Gravel calculator
Area in sq ft, depth in inches, density (1.4 tons/cu yd). Yards and tons. Waste optional.
CopiedAbout this gravel calculator
Length, width, and depth of a gravel bed to volume, then to tons or bags using a density factor the form states.
Volume in cubic yards from dimensions; weight ≈ volume × density (for example tons per cubic yard for crushed stone). Densities vary by material and moisture.
Not a compaction or drainage design. Order a little extra; suppliers measure differently than a perfect rectangular prism.
FAQ
How is this calculated? Cubic yards = area × (depth inches / 12) / 27. Tons = cubic yards × density (default 1.4). Waste multiplies volume first.
Why 1.4 tons per cubic yard? A common bulk gravel density. Wet or crushed stone can differ — change the density if your supplier says otherwise.
What is waste? A percent added on top of the raw volume.
