How Much Sand for a 5x15 Walkway?
How much sand for a 5x15 walkway is a quick volume problem. 75 square feet at 3 inches comes to 0.69 cubic yards. Sand usually weighs about 1.3 to 1.5 dry tons per cubic yard, so plan on roughly 0.9 tons.
Volume and tonnage calculator →The math for a 5x15 walkway
- Area: 5 × 15 = 75 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 75 × 0.250 = 18.8 cu ft.
- Cubic yards: ÷ 27 = 0.69 yd³.
- Tons: × 1.35 = 0.9 tons.
The volume and tonnage calculator does this for any size.
Sand needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.23 | 0.3 | 0.3 |
| 2 in | 0.46 | 0.6 | 0.7 |
| 3 in | 0.69 | 0.9 | 1.0 |
| 4 in | 0.93 | 1.2 | 1.4 |
About sand
Sand weight changes a lot with moisture. Damp sand can weigh noticeably more per yard than dry sand, so a ton of wet sand covers less area than the same ton dry. 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. 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. 1.0 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 0.9 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 sand
Good uses:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Less suited to:
- Driveway bases, since sand shifts under load
- Steep areas exposed to runoff
- Thick layers under pavers, which settle unevenly
Quick reference numbers
- Per inch over 100 sq ft: about 0.42 tons of sand (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.2 tons.
- Another size for comparison: a 8x16 area at 3 inches takes about 1.6 tons.
- Weight used here: about 1.35 tons per cubic yard.
Common estimating mistakes
- 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.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
