A short story is usually a fictional story that is too short to be published by itself. Unlike a chapter book, it can usually be read or told in one sitting. In general, it is between 3 and 50 pages long and would take between 10-90 minutes to tell. Longer stories are novels (or novellas). Shorter stories are sometimes called short short stories or anecdotes.
A short story is less likely than a novel to have more than one author. It is also less likely to have a sub-plot. Short stories are often used in literature classes to demonstrate different literary techniques because they are quick. Short stories are often published in collections or within magazines.
