How Much River Rock for a 5x60 Walkway?
How much river rock for a 5x60 walkway is a quick volume problem. 300 square feet at 3 inches comes to 2.78 cubic yards. River rock usually weighs about 1.25 to 1.45 tons per cubic yard, so plan on roughly 3.8 tons.
Volume and tonnage calculator →The math for a 5x60 walkway
- Area: 5 × 60 = 300 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 300 × 0.250 = 75.0 cu ft.
- Cubic yards: ÷ 27 = 2.78 yd³.
- Tons: × 1.35 = 3.8 tons.
The volume and tonnage calculator does this for any size.
River rock needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 1.85 | 2.5 | 2.8 |
| 3 in | 2.78 | 3.8 | 4.1 |
| 4 in | 3.70 | 5.0 | 5.5 |
About river rock
River rock is mostly decorative and for drainage beds. It is not meant to be driven on and tends to roll if used as a walking surface. Weight per yard is a planning number; the scale ticket at the yard is the real one.
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. This walkway sees foot traffic, so match the depth to that load rather than to the minimum.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 4.1 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 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.
Good and poor uses for river rock
Good uses:
- Dry creek beds and drainage swales
- Decorative borders and planting beds
- Around downspouts to stop splash erosion
Poor fit for:
- Walking surfaces
- Driveways
- Bases under slabs or pavers
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of river rock (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 20x25 area at 3 inches takes about 6.3 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- 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.
