Carport minimum dimensions
Enter the measurements above to calculate carport minimum dimensions.
How the calculation works
V9 calculation: minimumCarportWidth=vehicleWidth+2×sideOverhangProtection; minimumCarportLength=vehicleLength+2×frontRearOverhang; minimumClearHeight=vehicleHeight+heightClearance. The result is reported as carport minimum dimensions.
Worked example
Example: Vehicle length = 450 cm; Vehicle width = 185 cm; Vehicle height = 165 cm; Roof overhang protection each side = 30 cm; Roof overhang front/rear = 30 cm; Roof clearance = 5 cm. Result: Minimum Clear Height = 170 cm; Minimum Carport Length = 510 cm; Minimum Carport Width = 245 cm.
