Greenhouse Plastic Size Calculator
Measure dimensions A, B, C, and D on your greenhouse.
Not sure how to measure C? You can use a 100' measuring tape or take a piece of rope, throw it over the side of the greenhouse, mark it at the base on each side, stretch the rope out on the ground when done, and measure the distance between the two markings on the rope.
NOTE: If you want to cover your greenhouse with a double layer of plastic film, you will need to purchase 2 of each size plastic listed above. You will also need an inflation blower and jumper hoses for each end wall if you do not have them already.
Example Calculation
Greenhouse Dimensions: A=14' | B=8' | C=16' | D=9'
Film size for top and sides: (A + 1') x (C + 1') or 15' x 17'
Result: You will need to order 15' of our 20' wide plastic.
Film size for end walls: (D + 1') x (B + 1') or 10' x (9' x 2 end walls) = 10' x 18'
Result: You will need to order 10' of our 20' wide plastic.
Price: $2.85 - $4.50 per foot
