About the Tent Size Calculator
Tent manufacturers often rate capacity tightly, packing sleeping pads edge to edge. This calculator uses a more realistic square-footage-per-person guideline based on how much comfort you want.
Formula: Floor Area = Length × Width; Recommended Capacity = Floor Area ÷ Square Feet per Person, rounded down.
A "4-person" tent on the box often sleeps 2-3 people comfortably once gear is factored in — use the roomy setting if you want space for bags and stretching room.
