How Much Does 4 Tons of Pea Gravel Cover?
How much does 4 tons of pea gravel cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 4 tons is roughly 2.9 cubic yards. Spread 3 inches deep, that covers about 309 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: 4 ÷ 1.4 = 2.9 yd³.
- Cubic yards to cubic feet: × 27 = 77 cu ft.
- Divide by depth in feet: at 3 inches (0.250 ft), 77 ÷ 0.250 = 309 sq ft.
Coverage of 4 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 463 | 51 |
| 3 in | 309 | 34 |
| 4 in | 231 | 26 |
About pea gravel
Because pea gravel is round, it never fully locks. Keep depths modest on walkways and patios so it does not feel like walking on a beach, and use edging. 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 4 tons to use
For delivery, 4 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.
When to choose pea gravel
Best suited to:
- 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 10x20 area at 4 inches takes about 3.5 tons.
- Weight used here: about 1.4 tons per cubic yard.
Mistakes that throw off the order
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons 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.
