The size of a one-person tent differs depending on the brand, model, and type of the tent. Naturally, a one-person tent accommodates one adult, including the gear they brought comfortably. The standard dimensions of a one-person tent are about 84-90 inches (213-229 cm) in length, 30-40 inches (76-102 cm) in width, and 36-48 inches (91-122 cm) in height. However, keep in mind that the tent's dimensions will vary depending on the tent's design, which is why it is important to look at the specifications given by the manufacturer to ensure that the tent you purchase will suit your needs.
