How this haiku checker works
- Write your three lines. Type or paste one line into each box.
- Watch the badges. Each line shows its syllable count against its target: 5, then 7, then 5. A line that fits turns green.
- Read the hints and correct words. Lines that are short or long say by how many. If a word looks wrong, click it and fix the count.
The counts come from the same engine as the syllable counter: a dictionary-based list of exceptions plus counting rules. It is an estimate, and it does not split words into syllables. It also does not judge the poem. It checks the pattern.
About 5-7-5
Five-seven-five is the pattern most people learn first, and it is worth knowing where it comes from. The Haiku Society of America’s 2004 definitions say that a typical Japanese haiku has seventeen “sounds” (on) arranged five, seven and five, and that most haiku in English consist of three unrhymed lines of seventeen or fewer syllables, with the middle line longest. Japanese on are counted differently from English syllables, so 5-7-5 in English is an adaptation rather than a direct translation, and many modern English haiku do not follow it.
The Society’s current definition describes a haiku as a short poem that uses imagistic language to convey the essence of an experience of nature or the season. It does not mention a syllable count. So treat 5-7-5 as a useful exercise and a familiar form, not as a rule that makes a poem a haiku.
Tips for a 5-7-5 that works
Start with the image
Write down what you saw: a frog in a pond, frost on a gate, a train going by. Then fit it to the pattern. Starting from the count tends to produce padding words that do nothing for the poem.
Cut the filler
If a line is over, remove adjectives and “the” before you remove the image. If a line is short, look for a more exact word before you add a vague one. A single precise detail does more than two general ones.
Say it out loud
Syllable counts depend on how you pronounce words. Read each line aloud and tap the beats. If your own count differs from the badge, correct the word. The checker is following you.
Try a break in the middle
Many haiku pair two images and let the reader feel the link, with a small pause between them. The Society’s current definition mentions this kind of cut between images. A break after line one or two is a simple way to try it.
When the count is close but the line is wrong
A line that is one syllable off is usually a sign that a word can be swapped, not that the idea is wrong. Try a shorter or longer word with the same meaning, move a word to another line, or change “the” to “a” if that fixes the beat. If you cannot get 5-7-5 without squeezing the image, consider keeping the image and letting the count go. Plenty of respected English haiku do exactly that.
Where to go from here
For longer pieces, paste a whole poem into the syllable counter to get a total for every line. For something to write about, try the writing prompts, or the mindfulness theme in the journal prompts, which ask you to describe what is in front of you, a good start for a haiku.
