How much gravel for 12x24?
12 × 24 ft is 288 square feet. At 4 inches deep that is 96 cubic feet, or 3.56 cubic yards before waste. With 10% extra, order about 3.91 cubic yards, which is 5.5 US tons (5 metric tonnes) of pea gravel at 1.4 tons per yard.
By depth
At 2 inches, for a decorative bed or path, you need 1.96 cubic yards (2.8 tons). At 4 inches, for a patio or shed base, 3.91 cubic yards. At 6 inches, for a driveway, 5.87 cubic yards (8.3 tons). Crushed base you will compact is heavier and needs 10 to 15% more.
Bags or bulk?
A 0.5 cubic foot bag holds about 50 lb of pea gravel. At 4 inches this area would take about 212 bags, so bulk delivery by the ton is usually cheaper above about half a cubic yard.
