Single Spacing vs. Double Spacing

For one of my apps, the question asks the essay to be 2-3 pages long. Should it be double or single? My English teacher says double spaced, but I’ve heard that it’s better to write as much as possible in the limit elsewhere so that you look like you have enough to say on the topic.

I’m typing up my essay right now, and I think it’ll be about two pages long single spaced. I can’t really add anything more to my essay w/o being redundant and repeating myself, but I don’t want the college (it’s also a safety which I would like to remain as a safety) to think that I was slacking off b/c I didn’t do 3 pages. Or maybe I’m just being paranoid.

<p>Unless the application says double spacing, use single spacing. Use font size of 12. Halvetica or Times Roman will look good.</p>
