Sand Calculator, Bags or Bulk
Walk into a yard and ask for sand. You could be handed any one of six products. They’re priced by the ton, planned by the square foot, and bagged by the pound. So this sand calculator starts with which sand the job actually needs, then hands you the volume, the tonnage and the sack count together.
Your result
What to order
1 tons (0.74 yd³) of masonry / mason sand for 240 sq ft at 1" deep
Quarries sell sand by weight and load it by volume, so quote the tonnage and let them convert.
- Area covered
- 240 sq ft at 1" deep
- Bags against bulk
- 40 sacks at 50 lb is 1 tons. Above about 27 bags the handling alone usually decides it, whatever the price works out at.
- Will it fit in a pickup?
- A half-ton pickup safely takes about 0.46 yd³ of sand, so your 0.74 yd³ is roughly 2 trips. Sand is among the heaviest materials by volume, so the bed fills by weight long before it looks full.
- How this is worked out
- 240 sq ft × 1" ÷ 12 ÷ 27 = 0.74 yd³ × 2,700 lb ÷ 2,000 = 1 tons
What is landscaping sand?
Sand is a word doing several jobs at once. In a yard it means half a dozen different products, sorted by how coarse the grains are and how thoroughly they've been washed. They cost different amounts and they don't substitute for each other.
That's the first thing worth knowing, and it catches people out at the counter rather than on the driveway. Ask for sand and you'll be asked which one, and the honest answer depends on what's going on top of it.
As for the quantity, sand is the densest thing most people will ever have delivered to a house. A cubic yard weighs more than a small car's payload. So the figure decides how it arrives, not just what it costs, and getting it wrong means either a wasted trip or an overloaded truck.
Calculate how much sand you need
Area in square feet × depth in inches ÷ 324 = cubic yards. It lands there directly, because a cubic yard spread an inch deep covers 324 square feet. Then multiply those yards by the weight of your grade to reach tons, which is the unit a quarry actually quotes in.
A 240 sq ft patio on a 1 inch bedding course works out at 0.74 cubic yards. In paver sand that’s 1 tons, or 40 fifty-pound bags if you were buying it in sacks. The same patio bedded at two inches, which people do reach for, would be 1.48 yards and a patio that settles into ruts within a season.
Measure the area, not the perimeter of the project. Got a path running round two sides of a patio? That’s a separate rectangle. Add it as its own area rather than rounding the patio up to swallow it. On a large area, every extra inch of depth is another delivery, so it pays to do this once properly.
Sand type: masonry, concrete, play, paver, fill
Sand isn’t one material. Three things separate the types: grain size, whether it has been washed, and whether the grains are rounded or angular. Angular sand locks together and holds a level. Rounded sand rolls and stays loose. That’s exactly what you want in a sandbox, and exactly what you don’t want under a paver.
| Sand | Grain | Lb per yd³ | What it is for |
|---|---|---|---|
| Masonry / mason sand | Fine, washed | 2,700 | Mortar, block work and under pavers as bedding |
| Concrete / sharp sand | Coarse, angular | 2,600 | Mixing concrete, and base under slabs |
| Paver bedding sand | Coarse, washed | 2,700 | The 1 inch setting bed under pavers |
| Play sand | Very fine | 2,400 | Sandboxes and play areas, washed and screened twice |
| Fill sand | Unwashed, mixed | 2,900 | Backfill, raising grade and bedding pipe |
| Leveling / topdressing sand | Fine, screened | 2,600 | Levelling low spots in a lawn |
Read across the weight column and you’ll see why the type matters. Fill sand at 2,900 lb a yard against play sand at 2,400 is a spread of about 21%. On a five-yard order that’s most of a ton either way. Swapping one sand for another because it was in stock changes both the tonnage and how the job performs.
Masonry sand, and where mason sand differs
Masonry sand is fine, washed and evenly graded. The coarse particles get screened out, because those are what stop mortar sliding smoothly off a trowel. Mason sand is the same thing under a shorter name. Ask for either at any yard and you get the same pile.
Its main job is mortar. Brick, block and stone, mixed about three parts sand to one part cement. It’s also the default for paver joints and for bedding under flagstone. Anywhere you want a smooth, even, fine sand. At 2,700 lb a cubic yard, one yard is roughly 1.35 tons, or 54 fifty-pound bags.
So where is it the wrong answer? Structural bedding. The grains are fine and rounded, so masonry sand compacts less predictably than the coarse angular concrete sand a paver setting bed calls for. Plenty of patios sit on it and most are fine. But if vehicles will drive on it, use concrete sand and save the mason sand for the joints.
Results in yards, tons and bags, and which one to order in
Three units for one material, and they rarely agree. Quarries price by the ton and load by the bucket. Landscapers plan by the cubic yard, because that’s how depth math works. Every big-box store sells it by the fifty-pound sack. A quote in one unit tells you almost nothing about a quote in another.
A cubic yard of masonry sand is 1.35 tons, or about 54 bags. So a ton is a little under three quarters of a yard. And a yard is most of a pallet of sacks. Comparing a bulk price against a bag price? Convert both to the same unit first. The gap is usually wider than it looks.
Order in whatever unit your supplier quotes. Just confirm which one they mean. The most expensive mistake on a sand order is reading a per-ton price as a per-yard one. That makes a load look about a third cheaper than it is, and you find out when the bill lands.
Sand coverage and depth guide
One cubic yard covers 324 sq ft at 1 inch. At 2 inches it does 162, and at 4 inches 81. Per ton, the numbers shift with the grade. A ton of light play sand is more cubic yards than a ton of heavy fill.
| Depth | Sq ft per cubic yard | Sq ft per ton | Typical use |
|---|---|---|---|
| 0.5" | 648 | 480 | lawn leveling |
| 1" | 324 | 240 | paver bedding |
| 2" | 162 | 120 | sandbox |
| 4" | 81 | 60 | base course |
| 6" | 54 | 40 | sandbox fill |
Use the middle column to plan and the right-hand one to order. Coverage per cubic yard is fixed geometry, so it never moves. Coverage per ton drops as the sand gets heavier. A ton of fill sand goes noticeably less far than a ton of play sand at the same depth. Quoted in tons but planned in yards? That column is where they meet.
The depth to be strict about is the paver bedding course. One inch, screeded flat, and no more. The sand is there to seat the paver, not to level the base beneath it. Every extra inch is somewhere the pavers can sink unevenly once traffic starts, and it’s the most common reason a patio goes wavy in its second year.
Everything else on the table is more forgiving. Leveling turf wants half an inch, because the grass has to grow through it. A sandbox wants four to six, because children dig. Bedding under pipe or slab wants four or more, because it gets compacted. Only the paver course has one right answer.
Sand weight per yard, and what a truck can take
Between 2,400 and 2,900 lb per cubic yard dry. Add several hundred pounds after rain. Sand is one of the heaviest materials by volume in landscaping. Heavier than topsoil, heavier than most gravels. Which makes it a poor thing to collect yourself.
A half-ton pickup rated at around 1,250 lb of payload takes roughly 0.46 of a cubic yard of masonry sand before it’s at its limit. Not one yard. Under half. The bed will still look nearly empty, which is how people end up driving home overloaded without realising it.
At the other end, a tandem dump rated for 14 tons carries about 10.4 cubic yards. Those two numbers hold most of the practical advice. Anything above half a yard is worth delivering. Anything above ten yards is one load rather than two.
Leveling a lawn with sand, and when not to
Half an inch a pass, spread and worked in with the back of a rake so the grass still shows through. Half an inch across 1,000 sq ft is 1.5 cubic yards. Repeat the following season if the lawn is still uneven rather than going deeper in one go.
Pure sand is the wrong choice on most lawns. On clay it builds a layer that water sits on top of, so drainage gets worse rather than better. A sand and compost topdressing mix does the same leveling job without that problem. So does straight compost, which is why the compost calculator has a topdressing rate built into it.
Sand leveling belongs on sandy or free-draining soil. It belongs on golf and sports turf, where the whole profile was built on sand. And it belongs in small hollows and animal damage, not across a whole lawn. If the ground underneath moved, sand on top only treats the symptom.
What sand costs
Roughly $25 to $60 a ton collected for bulk sand, and $40 to $90 a ton delivered, with fill sand cheapest and washed play sand dearest. Per cubic yard that’s about $34 to $81 collected.
Bagged sand runs $5 to $9 for a fifty-pound sack. At $6 a bag that works out at $324 a cubic yard. Roughly four times the bulk price. And the crossover comes early. Above about half a yard, or 27 bags, bulk wins even with delivery on top.
Delivery gets charged per load, not per ton. Usually $75 to $150 inside a normal radius. So one bigger order almost always beats two small ones. And distance from the quarry moves the delivered price more than the sand does. Call two or three yards and ask for the delivered rate rather than comparing pickup prices.
Sand questions
How much sand do I need?
Square feet × depth in inches ÷ 324 gives cubic yards, then multiply by the density of that sand for tons. A 240 sq ft patio on a 1 inch bedding course takes 0.74 cubic yards, which is about 1 tons or 40 fifty-pound bags.
How much sand do I need calculator?
Enter the area and the depth above and it returns all three units at once. The part worth setting properly is the sand type: fill sand at 2,900 lb a yard and play sand at 2,400 lb a yard give tonnages about 21% apart for the same hole.
How many bags of sand do I need?
Divide the total weight by the bag weight. At 2,700 lb per cubic yard and 50 lb per sack, one cubic yard is about 54 bags. Bags are sold by weight rather than volume, so the count comes off the tonnage, not the cubic yards.
How much sand is in a cubic yard?
27 cubic feet, weighing roughly 2,400 to 2,900 lb depending on the grade and how wet it is. That’s 1.35 tons for a typical masonry sand, and about 54 fifty-pound bags if you were buying the same volume in sacks.
How much sand to level a yard?
Half an inch a pass, and repeat rather than going deeper. Half an inch over 1,000 sq ft is 1.5 cubic yards. Burying grass under more than that in one go kills it, so leveling a badly uneven lawn is a job across two or three seasons.
How much sand will I need for a sandbox?
Length × width × depth in feet, divided by 27. A 6 by 6 ft box filled 6 inches deep is 0.67 cubic yards, or about 32 bags of play sand. Use washed and screened play sand rather than builders sand, which is sharp and stains.
