There wasn't an exact standard for dividing the number of words in short stories, short stories, medium-length novels, and full-length novels. It usually depended on the plot, characters, and theme of the novel. However, in general, short novels usually have fewer words, usually between a few thousand to ten thousand, short novels are less than ten thousand, medium-length novels are usually between a hundred thousand to one hundred and fifty thousand, and long novels are usually more than one hundred and fifty thousand. Of course, this was only a rough classification. In fact, the number of words in each novel would vary due to different factors.
