Volume and tonnage calculator →Sand for 4,000 sq ft by depth
| Depth | Cubic yards | Tons | Tons +10% |
|---|---|---|---|
| 1 in | 12.35 | 16.7 | 18.3 |
| 2 in | 24.69 | 33.3 | 36.7 |
| 3 in | 37.04 | 50.0 | 55.0 |
| 4 in | 49.38 | 66.7 | 73.3 |
Working it out
- 4,000 sq ft × (3 ÷ 12) ft = 1,000.0 cubic feet.
- ÷ 27 = 37.04 cubic yards.
- × 1.35 tons per yard = 50.0 tons.
About sand
For paver bedding, concrete sand (coarse, washed) is the usual pick. Mason sand is finer and used in mortar and play areas. Typical weight: 1.3 to 1.5 dry tons per cubic yard.
Getting the order right
- Measure odd shapes in pieces. Split curves and L-shapes into rectangles and add them.
- Add a margin. About 10 percent covers compaction and low spots.
- Bulk or bags. Bulk delivery is the practical choice here.
- Prep first. Remove sod, compact the subgrade and set edging before the stone arrives.
Use the volume and tonnage calculator for any other size.
Where sand fits
Works well for:
- 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 15x30 area at 2 inches takes about 3.8 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- 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.
- 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.
