How big a tent do a family of 8 (2 adults, 6 kids) need?

Start from the sleeping surface: 2 adult pads at about 13 sq ft each and 6 youth pads at about 8 sq ft. Multiply by 1.6 for room to move, dress and reach the door, add about 3 sq ft per person for a duffel, and you arrive at 142 sq ft. Manufacturers allow roughly 16 sq ft per rated person, so that area corresponds to a 10-person rating. By the looser "30 sq ft per adult" comfort rule, the same floor sleeps about 4 adults in real comfort.

Dome or cabin tent for a family of 8?

At 10-person you are into large cabin and multi-room tents. Check the campsite pad size before you buy: many developed campgrounds have tent pads around 12 x 12 ft or smaller, and a 14 x 10 ft tent may not fit. Two mid-size tents are often easier to pitch and dry than one giant one.

Whatever the style, look at the floor dimensions rather than the person count, because two tents with the same rating can differ by 30 sq ft. Our tent picks for this size list the floor and peak height where the manufacturer publishes them.

Frequently asked questions

Can 8 people fit in a 8-person tent?

Physically yes, comfortably rarely. A 8-person rating means about 128 sq ft, enough for 8 standard pads edge to edge with nothing else on the floor. For car camping, where you have space in the car and want room to change and store bags, most people are happier with a 10-person tent of about 142 sq ft.

What size tent do a family of 8 (2 adults, 6 kids) need with cots?

Cots take more floor than pads, about 17 sq ft each against 13, and they need near-vertical walls. With cots and a duffel each the calculator lands on a 16-person tent. Pick a cabin-style tent so the walls do not lean in over the cot frames.

What if we bring a dog?

A large dog adds about 16 sq ft, which moves a family of 8 (2 adults, 6 kids) to a 10-person tent (about 158 sq ft). A small dog adds only about 6 sq ft and usually fits in the same tent if the gear stays in the car.
