ATS Resume Formatting Rules: Fonts, Layout, and File Type

You find a job you want, upload your resume, and expect the application to take just a few minutes. But then you have to type in your work history again because the form has missed half the details. If you've been there, you know how frustrating it is, especially when it's your fifth or tenth application that day and the same thing keeps happening over and over again.

That's where ATS resume formatting can help. You may only need to change a few things in your layout to make your details easier for the software to read. It's worth checking, especially if you're applying to large employers.

If your resume looks fine in your document but things get mixed up when you upload it, these formatting tips can help you work out what's going wrong and save you time and nerves on your next application.

What Makes a Resume Format ATS-Friendly?

An ATS-friendly resume format makes it easier for hiring software to read your details and put them in the right place. When you upload your resume, the system tries to pick out your name, contact information, work history, and education. This is called resume parsing, and your layout can affect how accurately it works.

For example, when a recruiter reads your work history, they can usually tell which job title, company, and dates belong together. The software needs to make sense of those details too, so it helps to keep everything about each role together. So, put each job in its own block, with the title, employer, and dates followed by bullet points explaining what you did. You don't need separate boxes or a complicated layout to make the entry look organized.

Here's a simple example:

Customer Success Specialist — Brightline Software | March 2023 to Present

• Managed onboarding for 35 business customers, coordinating training and account setup.
• Created help materials that reduced repeated setup questions during onboarding.

Everything about the role is in one place, making it easier to follow both on the page and when the text is extracted. Use the same pattern for the rest of your work history. If you start with the job title, do that for every role, and keep your dates consistent rather than switching between "March 2023" and "03/2023."

Keep in mind you also want the resume to be comfortable for a person to read. So, leave some space between sections, keep your text left-aligned, and break your achievements into bullet points so they don't get lost in a long paragraph. Once the layout is clear, focus on what you're saying. While an ATS-friendly format helps make your experience readable, it's the relevant skills, work, and results you describe that give an employer a reason to invite you for an interview.

Which Sections and Headings Does an ATS Recognize?

When someone opens your resume, they should be able to find your work history, education, and skills without having to guess where you've put them. Familiar headings help with that and make the structure clearer for the software reading your file, too. You don't need to follow one exact list of headings, but names such as "Work Experience," "Education," and "Skills" are good choices because they tell the reader what to expect.

For example, "Work Experience" is easier to understand than "My Journey." You can still make your resume feel like you through the work and examples you describe, so there's no need to get creative with the section names.

Keep your name and contact details at the top of the page, within the main document text. If you're using Word, that means typing them above your summary rather than putting them inside the Insert Header area. The order of the sections should reflect what's most relevant to the job. If you already have experience in the field, put your work history near the top. If you're applying for your first job, your education and projects may tell the employer more about what you can do.

Use a clear Skills heading, then support relevant skills with examples in your work or project entries. In NACE's Job Outlook 2025 survey, nearly 90% of responding employers looked for evidence of problem-solving skills on college students' resumes, while nearly 80% looked for teamwork. The survey included 237 employers recruiting college graduates.

ATS-Friendly Fonts and Font Sizes

It's easy to spend more time than you planned choosing a font, especially when you're trying to make everything fit on the page. But you don't need to keep switching between Arial and Calibri to work out which one an ATS will prefer. Choose a familiar font that's easy to read, then check how it looks across your resume.

Arial, Calibri, Aptos, Times New Roman, and Georgia are all common, readable choices for an ATS-friendly resume. Whether you prefer the look of Arial or something more traditional like Times New Roman, keep your text clear and consistent. The truth is, there's no single font that gives your resume an advantage in every ATS. What matters is that your wording stays readable and your layout holds up when you save or export the file.

Harvard's Mignone Center for Career Success recommends common fonts and a consistent size between 10 and 12 points in its resume guidance for PhD students. For most resumes, 11 or 12 points is a good starting point for the main text. You can use these sizes as a guide. They're suggestions to keep your resume readable, not requirements set by an ATS:

You don't need to stick to these sizes exactly, as some fonts look bigger than others even at the same size. Simply take a look at the finished page and check that you can read everything comfortably without zooming in.

Bold headings, job titles, or company names can make your resume easier to scan. You can keep the same font throughout and use bold text or a slightly larger size to help each section stand out. Also, skip decorative script and very thin fonts if they make you work harder to read the words. And if you're tempted to space out the letters in your name or headings to make them look more stylish, keep them together so the software has a better chance of reading them correctly.

If everything won't fit on the page, see what you can trim before making the font smaller. You may be repeating the same duties in a few places, or your summary might be longer than it needs to be. If the information is relevant and the employer hasn't specified a page limit, a readable second page is better than squeezing everything into tiny text. One more tip: start with margins around 0.75 to 1 inch and leave enough space between sections so each one is easy to find.

Can an ATS Read Two Columns, Tables, and Graphics?

If you've picked a two-column template, you can see why it works visually. Your skills and contact details sit neatly on one side, leaving more room for your work history on the other. But when hiring software reads the file, those details may not stay in the order you intended. Some systems can handle more complicated layouts, while others may mix up or miss information. Greenhouse's parsing documentation lists columns, complex tables, graphics, and contact details inside headers, footers, or text boxes as possible causes of parsing problems. So, if you don't know which system the employer uses or how it will read your file, a single-column resume is a safer starting point.

You may not need to change much to simplify your current template. If your sidebar only contains a few skills, move them under a Skills heading in the main text. If you've used a table just to line up dates, try putting the dates alongside the job details instead. Here are a few other changes you can make:

• Move information from the sidebar into the main resume sections.
• Write out your skills instead of showing them with stars or rating bars.
• Include your email address and phone number as text rather than relying on icons.
• Explain project results in bullet points instead of putting important details in a chart.

Skill ratings can also leave employers guessing, even if the software reads them correctly. "Excel: four stars" doesn't say if you can build a pivot table, clean a dataset, or create a reporting dashboard. Naming the tasks you can do gives them a clearer idea of your experience. If you're applying for a creative role and want to show your design work, include a visible link to your portfolio. That lets the hiring team see your work while keeping your resume focused on your experience and achievements.

Before rebuilding a two-column resume, check whether the text in your exported file comes out in the right order. The walkthrough in the checking section below can help you spot details that have become mixed up. A sensible reading order is a good sign, although it doesn't guarantee every ATS will read the file the same way.

Should an ATS Resume Be a PDF or Word Document?

PDF or Word? You'll find plenty of advice recommending one over the other, but the employer's instructions are the best place to start. If the application asks for a DOCX file, send that, and if it asks for a PDF, use your PDF version. When both are accepted, either can work. Greenhouse's supported-file guidance includes both PDF and DOCX, so you don't need to switch to Word just because you've heard that an ATS can't read PDFs.

The thing to watch is how you've made the PDF. If you save it directly from Word or Google Docs, the text will usually stay selectable and the layout should stay in place. But if you take a screenshot of your resume or scan a printed copy, you're creating a picture of the page. The software may then need to recognize the words in that image before it can read them. You can check this by opening your PDF and trying to select a sentence. If you can't select anything, go back to your original document and save a new PDF from there.

If the application form fills in your details incorrectly, correct the fields before submitting. You can also try the other file format if the employer accepts it. Keep an editable copy so you can update your resume without trying to make changes inside the PDF. After each update, open the file you're about to send and check that nothing has shifted onto another page or left a heading sitting on its own.

It also helps to give the file a clear name, such as "Maya_Patel_Customer_Success_Resume.pdf." When you've got several versions saved for different jobs, that makes it easier to find the right one than a folder full of files called "resume_final." Before uploading, check the file-size limit on the application page. If your file is much larger than you expected, look for images or other extras you can remove. Then check that you've attached the right version for the job, especially if this is one of several applications you're working through that day.

How to Check Whether Your Resume Is ATS-Friendly

Once you've sorted out the layout and saved your file, it's worth checking what happens to the text before you send it. A resume can look good in Word or as a PDF and still have details that get missed or read in the wrong order.

Here's what to do. Start by opening the file you're going to upload, copying the text, and pasting it into a basic text editor such as Notepad. Read through it and check that your contact details, job titles, dates, and education are all there and appear where you'd expect them. Don't worry if the bold text and spacing disappear, as that's normal when you paste into plain text. What you're looking for is missing information, words that have broken apart, or sections that have become mixed together. If you spot a problem, go back to your original document, simplify that part of the layout, and save a new version.

For another check, upload your file to AIApply's AI Resume Checker. It accepts PDF, DOC, and DOCX files and gives you feedback on your content, structure, formatting, keywords, and common writing errors. That can make it easier to see what needs attention rather than wondering whether you should rewrite the whole resume. Read through the suggestions and decide which ones apply. Clearer headings or consistent job entries may be straightforward fixes, but only add a suggested skill or achievement if it reflects something you've actually done.

You also don't need to keep editing just to chase a higher score. A resume checker gives you feedback based on its own criteria, and employers may assess your application differently. Use the results to guide your changes, then check that the resume still reads naturally and describes your experience accurately.

Once the formatting looks right, compare the wording with the job description. Make sure the relevant tools, qualifications, and experience you have are easy to find rather than expecting the recruiter to work them out from vague descriptions.

When you upload your resume to an application, take a moment to review any details the form fills in for you. Correct anything it has missed or put in the wrong place before submitting, even if your attached resume looks fine. Finally, open the attachment itself and check your contact details and page breaks, especially if you've made changes since your last application. To get started, check your resume with AIApply, work through the suggestions that help, and save the version you're ready to send.
