Bags of Sand for a 14x30 Patio
How many bags of sand for a 14x30 patio: at 2 inches deep you need about 70.0 cubic feet, which is 140 bags of the common 0.5 cubic foot size. If your store sells sand in 50-pound bags instead, figure about 140 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 | 35.0 | 70 | 70 |
| 2 in | 70.0 | 140 | 140 |
| 3 in | 105.0 | 210 | 210 |
| 4 in | 140.0 | 280 | 280 |
How to figure it
- Area: 14 × 30 = 420 sq ft.
- Volume: 420 × (2 ÷ 12) = 70.0 cu ft.
- Bags: 70.0 ÷ 0.5 = 140 bags (round up).
Bags or bulk?
A cubic yard is 27 cubic feet, so 70.0 cubic feet is 2.59 yards, about 3.5 tons. At this size, a bulk delivery usually beats a cart full of bags once you count trips. Compare the bag price × 140 against a bulk quote for 3.9 tons delivered.
About sand
For paver bedding, concrete sand (coarse, washed) is the usual pick. Mason sand is finer and used in mortar and play areas.
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.
Where sand fits
Best suited to:
- Paver and flagstone bedding
- Leveling under above-ground pools (with the right product)
- Filling joints and backfilling pipe
Poor fit 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 3 inches takes about 5.6 tons.
- Weight used here: about 1.35 tons per cubic yard.
Mistakes that throw off the order
- Ignoring the base. A thin surface layer over soft soil fails early no matter how much material is on top.
- 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.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
