How Much Pea Gravel for a 8x10 Patio?
How much pea gravel for a 8x10 patio: at 3 inches deep you need about 0.74 cubic yards, which is roughly 1.0 tons at 1.4 tons per yard. The patio covers 80 square feet, so every inch of depth adds about 0.25 yards.
Volume and tonnage calculator →The math for a 8x10 patio
- Area: 8 × 10 = 80 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 80 × 0.250 = 20.0 cu ft.
- Cubic yards: ÷ 27 = 0.74 yd³.
- Tons: × 1.4 = 1.0 tons.
The volume and tonnage calculator does this for any size.
Pea gravel needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 0.49 | 0.7 | 0.8 |
| 3 in | 0.74 | 1.0 | 1.1 |
| 4 in | 0.99 | 1.4 | 1.5 |
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. If the yard sells by the cubic yard instead of the ton, use the cubic-yard column directly.
Preparing the patio
Remove sod, level the area with a slight slope away from the house, and lay landscape fabric if weeds are a concern. Edging keeps loose material inside the patio footprint. Since the patio carries foot traffic and furniture, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 1.1 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At about 1.0 tons this job is small enough that bagged material could work; a 0.5 cubic foot bag holds about 1/54 of a yard, so compare the bag count with a bulk minimum.
- Where it drops. Have the truck dump as close to the patio as firm ground allows.
When to choose pea gravel
Works well for:
- 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 10x20 area at 2 inches takes about 1.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- 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.
- 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.
