Our scaled drawings shows you an idea on how much space each size of a wall tent has to offer. Go too small, you will not be comfortable and if the tent is too large it can be frustrating to set up by yourself. Your first decision should be the size of the tent you will need for the gear you are planning to use and the reason for your trip.
A good general rule is, a little bigger is better. One of the first things to discuss is the term cut size. This refers to the size that the fabric would be before it is sewn. When sewn together, the seams and hems reduce the actual finished size of the product. It is not uncommon in tents for the finished dimensions to be 3-6″ less than the cut dimensions.
