They are 14 lines long, have a regular rhyme scheme and a strict metrical construction, usually iambic pentameter. Iambic pentameter means that each line has 10 syllables in five pairs, and that each pair has stress on the second syllable.  The characteristics of a sonnet (https://www.wisegeek.com/what-is-a-sonnet.htm) are its rhyme (https://www.wisegeek.com/what-is-a-rhyme.htm) scheme, its metric structure, its common topics, and its specific cultural conventions.
