Gravel for 600 sq ft by depth

Depth	Cubic yards	Tons	Tons +10%
2 in	3.70	5.2	5.7
3 in	5.56	7.8	8.6
4 in	7.41	10.4	11.4
6 in	11.11	15.6	17.1

Working it out

600 sq ft × (4 ÷ 12) ft = 200.0 cubic feet.
÷ 27 = 7.41 cubic yards.
× 1.4 tons per yard = 10.4 tons.

About gravel

Because ’gravel’ covers so many products, the weight per yard moves with stone size and how much fine material is in the pile. Rounded stone with no fines rolls under tires; crushed stone with fines locks together. Expect the weight to fall in the range of 1.3 to 1.5 tons per yard.

Getting the order right

Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
Add a margin. About 10 percent covers compaction and low spots.
Bulk or bags. Bulk delivery is the practical choice here.
Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.

Use the volume and tonnage calculator for any other size.

Where gravel fits

Good uses:

Rural driveways and lanes where low upfront cost matters
Drainage areas and around downspouts
Temporary access while a site is under construction

Less suited to:

Steep slopes, where loose stone washes downhill
Spots plowed often, since plows push gravel into the lawn
Areas next to doors, because stone tracks inside

Quick reference numbers

Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
Per inch over 1,000 sq ft: about 4.3 tons.
Another size for comparison: a 12x24 area at 2 inches takes about 2.5 tons.
Weight used here: about 1.4 tons per cubic yard.

Common estimating mistakes

Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
