Coverage Guide

How much area 1 cubic yard covers at different depths:

DepthCoverage (sq ft)
1"324 sq ft

Formula Used

Volume = Length x Width x Depth

33.33 cu ft / 27 = 1.23 cubic yards

Recommended Depths by Use

Quick Answer

To calculate cubic yards: multiply Length x Width x Depth (all in feet), then divide by 27. Example: A 10x10 ft area, 4 inches deep = (10 x 10 x 0.33) / 27 = 1.22 cubic yards. Coverage: 1 cubic yard covers 324 sq ft at 1" depth, 162 sq ft at 2" depth, 108 sq ft at 3" depth, or 81 sq ft at 4" depth.

Key Facts

  • Formula: Cubic Yards = (Length x Width x Depth in feet) / 27
  • 1 cubic yard = 27 cubic feet = 46,656 cubic inches
  • 1 cubic yard covers 162 sq ft at 2" depth, 81 sq ft at 4" depth
  • Concrete: 45 80-lb bags = 1 cubic yard (~4,050 lbs)
  • Gravel: 1 cubic yard weighs ~2,700 lbs (1.35 tons)
  • Mulch: 1 cubic yard weighs ~400-800 lbs
  • Standard dump truck capacity: 10-14 cubic yards
  • Always order 5-15% extra for waste and compaction

Frequently Asked Questions

Multiply length x width x depth (all in feet), then divide by 27. For depths in inches, convert to feet first by dividing by 12. Example: A 20x30 ft patio, 4" deep = (20 x 30 x 0.33) / 27 = 7.33 cubic yards.
Coverage depends on depth: 1" depth = 324 sq ft, 2" depth = 162 sq ft, 3" depth = 108 sq ft, 4" depth = 81 sq ft, 6" depth = 54 sq ft. To find coverage: 324 / depth in inches = sq ft covered.
One cubic yard of concrete requires approximately 45 80-lb bags, 60 60-lb bags, or 90 40-lb bags. Each 80-lb bag yields about 0.6 cubic feet. For projects over 0.5 cubic yards, consider ordering ready-mix concrete.
Weight varies by material: Concrete = ~4,050 lbs (2 tons), Gravel = ~2,700 lbs (1.35 tons), Sand = ~2,700 lbs, Topsoil = ~2,000 lbs (1 ton), Mulch = ~400-800 lbs. Always check with your supplier.
Divide cubic feet by 27 to get cubic yards. There are 27 cubic feet in 1 cubic yard (3 ft x 3 ft x 3 ft = 27 cu ft). Example: 54 cubic feet / 27 = 2 cubic yards.
Yes, order 5-15% extra to account for waste, spillage, uneven ground, and compaction. For gravel and crushed stone, add 10% for compaction. For irregular shapes or sloped areas, add 15%. It's better to have a little extra than to run short.
