Key Considerations When Designing a 12x24 Deck

Customize & Download

Reinforced ledger board connections and mid-span bridging matter more on a deck this long, since the extra length puts more strain on the joists than a smaller square deck would. In ArcSite, you can adjust this 12x24 deck layout's joist spacing and bridging to match your own span and local code.
