Ordering decomposed granite comes down to two numbers: the area you are covering and how deep you want it. This guide gives you the coverage per ton, a simple formula, and the extra you should add for compaction so you order the right amount the first time.
Quick answer: one ton of decomposed granite covers about 100 square feet at 2 inches deep. Add 10 to 15 percent for compaction. Call (818) 503-4242 with your square footage and we will size the order for you.
Decomposed granite coverage per ton
Coverage depends on depth. Deeper installs cover less area per ton. Here is what one ton covers at common depths:
| Depth | Coverage per ton | Best for |
|---|---|---|
| 1 inch | about 200 sq ft | top dressing an existing surface |
| 2 inches | about 100 sq ft | pathways, patios, ground cover |
| 3 inches | about 65 to 70 sq ft | high traffic paths, dog runs |
| 4 inches | about 50 sq ft | driveways over a base |
How to calculate how much DG you need
Use this simple formula:
Tons = (square feet divided by 100) times (depth in inches divided by 2)
Worked example: a 500 square foot pathway at 2 inches deep.
- 500 divided by 100 equals 5
- 2 inches divided by 2 equals 1
- 5 times 1 equals 5 tons
- Add 10 to 15 percent for compaction, so order about 5.5 tons

Bags or bulk?
A half cubic foot bag of decomposed granite covers about 3 square feet at 2 inches deep. Roughly 40 bags equal one ton. Bags make sense for small repairs and tight access. For anything larger, bulk by the ton is far cheaper per square foot and faster to load. Contractors pick up bulk DG same day at our yards, or we deliver across Los Angeles County.
How much extra to order for compaction
Decomposed granite settles once it is watered and tamped. Order about 10 to 15 percent more than your bare coverage number so you are not short at the end of the job. A little extra also lets you top off low spots after the first rain.
