Key Takeaways

  • 1One-column resumes are the safest for ATS — use them for job boards and company portals.
  • 2Two-column resumes work when human reviewers matter (portfolio emails, LinkedIn outreach) but keep critical info in the main column.
  • 3Always test both versions: run parsing checks and an A/B application test to measure real results.
  • 4Follow formatting best practices: standard fonts, consistent dates, clear headings, and embedded fonts in PDFs.
  • 5Create two versions of your resume: an ATS-optimized one-column and a human-optimized two-column for outreach.
  • 6Use Resumize.ai to test parsing accuracy and generate an ATS-friendly version quickly.
  • 7Prioritize content parity when testing: only change layout, not wording, to get reliable results.

Conclusion

Frequently Asked Questions

Not automatically. Two-column resumes can parse correctly if critical information (names, job titles, dates) is kept in the main column and you avoid complex objects like tables. However, they carry higher risk, so always run a parsing test and keep an ATS-friendly one-column version as a backup.
Maintain at least two: an ATS-optimized one-column for job portals and a human-optimized two-column for direct outreach or portfolio submissions. Optionally keep a condensed one-page and an extended two-page version for different employer needs.
Create two identical-content resumes with different layouts and apply to similar roles (10–20 per version). Track interview invites and use parsing tools like Resumize.ai to measure extraction accuracy. A 10–15% difference in response rate is meaningful.
Yes — creative fields like UX/UI, design, and some marketing roles may benefit from a two-column layout to showcase visuals and skills. But even in creative fields, keep an ATS-friendly version for online applications.
