Configure Word Processor Templates for Compliance
Set up your document styles correctly in your word processor before converting the file to a PDF to ensure all compliance checks are met.
Most compliance errors stem from incorrect source document settings. Fixing the page layout, font styles, and spacing in your original document before exporting to PDF is the most reliable method.
Navigate to your Page Layout or Document Settings menu and set the page size to standard U.S. Letter (8.5 x 11 inches).
Set the top, bottom, left, and right margins to at least 0.5 inches to meet strict boundary rules.
Highlight all text and choose an approved font such as Arial, Helvetica, Palatino Linotype, or Georgia. Ensure the font size is set to at least 11 points.
Adjust line spacing according to agency guidelines, ensuring there are no more than six lines of text per vertical inch.

Verify Final Output with PDF Preflight Tools
Use advanced PDF software tools to check the final output for hidden formatting errors before submission.

Frequently Asked Questions
What are the approved fonts for NIH grant applications?
NIH typically requires using Arial, Helvetica, Palatino Linotype, or Georgia. The font size must be exactly 11 points or larger to ensure readability and compliance during the review process.
What are the standard margin requirements for federal PDFs?
Most federal guidelines mandate a minimum of half-inch (0.5 inch) margins on all sides (top, bottom, left, and right) for standard U.S. Letter pages. No text or images should extend into this margin area.
How do I ensure my character density meets the requirements?
Federal character density rules generally dictate no more than 15 characters per linear inch. Consistently using the approved typefaces (like Arial or Georgia) at 11 points or larger will automatically keep your document within this acceptable density limit.
