How Much Sand for a 4x15 Walkway?
How much sand for a 4x15 walkway is a quick volume problem. 60 square feet at 3 inches comes to 0.56 cubic yards. Sand usually weighs about 1.3 to 1.5 dry tons per cubic yard, so plan on roughly 0.8 tons.
Volume and tonnage calculator →The math for a 4x15 walkway
- Area: 4 × 15 = 60 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 60 × 0.250 = 15.0 cu ft.
- Cubic yards: ÷ 27 = 0.56 yd³.
- Tons: × 1.35 = 0.8 tons.
The volume and tonnage calculator does this for any size.
Sand needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.19 | 0.2 | 0.3 |
| 2 in | 0.37 | 0.5 | 0.6 |
| 3 in | 0.56 | 0.8 | 0.8 |
| 4 in | 0.74 | 1.0 | 1.1 |
About sand
For paver bedding, concrete sand (coarse, washed) is the usual pick. Mason sand is finer and used in mortar and play areas. 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. 0.8 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 0.8 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
Best suited to:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Think twice 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 10x20 area at 2 inches takes about 1.7 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- 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.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
