BEFORE YOU BUY MATERIALS

A calculator is most useful when the measurements going in are clear. These are the three things worth checking before you buy.

Use the real length, width or wall dimensions of the project area instead of relying on room labels or rough guesses for precise measurements.

Cuts, breakage, touch-ups and offcuts can change what you need. Use a waste allowance that matches the material and project.

Paint cans, tile boxes, flooring cartons and concrete bags are sold in fixed sizes, so compare the estimate with the product label before purchasing.
