Never go over 500 words for a page with the page limit essays. I use 11 pt Times (smallest font), 1.9 spacing, 0.5-0.7" margins on all sides. Just stay uniform.
Stanford is tough because they specify 12 pt font, so I play with margins and line spacing a little. They want you to write "what matters to you most and why" in 3 pages (roughly 1200 words). Yeah right...
Perhaps this is a silly question but, how do you count words? If I crank up the wayback machine and transport the assembled masses back in time to to my secondary school typing class* a "word" = any five characters (including spaces) and a "page" = 250 words. Now, my Quark skills will certainly allow me to squish more than 250 words on a page... but I assume that instructions calling for a limit of three pages indicate an essay that is well under a 1000 words. I wonder where the limit lies. I don't think it takes a deep understanding of typefaces on the reader's part to comprehend when a particular essay is trying to game the suggested limit.
*Just to make clear how "old school" this was... typing class was undertaken in room full of manual typewriters. The T/A's were all football players - perhaps they figured typing was another form of calisthenics.
