How many words should be on a page in like size 12 Times New Roman (not double spaced). My friend said it should be around 300, but I always end up getting around 500, so I dunno....
The number of words on a page is irrelevant. It depends completely on formatting. In a manuscript formatted for submission to an agent or editor who demands Courier New 12pt double spaced with one-inch margins, there will be around 230, more or less depending on the amount of short-line dialog. In a printed book, it depends on the page size and font used. Don't worry about word-per-page counts. Only the total word count counts.
Keep in mind the 250 WPP formula only works when using Courier 12 pt with 1 inch margins and widow line control turned off.
