Free Home and DIY Calculators
5 Free Tools
Work out the materials for a home project before you go to the shop. Count the posts, pickets and concrete for a fence, the cubic yards or tonnes of gravel for a path or driveway, the concrete and premix bags for a slab, and the paint for a room. Every calculator works in feet and inches or metres and centimetres and shows the formula with a worked example. The results are estimates for planning, so check them against your plans and the products you buy.
