Understanding how applicant tracking systems (ATS) handle resume columns is crucial for creating a format that is both visually appealing and machine-readable. While many job seekers focus on content, the layout and structure—particularly columns—play a significant role in how ATS parses your resume.

How ATS Processes Resume Columns

ATS software scans resumes to extract relevant information such as work experience, education, and skills. How it interprets columns depends on the system’s design, but generally, ATS tools are optimized to read linear, straightforward layouts.

  • ATS typically reads resumes from top to bottom, left to right, similar to how a person reads a page.
  • Columns that contain multiple sections side by side can confuse ATS if the content isn't clearly separated or if the system isn't designed to handle complex layouts.
  • Many ATS software parses text based on spacing, headers, and formatting cues rather than visual columns.

Common Pitfalls of Using Columns in Resumes

Using columns can sometimes lead to information being missed or misinterpreted by ATS. For example, when different sections are placed side by side, the system might only read one column or merge content incorrectly.

  • Placing important details in narrow columns may cause the ATS to overlook or truncate information.
  • Using complex formatting, such as nested tables or multi-column layouts, can hinder ATS parsing.
  • Inconsistent spacing or headers within columns can make it difficult for ATS to accurately categorize data.

Best Practices for Structuring Resume Columns

To ensure your resume is ATS-friendly, focus on clarity and simplicity in your layout. When using columns, do so thoughtfully, keeping in mind how ATS software reads your document.

  1. Use a single-column format for the main sections of your resume, such as experience, education, and skills.
  2. If you want to use columns for aesthetic reasons, limit them to visual design elements like headers or small info boxes that do not contain critical data.
  3. Avoid nested tables, multi-column layouts, or text boxes that can disrupt ATS parsing.
  4. Always test your resume in a plain text format or with ATS simulation tools to see how it reads your layout.

For instance, if you want to display your skills alongside your experience, consider listing skills in a separate section or using simple bullet points rather than placing them in a side-by-side column.

A straightforward, linear layout often yields the best results for ATS, ensuring your information is parsed accurately and efficiently.

Practical Example: Optimizing a Resume with Columns

Suppose you have a resume with two columns: the left column contains your contact info, skills, and certifications; the right column has your work experience and education. While visually appealing, many ATS might only read the left column or merge the content improperly.

To optimize, convert the columns into a single, continuous layout. Keep contact info at the top, followed by experience, education, and skills in separate, clearly labeled sections. This approach ensures that ATS systems can parse all your information correctly.

Final Tips for Resume Column Optimization

  • Stick to simple, linear layouts for critical information.
  • Use standard section headers like “Work Experience,” “Skills,” and “Education.”
  • Test your resume in plain text or ATS simulators to verify how it reads your formatting.
  • Avoid complex formatting features such as nested tables, text boxes, or multi-column sections.
