About this tool
Enter the tent's floor length and width and how many people will sleep in it. The tool works out total floor area and area per person, with a plain verdict on roominess. It measures floor only: peak height and wall shape also affect comfort.
Frequently asked questions
What counts as roomy?
This tool calls 1 sq m or more per sleeper roomy, 0.7 to 1 snug, and under 0.7 cramped.
Does height matter?
Yes, but this tool measures floor area only; a low tent can still feel tight.
