Should I use a single-column or a two-column resume?

Use a single-column resume for most applications, especially through online portals. Consider two columns mainly when a person, not software, will read your resume first and the side column holds only short items.

Why single column is the default:

• Applicant tracking systems generally read a single column from top to bottom without confusion.
• Recruiters can scan it quickly, including on a phone.
• It handles long job titles and bullet points without awkward wrapping.

When two columns can work:

• You are emailing your CV directly or handing it over at an event.
• You are in a field where a more designed look is common, such as marketing or design.
• The side column holds simple lists like languages, tools or contact details.

If you are unsure how your resume will be read, choose single column. If you like a two-column design, keep a single-column version too and use each where it fits best.
