Question details

The user is experiencing a slight font size discrepancy where text in a PDF converted from a Word document displays as 0.04 points larger when viewed in third-party PDF editors.

Why Does PDF Font Size Differ from Word by 0.04 Points?

Product: Microsoft Word, Adobe Acrobat, PDF-XChange
Device & OS: not provided
Scenario: Saving a Microsoft Word document as a PDF and reviewing the exact font sizing and text formatting in a PDF editor.
Observed behavior: When selecting text in the resulting PDF, the font size displays as exactly 0.04 points larger than the originally set value in the Word document.

Before you start

Ensure your word processor and PDF reader are updated to their latest versions, as minor font rendering and rounding anomalies are frequently patched in software updates.

Solution 1Recommended

Isolate the PDF Conversion and Display Issue

Determine whether the font size difference is caused by the specific document, the conversion engine, or the PDF viewer's rounding mechanics.

A 0.04 point difference often stems from how different software engines handle floating-point math and unit conversions (such as points to twips) during the PDF creation process. Following these troubleshooting steps will help isolate the root cause.

Verify your Microsoft Office version

Open Microsoft Word, navigate to 'File' > 'Account', and review the Product Information. Taking a screenshot of this version helps when seeking support from Microsoft or Adobe.

Test with a newly created document

Create a brand new Word document, type sample text using standard system fonts like Arial or Calibri, and save it as a PDF. This helps rule out file-specific corruption.

Compare multiple PDF readers

Open the exported PDF in different applications like Adobe Acrobat, PDF-XChange, and your web browser. Check if the 0.04 point difference is unique to one specific PDF reader's property inspector.

Negligible Print Impact: A 0.04 point difference in typography is completely imperceptible to the human eye and will not affect the layout, pagination, or printed quality of your document.

Frequently Asked Questions

Why does a PDF viewer show a slightly different font size than Word?

This happens due to floating-point rounding errors during conversion. Word calculates sizes internally using 'twips' (1/20th of a point), while PDF formats often use different internal metrics. When translating between the two, a tiny fractional difference like 0.04 points can appear in the viewer's properties.

How can I prevent font sizes from changing when making a PDF?

Instead of using the standard 'Save As PDF' option, try using a dedicated PDF printer driver. Navigate to File > Print and select 'Microsoft Print to PDF' or 'Adobe PDF'. This processes the document as a strict print job and often locks in exact dimensions.

Does a 0.04 point font size change affect page layout?

No. The 0.04 point discrepancy is microscopic and generally only visible in the property inspector of the PDF editing software. It does not alter line breaks, page counts, or visual paragraph spacing.
