The appropriate length of words for a novel submitted to a publishing house would vary according to the requirements and standards of different publishing houses. However, in general, a novel should have between one million and two million words to ensure that the story had enough length and depth to attract the reader's interest. In addition, the structure of the word count needed to be considered when submitting. Usually, the beginning and end of the story should be left with enough words to allow the reader to better understand the background and character setting of the story. In the middle part, the word count needed to be allocated according to the plot and theme of the story to achieve a smoother reading experience. Therefore, when submitting a novel, it is recommended to carefully read the submission guidelines and requirements of the publishing house before submitting it to ensure that it meets their expectations. At the same time, you can calculate the total word count of the story and adjust the word count range according to the word count and story length requirements to ensure that the submission meets the requirements.
