Some of the more common practices in English include: three lines of up to 17 syllables; a season word (kigo); a cut or kire (sometimes indicated by a punctuation mark) to compare two images implicitly.
English haiku do not adhere to the strict syllable count found in Japanese haiku, and the typical length of haiku appearing in the main English-language journals is 10–14 syllables.
Some haiku poets are concerned with their haiku being expressed in one breath and the extent to which their haiku focus on "showing" as opposed to "telling". This is the genius of haiku using an economy of words to paint a multi-tiered painting, without "telling all". Or as Matsuo Bashō puts it, "The haiku that reveals seventy to eighty percent of its subject is good. Those that reveal fifty to sixty percent, we never tire of."
