DeckFrame app icon DeckFrame

Size your whole deck and print a code-cited plan.

DeckFrame sizes deck joists, beams, posts, footings, ledgers, and guards to DCA6 and IRC, then exports a code-cited PDF plan package for review. Offline. Free download with Pro unlock.

Load Path

One project model cascades through joists, beams, posts, footings, ledger fasteners, and guard checks.

Plan Review

The Pro export builds a PDF plan package with member schedules, citations, footing notes, ledger detail, and BOM.

Field Use

The app works offline and fails closed to engineer required when a condition falls outside the bundled prescriptive rows.

Deck Code FAQ

How far can a 2x10 deck joist span?

A Southern Pine No.2 2x10 at 16" o.c. spans about 14'-0" at 40 psf live load and L/360 per DCA6 Table 2; DeckFrame solves it for your species and spacing.

How big a footing for a deck?

Footing area equals tributary load divided by soil bearing. On 1500 psf a typical post needs an 18"-20" diameter footing, sized in DeckFrame.

How far apart do deck ledger lag screws go?

Spacing tightens as joist span grows. DeckFrame prints the bundled IRC R507.9.1.3 spacing row when the project matches a supported table condition.
