What is Readability?

Flesch Reading Ease

Scores 0–100. Higher = easier. Blog posts should score 60–70. Academic papers typically score 30–50. Aim for 60+ for general audiences.

FK Grade Level

The US school grade needed to understand the text. A score of 8 means an 8th grader can read it. Target 6–8 for web content.

Gunning Fog Index

Estimates years of formal education needed. Under 12 is good for most audiences. Newspapers aim for 10–12.

SMOG Grade

Simple Measure of Gobbledygook. Counts polysyllabic words. Good for health and medical content where precision matters.

Why Readability Matters for Your Content

Studies show that most online content is read at a 7th-8th grade reading level — regardless of the audience's actual education level. Complex text causes readers to disengage: they skim, miss key points, or leave entirely. This matters for blog posts, landing pages, emails, documentation, and any content where you want the reader to understand and act on your message.

ReadClear uses multiple readability formulas including Flesch-Kincaid Grade Level, Gunning Fog Index, and SMOG Score to give you a complete picture of your text's complexity. Each formula weighs different factors (sentence length, word length, syllable count) differently, so seeing multiple scores together gives a more reliable assessment than any single formula alone.
