Frequently Asked Questions
Why is the stated tent capacity often higher than reality?
Manufacturers rate capacity by fitting people shoulder-to-shoulder with no gear. Real comfort requires 0.9 m² per person.
What percentage of space should I reserve for gear?
30% is a good default for backpacking. Car camping with more gear may need 40–50%.
How does tent height affect capacity?
Height doesn't affect sleeping capacity but influences comfort. Tents under 1 m are difficult to sit up in.
