Choosing the Right Reading Level for Your Audience
Published October 03, 2025 • 8–12 min read
A decision framework for selecting appropriate readability targets by domain, risk, and user intent.
Map Audience and Risk
For low‑risk content (blog intros, marketing), aim higher Flesch (65–90). For high‑risk (finance, healthcare), favor clarity and definitions, even if the score drops. Consider the consequences of misunderstanding.
Consider Context and Channel
Mobile users skim; shorten sentences and lead with outcomes. For email, aim for 70–90. For API docs or legal notes, accept 40–60 but add summaries and examples.
Test, Don’t Assume
Run usability sessions with 5–7 people. Ask them to explain a paragraph in their own words. If they paraphrase accurately, your level is right. If not, iterate and test again.
Localization
Plain language translates better. Avoid idioms and culture‑bound references. Keep measurements and dates locale‑appropriate. Consider building a glossary.
Governance
Document targets by page type and add them to your editorial checklist. Review quarterly as products and audiences change.
