How Much Does 16 Tons of Pea Gravel Cover?
How much does 16 tons of pea gravel cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 16 tons is roughly 11.4 cubic yards. Spread 3 inches deep, that covers about 1,234 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 16 ÷ 1.4 = 11.4 yd³.
- Cubic yards to cubic feet: × 27 = 309 cu ft.
- Divide by depth in feet: at 3 inches (0.250 ft), 309 ÷ 0.250 = 1,234 sq ft.
Coverage of 16 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 1,851 | 206 |
| 3 in | 1,234 | 137 |
| 4 in | 926 | 103 |
About pea gravel
Pea gravel is small, rounded stone, usually around 3/8 inch. It is comfortable to walk on and drains well, but it shifts under car tires and needs a solid edge to stay put. 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 16 tons to use
16 tons is about one tandem-axle truck load, though legal limits vary by truck and state. 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 pea gravel
Good uses:
- Patios, walkways and dog runs
- Play areas with proper depth and edging
- Drainage around foundations when sized properly
Less suited to:
- Driveways and steep paths, where it rolls and ruts
- Under pavers as a base
- Areas without edging
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of pea gravel (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 15x30 area at 2 inches takes about 3.9 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
