A 750-word essay comes out to approximately three typed pages, but this can vary depending on the page formatting and font style and size. Standard formatting is 1-inch margins, with a widely accepted font, such as Times New Roman or Arial, set at 12 point.
Whether the paper is double or single spaced and how big the words are also makes a difference. A 750-word paper with a large percentage of shorter words is going to be shorter than one where the average word is three or more syllables long. There are sites that allow writers to convert words to approximate page lengths based on the particular font and size.
