How Much Sand for a 6x15 Walkway?
How much sand for a 6x15 walkway is a quick volume problem. 90 square feet at 3 inches comes to 0.83 cubic yards. Sand usually weighs about 1.3 to 1.5 dry tons per cubic yard, so plan on roughly 1.1 tons.
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: × 1.35 = 1.1 tons.
The volume and tonnage calculator does this for any size.
Sand needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.28 | 0.4 | 0.4 |
| 2 in | 0.56 | 0.8 | 0.8 |
| 3 in | 0.83 | 1.1 | 1.2 |
| 4 in | 1.11 | 1.5 | 1.7 |
About sand
For paver bedding, concrete sand (coarse, washed) is the usual pick. Mason sand is finer and used in mortar and play areas. Ask your supplier for their own tons-per-yard figure, since stone source and moisture shift it.
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. 1.2 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 1.1 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.
When to choose sand
Works well for:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Poor fit for:
- 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 14x28 area at 4 inches takes about 6.5 tons.
- Weight used here: about 1.35 tons per cubic yard.
Where estimates go wrong
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- 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.
