DIY & Home Calculators

Home improvement stores love it when you guess — because guessing usually means buying too much. Our DIY and home calculators give you exact material estimates for paint, flooring, tile, mulch, fencing, wallpaper, and every other common home project. Enter your room dimensions and get precise quantities with waste factors already included. Know exactly how many gallons of paint to buy, how many boxes of laminate flooring you need, or how many bags of mulch will cover your garden beds. Stop overpaying for leftover materials and stop making extra trips to the store mid-project.
