Estimating the quantity of interior doors required for a project can be simplified with the use of a calculator. Below, you’ll find a tool to assist with this calculation based on door dimensions and the total area to be covered.

Example Calculation

Let's say you have doors with the following dimensions:

• Width: 36 inches
• Height: 80 inches
• Number of doors: 10

And you need to cover a total area of 300 square feet. Here’s how you would calculate the quantity:

1. Convert door dimensions from inches to feet:
• Width: 36 inches / 12 = 3 feet
• Height: 80 inches / 12 = 6.67 feet
2. Calculate the area of one door:
• Door Area = 3 feet * 6.67 feet = 20 square feet
3. Calculate the total door area:
• Total Door Area = 20 square feet * 10 doors = 200 square feet
4. Calculate the quantity required to cover 300 square feet:
• Required Quantity = 300 square feet / 200 square feet ≈ 1.5 doors

You would need approximately 2 doors to cover the 300 square feet area.
