Are Two-Column Resumes ATS-Friendly? (Tested)
2 min read
Two-column resumes look efficient — a tidy sidebar for skills, the main column for experience. But that sidebar is also the single most common reason content gets scrambled by an Applicant Tracking System (ATS). Here's the honest, tested answer.
The short answer
Single-column resumes parse more reliably than two-column ones. In testing across major ATS platforms, single-column layouts land around ~93% parsing accuracy, while even well-built two-column resumes come in around ~86%. That gap is concentrated in specific systems — notably Taleo and older iCIMS — which a large share of big employers still run.
So two-column resumes can work, but you're rolling the dice on which ATS reads them, and the downside (your experience getting jumbled) is severe.
Why two-column resumes fail
ATS parsers read a document as a continuous, linear stream — left to right, top to bottom. A two-column layout is almost always built with a table, text boxes, or a sidebar element under the hood. When the parser hits that, it often slices horizontally across the whole page instead of finishing one column before moving on.
The result: your "Skills" sidebar gets interleaved into a 2021 job description, dates attach to the wrong roles, and the clean design becomes unreadable data. The columns aren't the problem by themselves — the tables and text boxes used to create them are.
If you insist on two columns
Sometimes a two-column layout is fine — for example, when:
- You're applying directly by email or through a small company with no ATS.
- You know the employer uses a column-tolerant system (Greenhouse, Lever).
- You're in a creative field where presentation is part of the pitch.
If you go this route, put the essential info — contact details and work experience — in the main/left column so it's read first, and avoid tables/text boxes where possible.
The safer default
For most online applications, use a single column. It's the format that parses most reliably everywhere, and it doesn't cost you anything a recruiter actually values. A clean single-column resume isn't "boring" to an ATS — it's readable, which is the entire goal. See the full rules in the ATS-friendly resume format guide, and the broader list of formatting mistakes that break ATS.
Already have a two-column resume?
You don't need to rebuild it. Upload it to ResumeToATS and it extracts your content and re-emits it as a clean, single-column document — PDF, Word, or Markdown — with your wording intact. It's the quickest way to go from a parsing-risky layout to a parser-safe one.
Bottom line
Two-column resumes parse worse, fail hardest on the enterprise systems big companies use, and the failure mode is your experience getting scrambled. Unless you're certain an ATS isn't involved, go single-column — or convert your existing two-column resume into one in a couple of minutes.
