Cover letter font size usually looks right at 11–12 pt, with 10 pt reserved for tight one-page layouts that still read well on paper.
If your cover letter looks hard to read, the content doesn’t get a fair shot. Font size is a small choice that changes the whole feel: line length, white space, and how fast a reader can skim.
This guide walks you through the font-size range hiring teams expect, when to go smaller, and a quick set of checks so your letter looks sharp in PDF, email, and applicant systems.
Font Size Options By Use Case
| Use Case | Font Size Range | Notes That Prevent Reformatting |
|---|---|---|
| Standard one-page letter (PDF upload) | 11–12 pt | Stick to a common font; match your resume typeface and keep headers only slightly larger. |
| ATS with a plain upload box | 11–12 pt | Use simple spacing and left alignment; avoid text boxes and columns that can shift. |
| Space-tight letter that still reads clean | 10–11 pt | Trim text first; use 10 pt only after a print check and only with a readable font. |
| Email body cover letter | 11–12 pt | Default email font is fine; keep it plain and rely on short paragraphs and clear breaks. |
| Academic or career-office formats | 10–12 pt | Many campus career offices set 10–12 as the safe zone; keep the full page consistent. |
| Printing on office paper | 11–12 pt | Do a real print test; what looks fine on screen can turn light or cramped on paper. |
| Accessibility-friendly readability | 12 pt | Pick 12 pt with generous spacing when you can; it feels calm and readable. |
| Formal letterhead with contact block | 11–12 pt | Keep the body consistent; let the letterhead carry branding so the body stays simple. |
Font Size Cover Letter Rules For ATS And Print
Hiring managers and recruiters read fast. They scan for fit, then decide if the details are worth their time. If the type is too small, you force extra effort. If it’s too big, the page can feel padded.
Most career offices and hiring resources land on the same range: 10–12 point for body text, with 11 or 12 as the default for a one-page letter. That range also plays nicely with common résumé fonts and typical printer settings.
Why 11 Or 12 Point Works So Often
At 11–12 pt, you get a steady rhythm: readable lines, balanced white space, and fewer weird breaks when your document is opened on another machine. It also reduces the urge to squeeze margins or jam in extra sentences.
It’s also safer for applicant systems. Many ATS platforms display PDFs in a small viewer. A font that reads well in a narrow viewer is the same font that reads well on a phone.
When 10 Point Can Still Be A Good Call
Ten point can work if your letter is already tight and you only need a small nudge to keep it on one page. The catch is readability. Ten point in a dense serif can look like a wall of gray, while 10 point in a clean sans serif can still feel fine.
If you move to 10 pt, do a print test and a zoomed-out screen test. If you squint, your reader will too.
Pick A Typeface That Stays Clean
Font size is only half the story. The typeface changes how big the letters feel at the same point size. Two fonts set to 11 pt can look wildly different in weight and spacing.
For most job applications, stick with a standard font that hiring teams see every day. Matching your résumé font keeps the application package consistent, which helps it feel intentional.
Safe Font Choices That Rarely Cause Issues
- Calibri or Arial for a modern, simple look
- Times New Roman or Georgia for a classic business feel
- Helvetica when you want a clean sans serif and your system has it
Skip decorative fonts, script styles, and fonts that mimic handwriting. They can look playful, and they can render oddly when converted to PDF.
Spacing And Margins That Keep The Page Readable
Once you settle on font size, spacing decides whether the page feels airy or cramped. Your goal is a page that reads like a letter, not like a dense report.
Start with single spacing in the body, then leave a blank line between paragraphs. If your lines feel tight, bump the line spacing to 1.15 and keep everything else the same.
Margin Numbers That Work In Most Templates
One-inch margins are a safe default. If you’re fighting the page, you can tighten margins a little, but keep them even on all sides. A margin that’s too small can make a printed page look crowded near the edges.

Line Length And White Space Checks
A cover letter reads best when each line isn’t too long. If your lines stretch across the full width with small type, the reader’s eyes can lose their place. If lines are too short, the page starts to look choppy.
As a quick self-check, zoom your PDF to fit width. If the body looks like a block with tiny gaps, increase font size or spacing before you touch margins.
How To Fit On One Page Without Shrinking The Text
Most cover letters should stay on one page. When you’re at one page plus a few lines, the temptation is to drop the font size. Try content edits first. They carry more impact than squeezing typography.
Edits That Save Space Without Killing Clarity
- Cut the soft opener and lead with the role and your match in the first two lines
- Swap long phrases for shorter verbs: “worked on” instead of “was responsible for working on”
- Remove repeated skill lists; keep one strong proof point per paragraph
- Drop filler words and keep sentences tight
If you do all that and still need room, a small line-spacing tweak is usually cleaner than switching from 12 pt to 10 pt.
Email And Form Submissions
Sometimes there’s no upload. The cover letter goes straight into an email or a web form. In those cases, the viewer controls the font, not you, so you win by staying plain and structured.
Write short paragraphs, keep one idea per paragraph, and use a simple sign-off. Avoid fancy bullets, tables, and columns in email text because they can break on mobile.
If you’re writing in Word first, set your draft to 11 or 12 pt so it’s easy to edit, then paste into the email and re-check spacing. Microsoft’s notes on cover letter formatting practices line up with that 11–12 pt norm for body text.
ATS And PDF Checks Before You Hit Send
A cover letter can look perfect in Word and still shift after export. Different PDF creators embed fonts in different ways, and some ATS viewers scale the page oddly.
Run a quick three-step check every time you export:
- Open the PDF on your computer and zoom to 100%. Make sure spacing looks consistent.
- Open the same PDF on your phone. If you need to pinch-zoom to read the first paragraph, the font is too small.
- Print one copy in black and white. Check that headers, body text, and your signature line look balanced.
Common Font-Size Problems And Clean Fixes
| What You See | Why It Happens | Fix That Keeps The Letter One Page |
|---|---|---|
| Body text looks tiny in an ATS viewer | The preview pane is small and scales down the page | Use 11–12 pt, keep margins reasonable, and avoid light fonts |
| Lines wrap in weird places after PDF export | The font isn’t embedded or a fallback font loads | Export as PDF with font embedding on, then re-open and verify |
| Letter spills to a second page by two lines | Paragraph spacing or headers take more room than expected | Tighten paragraph spacing slightly or cut one weak sentence |
| 12 pt feels bulky and pushes content down | The typeface runs large at the same point size | Keep 12 pt, switch to a slimmer standard font like Calibri |
| 10 pt looks gray and dense | Serif font with heavy stroke weight | Move to 11 pt or change to a clean sans serif |
| Header is huge compared to body | Template defaults to big heading styles | Set header to 1–2 pt larger than body, not a full jump |
| Spacing feels inconsistent between paragraphs | Mixed styles got pasted in from another doc | Select all text and apply one style for body and one for headers |
| PDF looks fine, printed copy looks faint | Light font weight and low printer contrast | Use a normal font weight, avoid light gray text, and print again |
Make Your Letter Easy To Scan In 20 Seconds
Even a well-sized cover letter can feel slow if the page is dense. The fastest way to boost readability is structure: a direct first paragraph, two short proof paragraphs, and a close that asks for the next step.
Try this layout:
- Paragraph 1: Role, where you found it, and one line on your fit.
- Paragraph 2: One achievement tied to the job’s top need.
- Paragraph 3: Second achievement, different skill area, still tied to the posting.
- Paragraph 4: Close with availability and a polite prompt for an interview.
With this structure, 11–12 pt almost always lands cleanly on one page without tricks.
Final Pre-Send Checklist
Run this checklist once, then send with confidence. It takes five minutes and saves a lot of rework.
- Body text is 11–12 pt in a standard font; 10 pt only after a print check.
- Font matches the résumé, and the full letter uses one body style.
- Margins are even, and the page doesn’t look cramped at the edges.
- Paragraph spacing is consistent, with a clear blank line between blocks.
- PDF opens cleanly on desktop and phone with no odd line wraps.
- File name is clear: Lastname-Role-CoverLetter.pdf.
If you keep the body at 11 or 12 pt, stick with a familiar font, and run the quick PDF checks, your cover letter will look polished in almost any system. If you’re tempted to shrink the type, cut one weak sentence first. Your reader will thank you.
Quick line for editing: font size cover letter defaults to 11–12 pt; smaller sizes work only when readability stays strong.
And yes, the same logic applies when you tweak the font size cover letter for a second role. Keep your base template at 11–12 pt, then trim content per posting instead of changing type each time.
