What Font to Use for a Cover Letter (ATS-Safe)

6 min read

You're not picking a font to impress a designer. You're picking one that survives export, matches your resume packet, and pastes cleanly into plain text. Most applicants overthink typeface and skip the two-minute paste test that actually matters.

If you've already locked resume formatting, don't open a second design rabbit hole tonight. Copy the resume family, set body text to 11 or 12 pt, and move on to content. For point size and margins, pair this page with HireFlow's cover letter font size guide .

Check your resume for free after the letter export passes the paste test. Parsing on the CV matters more than serif versus sans on the letter, but mismatched fonts still look sloppy when a recruiter opens both attachments in Greenhouse.

What ATS actually reads from your font choice

Applicant tracking systems do not score Helvetica higher than Times New Roman. They extract text strings from your upload. When a font embeds as curves or lives inside a text box, extraction fails and the letter becomes a blank attachment in the profile preview.

The font question is really a selectable-text question. Standard system fonts in Word or Google Docs export cleanly. Canva display fonts, script headers, and icon bullet fonts often look fine on screen and die on import.

Recruiters skim letters on phones inside Greenhouse. Calibri and Arial stay readable at 11 pt. Thin display weights wash out in preview thumbnails. That is a human read problem, not an ATS rank problem, but it still costs you seconds on the skim.

For conservative finance, law, or government-adjacent roles, Times New Roman or Garamond signal formality. For tech and ops, Calibri or Arial feel neutral. The wrong choice is rarely serif versus sans. It is decorative type mixed with a plain resume.

Pick and test your cover letter font in four moves

You can finish this tonight in under ten minutes. Work on the same file you plan to attach.

Step 1: Copy the resume font family

Open your resume export. Note the body font. Set your cover letter Normal style to that same family before you write a single line. If the resume uses Calibri 11 pt, the letter uses Calibri 11 or 12 pt, not Georgia or a template accent font.

Before: Resume in Calibri, letter header in Pacifico script.
After: Both files in Calibri. Name line bold at 14 pt, body at 11 pt.

Step 2: Set one size band and stop tweaking

Body text at 11 or 12 pt. Name at 14–16 pt in the same family. Garamond often needs 12 pt to match the visual weight of Calibri 11. Do not shrink margins to fit a decorative face. Cut a sentence instead.

Before: Three fonts: script name, narrow body, serif quote box.
After: One family, bold for name and date line only.

Step 3: Export text-based PDF or DOCX

I've screened thousands of uploads in Workday, and the letter that survives is boring on purpose: Calibri or Arial, no text boxes, no icon bullets. Export from Word or Google Docs. Avoid browser Print to PDF when it rasterizes the page.

If the portal accepts DOCX, test that format too. Some teams preview DOCX more faithfully than PDF subsetting.

Step 4: Run the paste test

Open the export, select a paragraph, paste into Notepad. If nothing pastes, the font failed regardless of how polished the PDF looked. Rebuild in Word with Arial, re-export, and test again.

COVER LETTER FONT (2-minute lock)

1. Match resume family: [Calibri / Arial / Times New Roman / Garamond]
2. Body: 11 or 12 pt | Name: 14–16 pt bold, same family
3. Remove script, icon, and display fonts
4. Export text-based PDF or DOCX from Word/Docs
5. Paste test: select paragraph → Notepad → text must appear
6. Upload to Workday/Greenhouse → check preview thumbnail
              

Font traps that break export even when the letter looks fine

Script or calligraphy for your name. Pretty on Instagram. Parsers often store garbled characters or skip the header block entirely.

Icon fonts for contact rows. Phone and LinkedIn icons do not paste. Write Phone: and LinkedIn: as plain labels. See why resume icons cause rejection for the same failure on CV uploads.

Second display font for the company name. Bold and title case are enough. A second typeface adds risk without helping recruiters.

Canva custom fonts without embed check. Rebuild in Word with Calibri when paste test fails. Template polish is not worth a blank letter field.

Calibri Light for body text. Light weights look washed out in Greenhouse previews and on phone screens. Use regular Calibri.

Match letter and resume before upload

After the paste test passes, run the resume through a checker with the job description. You're confirming the CV parses cleanly, not chasing a magic font score on the letter.

Use HireFlow's free ATS resume checker on the posting you are targeting. Fix layout gaps on the resume first.

Draft the letter body in generate a cover letter from the same posting, then paste into your Word file with the font you locked in step one. Matching titles and dates across both files beats a prettier typeface mismatch.

Lock the font and send

What font to use for a cover letter is a short answer: Calibri or Arial at 11–12 pt for most roles, match your resume, skip decorative faces, and confirm selectable text with a Notepad paste. Workday does not pick winners by serif. Broken extraction does.

Set Normal style once, export, paste test, upload. Then spend your energy on two proof bullets that match the posting, not on hunting a rare typeface.
