How Much Sand for a 8x16 Patio?
How much sand for a 8x16 patio: at 3 inches deep you need about 1.19 cubic yards, which is roughly 1.6 tons at 1.35 tons per yard. The patio covers 128 square feet, so every inch of depth adds about 0.40 yards.
Volume and tonnage calculator →The math for a 8x16 patio
- Area: 8 × 16 = 128 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 128 × 0.250 = 32.0 cu ft.
- Cubic yards: ÷ 27 = 1.19 yd³.
- Tons: × 1.35 = 1.6 tons.
The volume and tonnage calculator does this for any size.
Sand needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.40 | 0.5 | 0.6 |
| 2 in | 0.79 | 1.1 | 1.2 |
| 3 in | 1.19 | 1.6 | 1.8 |
| 4 in | 1.58 | 2.1 | 2.3 |
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 patio
Remove sod, level the area with a slight slope away from the house, and lay landscape fabric if weeds are a concern. Edging keeps loose material inside the patio footprint. This patio sees foot traffic and furniture, so match the depth to that load rather than to the minimum.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 1.8 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 patio as firm ground allows.
Where sand fits
Good uses:
- 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 3 inches takes about 2.5 tons.
- Weight used here: about 1.35 tons per cubic yard.
Common estimating mistakes
- 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.
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Forgetting that compaction shrinks loose material. A loose 4-inch spread of a dense-graded stone may finish closer to 3 inches after rolling.
