Volume basics
A 3 × 3 × 3 ft cube, and how far it spreads at different depths.
Measuring your space
Rectangles, circles, tree rings and irregular beds split into shapes.
Volume & weight
Density, moisture and loose versus compacted material.
Buying & delivery
Quoted units, minimums, increments, delivery and questions to ask.
Step by step
Record the area and the depth of material you need.
How to Measure Landscape BedsConvert your measurements into cubic yards or another volume unit.
Square Feet to Cubic YardsUse your supplier’s density when converting volume to weight.
Cubic Yards to TonsConfirm whole bags, bulk minimums, increments and delivery costs.
Bulk vs Bags CalculatorRules worth knowing
Standard conversion
1 yd³ = 27 ft³
A cube 3 ft on each side, about 0.7646 m³.
Three dimensions
Area needs depth
Square feet alone cannot become cubic yards without a thickness.
Weight
Weight needs density
A cubic yard has no single weight — use your supplier’s density.
1 yd³ at 2 in deep
162 sq ft
1 yd³ at 3 in deep
108 sq ft
1 yd³ at 4 in deep
81 sq ft
