The word count is the number of words in a document or passage of text. Word counting may be needed when a text is required to stay within certain numbers of words. This may particularly be the case in academia, legal proceedings, journalism and advertising. Word count is commonly used by translators to determine the price for the translation job. Word counts may also be used to calculate measures of readability and to measure typing and reading speeds (usually in words per minute). When converting character counts to words, a measure of 5 or 6 characters to a word is generally used.
Different word counting programs may give varying results, depending on the definition of "word", on the text segmentation algorithms, and on whether words outside the main text such as footnotes or hidden text are counted.
In fiction 
Novelist Jane Smiley suggests that length is an important quality of the novel. However, novels can vary tremendously in length; Smiley lists novels as typically being between 100,000 and 175,000 words, while National Novel Writing Month requires its novels to be at least 50,000 words. There are no firm rules: for example the boundary between a novella and a novel is arbitrary and a literary work may be difficult to categorise. But while the length of a novel is to a large extent up to its writer, lengths may also vary by sub-genre; many chapter books for children start at a length of about 16,000 words, and a typical mystery novel might be in the 60,000 to 80,000 word range while a thriller could be over 100,000 words.
|Novel||over 40,000 words|
|Novella||17,500 to 40,000 words|
|Novelette||7,500 to 17,500 words|
|Short story||under 7,500 words|
In non-fiction 
The acceptable length of an academic thesis varies greatly, dependent predominantly on the subject. Many universities limit Ph.D. theses to at most 100,000 words, barring special permission for exceeding this limit.
