Pages: 0. There are times when it helps to know how many words per page you're writing. While a general guideline is one page is 500 words (single spaced) or 250 words (double spaced), this is a ballpark figure. The truth is the number of words per page depends on a variety of factors such as the type of font, the font size, spacing elements, margin spacing, and paragraph length to name a few.
For a page with 1 inch margins, 12 point Times New Roman font, and minimal spacing elements, a good rule of thumb is 500 words for a single spaced page and 250 words for a double spaced page. Using this as an example, a 3-4 page double spaced paper is 750-1000 words, and a 7 page double spaced paper would be 1750 words. Assignments often specify a research paper or essay length in terms of words, rather than pages - a paper of 750-1000 words or a paper of 1500-1750 words. This way a student's paper will still meet their instructor's length expectations, regardless of varying font size, margin size, or use spacing elements.
