How the math works
24 ft × 50 ft = 1,200 sq ft. At 3 inches deep that's 1,200 × 3 ÷ 12 = 300 cubic feet, and ÷ 27 = 11.11 cubic yards. Adding 10% gives 330 cubic feet to buy.
How deep should it be?
For a top-up on an existing gravel surface, 2 to 3 inches is common. New driveways and paver bases are built thicker, in compacted layers: Unilock's guide calls for 6 to 8 inches of base under patios and walkways and 10 to 14 inches under paver driveways.
