An ATS-friendly resume is one that a resume parser can read in the right order and a recruiter can skim: a single column of real text, standard section headings, your contact details in the body of the page, a common font, and a .docx or text-based PDF file. Most other “ATS rules” are habit or myth.

Formatting does not get you hired or rejected by itself. A resume that parses badly arrives with empty or scrambled fields and is harder to find in a search, which is reason enough to keep the layout plain.

## Key takeaways

- Use one column that reads top to bottom. Tables, text boxes and columned layouts are documented causes of failed parsing.
- Keep your name and contact details in the body of the page, not in the header or footer.
- Use standard headings, full job titles and the same entry format throughout.
- Send the file type the form asks for. Otherwise a .docx or a PDF exported from your word processor both work. A scan or photo does not.
- A failed parse is not a rejection. It means the fields were not filled in automatically.
- Test before you apply by saving the resume as plain text and reading what is left.

## What an ATS does with your resume file

An applicant tracking system stores your file and typically parses it. Greenhouse describes parsing as scanning an imported resume and auto-filling fields with the information it detects. The text also becomes searchable, which is why wording matters as much as layout; see the guide to [resume keywords](https://jobbie.bot/blog/resume-keywords).

A parser is a text extractor that guesses. It pulls the text out of the file, then works out which words are your name, an employer, a job title or a date from their position and the labels around them. Three things make the guess worse:

- text it cannot extract, because it is inside an image
- text out of order, because of columns, tables or text boxes
- text without familiar labels, because the headings or titles are unusual

Your resume has two readers, the parser and a person. Every rule below serves both. For the wider picture, including screening questions and scoring, read [what an ATS is](https://jobbie.bot/blog/what-is-an-ats).

## ATS resume formatting rules, element by element

| Element | Do | Avoid | Why |
| --- | --- | --- | --- |
| File type | The format the form requests; otherwise .docx or a text-based PDF | Scans, photos and screenshots of a resume | Greenhouse lists resumes uploaded as an image, instead of a document such as .docx or .pdf, as a cause of failed parsing |
| File size | A small, text-only file | Heavy files with embedded images | Greenhouse cannot parse resumes larger than 2.5MB; Workable’s application forms cap resume uploads at 5MB |
| Layout | One column, left-aligned | Columns, tables, text boxes | Greenhouse lists columned layouts and tables; MIT’s career office warns that columns and text boxes can put text in the wrong order |
| Contact details | The first lines of the page body | The page header or footer, or a text box | Greenhouse names this placement as a parsing problem |
| Headings | Experience, Education, Skills, Projects, Certifications | Creative headings such as “My journey so far” | Unusual headings make sorting hard, and Greenhouse flags resumes without clear sections |
| Job entries | Full title, employer, location and dates, in the same order every time | Shortened titles such as “Sr. Acct. Exec.” and formats that change between entries | Greenhouse lists incomplete job titles and inconsistent section formatting |
| Fonts | Arial, Calibri, Cambria, Georgia, Helvetica or Times New Roman, at 10 point or larger | Downloaded or decorative fonts; letters spaced out for effect | MIT’s career office recommends common fonts; Greenhouse lists spaces between letters |
| Graphics | None | Photos, icons, logos, charts, skill bars, word art | Greenhouse lists graphics, photos and word art; software cannot pull information from an image |

Two more details from university career centers: write web addresses out in full, because a system may display only the URL and drop the word you linked, and keep bullets round or square.

Note the company name. Greenhouse’s list also includes company names without identifying words such as Inc., Co. or LLC, so write each employer’s name in full.

## PDF or Word: which file type to use

Follow the application form. If it names a format, use that one.

If it does not, the sources disagree, which tells you neither format is a problem in itself. The University of Minnesota Duluth’s career center says ATS prefers .docx unless the ad asks for a PDF. Greenhouse tells candidates using its MyGreenhouse profile to upload a PDF for best results. MIT’s career office calls .doc, .docx and .pdf all fairly safe unless the job description says otherwise. Workable’s forms accept .pdf, .doc, .docx, .rtf, .html and .odt.

What matters is whether the file contains real text:

- **Export, do not scan.** Use “Save as PDF” or “Download as PDF” from your word processor. A printed resume that was scanned or photographed is a picture of text.
- **Run the cursor test.** Open the file and drag across a sentence. If you cannot highlight individual words, a parser cannot read them either.
- **Be careful with design tools.** MIT warns that design apps, LaTeX and online resume builders can add formatting that confuses an ATS. If you use one, test the output. The guide to [resume templates](https://jobbie.bot/blog/resume-templates) covers what to look for.

## ATS myths you can ignore

| Myth | What the documentation shows |
| --- | --- |
| “An ATS automatically rejects a badly formatted resume” | When a parse fails in Greenhouse, the recruiter sees that the resume has only been attached to the candidate and must enter the details by hand. Bad formatting costs you accuracy and visibility. It is not a rejection rule. |
| “ATS cannot read PDFs” | Greenhouse names .pdf as a document format and recommends PDF to its own candidate users. Workable accepts PDF resumes. Image-only PDFs are the real problem. |
| “Never use bold, italics or bullets” | The University of Minnesota Duluth’s career center recommends bold and italics for emphasis, underlining for headings, and round or square bullets. |
| “You need a special ATS font” | No source here names a required font. MIT lists six common ones and warns only against small, colorful or stylized type. |
| “Hidden keywords beat the system” | Hidden text is still text, and it shows up in any plain-text view. One career center’s summary: ATS tricks are cheating, and employers will question your ethics. |
| “One format works everywhere” | Systems differ, down to their file size limits. Follow each form’s instructions. |

The automatic rejections that vendors do document are rules tied to answers on screening questions, not to fonts or margins.

## How to test your resume before you apply

1. **Run the cursor test** described above to confirm the file holds real text.
2. **Save a copy as plain text.** MIT suggests saving your resume as a .txt file, which strips the formatting and leaves only the text, so you can see whether anything is distorted or missing.
3. **Read it from the top.** Your name and contact details should come first, then each section in order, with every job’s title, employer and dates together.
4. **Fix what broke.** Text in the wrong order usually points to columns or text boxes. Missing contact details point to a header or footer.
5. **Check the form after you upload.** When an application fills its fields from your resume, review every one. Greenhouse tells candidates to review and edit their information before submitting.

If the test fails, fix the layout, not the content. The guide to [resume format](https://jobbie.bot/blog/resume-format) has clean structures to copy. Once the layout is safe, the real gains come from [tailoring your resume to the job description](https://jobbie.bot/blog/tailor-resume-to-job-description).

## Frequently asked questions

### Is PDF or Word better for an ATS?

Use whichever the application form asks for. If it does not say, a .docx or a PDF exported from your word processor will both work. The file that fails is a scan or photo of a resume, because it contains a picture instead of text.

### Can an ATS read a two-column resume?

Not reliably. Greenhouse lists columned layouts among the common causes of failed parsing, and one university career center warns that an ATS reads left to right across the page even when there are columns, which mixes sections together. A single column removes the risk.

### Will an ATS reject my resume because of its formatting?

The vendor documentation cited here does not describe that. In Greenhouse, a resume that fails to parse stays attached to the candidate’s record and the details are entered by hand. The practical harm is that your fields may be empty or wrong and your resume harder to find in a search.

### What is the best font for an ATS-friendly resume?

Any common one. MIT’s career office suggests Arial, Calibri, Cambria, Georgia, Helvetica or Times New Roman at 10 point or larger. Avoid fonts you downloaded, decorative type, and spacing letters apart for effect, which Greenhouse lists as a parsing problem.

### Can I use color, bold or italics on an ATS resume?

Yes. Bold and italics are ordinary text formatting, and the University of Minnesota Duluth’s career center recommends them for emphasis. It also notes that an ATS sees all colors as the same text, so one or two colors do no harm. Keep the page readable in black and white.

### Should my contact information go in the header?

Put it at the top of the page, but in the body, not in the word processor’s header area. Greenhouse lists a name and contact details placed in the header, footer or a text box as a cause of failed parsing.
