How it is calculated
Volume = length × width × depth, plus the extra percentage. One cubic yard is 27 cubic feet.
Weight = volume × weight per cubic yard. Typical figures: about 1.4 tons per yd³ for gravel, 1.35 for sand and 1.1 for topsoil.
Worked example
With the starting values shown in the form, the result is 1.94 yd³ (you need). Change any number and the estimate updates as you type.
Tips
- Bulk delivery is priced per cubic yard or per ton; bags make sense for small beds.
- Lay landscape fabric under gravel paths so the stone doesn't sink into the soil.
Questions
- How many bags of mulch are in a cubic yard?
- 13.5 bags of 2 ft³, because a cubic yard is 27 ft³.
- How much does a cubic yard of gravel weigh?
