For all the engineers in our midst…
Despite having spent years in the industry, I still don't understand how manufacturers get many of their floor area figures. It seems like 80% of the time when I measure a tent floor, the area isn't particularly close to the manufacturer's stated specs.
Case in point: Big Agnes Copper Spur UL 3. Stated area of 44 square feet. Actual floor measurement: 5'1" x 84", or 35.6 square feet. Slightly more complicated, Mountain Hardwear Stiletto 1, reported as 28 square feet. Non-rectangular, so my calcs are rough, but actual area measurements come out at about 19 square feet. What are they smoking?
At first I thought they were double-reporting vestibule area. But in the Copper Spur example, vestibule area is reportedly 18 square feet.
What gives? Are they counting the whole piece of material that forms the floor, including the bit that wraps up the side of the tent to form the tub? Help! (And thanks…)
