Siding not only enhances the curb appeal but also adds value to your home. Let’s dive into the specifics of calculating the siding needed for your 2000 sq ft two-story house.Understanding Siding RequirementsTo accurately calculate the siding amount, you first need to determine the total wall area of your home. This includes both the first and second stories. For a standard two-story rectangular home, the formula to calculate the wall area is: Wall Area = Perimeter x HeightCalculating the Perimeter and HeightFor a 2000 sq ft home, let’s assume an average width and depth of 40 feet and 50 feet respectively. The perimeter can be calculated as follows: Perimeter = 2 x (Width + Depth) = 2 x (40 + 50) = 180 feetNext, if we consider an average height of 20 feet for a two-story home, the total wall area can be computed: Total Wall Area = Perimeter x Height = 180 x 20 = 3600 sq ftDetermining the Amount of Siding NeededNow that you have the total wall area, you will need to subtract any areas that won't require siding, such as windows and doors. On average, windows and doors can take up about 15-20% of the wall area. Assuming a 20% deduction, the calculation would be: Adjusted Wall Area = Total Wall Area - (0.20 x Total Wall Area) = 3600 - 720 = 2880 sq ftThis means you would need approximately 2880 sq ft of siding. However, it’s always wise to purchase a little extra to account for cutting and wastage, so consider adding another 10% to your final estimate.ConclusionCalculating the amount of siding for a 2000 sq ft, two-story home involves understanding the total wall area, accounting for non-siding areas, and adding a safety margin for waste. This ensures you have enough material to complete your project without unnecessary delays.
