Frequently Asked Questions
The Flesch Reading Ease score rates text on a scale from 0 to 100 — the higher the score, the easier the text is to read. A score of 60–70 is considered standard (7th–8th grade level), while scores above 90 are very easy and below 30 are considered very difficult. It is calculated using average sentence length and average number of syllables per word.
The Flesch-Kincaid Grade Level translates the readability of text into a US school grade level. For example, a score of 8.0 means the text is appropriate for an 8th-grade student. Most general-audience web content aims for a grade level of 6–8.
The Gunning Fog Index estimates the years of formal education needed to understand a piece of writing on first reading. It penalises long sentences and complex words (three or more syllables). A score of 12 corresponds to high school level; below 8 is ideal for most audiences.
Reading time is estimated at 200 words per minute, which is an average silent reading speed for adults. For example, a 1,000-word article would have an estimated reading time of 5 minutes.
