Tent Size Calculator
Calculate the right tent size based on the number of occupants and gear storage needs.
Formula
Capacity = people × (22 sq ft × gear factor × comfort factor)
- Standard per-person floor area: 20-25 sq ft for comfortable sleeping.
- Tent manufacturers often rate capacity by tight sleeping, not comfortable use.
- Always size up one person from the manufacturer's rating for comfortable camping.
2 people, some gear, comfortable
Inputs
- Number of Sleepers: 2
- Gear Storage Needed: some
- Comfort Level: comfortable
2 × 22 × 1.25 × 1 = 55 sq ft needed. Recommend a 3-person tent.
