Tiny home framing calculator

See the tiny home frame before you count the lumber

Use the framing calculator to set footprint, spacing, knee walls, rafter size, overhangs, porch inset, loft and openings. The model and estimate update together.

Open the framing builder

Stock-length planning

The estimator favors common board lengths up to 16 feet and identifies where long built-up beams require supported, staggered splices.

Opening framing

Door and window rough openings affect stud counts and add preliminary headers, king studs, jack studs and sills.

Hardware allowances

Hangers, rated connector fasteners, rafter ties and preliminary pier-to-beam connectors appear as their own line items.

Follow the load path from floor platform to roof

The 3D framing view lets you inspect piers, built-up beams, flush-hung floor joists, face-mount hangers, wall framing, rafters and loft members as one assembly. When a joist size changes, the preliminary beam rule keeps the beam at least as deep visually so the floor does not show impossible members hanging below a shallower support.

Openings and roof geometry change the framing count

Doors and windows add rough-opening framing such as king studs, jack studs, headers, sills and cripples where the modeled wall system uses them. A-frame and shed-roof geometry also affects rafter lengths and end cuts. Review those relationships in the blueprint and cut-sheet generator, then use the material calculator for quantities.

This is a construction-minded planning calculator, not structural engineering. Span, species, grade, snow and wind loads, bearing, uplift and connector schedules must be verified for the actual project.

Member sizes and connectors are preliminary. Final selection requires local loads, spans, species, grade and connection design.
