Here's a frustrating truth: your resume might be getting rejected before a single human ever reads it. Most medium and large companies use ATS (Applicant Tracking System) software to filter applications automatically — and a surprising number of perfectly qualified candidates get screened out simply because of how their resume is formatted.
The good news? ATS formatting isn't complicated once you know the rules. And if you want to check how your current resume scores right now, you can use our free ATS Resume Checker — it takes under 60 seconds.
ATS software doesn't read your resume the way a human does. It scans for specific keywords, job titles, and section labels. If your layout is too complex — using tables, columns, or design elements — the system can't parse the content properly. It might misread your job title, skip your skills section entirely, or fail to find your contact details.
The result? A qualified candidate gets filtered out, and the recruiter never knows you applied. That's what we're trying to prevent.
Two-column resumes look clean to the human eye, but ATS parsers often read them left-to-right across both columns — turning your experience section into unreadable gibberish. Stick to a single column. It's boring by design, and that's exactly what you want.
ATS systems are trained to find headings like Summary, Work Experience, Education, and Skills. If you get creative and write "What I've Been Up To" or "My Story," the ATS won't recognize it as a work history section and will skip it. Use boring, standard headings — they work.
Arial, Calibri, Times New Roman, and Georgia are all safe choices. Keep font size between 10pt and 12pt for body text, and 14–16pt for your name at the top. Custom or decorative fonts can cause parsing errors — the ATS might misread characters or skip lines entirely.
PDF is usually the safest format because it preserves your layout across devices. But some older ATS systems handle DOCX better. When in doubt, read the job description — many explicitly state which format they prefer. What you should never use: image-based PDFs (scanned resumes), .pages files, or any format that isn't selectable text.
Tables are one of the most common ATS killers. They look organized on screen, but most ATS systems can't parse table content reliably. The same goes for text boxes, skill progress bars, icons, logos, and headshots. Strip all of it out. If your current resume has any of these, our formatting check tool will flag them for you.
ATS systems score resumes based on keyword matches. If the job description says "project management" and your resume says "led projects," you might not match — even though you have the skill. Mirror the exact language used in the job description, especially in your Skills and Experience sections. This is something CV Chackr's keyword analysis does automatically for you.
A lot of people put their phone number and email in the header or footer of their document. Some ATS systems don't scan headers and footers — meaning your contact info becomes invisible. Put your name, email, phone number, LinkedIn, and location in the main text area of the first page.
Here's a clean layout that works well across most ATS systems:
Even if you follow every rule above, it's worth running a quick check. Upload your resume to CV Chackr's free ATS checker and you'll get an instant score with a breakdown of exactly what's working and what needs fixing — formatting, keywords, and section completeness all in one report.
