Material List Calc
Choose a project calculator, enter the room or site dimensions, and turn the result into a material list before you buy. The most-used tools cover concrete bags, flooring boxes, paint gallons, tile, mulch, gravel, roofing, trim, drywall, and insulation.
If you know the product type, open that calculator first and enter the coverage printed on the bag, box, roll, shingle bundle, or paint can. Each estimate includes waste allowance and a shopping-list style result so the page answers more than simple area.
Each tool shows the math used for its estimate.
Results include a copyable material list, not only area.
Verify labels, site conditions, and local requirements.
