Your tent should be large enough for you to stretch out properly. There is nothing worse than a tent that is too short, so be sure to pay attention to sizes.
Also, decide on how many people are going to be in your tent, and how much gear. If you have to sleep with all of your gear inside, then you will want to add another person to the tent size to accommodate for the additional items. Some tents are very tall and others even have rooms.
We also offer canopy style tents that are perfect for over a picnic table for eating and keeping the sun out.
