This tool will help you estimate the total cost and amount of siding needed for your house accurately.

### How to Use the House Siding Calculator

To use the house siding calculator, please follow these instructions:

- Enter the length of the house in feet into the “Length of House” field.
- Enter the width of the house in feet into the “Width of House” field.
- Enter the height of the house in feet into the “Height of House” field.
- Enter the number of windows in your house into the “Number of Windows” field.
- Enter the number of doors in your house into the “Number of Doors” field.
- Enter the coverage area of one unit of siding in square feet into the “Siding Coverage Area per Unit” field.
- Click the “Calculate” button to see the results.

### How It Calculates the Results

The calculator uses the input values to compute the total exterior wall area by using the formula:

Total Wall Area = 2 * (Length * Height + Width * Height) – (Windows Area + Doors Area)

Here, each window is assumed to have an area of 15 square feet, and each door is assumed to have an area of 21 square feet.

The required number of siding units is then calculated by dividing the total wall area by the coverage area of one unit of siding:

Required Siding Units = Total Wall Area / Siding Coverage Area per Unit

### Limitations

- The calculator assumes rectangular walls and standard window and door sizes.
- Siding coverage area per unit should be known and provided by the user.
- Complex shapes or additional architectural features are not accounted for in this simple calculation.

## Use Cases for This Calculator

### Determine Material Quantity

When planning to re-side your home, you first need to calculate the amount of siding material required. By entering the dimensions of your house, the calculator will help you determine how many square feet of siding you’ll need, which ensures you purchase enough material without overbuying.

### Estimate Total Costs

Knowing the quantity of siding material needed is just the start; you also need to budget for costs. By using the calculator, you can input material prices and receive an estimated total cost, allowing you to plan your finance accordingly without unexpected expenses.

### Choose Siding Type

Different types of siding materials come with varying costs and installation complexities. The calculator can help you evaluate the pros and cons of options like vinyl, wood, or fiber cement, aiding you in making an informed decision based on your budget and aesthetic preferences.

### Plan for Installation Labor

It’s essential to factor in labor costs when installing new siding. By specifying whether you plan to do it yourself or hire professionals, the calculator can provide insights into potential labor costs, helping you to budget more accurately for the entire project.

### Understand Energy Efficiency Benefits

New siding can significantly impact your home’s energy efficiency, leading to long-term savings on utility bills. The calculator can help you estimate potential energy savings based on different siding materials, making your investment decision more viable.

### Factor in Building Codes and Regulations

Your local building codes may require specific types or styles of siding. The calculator can prompt you to consider these requirements, ensuring your project remains compliant and avoids costly fines or rework down the line.

### Evaluate Return on Investment

### Compare DIY vs. Professional Installation

If you’re contemplating whether to tackle the siding project yourself, the calculator can help you weigh the costs of DIY against hiring professionals. By inputting material and labor costs, you can see the financial implications of both choices upfront.

### Track Project Progress

During the siding installation, tracking how much material you have left can be daunting. The calculator can serve as a useful tool to update and adjust your material needs based on how much siding you’ve already installed, keeping your project organized and on schedule.
