To measure your home for siding: measure each wall (height × width), calculate gable areas, add all sections, subtract windows and doors, add 10–15% for waste, and divide by 100 to convert to squares.
A square of siding equals 100 square feet of coverage. A typical 2,000 sq ft home needs 15–22 squares of siding material.

| Small Ranch (1,200 sqft floor) | 900–1,200 sqft | 10–13 |
| Average Ranch (1,800 sqft floor) | 1,200–1,600 sqft | 13–18 |
| Two-Story Colonial (2,400 sqft floor) | 1,800–2,400 sqft | 20–26 |
| Large Two-Story (3,000+ sqft floor) | 2,300–3,000 sqft | 25–33 |
