Density varies by material — loose gravel runs roughly 90–105 lb/ft³, compacted crushed stone can run higher. The default here (100 lb/ft³) is a typical mid-range value; adjust it to match your specific material's spec sheet for an accurate weight.

Enter the area, depth, and material density to calculate gravel volume and weight.

How to Use the Gravel Calculator

Area, depth, and material density — density varies noticeably by material, so check the specific gravel or aggregate being used rather than assuming a generic number.

cubic feet = length (ft) × width (ft) × (depth (in) ÷ 12)
weight = cubic feet × density (lb/ft³)

Volume's straightforward. Weight is where gravel gets messy, because density swings a fair amount by material — loose pea gravel sits lighter than compacted crushed stone, and this Gravel Calculator leaves density as an editable field rather than guessing, defaulting to 100 lb/ft³ as a reasonable middle-of-the-road estimate. Check your supplier's spec sheet for the actual material and swap the number in if precision matters.
