Sentence Counter tracks ten distinct metrics simultaneously from basic counts to readability formulas. Here is exactly what each one measures and why it matters for writing quality.
The Flesch Reading Ease formula, developed by Rudolf Flesch in 1948, is the most widely used readability metric in English. It scores text from 0 (extremely difficult) to 100 (very easy) based on average sentence length and average syllables per word. Use this table to interpret your score.
| Score | Difficulty | Grade Level | Typical Content |
|---|---|---|---|
| 90–100 | Very Easy | 5th grade | Simple children's books, beginner guides |
| 80–90 | Easy | 6th grade | Conversational language, basic news |
| 70–80 | Fairly Easy | 7th grade | Popular fiction, consumer journalism |
| 60–70 | Standard | 8th–9th grade | General web content, most blogs, Reuters |
| 50–60 | Fairly Difficult | 10th–12th grade | Academic articles, professional reports |
| 30–50 | Difficult | College level | Legal documents, scientific papers |
| 0–30 | Very Difficult | Professional | Technical manuals, medical literature |
