You need 14 squares of vinyl siding (175 panels).

  • You need 14 squares (175 panels) covering 1,399 sq ft of material area, which includes the 10% waste allowance.
  • Doors and windows account for roughly 168 sq ft of subtracted area. Material is still ordered for the full gross wall, so the offcuts can be used elsewhere.
  • The all-in estimate works out to about $3.98 per sq ft of installed siding at the prices you entered.
  • Add 15-20% waste for walls with lots of angles, diagonal courses, or decorative features; stick with 10% for flat, rectangular walls.

Next stepConfirm panel and trim quantities with your supplier before ordering. Ask about bulk pricing when buying more than 20 squares.
