How Much Does 27 Tons of Gravel Cover?
How much does 27 tons of gravel cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 27 tons is roughly 19.3 cubic yards. Spread 4 inches deep, that covers about 1,562 square feet. Every added inch of depth cuts the coverage noticeably.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 27 ÷ 1.4 = 19.3 yd³.
- Cubic yards to cubic feet: × 27 = 521 cu ft.
- Divide by depth in feet: at 4 inches (0.333 ft), 521 ÷ 0.333 = 1,562 sq ft.
Coverage of 27 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 3,124 | 347 |
| 3 in | 2,083 | 231 |
| 4 in | 1,562 | 174 |

About gravel
Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. 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 27 tons to use
For delivery, 27 tons means multiple trips or a larger 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.
When to choose gravel
Works well for:
- 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 15x30 area at 4 inches takes about 7.8 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
