Choose a tent that can comfortably fit all the people who will be using it. Tents are usually labeled with the number of people they can accommodate, but keep in mind that this is a rough estimate and you may want to choose a tent that is slightly larger than what you need.
Choose a tent that is appropriate for the season and weather conditions you will be facing. Three-season tents are suitable for spring, summer, and fall, while four-season tents are designed for winter use. Consider the tent's ventilation, waterproofing, and insulation when making your choice.
Choose a tent that is lightweight and easy to carry. If you will be backpacking, look for a tent that is under 4 pounds. If you will be car camping, weight is less of a concern.
Choose a tent that is easy to set up and take down. Look for a tent with color-coded poles, clips, and sleeves, and a simple and intuitive design.
Choose a tent with vestibules and storage options to keep your gear dry and organized.
