How Much Sand for a 10x12 Patio?
How much sand for a 10x12 patio: at 3 inches deep you need about 1.11 cubic yards, which is roughly 1.5 tons at 1.35 tons per yard. The patio covers 120 square feet, so every inch of depth adds about 0.37 yards.
Volume and tonnage calculator →The math for a 10x12 patio
- Area: 10 × 12 = 120 sq ft.
- Depth in feet: 3 ÷ 12 = 0.250 ft.
- Cubic feet: 120 × 0.250 = 30.0 cu ft.
- Cubic yards: ÷ 27 = 1.11 yd³.
- Tons: × 1.35 = 1.5 tons.
The volume and tonnage calculator does this for any size.
Sand needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 1 in | 0.37 | 0.5 | 0.6 |
| 2 in | 0.74 | 1.0 | 1.1 |
| 3 in | 1.11 | 1.5 | 1.7 |
| 4 in | 1.48 | 2.0 | 2.2 |
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 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. For foot traffic and furniture, 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. 1.7 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
Works well for:
- 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 8x16 area at 3 inches takes about 1.6 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Assuming every supplier uses the same weight. Two yards selling the same product name can quote different tons per yard.
- 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.
