Worked example
For The quick brown fox jumps over the lazy dog near the river bank. (13 words, 1 sentence, 16 syllables), the Flesch Reading Ease score is 89.5 and the Flesch-Kincaid grade is 4.0.
What this tool does not do / Limits
Syllables are estimated by counting vowel groups, with a silent-e adjustment, so scores are close but not exact. The scores describe surface difficulty only, not accuracy, interest or suitability for a reader.
Frequently asked questions
What does a high Reading Ease score mean?
Higher means easier to read: 90-100 is very easy, 60-70 is plain English, and below 30 is very hard.
Why is the syllable count estimated?
Exact syllables need a dictionary; vowel-group counting is a standard approximation that is close for most ordinary words.
