What this free syllable counter does
Syllables set the rhythm of language. A haiku needs exactly seventeen of them, a spelling list is graded by them and a songwriter fits them to a melody. Counting by hand is slow and easy to get wrong. This free online syllable counter counts them for any word, sentence, poem or lyric, and does it line by line so you can see where a verse is too long or too short.
It also splits each word into syllables so you can see how the count was reached, charts the syllables in each line and checks your poem against a pattern, including haiku, tanka, limerick, sonnet lines and a custom pattern. Because every syllable counter makes mistakes with some words, there is a box to correct any word, and your fix applies everywhere that word appears. The tool runs in your browser and nothing is uploaded.
How to use the syllable counter
- Type or paste your text. For a poem or lyric, put each line on its own line.
- Read the totals: syllables, words and syllables per word.
- Look at the chart and table to see the count for every line.
- Correct any word that is wrong using the fix-a-word box, for example fire=2.
- Open the Words tab to see how each word is split and the spread of one-, two- and three-syllable words.
- Open the Poetry check tab, choose a pattern and see which lines match.
What counts as a syllable
A syllable is a beat of sound built around a vowel sound. Cat has one beat, cat-er-pil-lar has four. In English a syllable can also be built around a consonant that acts like a vowel, as in the second syllable of bottle. Counting by sound is easy for a speaker but hard for a program, because the spelling of English hides the sound. The word cake has two vowel letters in the middle and one beat, and real may be said with one or two beats depending on the accent.
The counter therefore uses a mix of rules and exceptions. It counts groups of vowels, adjusts for a silent final e and common endings such as -ed and -es, adds a beat for patterns like -ia and -io and looks up known tricky words. That is accurate for most everyday words. When it is not, use the correction box.
Rules of thumb for counting syllables
- Count the vowel sounds, not the vowel letters.
- A silent e at the end does not add a syllable: make has one, but able has two because of the le ending.
- -ed after t or d adds one (wanted has two) but not elsewhere (jumped has one).
- Two vowels together usually make one sound (rain, boat) but not always (poem, science).
- Consonant + le at the end is its own syllable (little has two).
- Compound words add the syllables of both parts (sunflower has three).
These rules cover most words, but there are many exceptions, which is why the counter keeps a list and offers a correction box.
Checking poems: haiku, tanka, limerick and sonnets
| Form | Syllables per line | Notes |
|---|---|---|
| Haiku | 5-7-5 | Three lines. Traditional Japanese haiku count sounds, which differ from English syllables. |
| Tanka | 5-7-5-7-7 | Five lines. |
| Limerick | about 8-8-5-5-8 | Rhyme scheme AABBA. Counts vary, and rhythm matters more than the count. |
| Sonnet | 10 per line | 14 lines in iambic pentameter. |
| Octosyllabic verse | 8 per line | Used in ballads and nursery rhymes. |
The poetry tab compares each line with the target. A green bar means the line matches. An orange bar means it is too long or too short, and the table says by how much. Remember that a count is only part of a form. Stress, rhyme and meaning matter as much, so read the poem aloud as well.
Counting syllables for songs and speeches
Songwriters match lines to a melody, and mismatched syllable counts are one of the quickest ways to make lyrics sound awkward. Put each lyric line on its own line, then compare lines in the chart. Lines that sit in the same position of each verse should usually have similar counts. The same method helps speechwriters and rappers who want a steady rhythm. Because the count is per line, you can quickly spot the one line that is longer than the rest and tighten it.
Syllables and readability
Words with more syllables tend to be harder to read. Readability formulas use this. Flesch Reading Ease divides syllables by words, so shorter words give an easier score. SMOG and the Gunning Fog index count words with three or more syllables, called polysyllabic or complex words. The totals on the first tab give you the same inputs: syllables per word and the count of words with three or more syllables. If a text feels dense, replace long words with short ones where the meaning allows. Use the word counter to see full readability scores for the same text.
For teachers, parents and learners
Syllable counting is a basic phonics skill. Children learn to clap or tap the beats in a word, which helps them to read and spell longer words. The word breakdown tab shows how a word splits, which can help with spelling lists and vocabulary work. Learners of English can use it to see how many beats a word has before they say it. The splits are a guide, because dictionary syllable breaks follow slightly different rules from spoken beats.
Tips for accurate counts
- Put each poem or lyric line on its own line.
- Check unusual names and words, and fix them in the correction box.
- Read the line aloud and tap the beats to confirm.
- Remember that accents change counts: fire can be one or two syllables.
- Turn the number option off if digits should not count.
- Do not rely on any program for a competition or exam without checking by ear.
Common mistakes
- Counting letters, not sounds. The number of vowel letters is not the number of syllables.
- Forgetting silent letters. Silent e and the -ed ending are often silent.
- Trusting names and foreign words. The rules were written for English words.
- Assuming one correct count. Some words can be said with different numbers of syllables.
- Forcing a form by count alone. A poem can match 5-7-5 and still not work.
Limits and privacy
The counter is rule-based and gives estimates. It handles English best and is less reliable for other languages, rare words, names and abbreviations. The word splits are approximate. Your text is processed in your browser and is not uploaded or stored.

Frequently asked questions
What is a syllable?
A syllable is a unit of sound in a word that has one vowel sound, with or without consonants around it. The word cat has one syllable, water has two and banana has three.
How do I count syllables in a word?
Say the word slowly and count the beats, or place a hand under your chin and count the times it drops. Our counter does this for you by analysing the spelling of each word.
How does this syllable counter work?
It checks each word against a list of known exceptions and then applies spelling rules, such as counting groups of vowels and ignoring a silent final e. The counts are estimates.
How accurate is the syllable counter?
It is accurate for most common English words, but English spelling has many exceptions, so names, foreign words and unusual words can be wrong. Use the fix-a-word box to correct any word.
Can I check a haiku?
Yes. Use the poetry check tab and choose Haiku. It compares each line with the 5-7-5 pattern and shows which lines are too long or too short.
Which poetry patterns can it check?
Haiku, tanka, limerick, sonnet lines, iambic pentameter, hexameter, octosyllabic lines and a custom pattern of your own.
How many syllables are in a limerick?
Limericks have five lines. The first, second and fifth lines are longer, usually eight or nine syllables, and the third and fourth are shorter at five or six. The tool uses a guide of 8, 8, 5, 5, 8.
What is iambic pentameter?
It is a line of ten syllables made of five pairs, where the stress falls on every second syllable. Shakespeare's sonnets use it. The tool checks the syllable count, not the stress.
Does it count numbers?
Yes. When the option is on, numbers are counted as they are spoken, so 42 counts as forty-two with three syllables. Turn the option off to ignore digits.
How are hyphenated words and contractions counted?
Hyphenated words are counted part by part. Contractions such as don't and we're are counted as spoken, one syllable each in these cases.
How do I fix a wrong count?
Enter the word and the right number in the fix-a-word box, such as fire=2. The counter uses your number everywhere that word appears.
Why do people count syllables?
Poets and songwriters count them to match a form or rhythm. Teachers use them for phonics and spelling. Writers use them to judge readability, because words with more syllables are harder to read.
What are polysyllabic words?
They are words with three or more syllables. A high share of them makes text harder to read, and readability formulas such as SMOG and Gunning Fog use them.
Can I use it for song lyrics?
Yes. Put each line of the song on its own line to see how many syllables it has, then compare lines in the chart to check the rhythm.
How do I print or save only the results?
Use the print or save button. The printout has the results, the chart and the tables only, not the page layout or the article. You can also copy the results or download a CSV file.
Is my text uploaded?
No. The counting happens in your browser and nothing is sent to a server or saved.
Is this syllable counter free?
Yes. It is free to use online with no sign-up and no limit.
