Common App essay attachment?

<p>Will it make a difference whether my essay is double spaced, indented, etc?</p>

<p>I indented my essay, but it was single spaced and I spaced between paragraphs as you would on any message board, such as this one, because I assumed it would be more readable and they didn't specify formatting.</p>

<p>Should I format attached essays in the standard, double spaced, university-style essay way or does it even matter?</p>

<p>I would do the general university-style.</p>
