When you’re applying for college internships, your resume doesn’t just need to impress a human recruiter it first has to get past an applicant tracking system (ATS). These automated tools scan resumes before anyone even sees them. If your font isn’t readable by the software, your application might be rejected before a person reads a single word. That’s why picking fonts that work well with ATS matters more than most students realize.

What does “ATS-friendly font” actually mean?

An ATS-friendly font is one that applicant tracking systems can easily read and parse without errors. These systems convert your resume into plain text to extract information like your name, school, skills, and job titles. Fancy script fonts, ultra-thin weights, or decorative typefaces often break this process. Stick to simple, clean, widely available fonts that render consistently across different operating systems and software.

Which fonts should you actually use?

Here are some reliable choices that won’t trip up the ATS:

  • Arial – Clean, neutral, and universally supported.
  • Calibri – Default in newer Microsoft Word versions, easy on the eyes.
  • Helvetica – Professional and widely used, though not always pre-installed on all machines.
  • Georgia – A serif option that still scans cleanly if you prefer that style.
  • Times New Roman – Old-school but safe; avoid if you want a more modern look.

What about serif vs. sans-serif for internships?

Both can work as long as they’re standard system fonts. Sans-serif fonts like Arial or Calibri tend to feel more modern and are slightly easier to read on screens which is where most recruiters will view your resume. Serif fonts like Georgia or Times New Roman can add a traditional, academic tone. You can compare both styles in our breakdown of font choices for entry-level applicants.

Common mistakes that break ATS parsing

Students often make these font-related errors without realizing the consequences:

  • Using downloaded or custom fonts (like Poppins, Lato, or Garamond) that aren’t embedded properly.
  • Formatting headers or section titles in all caps or extra-bold weights that confuse the parser.
  • Inserting text inside images, tables, or text boxes ATS can’t read those at all.
  • Using font sizes under 10pt or over 14pt for body text, which can cause readability issues.

How to test if your resume font is ATS-safe

Before submitting, copy and paste your entire resume into Notepad or TextEdit. If the formatting collapses but all your content is still there and readable, you’re probably okay. If chunks of text disappear or turn into gibberish, your font or layout is causing problems. Another option: upload your resume to free ATS simulators online they’ll flag parsing errors.

Should you change fonts for grad applications later?

Not necessarily. The same principles apply whether you’re applying for an internship or your first full-time job after graduation. What changes is how much experience you have to showcase not the technical setup of your document.
