Deck Planning Tools is a free set of transparent estimators for homeowners, DIY planners, and construction professionals. The goal is to make early material and budget planning easier to understand—not to hide assumptions behind a single unexplained number.
Our approach
Calculators use typed, testable geometry and quantity functions. Inputs remain editable, calculation methods are documented, and structural tools stop at quantity estimation where a complete engineered design would be required.
What we do not claim
We do not provide live retailer prices, code approval, engineering services, or guaranteed takeoffs. Verify measurements, products, site conditions, and local requirements before purchasing or building.
