How to Measure for Your New Deck

By Brian Wey, Project Developer

Measuring your deck space might sound simple—but doing it right makes all the difference between a rough estimate and an accurate, money-saving quote. All you need is a tape measure, a notepad, a pencil, and maybe a camera. Slowing down to get precise numbers is worth it. Decks can cost as much as a new car, so why leave the details to chance?

There’s no “standard” size deck anymore. Phrases like “about this high” or “I can walk under it” don’t give us the detail needed to plan and price your project properly. Exact measurements let us design a deck that fits your home perfectly, avoids costly changes later, and speeds up the building process.

7 Essential Measurements for Your Deck Estimate

(Don’t forget to bring a picture!)

1. Ground to Bottom of Door Sill – Tells us how high the deck surface needs to be.

2. Door Sill to Top of Door – Overall door height helps us plan railing clearance.

3. Top of Door to Soffit – Ensures room for rooflines, overhangs, or pergolas.

4. Ground to Soffit – Helps determine post and beam lengths.

5. Top of Window to Soffit – Avoids window trim interference.

6. Spacing Between Corners, Walls, Doors, and Windows – Critical for placing stairs or features.

7. Corner to Corner of House – Gives us the full layout for accurate design.

Pro Tip: Measurements are listed width (along the house) × projection (out from the house). For example, a 16’ × 12’ deck means 16 feet wide against the house and 12 feet projecting outward.

Pictures: Your Secret Weapon

Photos are just as important as measurements. Stand mid-yard and snap a straight-on view of your space. Then take angled shots from both sides. These images let us spot vents, outlets, AC units, or panels that might affect your deck’s design. A small detail in a photo can save you from costly changes during construction.

Why Accuracy Saves You Money

Taking a few extra minutes for detailed measurements prevents mid-project changes and unnecessary labor costs. It also ensures your design matches your vision from the start.
