Key Features

This 16x20 deck layout includes

  • 2x8 joists spaced 16 inches on-center
  • 4x4 post and framing element labeling
  • Precise 16x20 footprint dimensions
  • Plan view of the full framing layout

The 2x8 joists at 16-inch spacing are sized for a standard load, worth double-checking against your local code if you're planning a hot tub or other heavy fixture on this deck.

Key Considerations When Designing a 16x20 Deck

A deck this size carries real load across a wide span, so joist size and on-center spacing matter more here than on a smaller deck. In ArcSite, you can adjust this 16x20 deck layout's joist placement and post framing to match your own site and local code.
