The right tent size for three persons depends on how much space you will need to sleep comfortably while still being able to store the gear.

Normally, a three-person tent should comfortably accommodate three people and their gear. However, a slightly larger tent is always a better option, especially when a larger interior space is preferred or the equipment is larger than usual.

A three-person tent with a good size is typically between 45-55 square feet of floor space, just enough to add three sleeping bags and some gear to store inside.

Different manufacturers offer different sizes of tents; hence, checking the exact dimensions of the tent is something you need to do before exchanging your hard-earned money.

Well, a three-person tent size heavily depends on your preferences and what kind of backpacking trip you want.

A three-person tent is too big and heavy if you simply plan on backpacking alone or just with a single partner. Moreover, carrying it will be difficult as it is heavier than one or two-person tents and is not recommended if you travel long distances. Hence, opt for a smaller and lighter tent, like a one or two-person tent made specifically for 1-2 people when going on backpacking trips.

Using a three-person tent is a good choice if you are backpacking with two or more persons because it will provide enough space to sleep and store all your equipment. Another good thing is that some three-person tents do not weigh heavy and can be packed down into something smaller that is ideal to use if you plan on backpacking for several days.

Whatever your trip requires will be the main factor in the right tent size you should bring. Other factors you must consider include the tent’s weight, packability, and interior space before you get on with your exciting backpacking adventure.

The tent manufacturer and the models they offer will determine the size of the three-person tent. Usually, most three-person tenets are 45-55 square feet (4.2-5.1 square meters) in terms of floor area.

Aside from the manufacturer and specific tent models, factors such as design and shape will influence the tent's dimensions. In addition, most three-person tents are very comfy and spacious as it commonly has larger floor areas or a higher vertical wall design for more headroom for the persons staying inside the tent. In contrast, a 3-person backpacking tent will have a compact design and usually has a lower ceiling to lessen its weight and make it easier to carry around by the ones using it.

Remember that the dimensions of three-person tents will vary based on the slope of the walls, the number of doors and windows, and the placement of the windows, doors, poles, and guy lines. With that being said, it is vital to examine the tent's specifications beforehand rather than buying it immediately.

The answer to the question will entirely depend on the matress’ and the tent’s dimensions.

Usually, a standard queen-sized air mattress measures around 60 inches (152 cm) wide and 80 inches (203 cm) long. If you happen to have a tent with a floor area of approximately 45-55 square feet (4.2-5.1 square meters), then a queen-sized air mattress can fit in your tent. However, you might have to compromise some space that is supposed to be allotted for storing your gear.

The location of the poles and guy lines, the slope of the walls, and the shape of the tent can potentially reduce the overall space of the tent. Also, keep in mind that the presence of tapered or angled walls that is present in other three-person tents will also be a factor in making the tent have limited interior space.

It is best to check the exact dimensions of the mattress and the tent to guarantee that the mattress can fit perfectly inside the three-person tent you plan to purchase. In addition, ensure to consider the tent’s size, the number of people who plan on sleeping in the tent, and the gear that you need to place inside the tent.
