ATS Resume Formatting: The Mistakes That Get You Filtered Out Instantly

You spent time on your resume. You picked a clean template, organized your experience, and made sure everything fit on one or two pages. It looks professional. It reads well. And it is getting you nowhere.

Here is something most job seekers do not find out until it is too late: a resume that looks great to a human reader can be completely unreadable to an Applicant Tracking System. And if the ATS cannot read it, no human ever will.

ATS resume formatting is not about making your resume look better. It is about ensuring that

the software screening your application can actually extract and process the information it contains. Get this wrong, and it does not matter how qualified you are. The system filters you out before anyone sees your name.

These are the formatting mistakes that cause it, and exactly how to fix them.

Why ATS Formatting Is Different From Regular Resume Formatting

When a person reads your resume, they can interpret context. They can see that a sidebar contains your skills, that a shaded box holds your contact information, and that a two-column layout separates your experience from your credentials. Their brain fills in the gaps.

An ATS does not do that. It reads your document as raw text, extracts data based on structure and labels, and tries to map what it finds to the fields it is looking for. Anything that disrupts that extraction process causes parsing errors. And parsing errors mean your content either gets scrambled, gets dropped, or gets misattributed to the wrong section entirely.

The result is that a beautifully designed resume can produce a parsed output that looks like nonsense, and the recruiter never knows you had exactly what they were looking for.

Mistake 1: Two-Column Layouts

This is the most common ATS formatting mistake, and it is everywhere right now. Two-column resume templates are popular, widely recommended, and actively sold by resume writers and template marketplaces. They look polished and modern to a human reader.

They are also one of the fastest ways to get your resume rejected before anyone reads it.

Most ATS systems read documents the same way a scanner would: left to right, line by line, across the full width of the page. When your resume is divided into two columns, the system reads across both columns simultaneously, pulling content from column one and column two in the same line. Your skills section gets merged with your work history. Your contact information gets tangled with your job titles. The output is scrambled and unreadable.

The fix: Use a single-column layout. All of your content runs down the left side of the page in a clean, linear structure. It may look less visually dynamic, but it parses correctly every time.

Mistake 2: Tables

Tables have the same problem as columns, just in a different form. Content inside a table cell is often dropped entirely during ATS parsing, or pulled out of sequence in a way that makes it meaningless.

This matters most for skills sections, which are frequently formatted as tables or grids. If your skills are sitting inside a table and the ATS cannot extract them, you are missing keyword matches that could have pushed your score over the threshold.

The fix: List your skills as plain text, separated by commas or line breaks, in a standard Skills section with no table formatting.

Mistake 3: Contact Information in Headers or Footers

Your name, phone number, and email address are the most important pieces of information on your resume. If a recruiter wants to reach you after your resume passes screening, that information needs to be accessible.

Here is the problem: Microsoft Word and Google Docs both have a dedicated Header area at the top of the document. It seems like the natural place to put your name and contact information. Many resume templates put it there by default.

Most ATS systems cannot read content stored in a document header or footer.

They parse the document body and skip everything else. Which means your name and contact details may be completely invisible to the system screening your application.

The fix: Put your contact information in the body of the document, not in a Word or Google Docs header. Your name, phone number, email, LinkedIn URL, and location should all appear as regular text at the top of page one.

Mistake 4: Graphics, Icons, and Images

Visual elements have become increasingly common on resumes, particularly for candidates in creative fields. Skill bars that show proficiency levels. Icons next to contact information. Logos for past employers. Profile photos.

None of these parse correctly in an ATS. Images and graphics are skipped entirely. Any information conveyed visually, including text inside an image, is invisible to the system. Skill bars that show your proficiency level as a visual meter communicate nothing to the ATS. A text label does.

The fix: Remove all graphics, icons, images, and visual elements. Replace anything that conveys information visually with plain text. If a skill bar showed you as proficient in a tool, write the tool name in your skills section as text.

Mistake 5: Text Boxes

Text boxes are a common design element in resume templates, used to call out key information, create visual separation, or highlight credentials. They look intentional and clean in the finished document.

ATS systems treat text boxes the same way they treat images: the content inside them is frequently skipped or extracted incorrectly. Whatever you put in a text box may not exist from the system's perspective.

The fix: Take any content out of text boxes and put it directly into the body of the document as regular text. If the information was worth highlighting in a box, it is worth including as plain text where the system can actually find it.

Mistake 6: Unusual Fonts

Font choice affects ATS parsing more than most people realize. Decorative, script, or highly stylized fonts can cause character recognition errors during parsing, resulting in garbled content even if the document structure is otherwise clean.

Beyond parsing, unusual fonts can cause rendering issues when your resume is viewed across different environments. What looks intentional on your screen may look broken on a recruiter's display.

The fix: Use standard, widely supported fonts. Arial, Calibri, Garamond, and Times New Roman all parse cleanly and render consistently. Keep your body text font size between 10 and 12 points, and use slightly larger sizes for your name and section headers.

Mistake 7: Creative Section Labels

This one surprises people because it feels like a small detail. But ATS systems identify sections of your resume by their labels. Work Experience, Education, Skills, Certifications — these are the terms the system is trained to recognize.

When you label a section "My Career Journey," "What I Bring to the Table," or "Core Competencies" instead of "Skills," the system may not correctly identify what that section contains. Content that should contribute to your keyword match score in a particular category may get misclassified or missed entirely.

The fix: Use conventional, straightforward section labels. Work Experience. Education. Skills. Certifications. Summary. These labels are boring by design, and they work every time.

Mistake 8: Saving in the Wrong File Format

Most ATS systems handle both PDF and Word documents, but not all handle them equally well. Some systems parse Word documents more reliably. Others handle PDFs without issue. A small number struggle with PDFs created from scanned images rather than digital text.

The safest approach is to check the job posting. Some employers specify a preferred format. If no format is specified, a Word document (.docx) is the most universally compatible option.

Never submit a resume as an image file, a Pages document, or a scanned PDF. These formats consistently cause parsing failures.

How to Know If Your Resume Has Formatting Problems

The simplest test is to copy all the text from your resume and paste it into a plain-text editor like Notepad. What you see is roughly what an ATS will extract from your document.

If the text is scrambled, columns are running together, or content is missing or out of order, your resume has a formatting problem that will affect how it parses during ATS screening.

Go through the mistakes listed above and address each one. Then run the plain text test again. When the pasted content reads cleanly and in the right order, your formatting is ATS-ready.

Formatting Is the Foundation

Keywords get a lot of attention in conversations about ATS optimization, and they

matter. But keywords only help if the system can find them. If your resume has formatting problems that prevent clean parsing, your keyword strategy is irrelevant.

Fix the formatting first. Then optimize your language in that order.

If you want the full picture, the ATS Resume Guide covers both: the formatting rules that ensure your resume parses correctly and the six-step keyword optimization process that gets your content matching the roles you are targeting.
