How to figure beam size

How do I figure the size of a beam that will span 13 feet?
I am building a shelter for my 25 foot travel trailer using 6x6 posts.

need more info. jack
is this in a bearing wall or non-load bearing wall
will you have to contend with snow load
do you intend to use the 6x6s for the posts only or where you intending to span 13'-0" with the 6x6s as well.
is the shelter enclosed or open sides (wind loads could be different)
Can the beam extend beyond the 13' width or do you intend to 'hang' the beam between two posts that are 13' apart.
