Thanks for your very interesting comments. Length: I thought Jardine's formula was reasonable. For me that is 68' + 36" = 104'. It may suggest more length than is needed for mild conditions, but for an extra 8" (experience tells me 96 inches as a minimum) is well worth the weight. As for width: Jardine's 86 inch recommendation (7.17 feet) seems reasonable. Pitched with a 90 degree peak that would make the triangle looking at the front of the "tent" 43" on two sides and a whole 60" across the bottom (if I remember my Pythagorean theorem correctly and my math didn't falter). So my conclusion is 104" x 86" and that is 7.17' x 8.67' would make a very nice solo A-Frame configuration. Interestingly enough that area (62.2 SF) is roughly the same as the 8' x 8' tarp (64 SF). The only advantage I might see in the 8x8 square is that it would set up nicely as a flying wedge. So perhaps 8x8 would win on flexibility, but the 7.17 x 8.67 would be better in the A-frame set up in a storm.
