Estimating Siding for a 900 Sq Ft House: How to Calculate the Right Amount of Siding Needed

When planning to side a 900 sq ft house, understanding how much siding you need is crucial to ensure a smooth renovation process. Siding not only enhances the aesthetics of your home but also protects it from the elements. The calculation depends on several factors, including the height of your walls, the type of siding you choose, and any architectural features of your home.

Calculating the Wall Area for Siding

To estimate the amount of siding required, first calculate the wall area. A typical 900 sq ft house might have an average wall height of 8 to 10 feet. For example, if your house has four walls, the total wall area can be calculated as follows: (2 x Width + 2 x Length) x Height. This gives you a rough estimate of the total square footage of siding required.

Considering Windows and Doors

Remember to subtract the area of windows and doors from your total wall area. On average, a window might take up about 15 sq ft, while a door could take around 20 sq ft. By factoring in these openings, you will arrive at a more accurate siding requirement.

Choosing the Right Siding Material

The type of siding you select also influences the amount needed. Different materials come in various sizes and coverage areas. For instance, vinyl siding typically comes in panels that cover about 25 sq ft each. Knowing this will help you determine how many panels to purchase.

Final Calculations and Tips

After calculating the wall area and subtracting for openings, add an extra 10% to account for waste and mistakes during installation. This extra allowance ensures you have enough material to complete the job without needing to make last-minute purchases.
