There are several important factors you need to consider when choosing the right tent. If you don't pay attention to these, you might be totally disappointed with your choice of tent. In my opinion, always choose military surplus tents for camping. You can get more detail about tents via https://www.usmilitarytents.com/.
The most important factor to consider is the size. Do not rely on the rating of the manufacturer for the number of people who will fit in the tent. Very few people are happy when using a four-person tent for four people.
First, figure out the actual size you will need, i.e. the number of people who will be sleeping in it. Will you be using an inflatable mattress, sleeping bags, etc? Lay your bedding out and then decide if you need additional space for gear etc.
Also, it is necessary to be able to stand up inside because many tents are not high enough for this. Once you have determined the necessary size requirements, then you will know the size of tent you will need.
Ease of Setting Up
Most people don't want to spend much time setting up their tent, especially if they are not experienced campers. Some tents are very easy to set up and others aren't. Some are designed so only one person can set it up alone, others require two people. Again, don't rely on how long the manufacturer says it will take.
