In English sonnets are most usually written in Iambic Pentameter: each line having ten syllables, with a stress on the even-number syllables:
earth HATH not ANyTHING to SHOW more FAIR
dull WOULD he BE of SOUL who COULD pass BY
There are other possibilities. Many sonnets are written as Iambic Hexameter (twelve syllable lines - Sidney's 'Loving in truth, and fain in verse my love to show') and some in Iambic Tetrameter (Catherine Chandler's Oneironaut - "My shrink said lucid dreaming tames / Recurring nightmares! What the bleep ..").
There are even trochaic sonnets.
But Iambic Pentameter is by far the commonest metre in an English Sonnet.
