A short story is a fictional work typically ranging from 1,000 to 7,000 words. For comparison, novels are much longer, usually between 50,000 and 200,000 words. This word count is a primary defining characteristic, setting it apart from longer fictional forms.

Beyond word count, a short story is fictional, unlike essays which are non-fiction. It usually features a main character, a central event, and a resolution or an indication of one. It's a complete narrative with a clear beginning, middle, and end, not merely a scene from a larger work.

Due to word constraints, short stories often avoid multiple subplots, numerous secondary characters, or extensive changes in location. They typically center on a single, pivotal moment in a character's life where something significant changes, exploring the implications of that change or the lead-up to it. It's a small-scale narrative focusing on one important event rather than an entire life story.

A short story is not merely a truncated novel. It is defined by its concise structure, typically portraying a single character's journey centered around a transformative moment or choice. Despite potential variations in form, the core definition hinges on its word count and its focused, compact narrative arc.
