Layout Details & FAQs

Is the Creative Sidebar template ATS-friendly?

Yes. All our templates are designed following strict parsing rules. The layout structure avoids text boxes, custom icons, or complex horizontal layouts that confuse parsing algorithms.

Can I customize the margins on the Creative Sidebar layout?

Absolutely. In the KAD CV builder, you can customize margins, text sizes, line spacing, and color schemes dynamically, and download the print-ready PDF instantly.

Does the Creative Sidebar layout use horizontal divider lines that interfere with ATS?

No. While some legacy parsers had issues with complex graphical borders, modern ATS engines (like Greenhouse or Workday) ignore CSS-based horizontal border lines and parse the underlying text streams perfectly. Our layouts use semantic borders for visual organization without impacting parser readability.

What is the best font to use on a resume for ATS compatibility?

Standard, web-safe sans-serif fonts (like Arial, Inter, or system-ui) are best for modern parsers. Serif fonts (like Times New Roman or Georgia) are also fully supported. Avoid using rare custom fonts or icon-based webfonts, as parsers may fail to map the characters correctly, resulting in blank or gibberish outputs.
