Depth is the lever
2–3 in is the standard bed depth; 4 in suppresses weeds but roughly doubles the material versus 2 in.

Mulch Calculator
Estimate how much mulch you need for a garden bed or landscaped area. Enter the area and depth, and this calculator returns the bulk volume in cubic yards and the number of 2-cubic-foot bags — with a settling overage you control.
Quick answer
A 200 sq ft bed at 3 in needs ~2.04 cu yd of mulch — about 28 × 2-cu-ft bags — including 10% overage.

Materials for the same job
Planning a full project? Most jobs use more than one material. You will often pair topsoil, sod and sand with mulch on the same site.
Interpret the output
What makes this move?
A trustworthy estimate explains the levers behind the number. These are the factors that change how much you need to order.
Bags vs bulk
Over about 2 cubic yards, bulk delivery beats hauling 27+ bags — and costs less per yard.
Settling
Fresh mulch settles, so a slight overage keeps full coverage through the season.
