I am planning a camping trip with two friends. We need to buy a camping tent but I don't know what size of the tent is suitable for three people. I did a little search online and someone said should choose a tent which can accommodate two more person because there must be any space for the camping equipment. Is this true? Is a five man tent a little larger for three. Well, I have your answer right here. A five man tent is just fine. I do a lot of camping and I use a 2-3 person tent for just me, and a 4 person tent when I take the wife and kid along. Unless your back country camping you can't go wrong with getting a bigger roomier tent.
