How to calculate how much sand you need
Bulk sand is sold by the cubic yard or the ton; bagged sand is sold by weight, and most bags also state a volume. Work out the volume, then convert.
cubic yards = cubic feet ÷ 27
tons = cubic yards × 1.40–1.55 (damp sand)
bags = cubic feet ÷ cubic feet per bag, rounded up
Example: bedding sand for a 12 × 12 ft paver patio
- Volume at 1 inch: 12 × 12 × 1 ÷ 12 = 12 cu ft = 0.44 cu yd
- Bags: 12 ÷ 0.5 = 24 bags of 0.5 cu ft, or 12 ÷ 0.6 = 20 bags of 0.6 cu ft
- In bulk: 0.44 × 1.40–1.55 = 0.62–0.69 tons of damp sand
Oregon State University Extension spreads 1 to 1½ inches and screeds it down to 1 inch.[1] Spread at 1½ inches, the same patio takes 18 cu ft, or 36 bags of 0.5 cu ft. SAKRETE’s own tables agree with this math: 17 bags of its Leveling Sand for 100 sq ft at 1 inch, and 34 bags of its Paver Base (a bedding sand) at 2 inches.[2][3] With Extra for waste set to 0, the calculator gives 17 and 34 (18 and 35 at the default 5%).
Example: an 8 × 8 ft play area
- Volume at the 12 in install depth: 8 × 8 × 12 ÷ 12 = 64 cu ft = 2.37 cu yd
- Weight: 2.37 × 1.40–1.55 = 3.3–3.7 tons of damp sand
- Bags: 64 ÷ 0.5 = 128 bags, so a bulk delivery is worth pricing
How deep to spread sand
| Use | Depth | Source |
|---|---|---|
| Bedding sand under pavers | 1 in, screeded, not compacted | ICPI Tech Spec 2[4]; OSU Extension[1] |
| Paver sand, QUIKRETE’s DIY instructions | 1–2 in | QUIKRETE[5] |
| Play area under equipment | 9 in after settling (install 12 in) | CPSC Public Playground Safety Handbook[6] |
| Sandbox for digging | the depth you want | No standard; use the box’s inside size |
For pavers, ICPI specifies concrete sand meeting ASTM C33 as bedding. It says not to use stone dust or screenings, and not to use the bedding sand to fill low spots in the base.[4]
In the CPSC handbook, 9 inches of sand protects to a fall height of 4 ft, a foot less than the same depth of pea gravel, and “loose-fill materials will compress at least 25% over time.” CPSC’s own example is to install 12 inches so that 9 inches remain.[6]
How much sand weighs
Water adds weight. Caterpillar’s handbook lists loose sand at 2,400 lb per cubic yard dry, 2,850 lb damp and 3,100 lb wet.[7] Most bulk sand arrives damp, so the calculator starts with damp sand; switch to dry if yours is dry.
| Sand | Tons per cu yd | Pounds per cu ft | Cu yd per ton | Sources |
|---|---|---|---|---|
| Sand, damp (typical as delivered) | 1.40–1.55 | 104–115 | 0.68 | [7][8][9] |
| Sand, dry | 1.20–1.45 | 89–107 | 0.75 | [7][9][10] |
“Cu yd per ton” uses the middle of the range. As a check, Kokosing, an Ohio aggregate producer, multiplies cubic yards by 1.5 to get tons for all its sands.[11]
Bag sizes
Most 50 lb bags of sand hold 0.5 cu ft, but not all. SAKRETE Multi-Purpose Sand yields 0.6 cu ft per 60 lb bag, and SAKRETE says its 50 lb bag of mason sand yields 0.6 cu ft where QUIKRETE’s 50 lb mason sand yields 0.5. Go by the yield printed on your bag.
| Product | Bag | Yield | Bags per cu yd | Covers at 1 in | Sources |
|---|---|---|---|---|---|
| QUIKRETE All-Purpose Sand (also sold in 60 and 70 lb bags) | 50 lb | 0.5 cu ft | 54 | 6.0 sq ft | [12][13] |
| QUIKRETE Play Sand | 50 lb | 0.5 cu ft | 54 | 6.0 sq ft | [12][14] |
| QUIKRETE Mason Sand | 50 lb | 0.5 cu ft | 54 | 6.0 sq ft | [15] |
| SAKRETE Natural Play Sand | 50 lb | 0.5 cu ft | 54 | 6.0 sq ft | [16] |
| SAKRETE Leveling Sand | 50 lb | 0.5 cu ft | 54 | 6.0 sq ft | [2] |
| Kolor Scape All-Purpose Sand | 44 lb | 0.5 cu ft | 54 | 6.0 sq ft | [17] |
| SAKRETE Multi-Purpose Sand | 60 lb | 0.6 cu ft | 45 | 7.2 sq ft | [18] |
| SAKRETE Mason Sand | 50 lb | 0.6 cu ft | 45 | 7.2 sq ft | [19] |
| SAKRETE Mason Sand | 80 lb | 0.8 cu ft | 34 | 9.6 sq ft | [19] |
The calculator counts both 0.5 and 0.6 cu ft bags.
Polymeric sand for paver joints
Polymeric (jointing) sand goes in the joints after the pavers are laid, so its coverage is in square feet of paving, not in volume. Coverage depends on joint width, paver thickness and paver shape, and the makers publish ranges, not single numbers:
| Product | Joints | Covers per bag | Package | Source |
|---|---|---|---|---|
| Alliance Gator SuperSand G2 | Narrow, ⅛–⅜ in | 65–85 sq ft | 50 lb bag, 2⅜ in pavers | [20] |
| Alliance Gator SuperSand G2 | Wide, ¾–1¼ in | 22–42 sq ft | 50 lb bag, 2⅜ in pavers | [20] |
| Techniseal HP NextGel | Narrow (not defined) | 60–120 sq ft | 50 lb bag | [21] |
| Techniseal HP NextGel | Wide (not defined) | 25–40 sq ft | 50 lb bag | [21] |
| SAKRETE PermaSand | ¼ in, 2 in pavers | 30–45 sq ft | 40 lb pail | [22] |
| QUIKRETE jointing sand (2011) | Regular pavers | 85–95 sq ft | 50 lb bag | [23] |
| QUIKRETE jointing sand (2011) | Tumbled pavers | 50–55 sq ft | 50 lb bag | [23] |
For the 144 sq ft patio above, Gator’s ranges work out to 2–3 bags with narrow joints and 4–7 bags with wide joints. Both Gator and Techniseal call for joints at least 1½ inches deep.[20][21]
Hauling sand
An 8 ft pickup bed holds about 2 cubic yards level, but Ford’s half-ton F-150 tops out at 2,440 lb of payload in its best configuration.[24][25] At 1.40–1.55 tons per cubic yard, 2,000 lb of damp sand is only 0.65–0.71 cubic yards, so the calculator counts pickup trips by weight. Single-axle dump trucks usually carry about 6 cubic yards and tandem trucks 12–14.[26]
Questions people ask
How can I calculate sand needed for an area?
Multiply length × width in feet by the depth in inches ÷ 12 to get cubic feet, and divide by 27 for cubic yards. Multiply cubic yards by 1.40–1.55 for tons of damp sand, or divide cubic feet by the bag’s yield (usually 0.5) for bags.
How much area will 50 lbs of sand cover?
Most 50 lb bags hold 0.5 cubic feet, which covers 6 sq ft at 1 inch deep or 3 sq ft at 2 inches. A bag that yields 0.6 cubic feet covers 7.2 sq ft at 1 inch.
How many 50 lb bags of sand make a cubic yard?
54 bags if each holds 0.5 cubic feet (27 ÷ 0.5), or 45 bags of 0.6 cubic feet.
How much area does 1 ton of sand cover?
One ton of damp sand is 17.4–19.3 cubic feet. That covers about 209–231 sq ft at 1 inch or 105–116 sq ft at 2 inches.
