Understand the result
How this calculation works
Hip roof area is the sum of four already measured sloped planes.
Steps
- Measure each plane, enter each area once and submit.
- Do not enter footprint dimensions in these fields.
The form starts with the worked example below. Change its values and selections to match your task; Reset restores the example.
Formula
area = plane 1 + plane 2 + plane 3 + plane 4.
Variables and units
- Plane 1 (sq ft)
- Required. Use a positive value. Starting example: 500. Replace it for your task.
- Plane 2 (sq ft)
- Required. Use a positive value. Starting example: 500. Replace it for your task.
- Plane 3 (sq ft)
- Required. Use a positive value. Starting example: 350. Replace it for your task.
- Plane 4 (sq ft)
- Required. Use a positive value. Starting example: 350. Replace it for your task.
What the result means
The calculator adds measured surfaces; it does not infer hip geometry from a footprint.
Worked example
Inputs: Plane 1 = 500; Plane 2 = 500; Plane 3 = 350; Plane 4 = 350.
Calculation: 500 + 500 + 350 + 350 = 1,700 sq ft.
Result: 1,700 sq ft.
Frequently asked questions
Can I omit a plane?
No. Enter all four measured planes; use measured quantity totals for fewer planes.
Are these plan areas?
No, enter sloped surface areas.
Does it include waste?
No, use a material quantity page for waste.
