Short answer
A novella occupies the literary middle ground between a short story and a novel, but that boundary is not universally fixed. The Nebula Awards make it exact for their categories: a novella has 17,500–39,999 words; a novel has at least 40,000. Those rules classify award entries, not all English-language fiction. 1 2

| Question or attribute | Novella | Novel |
|---|---|---|
| Literary position | Between short story and novel | Longer form used as the comparison point |
| Nebula word count | At least 17,500; below 40,000 | 40,000 or more |
| Boundary status | Disputed outside a specified system | No universal minimum established here |
| Terminology complication | May be called a short novel | “Short novel” can overlap with novella usage |
The literary comparison and award thresholds answer different questions. 1 2
What each thing is
In literary discussion, “novella” names a form, not merely a numerical interval. Colorado State University’s essay describes it as combining elements associated with shorter and longer fiction. “Novel” supplies the longer-form reference point; the essay does not offer a comprehensive definition of its structure or scope. 1
Key differences
Length becomes decisive when a classification system expressly makes it decisive. The Nebula rules separate novella and novel at 40,000 words. Literary commentary is less exact: the CSU essay reports approximate transition points around 20,000 and 40,000 words while emphasizing that the territory between forms resists tidy categorization. 1 2
How to tell them apart
First identify the context, then apply its criteria. For a Nebula length classification, count words and use the published thresholds. For a literary label, that count is evidence rather than a final verdict: the CSU discussion does not establish a reliable checklist based on characters, issues explored, or narrative architecture. 1 2
Where they overlap
The phrase “short novel” exposes the overlap in naming. The CSU essay reports that Katherine Anne Porter preferred that term for works discussed as novellas. Consequently, a work called a short novel is not necessarily being distinguished from a novella; the wording may reflect a writer’s preferred vocabulary. 1
Edge cases
Exactly 40,000 words belongs in the Nebula novel category, not novella. Another complication is serialization: the rules permit a serialized novel to be nominated in part or whole, provided the nominated section meets the relevant year and category word-count requirements. Classification therefore requires attention to what portion is nominated. 2
Why the distinction exists
The award rules provide explicit categories for administering nominations and eligibility; the literary essay explores the expressive possibilities of an unsettled form. These are different classification tasks. The supplied material does not document publishers’ thresholds or their reasons, so it cannot establish why a particular publisher draws a different line. 1 2
Common misconceptions
“Novelette” is not always interchangeable with “novella.” Although the CSU essay presents fluid borderland terminology, the Nebula rules distinguish the two: novelettes run from 7,500 words to fewer than 17,500. Likewise, treating 40,000 as an absolute literary boundary mistakes a specific award rule for a universal definition. 1 2
Examples
Consider two hypothetical manuscripts. At 18,000 words, one fits the Nebula novella bracket despite falling below the approximate 20,000-word transition discussed in the CSU essay. At exactly 40,000 words, another fits the Nebula novel bracket even if its author favors the literary description “short novel.” The context resolves the award label, not every naming dispute. 1 2
