Exemples
Aiming for general-audience writing
For a blog, a landing page, or marketing copy, the target is Flesch Reading Ease 60+ (8th-9th grade). If your score is below 50, your text is college-level — most of your audience will bounce.
The utilization of synergistic optimization paradigms facilitates the operationalization of comprehensive deliverables.
Résultat : Flesch Reading Ease ~5, Flesch-Kincaid Grade ~20. Way above the average reader. Rewrite in plain English.
Checking academic writing
For a journal article, a textbook, or technical documentation, Flesch-Kincaid Grade 12-16 is normal. Below 10 reads as too casual; above 18 reads as needlessly dense.
The results demonstrate a statistically significant correlation (p < 0.05) between exposure and outcome.
Résultat : Flesch-Kincaid Grade ~12. Appropriate for a journal or technical doc.
