Three steps, one answer

Measure

Length and width in feet, plus depth where it applies. Round and known areas work too.

Pick your option

Bag size, paver size, or coverage - and add a price to estimate cost.

Get the answer

Cubic yards, bags, pieces, weight, and cost - with a waste allowance built in.

Numbers you can trust

Every result uses the real conversions the trade uses: 27 cubic feet per cubic yard, standard 2 cubic foot mulch bags, and verified Quikrete bag yields (an 80 lb bag makes 0.60 cubic feet). Where weight depends on the material, we show an honest range instead of false precision. See exactly how we calculate, or browse our project guides.
