The Surface Area of a Greenhouse (gabled roof) calculator computes the exterior surface area of a greenhouse based on simple measurements. Gabled Roof Structure
INSTRUCTIONS: Choose units and enter the following:
Greenhouse Surface Area (SA): The calculator returns the surface area in square feet. However this can be automatically converted into other area units via the pull-down menu.
The surface area calculation is a simple computation using the sum of the surface area components:
Note: The formula above is accurate whether the greenhouse has even gables (isosceles triangle) or uneven gables as in the second diagram. Both gable areas are triangles with a surface area of base times height. In the latter case, the base is the sum of the two widths (W = W1 + W2)
