Chris, just measure one side from the roof ridge and then down the side to the ground. Double that measurement and you have your longest length x 13'. Then you'll need enough for the two ends and that should be 8'x10' x 2. I lined my two sliding doors with the solar material but did so inside. I also have a piece of material that will cover the entire width of those two doors (about 6') and keep it rolled up over the doors. When cold weather get here, I can simply allow that material to unroll, draping the doors for further protection. My doors face the north, so it keeps that extra-cold north wind off those doors to some extent.
My material is translucent. One cannot see into the greenhouses with any clarity. These pictures are several years old but you can see how I use aluminum wire to hold the material down. In the spring I simply remove the wiring and the material comes down easily.

The reason it's so hard to lose weight when you get up in age is because your body and your fat have become good friends.
