What are you building?

Grouped by the job, not by the tool name. Every calculator returns quantities you can actually buy.

Inside

Paint, primer and wall area for any room.

Area, waste and boxes for laminate, vinyl or wood.

Tiles, boxes and waste for floors or walls.

Sheets, screws and joint compound.

Volume, bags and mix for slabs and footings.

Posts, rails and pickets for any run.

Boards, joists and fixings for a deck.

Roof area, squares and shingle bundles.

Mulch, soil or gravel by volume and bags.

Area, perimeter and wall area for a room.

The calculator system is config-driven, so these categories expand without rebuilding the app.
