Check Your Resume Readability Score — ATS and Hiring Manager Tested

A hiring manager spends an average of 7.4 seconds on a resume before deciding to read further or move on. If your resume scores below 40 on the Flesch Reading Ease scale, those 7 seconds are spent parsing dense language instead of absorbing your qualifications. For ATS (Applicant Tracking Systems), overly complex language causes parsing errors that can misclassify your experience. Here is how to check and improve your resume readability.

Why Resume Readability Matters More Than You Think

Your resume has two audiences: a machine (ATS) and a human (hiring manager). Both prefer readable text, but for different reasons.

ATS parsing: Applicant Tracking Systems extract keywords, job titles, dates, and skills from your resume text. Complex sentence structures, uncommon formatting, and dense multi-clause sentences can confuse the parser. Simpler, more direct language parses more accurately — meaning your actual qualifications are more likely to be correctly identified and matched to the job requirements.

Human scanning: Recruiters do not read resumes. They scan them. Short bullet points with clear action verbs get absorbed in a glance. Long paragraphs describing your responsibilities in elaborate detail get skipped. The recruiter is looking for 3-5 key signals in those 7 seconds: relevant job title, years of experience, key skills, company names. Readable formatting helps those signals jump off the page.

Target Readability Scores for Resumes

Resume readability targets differ from blog or marketing content because the audience expects professional language:

Metric	Target	Why
Flesch Reading Ease	50-65	Professional but clear
Grade Level	9-12	Business-level writing
Avg words per sentence	12-18	Scannable bullet points
Gunning Fog Index	10-14	Professional without being dense

Do not aim for a Flesch score of 80 on your resume. That would sound overly simplified for a professional document. The goal is clear, direct professional writing — not casual or elementary language.

Paste your resume text into the readability scorer and check where you land. If your Flesch score is below 40, your resume is harder to read than most academic papers.

Common Resume Readability Problems and Fixes

Problem: Multi-clause job descriptions.

"Managed cross-functional team of 12 engineers and designers while simultaneously overseeing the migration of legacy systems to cloud infrastructure, resulting in a 40% reduction in operational costs." — This is 32 words. A recruiter loses the thread by word 15.

Fix: Break it into two bullet points. "Led 12-person cross-functional team (engineers and designers)." "Migrated legacy systems to cloud, cutting operational costs 40%."

Problem: Nominalization — turning verbs into nouns.

"Facilitated the implementation of..." becomes "Implemented." "Contributed to the development of..." becomes "Developed." Nominalizations add syllables without adding meaning.

Problem: Passive voice.

"Revenue targets were exceeded by 25%" becomes "Exceeded revenue targets by 25%." Active voice is shorter, clearer, and assigns credit to you — which is the point of a resume.

How to Check Your Resume Readability Score

1. Copy all the text from your resume (Ctrl+A, Ctrl+C in your document).
2. Open the Readability Scorer in any browser.
3. Paste your resume text into the input area.
4. Click "Analyze Readability."
5. Check your Flesch Reading Ease score (target: 50-65), average words per sentence (target: under 18), and overall grade level (target: 9-12).

If your scores are outside the target range, focus on the longest sentences first. The tool highlights long sentences, making it easy to find what to fix. Shorten the longest 5-10 sentences and re-check — you will see immediate improvement.

Also run your resume through the ATS Resume Checker to verify that your resume structure is ATS-compatible beyond just readability.

Industry-Specific Resume Readability Tips

• Tech/engineering: Technical terms are fine — "Kubernetes," "CI/CD pipeline," "microservices" are expected. But wrap them in short, scannable sentences. Avoid describing every technology you used in a single run-on bullet.
• Finance/legal: These industries expect formal language, so a Flesch score of 45-55 is acceptable. But still break complex sentences. A Goldman Sachs recruiter is scanning just like every other recruiter.
• Marketing/creative: You have more freedom to be conversational. Aim for 55-65 Flesch. Show your communication skills through clear, punchy writing.
• Healthcare: Medical terminology will lower your score naturally. That is fine — the recruiter expects it. Focus on keeping non-technical bullet points simple.
• Entry-level: You have less to say, so make every word count. Higher readability (60-70) works well because your resume should be concise by necessity.

Frequently Asked Questions

What readability score should a resume have?

Target a Flesch Reading Ease score of 50-65. This is professional-level writing that is still scannable by recruiters spending 7 seconds on your resume. Below 40 is too dense; above 70 may sound too casual for a professional document.

Does ATS care about readability?

ATS systems parse text structure, not readability scores directly. But simpler sentence structures parse more accurately, meaning your skills and experience are more likely to be correctly extracted and matched to job requirements.

How do I improve my resume readability score?

Start by breaking long bullet points into two shorter ones. Replace passive voice with active voice. Cut nominalizations (change "implementation of" to "implemented"). Aim for under 18 words per bullet point.

Can I check resume readability for free?

Yes. Paste your resume text into a free readability scorer to see Flesch-Kincaid, Gunning Fog, average sentence length, and grade level. No signup or account needed.
