Bags of Sand for a 8x24 Patio
How many bags of sand for a 8x24 patio: at 2 inches deep you need about 32.0 cubic feet, which is 64 bags of the common 0.5 cubic foot size. If your store sells sand in 50-pound bags instead, figure about 64 bags, since sand weighs roughly 100 pounds per cubic foot.
Volume and tonnage calculator →Bag count by depth
| Depth | Cubic feet | 0.5 cu ft bags | 50 lb bags (approx.) |
|---|---|---|---|
| 1 in | 16.0 | 32 | 32 |
| 2 in | 32.0 | 64 | 64 |
| 3 in | 48.0 | 96 | 96 |
| 4 in | 64.0 | 128 | 128 |
How to figure it
- Area: 8 × 24 = 192 sq ft.
- Volume: 192 × (2 ÷ 12) = 32.0 cu ft.
- Bags: 32.0 ÷ 0.5 = 64 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 32.0 cubic feet is 1.19 yards, about 1.6 tons. At this size, a bulk delivery usually beats a cart full of bags once you count trips. Compare the bag price × 64 against a bulk quote for 1.8 tons delivered.
About sand
Sand weight changes a lot with moisture. Damp sand can weigh noticeably more per yard than dry sand, so a ton of wet sand covers less area than the same ton dry.
Install tips for a patio
- Dig and level. Remove sod and set the base slightly below the surrounding grade.
- Edge it. Steel, plastic or stone edging keeps material in place.
- Spread in layers. Rake to depth, then tamp or wet and compact.
- Buy a few extra. Grab 5 to 10 percent more bags for settling and touch-ups.
The volume and tonnage calculator handles other sizes and depths.
When to choose sand
Good uses:
- 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 12x24 area at 2 inches takes about 2.4 tons.
- Weight used here: about 1.35 tons per cubic yard.
Common estimating mistakes
- 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.
- 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.
