How Much Does 7 Tons of Gravel Cover?
How much does 7 tons of gravel cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 7 tons is roughly 5.0 cubic yards. Spread 4 inches deep, that covers about 405 square feet. Go thinner and it covers more; go deeper and it covers less.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 7 ÷ 1.4 = 5.0 yd³.
- Cubic yards to cubic feet: × 27 = 135 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 135 ÷ 0.333 = 405 sq ft.
Coverage of 7 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 810 | 90 |
| 3 in | 540 | 60 |
| 4 in | 405 | 45 |
| 6 in | 270 | 30 |
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. Weight runs about 1.3 to 1.5 tons per cubic yard, so treat the table as a planning range rather than an exact figure.
Putting 7 tons to use
For delivery, 7 tons usually fits on one smaller dump truck. Ask the supplier how they will split it. Spread from the pile with a loader, skid steer or wheelbarrow, then rake to depth before compacting if the material calls for it.
- Check depth as you go. Stakes marked at the target depth help keep the spread even.
- Expect some loss. Compaction and uneven ground use more than the flat-math figure. Keep about 10 percent in reserve.
- Ask about moisture. Wet material weighs more, so a ton of it covers less.
To run your own numbers, use the volume and tonnage calculator.
Good and poor uses for gravel
Best suited to:
- Rural driveways and lanes where low upfront cost matters
- Drainage areas and around downspouts
- Temporary access while a site is under construction
Poor fit for:
- 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 20x25 area at 3 inches takes about 6.5 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
