Peer Recommender Help!

<p>Hi everyone, so my friend asked me to write her a peer recommendation. I've never done this before, so how long should it be? 1 page single spaced? Should I double space it? And do I have to include anything other than my letter if submitting via common app?</p>

<p>Thanks in advance! And any other advice would greatly be appreciated.</p>
