DIY Calculator - Construction and material calculators
DIY Calculator helps homeowners work out exactly how much material to buy for a project. There are 22 calculators for gravel, mulch, topsoil, sand, crushed stone, paver base, concrete, asphalt, square footage, tile, pavers, sod, cinder block, brick and board feet. Enter measurements in feet, inches, yards or meters — split odd shapes into rectangles, circles and triangles — and see cubic yards, tons, bag counts and an optional cost estimate update as you type, next to a diagram of what you measured. Every result shows its formula and the material density it assumes, which you can change for your supplier. Everything runs in the browser.
