The receiving program sets the first constraints
Before choosing a family, collect the recipient’s current instructions and any institutional letterhead template. A recommendation letter is written by its recommender, with a different information role from the applicant’s résumé or cover letter. Keep the writer’s name, relationship and supporting examples easy to locate. Do not shrink the body merely to make an overlong draft resemble an attractive one-page specimen.
Distinguish general suggestions from explicit requirements
Microsoft’s recommendation-letter guide suggests professional options such as Aptos, Calibri or Arial at 11–12 points. A specific recipient can require something narrower: the Goldwater Scholarship’s instructions specify 12-point type, a two-page limit and a signed PDF, alongside other rules. Those are different kinds of guidance. Apply the actual recipient’s requirements rather than treating a general suggestion as permission to ignore them.
Compare the letterhead and a complete body paragraph
Prepare a realistic opening, two evidence-based paragraphs and a closing with the writer’s title. Check that an institutional header does not crowd the first paragraph, and that a long name or organization wraps cleanly. Keep emphasis restrained so the narrative remains the focus. Compare body size and paragraph spacing together rather than judging an isolated heading with no surrounding text.
Preserve a clear export and handoff
Follow the required submission format and review the completed letter as a whole, including the final paragraph and signature area. Keep the original editable file so corrections do not require reconstructing a PDF. The PDF-embedding guide explains how font resources affect portability; it does not prove that a letter meets a program’s requirements. Use the letterhead and reading guides for broader composition choices without replacing the recipient’s instructions.
Your questions, answered.
Is there one best font for every recommendation letter?
Begin with the recipient’s rules and institutional template. General Word examples are options, not a universal mandatory family.
Should I make the font smaller to satisfy a page limit?
Preserve the required size and revise the content or layout within the permitted format. A page limit does not override an explicit type-size requirement.
