correctly can make text appear cut off when the underlying file is actually fine.

Test by opening the PDF in a different viewer. If the text appears correctly in Adobe Acrobat but is cut off in your browser’s built-in PDF viewer, the viewer is the problem. Try zooming out in the viewer — sometimes content that appears cut off is simply outside the current viewport and becomes visible at a lower zoom level.

Also check whether the viewer is set to crop or trim the PDF. Some viewers have a Crop Pages or Trim Margins setting that visually removes content near the edges. In Adobe Acrobat, go to View → Page Display and check for any cropping settings.

The PDF Has Crop Marks or Bleed Settings Applied

Professional PDF files sometimes have crop marks, bleed areas, and trim boxes applied for commercial printing. These settings define different boundaries within the PDF — the trim box defines where the page is cut, the bleed box extends slightly beyond for print safety, and the media box defines the full physical page.

If a PDF viewer is displaying the trim box rather than the media box, content outside the trim area appears cut off. This is correct behavior for print-ready PDFs but confusing when viewing on screen.

In Adobe Acrobat: Go to File → Properties → Description and check the page dimensions. Go to View → Page Display → Show Art, Trim and Bleed Boxes to see which box boundaries are active. Adjust the view to show the full media box rather than just the trim box.

Text Overflows the Text Box in the Source Document

In documents created with text boxes — particularly in PowerPoint, InDesign, Publisher, and similar layout applications — text that exceeds the size of the text box gets cut off when exported to PDF. The text exists in the source document but the text box container stops it from being rendered beyond its boundaries.

This is common when template text boxes have fixed sizes and content is added that exceeds those sizes. The overflow text is visible in some editing views but disappears in the exported PDF.

The fix: Go back to the source document. Select the text box containing the cut-off content. Resize the text box to accommodate the full text, reduce the font size to fit within the existing box, or enable auto-fit if the application supports it (PowerPoint has a Shrink Text on Overflow option). Re-export the PDF after making the adjustment.

Font Embedding Issues

Fonts that aren’t embedded in the PDF can cause text rendering problems when the PDF is opened on a system that doesn’t have that font installed. The PDF viewer substitutes a different font — and font substitution changes character widths, line heights, and text flow. Content that fit correctly with the original font can overflow and get cut off when a wider or taller substitute font is used.

Check font embedding: In Adobe Acrobat, go to File → Properties → Fonts. Any font listed without “Embedded” or “Embedded Subset” next to it may cause rendering problems on other systems.

The fix when creating the PDF: Embed all fonts during export. In most PDF export dialogs, look for a fonts or advanced settings section and enable Embed All Fonts. In Adobe products, this is typically under Output → PDF/X settings or the Advanced section of the PDF export dialog.

The Printer Is Scaling the PDF

When printing a PDF, printer drivers sometimes scale the content to fit their own paper size or printable area — this can push content outside the visible area and effectively cut it off. A PDF designed at exact Letter size printed to a printer that auto-scales to 95% to fit its margins will shift all content slightly inward, potentially cutting off content near the edges.

In the print dialog: Look for a Page Sizing and Handling or Print Size option. Make sure it’s set to Actual Size or 100% rather than Fit to Page or any automatic scaling option. Fit to Page shrinks the content to fit within the printer’s margins, which changes where text falls.

In Adobe Acrobat’s print dialog, select Actual Size under Page Sizing to prevent automatic scaling.

Content Is Outside the Page Boundary in the Source

In design applications like InDesign, Illustrator, or even Word, it’s possible to position content partially or fully outside the page boundary — visible on the pasteboard or scratch area in the application but not within the actual page. When exported to PDF, this content is clipped at the page boundary.

The fix: In the source application, check whether any text frames, images, or content elements extend beyond the page boundary. In InDesign, enable View → Extras → Show Frame Edges to see the boundaries of all content elements. Move any content that extends beyond the page back within the page boundary and re-export.

Browser-Based PDF Creation

Printing to PDF from a browser — using the browser’s built-in print to PDF function — sometimes cuts off content because web pages and PDFs handle page breaks and content flow differently. A webpage that scrolls continuously doesn’t have natural page breaks, and the browser’s PDF creator has to impose them — sometimes cutting through content mid-paragraph, mid-image, or mid-table.

Adjust the scale when printing from a browser. In the browser’s print dialog, reduce the scale from 100% to 90% or 85% to bring edge content away from the margins. Also check the Margins setting — use Default or Custom margins rather than None, which removes all margin padding and causes edge clipping.

Some browsers handle this better than others — if Chrome’s print to PDF is cutting content, try Firefox or Edge’s implementation.

Corrupted PDF File

A corrupted PDF file can cause text to display incorrectly — appearing cut off, missing entirely, or garbled. Corruption can happen during download, during file transfer, or if the PDF was created by a malfunctioning application.

Test the file by opening it in multiple PDF viewers. If it appears correctly in one viewer but cut off in another, the viewer is the issue rather than the file. If it appears cut off in every viewer, the file may be corrupted.

Try re-downloading the file if it came from the internet. Try regenerating the PDF from the source document if you have access to it. If the file was emailed, ask the sender to resend it — email transmission occasionally corrupts attachments.

A Quick Checklist

Match your symptom to the most likely cause:

• Text cut off at right or left edges — page size mismatch or margins too small
• Text cut off at bottom of pages — content overflow from page size difference or text box overflow
• Text cut off inconsistently across the document — font embedding issue or text box overflow in source
• Cut off only when printing — printer scaling set to Fit to Page instead of Actual Size
• Cut off only in one viewer — viewer display or crop settings
• Cut off in a web page printed to PDF — reduce browser print scale to 90% or lower
• Cut off in text boxes in source document — resize text boxes or enable shrink text on overflow

The Bottom Line

PDF text cutoff is almost always a page size mismatch, a margin setting, or a text box overflow in the source document. Checking that the export page size matches the document page size and that margins are set to at least 0.5 inches resolves the majority of cases.

For text boxes specifically — common in PowerPoint and layout applications — the cut-off text exists in the document but is hidden by the container’s boundaries. Going back to the source and resizing the text box fixes it at the root rather than working around it in the PDF.

The text is almost always there — something is just hiding it at the boundary. Find the boundary that’s too small and expand it.
