Key Features
This 14x20 deck layout includes:
- A true 14 by 20 foot footprint, already framed and dimensioned
- An 8-foot bay plus two 6-foot bays across the depth
- A 24-inch on-center callout on every joist
- A labeled arrow marking the house tie-in point
- Adjustable bay splits and spacing
The arrow marking the house tie-in lines up exactly where the plan calls it out, worth confirming against your own ledger before you frame the first bay.

Key Considerations When Designing a 14x20 Deck Layout
Three even bays across a 20-foot depth would land at an awkward 6-foot-8-inch split, which is why this plan uses one 8-foot bay plus two 6-foot bays instead, keeping every board length a standard cut. ArcSite lets you re-split those bays if your lumber supplier's stock lengths run differently than what's assumed here.
