How it works
The tool counts words, sentences, and syllables from your pasted text. Syllables are approximated by counting vowel groups per word, subtracting silent endings (-e, -ed, -es) and adding a syllable for a consonant plus -le. The Flesch formulas use average sentence length (ASL = words ÷ sentences) and average syllables per word (ASW = syllables ÷ words). Reading time divides the word count by the words-per-minute rate. Chinese and Japanese have no spaces between words, so each Chinese or Japanese character counts as one word. All analysis runs in your browser.

Frequently asked questions
- What grade level should my writing be?
- For general web content and blogs, aim for grade 6–8. News articles typically target grade 8. Academic writing is often grade 12+. Plain-language guidelines recommend grade 8 or below for public-facing content.
- How do I lower my grade level?
- Use shorter sentences and simpler words. Break long sentences into two. Replace multi-syllable words with shorter synonyms. Active voice helps too.
- Is a lower grade level always better?
- Not always. Technical or academic writing for expert audiences can justify higher grade levels. The goal is to match the grade level to your target audience.
- How is the grade level calculated?
- Flesch-Kincaid Grade Level = 0.39 × (words ÷ sentences) + 11.8 × (syllables ÷ words) − 15.59 (Kincaid et al., 1975). The tool shows 0 instead of a negative grade for very simple text.
