Siding Calculator

Estimate siding squares from wall area, openings (width × height), and waste.
Use By wall when each side has its own length and height (typed fields, like Standard). Use Standard or Draw footprint when one perimeter and one wall height is enough.

Wall openings (optional)

Add each window, door, or garage opening as width × height (m × m). We subtract the total from gross wall area.
