Cubic Yards from Length, Width, and Depth

Enter length L, width W, and height or depth H in feet. Volume V(ft³) = L × W × H; V(yd³) = V(ft³) ÷ 27. Both outputs are rounded to two decimals. This form does not estimate mass or price.

For a 9 ft × 6 ft × 1 ft rectangular bed, V = 54 ft³, and 54 ÷ 27 = 2.00 yd³ as displayed.

The result assumes straight sides and constant depth. Measure irregular sections separately and add their volumes. Compaction, spillage, and supplier delivery increments are not included.

Measure the depth that must exist after placement. A supplier may quote material loose in the truck while your project specifies a compacted layer; ask the supplier how those quantities relate for the actual material. The calculator does not convert between loose and compacted volume or round to a truck’s delivery increment. Recheck the smallest depth before ordering.
