Understanding Readability Scores

The Flesch Reading Ease score ranges from 0 (very difficult) to 100 (very easy) - aim for 60-70 for general audiences. Flesch-Kincaid Grade Level maps directly to US school grade levels. The Gunning Fog Index penalizes complex words (3+ syllables). To improve readability: break long sentences into shorter ones, replace jargon with simpler words, and use active voice instead of passive constructions.
