How syllables are counted
English spelling and English pronunciation parted ways centuries ago, so no automatic syllable counter is perfect. This one uses the standard vowel-group method: it finds runs of vowels, then corrects for silent endings such as the e in make and the ed in walked.
On ordinary prose that lands within a couple of per cent of a dictionary count, which is ample for readability work. For poetry with a fixed metre, check the handful of words the algorithm is most likely to miss.
Words automatic counters commonly get wrong
Each of these is worth checking by ear if your form depends on an exact count.
- Words ending in -le after a consonant: little, table, gentle carry a syllable most rules drop.
- -ion and -ious endings: nation is two, curious is three, and both split unpredictably.
- Names and loanwords: pronunciation varies by speaker, so no rule can settle them.
- Regional differences: fire, hour and flower are one syllable to some speakers and two to others.
Syllables and readability
The Flesch reading ease score has two inputs: words per sentence and syllables per word. The second is a proxy for vocabulary difficulty, on the reasonable assumption that longer words are less common words. It is only a proxy — however has three syllables and everyone knows it, while writ has one and few people use it, but across a whole document it holds up well.
Common questions
How accurate is it?
Within roughly two per cent on ordinary English prose. Accuracy drops on proper nouns, technical vocabulary and loanwords, where pronunciation is genuinely contested rather than merely hard to compute.
Can I count syllables per line for a haiku?
Enter one line at a time to get an exact per-line figure. The line count in the panel confirms how many lines the tool sees.
Why does the count differ from my dictionary?
Dictionaries record pronunciation; this tool infers it from spelling. Where the two disagree, the dictionary is right. The common culprits are -le, -ion and -ious endings.
