Resume Format & ATS
Why Single-Column Resumes Work Better in ATS Systems
by LinkTextFix — May 5, 2026
Your resume looks great. The two-column layout is clean, professional, and visually balanced. The problem is that the ATS system you are submitting to cannot read it — and it is silently scrambling your work history, skills, and job titles without telling you.
How ATS Systems Read Your Resume
Applicant tracking systems do not see your resume the way a human does. They extract the raw text and process it as a linear stream — left to right, top to bottom — one character at a time. There is no visual awareness of columns, headers, or layout. The system reads text in the order it appears in the document's underlying data, not the order it appears on screen.
For a single-column resume, the reading order and the visual order are the same. Your name appears first, then your contact information, then your summary, then your work history, then your education, and so on. The ATS receives a clean, logical sequence it can parse into a structured record.
What Happens To a Two-Column Resume
A two-column layout breaks this assumption. When an ATS — or a PDF extractor — reads a two-column page, it processes text objects sorted by their vertical position. Both columns share the same vertical space, so their text gets interleaved line by line as the parser moves down the page.
Example — What the ATS actually receives
What you see (Left Column)
Senior Developer
Acme Corp
2020 – Present
• Led team of 6 engineers
• Reduced deployment time by 40%
What you see (Right Column)
Skills
Python, JavaScript, SQL
AWS, Docker, Git
Education
B.S. Computer Science
What the ATS reads
Senior Developer Skills
Acme Corp Python, JavaScript, SQL
2020 – Present AWS, Docker, Git
• Led team of 6 engineers
Education
• Reduced deployment time by 40% B.S. Computer Science
The job title and skills get merged. The company name appears next to a skills list. Education gets embedded inside a bullet point. This is what the recruiter's system has on file for you — even though your resume looked perfect when you submitted it. Keyword matching fails because "Python" is now attached to "Acme Corp" and the parser cannot isolate it as a skill.
Why PDF Two-Column Layouts Are Even Worse
Word documents with two columns at least have some structural metadata. PDFs do not. A PDF stores every text element as an independent object positioned at exact X and Y coordinates on the page. When extracting text, the software sorts these objects — usually by Y position (vertical) first, then X position (horizontal) within the same line.
In a two-column PDF, the left and right columns share overlapping Y ranges across the full height of the page. Every extraction pass pulls a line from column A, then a line from column B, then back to column A — because they sit at the same Y coordinate. The resulting text is completely interleaved, and there is no way to un-mix it without knowing the original column boundaries, which the PDF does not store.
Designed Templates: Additional Problems
Beyond column interleaving, design-heavy resume templates introduce several additional failure modes in ATS systems:
Skill bars and progress indicators
Visual bars showing skill proficiency (like "Python ████████░░ 80%") are rendered as graphics. The ATS strips the graphic and may read nothing, or may read the raw Unicode block characters as garbage. Your top skill becomes invisible to keyword matching.
Icons and profile photos
Icons for phone, email, location, and LinkedIn are images. The ATS strips them, sometimes leaving blank fields or stripping the contact information that was positioned next to them. Your phone number may simply not appear in the parsed record.
Decorative and custom fonts
Designer resume templates use fonts that encode characters in non-standard ways. What looks like the letter "f" on screen may be stored as a different Unicode codepoint. When extracted, it becomes a garbled character or question mark. This is the root cause of garbled PDF text.
Colored section headers
Section labels in colored boxes or with background fills are sometimes implemented as text-over-image. The ATS strips the image layer and may lose the section label entirely, leaving the content of that section with no category attached.
Which ATS Systems Are Most Affected
Every major ATS struggles with multi-column and designed resumes, but some are more punishing than others:
How To Check If Your Resume Has a Column Problem
The fastest way to test your resume before submitting is the plain text paste test:
- 1Open your resume in Word or as a PDF and select all text (Ctrl+A or Cmd+A)
- 2Copy it and paste into a plain text editor — Windows Notepad, Mac TextEdit in plain text mode, or directly into LinkTextFix
- 3Read the result from top to bottom. Does the text flow in the same logical order as your visual resume? Or do you see skills appearing next to job titles, dates separated from companies, or sections scrambled together?
- 4If the order is wrong, your resume has a column layout problem that will affect every ATS submission
What To Do About It
If you are in a job search right now and do not have time to rebuild your resume template, here is the fastest path to clean submissions:
- •Copy your resume text and paste it into LinkTextFix to fix encoding errors, broken bullets, and garbled characters from the PDF extraction
- •Review the cleaned output — manually reorder any sections where column interleaving has scrambled the content
- •Paste the corrected, cleaned text into the ATS text field directly instead of uploading the designed PDF
The longer-term fix is to maintain two versions of your resume: a visually designed PDF for human readers and email, and a clean single-column Word or plain text version specifically for ATS submission. Many professional resume writers recommend this two-version approach for exactly this reason.

Open LinkTextFix — FreeFrequently Asked Questions
Why do ATS systems prefer single-column resumes?
ATS systems extract and parse text linearly — left to right, top to bottom. A single-column resume produces a clean, ordered text stream. A two-column resume causes the parser to interleave text from both columns, scrambling job titles, dates, skills, and bullet points into a sequence the ATS cannot interpret correctly.
What happens to a two-column resume inside an ATS?
The text from both columns gets merged line by line as the parser reads down the page. Job titles appear next to skills. Company names appear next to education. Dates get separated from the positions they belong to. Keyword matching fails because terms appear in the wrong context.
Do designed resume templates hurt ATS parsing?
Yes. Skill bars become unreadable as text, icons strip out contact information, decorative fonts cause encoding errors, and colored section headers may lose their labels. The visual design that impresses a human reader becomes noise that breaks machine parsing.
Which ATS systems are most affected?
Oracle Taleo is the most aggressive — it strips nearly all non-standard formatting and fails silently. Workday and iCIMS are highly sensitive to tab characters from two-column Word layouts. LinkedIn strips all formatting. Greenhouse and Lever are more forgiving but still affected by PDF column interleaving.
How can I tell if my resume has a two-column layout problem?
Copy all text from your resume and paste into a plain text editor. If skills appear in the middle of your work history, if dates are separated from job titles, or if sections are scrambled — your layout will cause the same problem in every ATS you submit to.
What should I do if my resume is two-column?
Keep your designed PDF for sending to human contacts. For ATS submissions, maintain a separate single-column Word version. If you need to submit immediately, paste your text into LinkTextFix to clean encoding errors, manually reorder any scrambled sections, and paste the corrected text directly into the ATS text field.
