Cheap lumber, simple cuts, and a result you’ll actually use — the 2x4 bench is the project everyone should start with. The cut list below is the real board breakdown from the 3D model, optimized so you buy as few boards as possible.
Need it longer for an entryway or shorter for the end of a bed? Drag the length in the editor. The build check confirms the seat won’t sag, and the shopping list shows exactly what to grab at the store and what it’ll cost.

How to build it
- Gather your lumber and hardware. Pick up the boards and fasteners from the shopping list. It’s optimized to minimize offcuts, so buy the counts shown.
- Cut your pieces. Cut each piece to the lengths in the cut list. The app can print a per-piece cut diagram for every board.
- Dry-fit and assemble. Lay the pieces out on a flat surface, check for square, then fasten them with the hardware listed.
- Check it holds, then finish. Confirm the design passes the build checks (sag, fasteners), then sand and finish to taste.
