How Much Does 45 Tons of Pea Gravel Cover?
How much does 45 tons of pea gravel cover depends on how deep you spread it. At about 1.4 tons per cubic yard, 45 tons is roughly 32.1 cubic yards. Spread 3 inches deep, that covers about 3,471 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: 45 ÷ 1.4 = 32.1 yd³.
- Cubic yards to cubic feet: × 27 = 868 cu ft.
- Divide by depth in feet: at 3 inches (0.250 ft), 868 ÷ 0.250 = 3,471 sq ft.
Coverage of 45 tons at different depths
| Depth | Square feet covered | Square yards |
|---|---|---|
| 2 in | 5,207 | 579 |
| 3 in | 3,471 | 386 |
| 4 in | 2,604 | 289 |
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 45 tons to use
45 tons will usually take two or more truck loads, 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.
Good and poor uses for pea gravel
Works well for:
- 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.
Mistakes that throw off the order
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- 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.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
