Why Font Choice Matters for ATS Systems

When you submit a resume to a company that uses an Applicant Tracking System, the software must first convert your document into parseable text before it can scan for keywords, extract your work history, and score your application. This conversion step is where font problems occur.

Decorative fonts, script fonts, and non-standard typefaces frequently cause parsing errors that result in garbled or missing text inside the ATS database. Your job title might be extracted as random characters. Your contact information might disappear entirely. Your carefully crafted bullet points might be skipped.

The result: a 0% ATS match score for a candidate who is actually highly qualified — simply because their font choice broke the parser. To prevent this, every font you use on a resume must meet three criteria:

  • Available as a system-standard font (not downloaded, not custom)
  • Rendered as selectable text (not embedded as an image or graphic)
  • Simple enough that every ATS version can read it without errors

Top Sans-Serif Fonts for a Resume

Sans-serif fonts (those without decorative strokes at the ends of letters) are the dominant choice for modern resumes. They read cleanly on screen, scale well across font sizes, and are universally supported by ATS software.

1. Calibri — The Gold Standard

Calibri has been the default Microsoft Word font since 2007 and is the most widely used resume font in the world. It is warm, modern, and highly readable at all sizes. Every ATS system on the market parses Calibri flawlessly. It is our top recommendation for the majority of job seekers across all industries.

Best for: All industries; particularly tech, finance, healthcare, and corporate environments.

2. Arial — The Reliable Classic

Arial is available on virtually every operating system and has been a design staple for decades. It is clean, professional, and zero-risk from an ATS perspective. Some candidates find it slightly plain, but that simplicity is exactly what makes it dependable.

Best for: Corporate, legal, finance, and any role where conservatism signals credibility.

3. Helvetica — The Designer's Choice

Helvetica is the preferred font for graphic designers, marketing professionals, and creatives who want a polished, minimalist aesthetic without sacrificing ATS compatibility. It is a Mac system font and available as a download on Windows.

Best for: Design, marketing, advertising, tech, and startup environments.

4. Trebuchet MS — The Modern Alternative

Trebuchet MS offers slightly more character than Arial while maintaining full ATS compatibility and system-wide availability. A good choice if you want to stand out subtly from the sea of Calibri resumes.

Best for: Education, nonprofits, communications, and creative fields.

Top Serif Fonts for a Resume

Serif fonts (those with small decorative strokes at the ends of letters) convey tradition, authority, and formality. They are the preferred choice in law, academia, finance, and executive roles. All of the following are fully ATS-safe.

1. Garamond — The Executive Choice

Garamond is elegant, distinguished, and associated with high-level print and publishing standards. It reads beautifully on paper (and in PDF), making it the ideal choice for printed executive resumes and academic CVs. Its slightly smaller footprint at the same point size allows you to fit more content without crowding.

Best for: Legal, academic, executive, consulting, and finance roles.

2. Georgia — The Digital Serif

Georgia was designed specifically for screen legibility — an important distinction when most resumes are first reviewed on a monitor. It is a system-standard font on both Mac and Windows and parses perfectly in all ATS environments.

Best for: Law, government, academia, publishing, and traditional industries.

3. Times New Roman — Use With Caution

Times New Roman is the most recognized serif font in the world — which is also its greatest disadvantage. It is so widely associated with default word processing documents that using it on a resume can signal to hiring managers that no design thought was applied. It is ATS-safe, but you should upgrade to Garamond or Georgia unless you are applying to roles with strict document formatting requirements (e.g., government, federal, legal).

Best for: Federal government applications, legal documents, academic submissions.

Exact Font Size Rules for a Resume

Font size affects both readability and ATS parsing. Sizes that are too small can be skipped by parsers, while sizes that are too large look amateurish. Follow these rules:

  • Your name (header): 18–24pt. This is the only element that should be dramatically larger than the rest.
  • Section headers (Work Experience, Education, Skills): 12–14pt, bold.
  • Job titles: 11–12pt, bold or semi-bold.
  • Body text (bullet points, descriptions): 10–12pt. Never go below 10pt — some ATS systems have a minimum threshold below which text is skipped.
  • Contact information: 10–11pt.
  • Dates and locations: 10pt is acceptable.
📏 The 10.5pt Rule

If your resume runs slightly over one page, reduce body text from 11pt to 10.5pt before reducing margins or removing content. This small change often eliminates the overflow while keeping text comfortably readable.

Fonts You Must Never Use on a Resume

These fonts either cause ATS parsing failures, signal unprofessionalism to hiring managers, or both. Remove them from your resume immediately if you are using any of them:

  • Comic Sans — Universally associated with casual and unprofessional contexts. Never appropriate for a professional resume.
  • Papyrus — A decorative novelty font that ATS systems frequently misparse and hiring managers find jarring.
  • Courier / Courier New — Monospace typewriter font. Fine for coding portfolios, inappropriate for resumes unless in a specific technical code block.
  • Any script or handwriting font — Brush Script, Zapfino, Lobster, etc. These are almost guaranteed to cause ATS parsing errors and appear extremely unprofessional in business contexts.
  • Custom downloaded fonts — If a font is not built into the operating system, it may not embed correctly in PDF export, causing the reader's system to substitute a different font entirely — which can destroy your formatting.
  • Fonts with ligatures or advanced OpenType features — These typographic refinements look beautiful in print but frequently confuse ATS parsers.

Should You Use One Font or Two?

One font is always the safer choice. Two fonts can look sophisticated if executed well, but add complexity. If you do use two fonts:

  • Use one for headings and one for body — never more than two
  • Pair a sans-serif with a serif (e.g., Calibri for body, Garamond for section headers)
  • Both fonts must individually meet the ATS-safe criteria above
  • Test the combination by exporting to PDF and checking that both fonts are embedded correctly
✅ Quick Decision Guide

For most job seekers: Calibri 11pt throughout, with section headers bolded at 12pt. This is the universal safe choice.
For senior/executive roles: Garamond 11pt body, 13pt section headers.
For creative/design roles: Helvetica 11pt throughout with strategic spacing.
