What this landscaping gravel calculator calculates
A 12 × 20 ft landscape area at 3 in depth contains 60 ft³, or 2.22 yd³, before waste. Density converts volume into a planning weight.
Formula
Length × width × depth ÷ 12 = cubic feet; cubic feet ÷ 27 = cubic yards; yards × density = pounds.
Worked example
At 10% waste, that 12 × 20 × 3 in area becomes 2.44 yd³. Using the 2,800 lb/yd³ gravel planning density gives about 6,845 lb.
Ordering decision
Moisture and gradation change delivered weight. Ask the supplier whether tons are sold by certified scale weight or estimated volume.

Landscaping gravel, not aquarium gravel
This construction gravel calculator is for landscaping beds, paths, and bases. It estimates volume and delivered weight from area, compacted depth, density, and waste, and it does not target aquarium fill.
Limits and professional review
Measurements, product yield, waste, moisture, and site conditions can change the order quantity. Local code and a licensed professional govern structural and electrical work.
