How Much Sand for a 4x25 Walkway?
How much sand for a 4x25 walkway: at 3 inches deep you need about 0.93 cubic yards, which is roughly 1.2 tons at 1.35 tons per yard. The walkway covers 100 square feet, so every inch of depth adds about 0.31 yards.
Volume and tonnage calculator →The math for a 4x25 walkway
- Area: 4 × 25 = 100 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 100 × 0.250 = 25.0 cu ft.
- Cubic yards: ÷ 27 = 0.93 yd³.
- Tons: × 1.35 = 1.2 tons.
The volume and tonnage calculator does this for any size.
Sand needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.31 | 0.4 | 0.5 |
| 2 in | 0.62 | 0.8 | 0.9 |
| 3 in | 0.93 | 1.2 | 1.4 |
| 4 in | 1.23 | 1.7 | 1.8 |
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. 1.4 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.
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
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 10x20 area at 3 inches takes about 2.5 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
