Syllable Counter
Paste any text and we estimate the number of syllables, plus the word and sentence counts and the average syllables per word. Useful for poetry, songwriting, ESL practice, and tightening prose for readability.
Counts update live. Nothing is sent to a server. Syllable counts are estimates — English pronunciation has many exceptions.

"The quick brown fox jumps over the lazy dog."
9 words · 11 syllables · 1.22 syl/word
"Education improves understanding."
3 words · 12 syllables · 4.00 syl/word
"Cat sat on a mat."
5 words · 5 syllables · 1.00 syl/word
How it works
For each word, we lowercase it, strip non-letters, count groups of contiguous vowels (a, e, i, o, u, y), and adjust for silent-e endings. The result is at least 1 for any non-empty word.
Per word · count vowel groups − silent e (max 1 floor)
English pronunciation has many exceptions. Treat the count as an estimate, especially for proper nouns, loanwords, and technical vocabulary.
Frequently asked questions
A syllable is a unit of sound that contains a single vowel sound, with or without surrounding consonants. The word "banana" has three syllables: ba-nan-a. Counting them is foundational to readability scores, poetry meter, and second-language learning.
English pronunciation is irregular. Words like "fire" can be one syllable for some speakers and two for others, and silent letters ("knight", "isle") complicate any rule-based count. The calculator uses a vowel-group heuristic that's accurate for most words but won't match every edge case.
Aim for shorter words and simpler sentence structure. Average syllables per word is one of the inputs to the Flesch readability formulas — bringing it down (closer to 1.5) makes text more accessible. Long words aren't bad, but a steady drumbeat of multi-syllable words slows readers.
Only loosely. The heuristic is tuned for English vowel patterns. Words from other languages may be miscounted, especially those with vowel clusters that English doesn't share (e.g., Welsh, Hawaiian, Finnish). For serious linguistic work, use a phonetic dictionary instead.
