Roof Pitch Multiplier Chart & Calculator Guide
Use this interactive lookup table to calculate how roof slope increases flat 2D satellite surface area into true 3D roof square footage.
| Pitch (Rise / 12) | Slope Angle (Degrees) | Multiplier Factor | Area Increase (%) |
|---|---|---|---|
| Flat (0/12) | 0° | ×1.000 | +0.0% |
| 2/12 | 9.5° | ×1.014 | +1.4% |
| 3/12 | 14° | ×1.031 | +3.1% |
| 4/12 | 18.4° | ×1.054 | +5.4% |
| 5/12 | 22.6° | ×1.083 | +8.3% |
| 6/12 | 26.6° | ×1.118 | +11.8% |
| 7/12 | 30.3° | ×1.158 | +15.8% |
| 8/12 | 33.7° | ×1.202 | +20.2% |
| 9/12 | 36.9° | ×1.250 | +25.0% |
| 10/12 | 39.8° | ×1.302 | +30.2% |
| 11/12 | 42.5° | ×1.357 | +35.7% |
| 12/12 | 45° | ×1.414 | +41.4% |
Formula Used
True Roof Area = Flat Footprint Area × Pitch Multiplier
Multiply your 2D satellite footprint by the corresponding factor above to convert projected flat area into actual 3D sloped surface area.
