Construction and Home Improvement Calculators

Estimate the materials for a home improvement or building job before you buy them: concrete, paint, flooring, tile, roofing, fencing, insulation and wallpaper. Enter your measurements and each calculator shows how much you are likely to need.

Results are estimates. Real jobs need extra for waste, cuts and uneven surfaces, so confirm quantities with your supplier or contractor and check local building rules before you order or build.
