12x20 Deck Layout
A 12x20 deck gives you enough room for a full outdoor dining setup and a separate lounge area, and getting the joist and handrail details right up front keeps the build on track. ArcSite's 12x20 deck layout template lays out that framing for you, ready to adjust to your own footings.

Key Considerations When Designing a 12x20 Deck
Handrail integration and joist spacing carry both the structural load and the safety requirements on a 12x20 deck, so those details matter more than the finish work on top. In ArcSite, you can adjust this deck layout's joist placement and handrail detail to match your own site and local code.
