When choosing the size of the tent, there are a few things to consider. The name of the tent often tells you how many people will fit in the tent. Feel free to look at the dimensions of the tent, because the sleeping pads you intend to use must fit both in width and in length. When talking and choosing the right tunnel tent, many people choose to upgrade to a 3-person model, even if only 2 of you will be using the tent. The extra space is usually appreciated as you have room for a wider sleeping pad and you can also store some of the equipment if you want to have it close at hand inside the tent.
