Family camping tents come in a variety of sizes and shapes. What suits your requirements may not work for others. This is why so many variations are produced for the outdoor enthusiast market.
Tents have four main forms: umbrella, A-frame, geodesic, or "dome" and walls. The A-frame has the traditional shape of an old-style tent, but can also be quite large. To get more details about the army tent, you may visit https://www.usmilitarytents.com/.

Umbrellas are the usual family tents with plenty of room to stay in, including large windows and rain flies. The geodesic dome has many variations with different combinations of connected triangles.
These wall tents are similar to A-frame tents, but are usually larger and have vertical sidewalls. It is most often used in army applications and scout camps (usually on a permanent deck).
Tents with square plinths are more effective in placing bedrooms and facilities. If you choose a tent with a round or oval bottom, you'll need to provide extra floor space to compensate for the less effective layout.
Tents are available in the market as two, four, six, etc. At best, it describes the vast majority of people you can cram into a sleeping tent without storage space for personal items. This size is fine for tourists carrying light items, but not unreasonable for the casual camper.
