We know that getting your square footage can be an overwhelming task, so we wanted to provide some guidance for the best way to get accurate measurements.

Did you know that square footage is the number one way to predict the cost of your deck? The overall size has a greater impact than any other feature of your deck!

Here are some helpful methods to calculate your square footage. Knowing accurate square footage means that you're more likely to get a better estimate the first time!

Keep in mind that the base equation is the length of your deck multiplied by the width of your deck.

What if my deck is not a perfect rectangle?

No problem at all! Below we will describe different deck scenarios and explain methods to calculate the square footage of each.

What will I need to get started?

- Tape measure

- Calculator

- Notepad and pen/pencil/cell phone (or something else to record your measurements!)

Next, follow the steps that apply to your deck layout.

You multiply the length of the deck by the width of the deck. We will use a deck that is 10 ft x 15 ft as an example in all of our deck scenarios:

This is the equation: Length (ft) x Width (ft) = Square Footage

Example

10 ft x 15 ft = 150 sq. ft

Do you have niches, kitchen area, or storage in the deck area and want to install decking there as well?

Here is how to measure and calculate total square footage of the deck plus niches.

Split the deck into separate areas

In the diagram below they're listed as "Deck", "Nook 1", and "Nook 2"

Measure each area of the deck separately

Calculate the square footage of the each space by multiplying length by width.

Deck: Length (ft) x Width (ft) = deck SQFT (Square Footage)

Closet# 1: Length (ft) x Width (ft) = Closet #1 SQFT

Closet# 2: Length (ft) x Width (ft) = Closet #2 SQFT

Add the calculations of each space to equal a total square footage.

Formula: Deck SQFT + Nook #1 SQFT + Nook #2 SQFT = Total square footage of the deck

Based on our experience, people who have trouble figuring out the square footage of a complex space try to measure the entire space all at once. It is common to deal with a deck that has an open floor plan with several storage areas, nooks, built-in kitchens, or odd-shaped spaces.

The solution, however, is simple! All you need to do is to divide your space into even shapes, (squares or rectangles) and be able to use a calculation formula of length multiplied by width. After you are done with this step, the only thing to do is to add all individual spaces you just calculated together.

Separate the deck into squares or rectangles In the diagram. Below they're listed as Area 1, Area 2, and Area 3

Measure each rectangle or square area separately.

Calculate the square footage of the each space by multiplying length by width.

Area 1: A (length) x B (width) = Area 1 SQFT

Area 2: A (length) x B (width) = Area 2 SQFT

Area 3: A (length) x B (width) = Area 3 SQFT

Add the calculations of each space to equal a total square footage.

Formula: Area 1 SQFT + Area 2 SQFT + Area 3 SQFT = Total square footage of the deck
