Typically, the length of a novel is measured by the number of words. However, in the publishing world, it can also be categorized in a more general sense such as short novel (usually under 40,000 words), novella (around 40,000 - 60,000 words), and novel (over 60,000 words). Another way could be by the number of pages, but this can be less accurate as it depends on factors like font size, page margins, and line spacing.
The length of a novel is mainly measured in terms of word count. Publishers often have guidelines based on word count for different types of novels. For instance, a short - length novel might be around 20,000 - 40,000 words, which is suitable for quick reads or for certain markets. Novellas fall in a middle range, and then full - length novels can range from 60,000 words upwards. Page numbers can also give an indication, but it's not as reliable because of the various formatting options that can change the page count without changing the actual content.
