One column or two on a CV: what text extraction actually shows
One column or two? Most people choosing a CV layout ask this at some point. One column: safer, but more conventional. Two columns: more visual, but riskier. And the answer you find online depends mostly on which article you happen to land on.
Two opposite answers, both equally sure of themselves
Search for ‘one column vs two column CV’ and you’ll find answers that flatly contradict each other. Some guides quote a precise failure rate for two-column layouts. Others insist that ‘modern ATS handle two columns perfectly well in 2026’. Neither says how the figure was reached, on what sample or with which software.
A figure you can’t trace back isn’t data. It’s a claim dressed up as data. The real answer doesn’t fit in a percentage: it lies in how an applicant tracking system (ATS) reads a document.
What an ATS actually does with columns
An ATS doesn’t see two columns side by side. It receives a stream of text extracted in a certain order, and that order depends on how the document was built, not on how it looks on screen. On a single-column layout, the reading order is unambiguous: top to bottom, only one possible path. On a two-column layout, extraction can work in different ways depending on the engine: the left column then the right, or line by line, alternating between the two. In the second case, the result can pair a skill from the left column with a date from the right, and there’s no universal rule about what happens.
That variability, not a failure rate, is the real risk with two-column layouts: behaviour changes from one parsing engine to another, and nobody can see which one a given recruiter is using.
What we’ve verified, and what we haven’t yet
A single-column layout, with raw text extraction tested on two different rendering engines (wkhtmltopdf and Chromium), keeps the reading order intact: name, contact details, personal statement, work experience from most recent to oldest, education, skills. It’s a result you can check: anyone can repeat this test on a given PDF.
A two-column layout needs an extra step to be validated properly: a test against an advanced parsing engine, not just raw text extraction, because that type of engine reproduces the behaviour of today’s major recruitment platforms. Until that test has been done for a given layout, calling it ATS-friendly would mean doing exactly what we criticise other sources for on this subject: making a promise with no proof.
What this means when you choose a layout
For now, a single column is the only format whose reading by an ATS can be confirmed by a repeatable test, whatever engine is on the other side. That doesn’t mean a single-column layout has to be plain or understated: structure and typographic styling are two different things. It means the ‘two-column risk’ mentioned everywhere isn’t a myth to wave away, but an uncontrolled variable until it has been tested against the right kind of engine.
