Pavers: 560
Base rock: 3.7 cu yd (6 in. Density 2,700 lb/yd³ (TRORC crushed stone).)
Bedding sand: 0.62 cu yd (1 in. Dry sand at 97 lb/cu ft (Engineering ToolBox).)

Two hundred square feet of 6 by 9 pavers is 200 ÷ 0.375 = 533 before waste. Five percent is 560, and you buy 560. Six inches of base on that patio is about 3.70 yards of stone. One inch of sand is about 0.62 yards. More on sand and gravel if you want tons instead of yards.

FAQ

How many pavers?

Divide the patio by the face of one paver, then add the cut allowance. A 6 by 9 inch paver is 0.375 square feet. Joints between concrete pavers are small. If you leave a wide joint, add it the way the tile page does, or buy a few extra.

How much base and sand?

Base is area times the depth of crushed stone. Bedding sand is area times the sand depth. The form starts at 6 inches of base and 1 inch of sand as a walkway planning start. A drive needs a thicker base. Use the section your supplier specifies.
