Common questions

How much gravel do I need?

Multiply the length and width in feet by the depth in inches, divide by 12 to get cubic feet, then divide by 27 to get cubic yards. A 10 by 10 foot area 4 inches deep needs 1.23 cubic yards, about 1.7 tons of gravel.

How many tons is a cubic yard of gravel?

Usually about 1.3 to 1.5 tons, depending on the stone and how wet it is. The calculator starts at 2,800 pounds, 1.4 tons; use your supplier's figure if they quote one.

How many bags of gravel make a cubic yard?

A cubic yard is 27 cubic feet, so it takes 54 bags of 0.5 cubic feet, the usual size for bagged gravel and sand.

How many square feet does a yard of gravel cover?

At 2 inches deep, about 162 square feet; at 3 inches, 108; at 4 inches, 81; and at 6 inches, 54.

How deep should gravel be?

Paths and patios usually take 2 to 4 inches, and a driveway 4 to 6 inches over a compacted base. Pea gravel is usually laid 2 to 3 inches deep.

Should I order extra gravel?

Many people add 5 to 10 percent, because gravel settles and compacts and edges are never exact. Type it in the Extra box.
