How much pea gravel for a 6x40 walkway is a quick volume problem. 240 square feet at 3 inches comes to 2.22 cubic yards. Pea gravel usually weighs about 1.3 to 1.5 tons per cubic yard, so plan on roughly 3.1 tons.
Volume and tonnage calculator →The math for a 6x40 walkway
- Area: 6 × 40 = 240 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 240 × 0.250 = 60.0 cu ft.
- Cubic yards: ÷ 27 = 2.22 yd³.
- Tons: × 1.4 = 3.1 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 | 1.48 | 2.1 | 2.3 |
| 3 in | 2.22 | 3.1 | 3.4 |
| 4 in | 2.96 | 4.1 | 4.6 |
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 walkway
Dig the path a few inches below grade, compact the bottom, add fabric if needed and install edging on both sides so the material stays on the walk. For foot traffic, the depths in the table above are a reasonable starting range.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 3.4 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 this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the walkway as firm ground allows.
Where pea gravel fits
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 12x24 area at 3 inches takes about 3.7 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
