I realize sometimes there is confusion when it comes to e-book publications. Most e-books are categorized differently than a print book. Where a print books length is obvious based on the number of pages e-book standards don’t rely on page numbers for most devices. Sometimes you will see only a file size, but most publishers have attempted to let the reader know the length of a book by its number of words. Below is a list of generally accepted lengths.
The Science Fiction Writers of America define book lengths for their Nebula awards as follows:
- Short fiction: under 7,500 words
- Novelette: 7,501-17,500 words
- Novella: 17,501-40,000 words
- Novel: 40,001 words and up
