Decomposed granite may be loose, stabilized, or resin-bound. Confirm density, compaction requirements, and stabilizer cost with your local supplier or installer.
How to calculate decomposed granite
Decomposed granite is estimated by volume first, then converted to tons for ordering. Measure the area, choose an installed depth, convert inches to feet, calculate cubic feet, divide by 27 for cubic yards, then multiply by tons per cubic yard.

Best uses for decomposed granite
Garden paths
Decomposed granite creates a natural-looking walking surface for garden paths and low-traffic walkways.
Patios
Compacted decomposed granite can be used for informal patio areas, seating zones, and outdoor living spaces.
Dog runs
DG is commonly used for dog runs and utility zones because it drains better than many bare soil surfaces.
Landscape areas
Use decomposed granite as decorative ground cover where a finer, more compacted surface is preferred.
Stabilized paths
Stabilized decomposed granite can reduce shifting and erosion on paths when installed correctly.
Low-maintenance yards
DG can help reduce mud, weeds, and maintenance in xeriscape and drought-tolerant landscapes.

Decomposed granite calculator FAQ
How do I calculate how much decomposed granite I need?
Multiply length by width to get square feet, multiply by depth in feet to get cubic feet, divide by 27 to get cubic yards, then add waste and convert to tons.
How deep should decomposed granite be?
Use about 2 inches for decorative cover, 3 inches for walkways, 3 to 4 inches for patios and dog runs, and deeper sections for compacted base systems.
How much does a cubic yard of decomposed granite weigh?
Decomposed granite commonly weighs about 1.3 to 1.5 tons per cubic yard, but supplier density can vary by moisture and compaction.
Should I use stabilized decomposed granite?
Stabilized decomposed granite can be useful for paths, patios, and areas where erosion or loose material movement is a concern.
