You need approximately 41.7 cu ft (1.54 cu yd) of compost.

  • Your 200 sq ft area needs about 41.7 cubic feet of compost at 2.50 inches deep.
  • That is roughly 42 standard 1-cubic-foot bags, weighing about 1667 lb total.
  • The recommended depth range for "Garden bed (annuals/veg)" is 2 to 3 inches. This calculator used the midpoint (2.50 in).
  • Bulk compost from a landscape supplier is usually cheaper per cubic yard than bagged. Compare prices before ordering large quantities.

Next stepWork compost into the top 6-8 inches of soil for new beds, or leave it on the surface for established lawns. Water lightly after application to settle it.
