Introduce a small trick to choose the size of the tent: not necessarily perfect, but very practical, measure the size of your sleeping pad, and then choose the size of the tent that matches it.
The more popular standard sleeping mat for military tents is 72 inches long and 20 inches wide (182.88cm long and 50.8cm wide). And width is a particularly critical criterion - according to this criterion, if you plan to choose a double tent, the tent must be at least 40 inches wide so that the person sleeping in it can barely sleep, and when two people sleep It will be crowded. In this way, if you want to sleep more comfortably, you have to choose a wider tent when choosing a tent. And if you often turn over when you sleep, the tent has to be wider.
Then choose the size of the base fabric of the tent according to this size. The size of the base fabric of the tent often has a lot to do with the sense of space and temperature in the tent. Of course, to be more precise, this indicator actually refers to the maximum width of a tent base fabric. Generally speaking, this maximum width often appears where the shoulders are when people are lying in the tent, and then the tent will gradually narrow at the feet, and at the same time, the top of the tent will gradually become lower. These will affect the space inside the tent. Of course, a spacious tent feels better to use, but such a tent will be relatively heavier.
Tips: If you are still likely to go on a hiking trip alone, or a long-distance biking trip, if this is the case, a 1-2 person account may be a better choice. If you plan to take a two-person trip, but occasionally invite a friend or relative, then you can consider a 2-3 person account, or buy a 3-person account directly. This will be more flexible, and can also provide you with more spacious space when in use.
