How Much Sand for a 4x50 Walkway?
How much sand for a 4x50 walkway: at 3 inches deep you need about 1.85 cubic yards, which is roughly 2.5 tons at 1.35 tons per yard. The walkway covers 200 square feet, so every inch of depth adds about 0.62 yards.
Volume and tonnage calculator →The math for a 4x50 walkway
- Area: 4 × 50 = 200 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 200 × 0.250 = 50.0 cu ft.
- Cubic yards: ÷ 27 = 1.85 yd³.
- Tons: × 1.35 = 2.5 tons.
The volume and tonnage calculator does this for any size.
Sand needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.62 | 0.8 | 0.9 |
| 2 in | 1.23 | 1.7 | 1.8 |
| 3 in | 1.85 | 2.5 | 2.8 |
| 4 in | 2.47 | 3.3 | 3.7 |
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. 2.8 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 this size bulk delivery is usually the practical choice.
- 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
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 10x20 area at 2 inches takes about 1.7 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.
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- Measuring only the main rectangle. Aprons, turnouts and curved edges add real square footage.
