Find how many cubic yards of mulch, soil, gravel, or any material you need to cover an area — a yards-of-material calculator with cubic yard coverage built in.
Estimate only — order 5-10% extra to cover settling and an uneven base.
We multiply length × width × depth to get cubic feet, converting your depth from inches to feet first, then divide by 27 — the number of cubic feet in a cubic yard (3 ft × 3 ft × 3 ft). As a rule of thumb that falls out of the same math, one cubic yard covers about 100 sq ft at 3 in deep, 162 sq ft at 2 in deep, or 324 sq ft at 1 in deep.
Cubic yards are the standard unit bulk material suppliers price and deliver by — mulch, soil, and gravel are typically sold and hauled by the yard rather than the bag, since that's how a load is measured and billed. Working backward from a target depth, rather than eyeballing a pile size, is the more reliable way to order enough material without guessing, since a shallow miscalculation on a large area adds up fast.
It depends on depth: at 3 inches deep, 1 cubic yard covers about 100 sq ft. Enter your area and depth above for an exact number.
27 cubic feet make one cubic yard (3 ft × 3 ft × 3 ft).
Yes — the volume math is the same regardless of material. For gravel with a bag size and cost estimate, try the gravel calculator.
