The main difference between Paragraph and Stanza is that the Paragraph is a a portion of text composed of one or more sentences and Stanza is a grouped set of lines within a poem. ... Some stanzaic forms are simple, such as four-line quatrains. Other forms are more complex, such as the Spenserian stanza.
Stanzas in poetry are similar to paragraphs in prose. Both stanzas and paragraphs include connected thoughts, and are set off by a space. The number of lines varies in different kinds of stanzas, but it is uncommon for a stanza to have more than twelve lines. Have a nice day!
