How Much Does 15 Tons of Pea Gravel Cover?
How much does 15 tons of pea gravel cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 15 tons is roughly 10.7 cubic yards. Spread 3 inches deep, that covers about 1,157 square feet. Halve the depth and you roughly double the area.
Volume and tonnage calculator →How the coverage is figured
- Tons to cubic yards: 15 ÷ 1.4 = 10.7 yd³.
- Cubic yards to cubic feet: × 27 = 289 cu ft.
- Divide by depth in feet: at 3 inches (0.250 ft), 289 ÷ 0.250 = 1,157 sq ft.
Coverage of 15 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 1,736 | 193 |
| 3 in | 1,157 | 129 |
| 4 in | 868 | 96 |
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.
Planning around 15 tons
For delivery, 15 tons is in the range of one full tandem load. 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.
Where pea gravel fits
Good uses:
- Patios, walkways and dog runs
- Play areas with proper depth and edging
- Drainage around foundations when sized properly
Think twice for:
- 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 20x25 area at 2 inches takes about 4.3 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
