Sand Calculator
Calculate how many cubic yards, tons, or bags of sand you need for any project — paver base, sandbox, volleyball court, concrete mix, or landscaping. Includes bulk vs. bag cost comparison.
Whether you're laying a paver patio, filling a sandbox, or mixing concrete, this calculator handles the math. Select your sand type below, enter the area dimensions and depth, and you'll instantly see cubic yards, tons, bag counts, and a bulk vs. bag cost comparison. A 10% waste allowance is included by default — industry standard for most residential projects.
Sand is one of the most common bulk materials in construction and landscaping, used in everything from paver bases to sandboxes to concrete mixes. Estimating the correct quantity avoids costly overages and frustrating shortfalls — especially when a delivery truck has a minimum order and a per-trip fee. The math is simple volume calculation, but the density conversion from volume to weight is where most people trip up.
How to calculate sand yourself
Every sand estimate starts with the same three measurements: length, width, and depth. Sand fills a rectangular volume, and the formula is the same one used for any fill material:
Because depth is almost always given in inches rather than feet, divide inches by 12 before multiplying. For example, a 12 ft × 12 ft patio with 2 inches of bedding sand: 12 × 12 × (2 ÷ 12) = 24 cubic feet. To convert to cubic yards — the standard unit for bulk sand orders — divide by 27: 24 ÷ 27 = 0.89 cubic yards. In metric, the equivalent calculation uses metres and centimetres (3.66 m × 3.66 m × 5.1 cm = 0.68 m³).
After calculating raw volume, add a waste allowance. The industry standard for simple rectangular fills is 10%, which accounts for uneven subgrade, minor spillage, and the natural tendency of sand to settle. For curved areas or uneven terrain, use 15%. So the patio example becomes 0.89 × 1.10 = 0.98 cubic yards — effectively one yard.
The final step is converting volume to weight, because bulk sand is sold by the ton while bagged sand is sold by pound. Sand density varies by type, but dry masonry sand weighs approximately 2,700 lb per cubic yard (1,602 kg/m³). Multiply your volume by the appropriate density to get the tonnage for ordering.
Types of sand and their densities
Not all sand is the same. The grain size, shape, and mineral composition determine both the density and the appropriate application. Using the wrong type causes problems ranging from shifting pavers to unsafe play surfaces.
| Sand type | Density (lb/yd³) | Density (kg/m³) | Tons/yd³ | Common uses |
|---|---|---|---|---|
| Masonry / all-purpose | 2,700 | 1,602 | 1.35 | General fill, leveling, mortar mix |
| Play sand | 2,500 | 1,483 | 1.25 | Sandboxes, playgrounds, volleyball courts |
| Paver / jointing sand | 2,700 | 1,602 | 1.35 | Bedding layer under pavers, joint filling |
| Coarse / concrete sand | 2,835 | 1,682 | 1.42 | Concrete mixes, drainage backfill |
| Fine / beach sand | 2,500 | 1,483 | 1.25 | Decorative landscaping, mortar fine mix |
| Fill sand | 3,000 | 1,779 | 1.50 | Backfilling trenches, grading, structural fill |
Densities listed above are for dry, loose sand. Wet sand is significantly heavier — moisture can increase weight by 20–30%, which matters for vehicle payload capacity. A standard pickup truck typically holds one cubic yard of dry sand (roughly 1.35 tons for masonry sand), but always verify against your truck’s payload rating. Most half-ton pickups have a payload capacity of 1,000 to 1,500 lbs, meaning they can safely carry about half a cubic yard of sand at most.
When purchasing from a supplier, specify the sand type by name. “Sand” alone is ambiguous — a landscape yard’s default may be fill sand when you needed play sand, or vice versa. If ordering for a paver installation, ask for “washed concrete sand” or “manufactured sand” for the base, and “polymeric sand” or “fine mason sand” for the joints.
Sand depth guide by project type
Choosing the correct depth is just as important as choosing the right sand type. Too shallow and the sand fails to perform its function; too deep and materials are wasted or — in the case of paver bases — structural integrity is compromised.
| Project | Recommended depth | Sand type | Notes |
|---|---|---|---|
| Paver base (bedding) | 1 in (2.5 cm) | Coarse / concrete sand | Screeded level; do not exceed 1.5 in or pavers will rock |
| Paver joints | Full joint depth | Polymeric sand | Swept in after pavers are set; typically 3/16–3/8 in wide |
| Sandbox | 6–8 in (15–20 cm) | Play sand | Must be washed, rounded-grain sand; avoid silica dust |
| Volleyball court | 12–18 in (30–46 cm) | Play or masonry sand | Regulation court is 59 × 29.5 ft (18 × 9 m) |
| Pool base (above-ground) | 2 in (5 cm) | Mason sand | Leveling bed under liner; must be free of stones |
| Lawn top dressing | 0.25–0.5 in (6–13 mm) | Fine sand/compost mix | Levels low spots; excessive depth smothers grass |
| Concrete mix | Ratio-based | Coarse concrete sand | Standard ratio: 2 parts sand to 1 part cement by volume |
| Trench backfill | Varies | Fill sand | Compact in 6–8 in lifts for structural stability |
For paver installations, the 1-inch bedding layer is critical. Contractors screed this layer flat using guide rails set at the correct height, then set pavers directly onto the sand. A layer thicker than 1.5 inches (3.8 cm) allows pavers to sink unevenly under foot traffic. The bedding sand is separate from the gravel base underneath, which is typically 4–6 inches (10–15 cm) of compacted crushed stone. The total base system — gravel plus sand — provides drainage and load distribution.
Bulk delivery vs. bagged sand
The decision between bulk delivery and bagged sand almost always comes down to project volume and access. The cost difference is dramatic at scale.
A 50 lb bag of sand at a home improvement store costs $4–$8 depending on type and location. One cubic yard of masonry sand weighs about 2,700 lbs, which means you need 54 bags to equal one yard. At $5.50 per bag, that totals $297 per cubic yard in bags. Bulk masonry sand, delivered by the ton, typically costs $25–$55 per ton — or roughly $34–$74 per cubic yard. The savings are enormous: bulk sand costs one-quarter to one-fifth of bagged sand per unit volume.
The trade-off is convenience. Bags require no minimum order, no delivery scheduling, and no place to dump a large pile. For small projects — a single sandbox, a few stepping stones, a minor repair — bags are practical and hassle-free. But for anything approaching one cubic yard or more, the economics strongly favor bulk.
Most landscape supply yards deliver bulk sand for free above 2–3 tons. Below that threshold, expect a delivery fee of $50–$100. Some suppliers have a one-ton minimum order. When ordering, specify dry weight — wet sand weighs more, and you should not pay extra for water weight.
Volume-to-weight conversion
The relationship between volume and weight depends entirely on density, and sand density varies by type, moisture content, and how tightly it is packed. The calculator above handles these conversions automatically, but understanding the math helps when verifying quotes from suppliers.
As a quick reference: one cubic yard of dry masonry sand weighs about 2,700 lbs (1.35 tons). One cubic foot weighs about 100 lbs. These round numbers make mental math easy on the job site — a wheelbarrow holds about 3 cubic feet, so a full barrow of sand weighs roughly 300 lbs.
For metric users, one cubic metre of dry masonry sand weighs approximately 1,602 kg (1.6 tonnes). One cubic metre equals 1.308 cubic yards, and one tonne equals 1.102 short tons. When converting quotes between American suppliers (who use short tons of 2,000 lbs) and international sources (who use metric tonnes of 1,000 kg), the difference is about 10%.
Moisture content is the largest variable. Sand delivered from an outdoor stockpile after rain can weigh 20–30% more than bone-dry sand due to water trapped between grains. A cubic yard of wet sand may weigh 3,200–3,500 lbs instead of 2,700 lbs. Reputable suppliers quote dry weight, but it is worth confirming. If you are paying by the ton and the sand is visibly wet, you are effectively paying for water.
Estimating sand costs
Sand pricing varies by type, region, and purchase method. The following ranges reflect typical 2025 U.S. residential pricing:
| Purchase method | Price range | Cost per yd³ (approx.) | Best for |
|---|---|---|---|
| Bulk delivery (per ton) | $25–$55/ton | $34–$74/yd³ | Projects over 0.5 yd³ |
| 50 lb bags (retail) | $4–$8/bag | $216–$432/yd³ | Small repairs, single items |
| Specialty sand (polymeric) | $20–$35/bag (50 lb) | N/A | Paver joints only |
| Pickup (self-haul, per ton) | $15–$35/ton | $20–$47/yd³ | Small loads if you have a truck |
The self-haul option — driving your truck or trailer to a landscape yard — offers the lowest per-ton price but requires a suitable vehicle. A full cubic yard of dry masonry sand weighs 2,700 lbs, which exceeds the payload capacity of most half-ton pickup trucks. A three-quarter-ton or one-ton truck handles a full yard safely. Always check your vehicle’s Gross Vehicle Weight Rating (GVWR) minus its curb weight to determine true payload capacity.
Delivery fees typically range from $50 to $150 and are often waived for orders above a certain tonnage (commonly 2–3 tons). When comparing quotes, calculate the total delivered cost per cubic yard including the delivery fee. A supplier quoting $30/ton with a $100 delivery fee may be cheaper overall than one quoting $25/ton with a $150 fee, depending on your order size.
Ordering and delivery tips
A few practical considerations can save time and money when ordering bulk sand:
Placement matters. The delivery truck will dump sand in a pile, typically 4–6 feet high for a single-yard load. Specify exactly where you want it placed — on a tarp in the driveway, on a hard surface near the work area, or directly on the prepared subgrade if timing permits. Sand dumped on grass kills the lawn underneath within days. Placing a tarp under the pile makes cleanup dramatically easier.
Order on dry days. Wet sand is heavier to move, harder to screed level, and more difficult to compact evenly. If you cannot avoid delivery on a rainy day, cover the pile with a tarp immediately. Saturated sand also does not sweep cleanly into paver joints.
Verify the load. Reputable suppliers weigh trucks before and after loading on a certified scale and provide a weight ticket. Ask for the ticket, especially for large orders. Eyeballing a pile is unreliable — sand compresses during transport, and a pile that looks small may still be the correct weight.
Schedule timing. If sand is for a paver base, coordinate delivery with your project timeline. Sand left sitting for weeks can be contaminated with leaves, debris, or weed seeds. Ideally, the sand arrives the day before or the morning of the installation.
For projects involving both a gravel base and sand bedding (such as paver patios), order the gravel first, compact it, and then order the sand. Mixing up the sequence wastes material and creates structural problems.
Common mistakes to avoid
Several errors recur in sand estimation and installation. Awareness of these saves both money and rework:
Using the wrong sand type. Play sand and construction sand are not interchangeable. Play sand is washed, screened, and free of sharp edges — safe for children. Using unwashed construction sand in a sandbox exposes children to dust and debris. Conversely, using expensive play sand for a paver base wastes money on a product whose fine grain provides less structural support than coarser alternatives.
Ignoring compaction. Loose sand settles 10–15% after compaction with a plate compactor. If your calculation targets finished depth, order enough for the pre-compaction depth. For a 1-inch finished bedding layer, start with approximately 1.15 inches of loose sand.
Skipping the waste allowance. Uneven subgrade, small spills, and material left in the truck bed all consume sand beyond the theoretical calculation. A 10% waste factor costs a few dollars on a typical residential project but prevents a shortfall that would require a second order, a second delivery fee, and a delay.
Exceeding paver base depth. A bedding layer deeper than 1.5 inches (3.8 cm) allows pavers to rock and shift under load. If the subgrade is uneven, correct it with gravel, not extra sand. The sand layer is a precision leveling course, not structural fill.
Forgetting moisture weight for hauling. A half-ton pickup truck rated for 1,500 lbs of payload can safely carry about half a cubic yard of dry sand. Loading a full yard (2,700 lbs dry, potentially 3,400+ lbs wet) risks overloading the vehicle, damaging the suspension, and creating an unsafe driving condition. Verify your vehicle’s payload capacity before self-hauling.
Not accounting for joint sand separately. Paver joint sand (swept into gaps between pavers) is a separate quantity from the bedding sand underneath. A common rule of thumb is 1 cubic foot of joint sand per 30–40 square feet of paver surface for standard 3/8-inch joints. Forgetting this line item leaves the job incomplete.
