Cover Letter Font Size and Spacing: The Complete Formatting Guide (2026)

Quick answer: A cover letter should use 10 to 12 pt body text, single to 1.15 line spacing, a blank line between paragraphs, and standard 1-inch margins, all on a single page of roughly 250 to 400 words. Keep your name at 14 to 16 pt for a clear header. Clean formatting helps a hiring reader focus on your message, which is why cover letter font size and spacing matter more than most job seekers assume.

Key Takeaways

  • Body text: Use 10 to 12 pt, with 12 pt as the safest choice for serif fonts and 10 to 11 pt working well for sans-serif fonts.
  • Header: Set your name at 14 to 16 pt in bold, with contact details at body size.
  • Line spacing: Stick to 1.0 to 1.15. Avoid 1.5 or double spacing, which pads a short letter across pages.
  • Paragraph spacing: Add 6 to 8 pt of space after each paragraph instead of pressing Enter twice.
  • Margins: Use 1 inch on all sides, and go no lower than 0.7 inches if you must fit extra content.
  • Length: Aim for one page and 250 to 400 words across three or four focused paragraphs.
  • Consistency: Match the font family and header style of your CV so the application looks like one set.

Introduction

When job seekers ask about cover letter font size and spacing, they usually want a simple answer: what settings will look professional and fit on one page? The short version is that a cover letter should look easy to read at a glance. Its formatting should fade into the background so the content does the work.

This guide covers the exact numbers to use, why they matter, which fonts to pick, and how to clean up formatting when a draft comes from a chat tool or a template. Whether you are applying for your first remote role or your tenth professional position, the same principles apply.

Typography Basics for Application Documents

Before choosing numbers, it helps to define the terms you will see in every word processor.

Font size (point size): The height of characters measured in points, where 72 points equal one inch. Body text in application documents usually falls between 10 and 12 points.

Line spacing: The vertical space between lines of text, expressed as a multiple of the font’s default height. A value of 1.0 is “single,” and 1.15 adds a small amount of breathing room.

Leading and whitespace: The combined spacing around lines, paragraphs, and margins that determines how dense or open a page feels.

These terms matter because readability depends on the balance between them. Text that is too small or packed too tightly is tiring to scan, while text that is over-spaced looks sparse and unfinished.

What Size Font Should a Cover Letter Be?

The right font size depends on the typeface you choose, since fonts with larger x-heights (the height of lowercase letters) appear bigger at the same point size.

Body Paragraphs: The 10 to 12 pt Standard

For most cover letters, body text should sit between 10 and 12 points. Here is how to choose within that range:

  1. Use 12 pt for serif fonts such as Times New Roman, Garamond, or Cambria. Serifs have smaller x-heights, so they need the larger size to stay legible.
  2. Use 10.5 to 11 pt for sans-serif fonts such as Calibri, Arial, or Helvetica. These fonts have larger x-heights and read clearly at slightly smaller sizes.
  3. Never drop below 10 pt. Text smaller than that strains the eyes, prints poorly, and can make scanning harder for anyone reviewing many applications.

Accessibility guidance from the Nielsen Norman Group, which studies how people read on screens, consistently favors comfortable text sizes and clear visual structure. Smaller text may fit on a page, but it reduces how much of your letter a reader actually absorbs.

Header, Name, and Section Titles

Your header gives the reader a quick anchor, so it should look distinct from the body:

  • Name: 14 to 16 pt, bold. This creates a clear top-level hierarchy.
  • Contact details (phone, email, city, LinkedIn): body size, around 10 to 11 pt.
  • Date and recipient address: body size, placed below the contact block.
  • Section titles, if you use any: body size in bold, or one step up at most. Cover letters rarely need headings, so keep them minimal.

Matching this header structure to your CV creates visual continuity. A reader who sees both documents side by side should recognize them as a set.

Matching Your CV and Cover Letter Typography

Using identical font families and sizes across your application documents signals care and consistency. When the cover letter uses one typeface and the CV uses another, the mismatch can feel disjointed, even if the reader cannot say why.

A simple rule: pick one font family and one set of header sizes, and apply them to both documents. This small step reinforces that the same person prepared everything.

Cover Letter Spacing: Line Height, Margins, and Paragraph Breaks

Spacing determines whether your letter feels organized or crowded. Three settings do most of the work: line spacing, margins, and paragraph breaks.

Line Spacing: 1.0 vs. 1.15 vs. 1.5

Line spacing is one of the most common formatting mistakes. Here is how the main options compare:

Line Spacing Visual Effect Best Use Main Drawback
1.0 (Single) Dense, compact, classic Long-established formats, tight one-page letters Can feel crowded if text is dense
1.15 Slightly open, modern, easy to scan Most cover letters in 2026 Almost none for standard use
1.5 Airy, spacious Drafts for editing or review copies Stretches a short letter across two pages
2.0 (Double) Very loose Manuscripts and academic submissions Looks padded and wastes space for job applications

For most job applications, 1.0 to 1.15 provides the best balance. It keeps the letter compact enough for one page while leaving enough whitespace that dense paragraphs don’t tire the reader. Avoid 1.5 and double spacing; they add length without adding substance.

Instead of pressing Enter twice between paragraphs, set 6 to 8 pt of space after each paragraph in your word processor’s paragraph settings. This gives consistent separation and keeps the layout clean if you edit later.

Page Margins: Maintaining the 1-Inch Border

The standard margin is 1 inch (2.54 cm) on all four sides. This is the default in most word processors and matches the expectations of recruiters and hiring teams who print or annotate documents.

If your letter runs slightly long, you can reduce margins in an emergency, but keep limits in mind:

  • 0.75 to 0.7 inches is the lowest comfortable range when you must fit critical content onto one page.
  • Below 0.5 inches, text risks being clipped during printing or when displayed in some digital viewers.

Shrinking margins is a last resort. Editing for length almost always produces a stronger letter.

Alignment: Left-Aligned vs. Justified Text

Choose left-aligned (ragged right) text for your cover letter. Left alignment keeps the spacing between words even and makes the line beginnings easy for the eye to track from one line to the next.

Justified text can look tidy on the page, but it often creates uneven word gaps, sometimes called “rivers of white,” especially in narrow columns or with long words. These gaps disrupt reading flow and can cause problems for screen readers. Unless a specific template calls for justification, stay with left alignment.

Best Fonts for Cover Letters: Comparison and ATS Compatibility

Font choice affects both human readability and how well your file is parsed by an Applicant Tracking System (ATS), the software many employers use to store and search applications. Standard system fonts are the safest bet on both counts.

Top Font Choices Compared

Font Category Recommended Size Readability Profile Best For
Calibri Sans-serif 10.5 to 11 pt Clean, modern, very screen-friendly Tech, administration, general roles
Arial Sans-serif 10 to 11 pt Neutral, highly legible, universally available Almost any industry
Trebuchet MS Sans-serif 10.5 to 11 pt Friendly, slightly humanist, clear Marketing, customer-facing roles
Georgia Serif 11 to 12 pt Warm, readable on screen, distinctive Writing, education, nonprofit
Cambria Serif 11 to 12 pt Professional, pairs well with Calibri Business, finance, corporate
Garamond Serif 12 pt Elegant, compact, needs larger size Law, publishing, traditional fields

Sans-serif fonts like Calibri, Arial, and Trebuchet MS suit modern, clean applications and read easily on screens.

Serif fonts like Georgia, Garamond, and Cambria suit industries that value tradition, such as finance, law, and publishing. Remember to bump serif fonts up slightly in size, since they generally appear smaller than sans-serif fonts at the same point size.

Fonts to Avoid in Application Documents

Some fonts create real problems, even if they look fun or distinctive:

  • Decorative and display fonts such as Comic Sans, Papyrus, and script typefaces. These fail basic legibility standards and can look unprofessional.
  • Thin or unusual custom web fonts. If the reader’s computer does not have the font installed, the document may fall back to a default that breaks your layout.
  • Courier and other monospace fonts. They take up more horizontal space and look like typewritten drafts.

Standard system fonts protect you from parsing glitches. An ATS reads text more reliably when the font is common, embedded correctly, and not heavily stylized. Stick to fonts that ship with Windows, macOS, and major office suites.

Cover Letter Length and Spacing: Should a Cover Letter Be One Page?

Yes. A cover letter should virtually always fit on one page. Hiring reviewers often scan many applications quickly, and a concise letter shows you can communicate clearly.

The One-Page Rule: Why Word Count Matters

A practical target is 250 to 400 words, usually arranged in three or four short paragraphs. With 1.15 line spacing, standard 1-inch margins, and 11 to 12 pt type, that length typically fills a single page comfortably.

A focused structure might look like this:

  1. An opening paragraph stating the role and your strongest qualification.
  2. One or two body paragraphs connecting specific achievements to the job’s requirements.
  3. A closing paragraph with a clear next step.

Concise writing also demonstrates communication skill, which matters especially for early-career professionals and international graduates who may not yet have a long work history to point to.

How to Fit Your Cover Letter on One Page Without Ruining Formatting

When a draft runs over, resist the urge to shrink the font to an unreadable 8.5 pt. Instead, work through these steps in order:

  1. Trim throat-clearing sentences. Openers like “I am writing to express my interest in the position of…” can usually be cut. Start with your value instead.
  2. Remove repetition. If the job description and your letter both say “strong communication skills,” show the skill with a concrete example and drop the generic phrase.
  3. Combine short paragraphs where the ideas connect naturally.
  4. Adjust line spacing in small steps. Moving from 1.15 to 1.05 is generally safe. Going much lower makes text feel cramped.
  5. Check the margins last. Only reduce them toward 0.7 inches if the earlier steps are not enough.

Editing for length tends to produce a sharper letter, which is almost always better than squeezing the layout.

Formatting Workflows: Google Docs, Word, and AI-Generated Cover Letters

Your tools shape how your formatting holds up, especially when you move a file between platforms.

Formatting in Google Docs vs. Microsoft Word

Google Docs lets you set custom line spacing and paragraph spacing under Format, then Line & paragraph spacing. Setting “Add space after paragraphs” gives consistent separation without manual blank lines. You can save these settings as your default so future letters start with the same layout.

Microsoft Word offers equivalent controls under the Paragraph settings dialog. Be aware that Word documents can carry hidden formatting from earlier edits, such as stray styles, extra spaces, or tab stops, which can shift the layout on another computer.

Why Saving as a PDF Protects Your Formatting

Export your final cover letter as a PDF rather than sending a .docx file. A PDF preserves font geometry, line breaks, and margins exactly as you designed them, regardless of the operating system, software version, or installed fonts on the reader’s device. A .docx file can reflow on a different machine and push your letter onto a second page.

Many application portals accept PDFs, but if one specifically requests a Word file, send .docx and check how it looks by converting it to PDF yourself first.

Cleaning Up Formatting from ChatGPT Cover Letter Drafts

Drafts produced by AI chat tools often need formatting cleanup before they are ready to send. Common issues include:

  • Overly generic salutations such as “Dear Hiring Manager” when you could address a named recruiter.
  • Markdown remnants like pound signs, asterisks, or bullet characters that appear as literal symbols in a Word document.
  • Uniform block paragraphs that lack the breathing room discussed above.
  • Awkward indentation and double line breaks copied from a browser window.

A reliable workflow is to paste the draft into a plain text editor first. This strips hidden formatting. Then reapply your chosen font, size, spacing, and margins in your word processor, and finally export as a PDF.

Tailoring matters as much as formatting. A letter that mirrors specific requirements from a job listing reads as deliberate rather than generic. Believele is an AI job-application coach that analyses a job listing and helps you tailor your CV and cover letter to it, rather than mass-applying.

Template Insights from Job Search Communities

Discussions in career communities such as Reddit’s r/jobs frequently recommend the same principle: simple, single-column layouts outperform complex graphic templates. Many job seekers in these forums report that elaborate designs with columns, icons, and colored bars can break ATS parsing and look out of place in conservative industries.

Reviewers tend to prefer clean margins and legible typography over visual gimmicks. Use community advice as a general signal, not a universal rule, and always check whether a specific employer or portal has its own requirements.

Step-by-Step Cover Letter Formatting Checklist

Use this sequence before you submit any application:

  1. Set the basics. Choose one font family, body size between 10 and 12 pt, and 1.0 to 1.15 line spacing.
  2. Format the header. Name at 14 to 16 pt in bold, contact details and date at body size.
  3. Set paragraph spacing. Add 6 to 8 pt after each paragraph instead of extra blank lines.
  4. Confirm margins. Use 1 inch on all sides unless you must compress to 0.7 inches.
  5. Check length. Keep the letter to one page and 250 to 400 words.
  6. Visual scan. Look for comfortable whitespace around each block of text and consistent alignment.
  7. Technical scan. Export as a PDF and confirm the font matches your CV.
  8. Content scan. Remove all placeholders, check the company and role names, and confirm the letter is tailored to the specific job description.

Frequently Asked Questions

What is the best font size for a cover letter?

The best font size for a cover letter body is between 10 and 12 pt. Use 12 pt for serif fonts like Garamond or Times New Roman, and 10.5 to 11 pt for sans-serif fonts like Calibri or Arial. Set your name in the header at 14 to 16 pt in bold.

Is single spacing acceptable for a cover letter?

Yes. Single spacing (1.0) or 1.15 is the standard for cover letters, as long as you add a clear gap between paragraphs using paragraph spacing of about 6 to 8 pt. Avoid 1.5 or double spacing, which stretches a short letter unnecessarily.

Should a cover letter be one page?

Yes, a cover letter should almost always fit on one page. Aim for 250 to 400 words across three or four focused paragraphs, which fills a single page comfortably with standard margins and 1.15 line spacing.

Can I use 0.5-inch margins if my cover letter is too long?

It is better not to. Margins of 0.5 inches look cluttered and can cause text to be clipped during printing. Edit the letter to cut unnecessary words first, and if you still need more room, the lowest comfortable setting is about 0.7 inches.

What is the best font to use on a cover letter in 2026?

Calibri, Arial, Georgia, and Cambria are strong choices in 2026 because they are installed on most computers and read clearly on screens. Choose a sans-serif like Calibri or Arial for modern roles, or a serif like Georgia or Cambria for traditional industries.

Why does my ChatGPT cover letter look strange when pasted into Word?

Browsers and chat tools often copy hidden formatting, non-standard line breaks, and inconsistent font sizes along with the text. Paste the draft into a plain text editor first to remove this, then reapply your font, size, spacing, and margins in Word before exporting a PDF.
