text: Uh... length? A novel is much longer. Besides that, there are some structural differences:\n\nA short story is more compact, and there is less room for character development. Author must choose to sacrifice plot points or development to keep his short story short. Often, short stories focus on only one, or at least very few central themes.\n\nA novel can be as long-winded as the author likes. Novels can incorporate a wide range of themes and ideas. There is unlimited room for character and plot development.\n\nThe difference lies in what the author must sacrifice in exchange for brevity.
