Key Features
This 10x18 deck layout includes:
- A true 10 by 18 foot footprint at 180 square feet
- Three equal 6-foot framing bays across the 18-foot depth
- A 24-inch on-center callout on the framing plan
- An arrow marking the house attachment point
- Adjustable bay length and spacing
The 24-inch on-center callout stays visible right on the plan, a detail inspectors look for before they'll sign off on the framing.
Key Considerations When Designing a 10x18 Deck Layout
Running three 6-foot bays across an 18-foot depth keeps each span shorter than stretching two wider bays across the same footprint, which is part of why the on-center spacing holds at 24 inches instead of needing to tighten up. ArcSite lets you test a two-bay layout instead if you'd rather work with fewer, longer joists.

FAQ
The 24-inch on-center spacing is called out directly on the plan, which is the detail inspectors typically check for before signing off on framing.
Yes! ArcSite lets you edit the on-center callout and bay widths to match your local code.
Yes. Once the layout is finalized, ArcSite can generate a materials list and estimate based on what you've drawn.
