I'm 6'2" and i set the hoops at a hight that i can walk down the center without scraping any hair of off by head, I like to keep what little I have up there. The original dimensions are listed in the parts manual, there were a lot of different ones but most are rectangular like the drawing above.
you might notice my roof is flat as I added a roof onto of the hoops using 1/2 plywood with 1/4 across the crown to fold over the peak. I painted it all white with a mold and mildew resistant bathroom paint, then added a layer of the bubble insulation to provide some softness then a white plastic tarp over it all to provide a brighter interior. then some extra insulation as padding on the corners and the canvas overtop. My wife says it's my alternate accomadation should i not obtain forgiveness one of these times.
