Before starting a custom deck project, it helps to have a general idea of the size and layout you want. Knowing how to measure your backyard for a custom deck is an essential first step. While our Techwood Decks specialists will take precise measurements during your consultation, you can do a quick, easy estimate at home. This helps you visualize your space, share ideas, and get a ballpark budget range.
Step 1: Gather Your Tools
You don’t need anything fancy—just:
- A 25–30 ft measuring tape
- A notepad or graph paper
- A pen or pencil
- (Optional) Stakes and string to mark the outline on your lawn
Step 2: Choose Your Deck’s Location
Think about:
- Proximity to your home: Will it attach to your house or be freestanding? Knowing how to measure your backyard for a custom deck here is crucial.
- Sunlight & shade: Observe where the sun hits during the day.
- Views & privacy: Position the deck to capture the best scenery while maintaining comfort.
Step 3: Mark the Shape
Use stakes and string (or even a garden hose) to outline where your deck will go. This lets you:
- Walk around the footprint and imagine the space
- Check if it fits well with existing landscaping, ensuring you’ve learned how to measure your backyard for a custom deck properly.
- Make adjustments before measuring
Step 4: Measure the Length & Width
- Stretch the measuring tape along the longest side (length)
- Measure the shorter side (width)
- Write these numbers down in feet after you measure your backyard for a custom deck design.
Quick Tip: For irregular shapes, break the deck into rectangles or squares, measure each one separately, and add them together.
Step 5: Calculate the Rough Square Footage
Multiply length × width.
Example: 16′ × 20′ = 320 SQFT
This isn’t the final number we’ll build from—but it’s perfect for discussing budget ranges and material options.

Step 6: Take Note of Obstacles
Record anything that might affect design or construction, such as:
- Trees or landscaping you want to keep
- Slope in the yard, which you’ll consider when you measure your backyard for a custom deck.
- Utility lines or drainage areas
Step 7: Bring Your Notes to Your Consultation
When you meet with our team, these rough measurements will:
- Speed up the design conversation
- Help us recommend the best TimberTech materials and colors
- Allow us to prepare a more accurate estimate faster
