Syllable Counter

Type or paste any word, sentence, or passage to instantly count the syllables in each word and the total syllable count. Useful for poetry, haiku, and song lyrics.

How to use the Syllable Counter

  1. Choose your mode

    Select 'Single word' to count syllables in one word, 'Full text' to analyse an entire paragraph with per-word breakdowns, or 'Haiku validator' to check your haiku against the 5–7–5 syllable pattern.

  2. Single word mode

    Type any English word and the syllable count appears instantly in the result panel. Useful for checking pronunciation or verifying syllable counts for poetry.

  3. Full text mode

    Paste a sentence or paragraph and every word is annotated with its syllable count. The total syllable count appears at the top. Each word chip shows the count as a coloured badge.

  4. Haiku validator

    Enter your three haiku lines one by one. Each line shows its current syllable count vs. the target (5, 7, or 5). The border turns green when the count matches. A confirmation message appears when all three lines are correct.

About this Syllable Counter

Syllable counting is essential for haiku writing, poetry scansion, lyric composition, and language learning. Our syllable counter uses an algorithmic approach based on vowel sound detection and standard English pronunciation rules to give you reliable counts for most common words. The algorithm works by counting vowel groups in each word and then applying common rules: silent final 'e' subtracts a syllable, consonant + 'le' endings add one, and common exceptions for irregular words are handled via a lookup table. It follows standard American English pronunciation conventions. The haiku validator mode is particularly popular with creative writing students. A traditional Japanese haiku follows a strict 5–7–5 mora pattern. In English adaptations, the convention is 5 syllables in the first line, 7 in the second, and 5 in the third. Our validator checks each line independently and gives live feedback, making it easy to revise and refine your haiku until all three lines satisfy the syllable count.

Frequently Asked Questions

Count the number of vowel sounds in a word. Each distinct vowel sound = one syllable. For example, 'butterfly' has three vowel sounds (but-ter-fly) = 3 syllables. Silent vowels and vowel combinations can make this tricky.

A traditional haiku has three lines with a 5-7-5 syllable pattern: 5 syllables in the first line, 7 in the second, and 5 in the third. Our syllable counter can help you verify each line as you write.

Syllable division can vary by dialect, pronunciation style, and whether you're counting spoken vs. written syllables. Words like 'fire' can be counted as one or two syllables depending on regional accent. Our counter uses the most common American English pronunciation.

Traditional Japanese haiku uses 5–7–5 mora (phonetic units), not syllables — the distinction matters in Japanese but less so in English. Modern English haiku writers sometimes follow the 5–7–5 syllable rule strictly, while others treat it loosely, focusing more on the spirit of the form (a seasonal reference, a juxtaposition, a moment of clarity) than the exact count.
