How Much Gravel for a 6x15 Walkway?
A 6 by 15 foot walkway is 90 square feet. How much gravel for a 6x15 walkway depends on depth: at 3 inches it is about 0.83 cubic yards or 1.2 tons. Suppliers usually sell by the ton, so the tonnage is the number to give them.
Volume and tonnage calculator →The math for a 6x15 walkway
- Area: 6 × 15 = 90 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 90 × 0.250 = 22.5 cu ft.
- Cubic yards: ÷ 27 = 0.83 yd³.
- Tons: × 1.4 = 1.2 tons.
The volume and tonnage calculator does this for any size.
Gravel needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 0.56 | 0.8 | 0.9 |
| 3 in | 0.83 | 1.2 | 1.3 |
| 4 in | 1.11 | 1.6 | 1.7 |
| 6 in | 1.67 | 2.3 | 2.6 |
About gravel
Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. 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. Since the walkway carries foot traffic, 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. 1.3 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 1.2 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 walkway as firm ground allows.
Good and poor uses for gravel
Works well for:
- Rural driveways and lanes where low upfront cost matters
- Drainage areas and around downspouts
- Temporary access while a site is under construction
Less suited to:
- Steep slopes, where loose stone washes downhill
- Spots plowed often, since plows push gravel into the lawn
- Areas next to doors, because stone tracks inside
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 20x25 area at 3 inches takes about 6.5 tons.
- Weight used here: about 1.4 tons per cubic yard.
Common estimating mistakes
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
