Why one column is safer
A one-column resume is easier for ATS software to parse because the reading order is simple. The system can move from top to bottom without deciding how to combine sidebars, columns or separate blocks.
This reduces the risk of job titles, skills, dates and experience being mixed together.
The ideal order
- Contact information.
- Professional summary.
- Work experience.
- Education.
- Skills.
- Certifications.
- Projects or additional sections.
Why two columns can fail
Two-column resumes often place skills, languages or contact details in a sidebar while experience appears in the main column.
A parser may read the sidebar first, mix it into the work experience section or attach dates and skills to the wrong part of the resume.
How to make one column look professional
- Use bold headings.
- Use consistent spacing.
- Use clear bullet points.
- Keep each role structured in the same way.
- Use standard fonts.
- Avoid large blocks of text.
- Use concise achievement-focused bullets.
When to use a visual version
You can still keep a more visual resume for networking, direct messages or interviews.
For job portals and online applications, a one-column ATS-friendly version is usually the safer default.
