Formula used
Cover width = half-ellipse arc approximation + two side overlaps; cover area = cover width × house length
Worked hoop house example
Hoop House Calculator example: The half-ellipse arc for a 17.1-ft span and 8.54-ft peak is approximately 26.84 ft. Adding 2 ft at each side gives 30.84 ft of cover width; over a 23-ft house length, cover area is 709.43 ft².
What the converted result represents
Use cover width and area to choose a sheet size with adequate attachment margin, then calculate end-wall film separately.
Limits of the geometric model
Real bows may be circular, gothic, segmented, or flattened; end walls, roll-up sides, hems, fastening, shrinkage, and sheet stock sizes add material.
Questions specific to this calculation
What cross-section does the hoop-house estimate assume?
Enter house width, length, peak height, and cover overlap at each side. The cross-section is approximated as a half ellipse for cover arc length.
