How many bags of topsoil in a yard? The short answer is that it takes about 36 of the common 0.75 cubic foot bags, or 27 of the 1 cubic foot bags, to equal a single cubic yard of topsoil, because a cubic yard holds 27 cubic feet of material no matter what it is made of. If you are buying the larger 1.5 cubic foot bags you need 18 of them, and if you are buying the small 0.5 cubic foot bags it takes 54. The reason this trips people up is that bags are sold by volume in cubic feet, or sometimes by weight as a 40-pound bag, while bulk soil is sold by the cubic yard, and the two units do not line up in any obvious way until you do the division. This guide gives you a clear count for every common bag size, a bag-to-yard chart you can read at a glance, the number of cubic feet and cubic yards a single bag holds, how many bags usually sit on a pallet, what the bag sizes actually mean, and the honest cost and effort comparison between buying bags and ordering bulk. By the end you will know exactly how many bags your project needs and whether hauling them one at a time is worth it or whether a bulk delivery makes more sense.
Before you buy a stack of bags, work out how much soil you actually need by entering your area and depth into the Dirt Calculator or the Topsoil Calculator. Once you know your volume in cubic feet or yards, the bag counts below turn it straight into a shopping list.

How many bags of topsoil are in a yard?
A cubic yard of topsoil equals 27 cubic feet, so the number of bags it takes to make a yard depends entirely on how many cubic feet each bag holds. For the most common bag sizes, one cubic yard is about 36 bags at 0.75 cubic feet each, 27 bags at 1 cubic foot each, 18 bags at 1.5 cubic feet each, or 54 bags at 0.5 cubic feet each. Those four numbers cover almost every bag of topsoil you will find at a garden center or big-box store.
The math behind it is short. You take 27, the number of cubic feet in a cubic yard, and divide it by the cubic feet printed on the bag. Twenty-seven divided by 0.75 is 36, twenty-seven divided by 1 is 27, twenty-seven divided by 1.5 is 18, and twenty-seven divided by 0.5 is 54. There is nothing more to it than that, and once you know the bag size you can work out the count for any yardage in your head. Two yards of the 0.75 cubic foot bags is 72 bags, three yards is 108, and so on.
The one wrinkle is the 40-pound bag, which is sold by weight rather than volume. A 40-pound bag of typical topsoil holds roughly 0.75 cubic feet, so it takes about 36 of them to make a yard, the same as the 0.75 cubic foot bag. The catch is that weight-labelled bags vary with moisture and soil type, so a 40-pound bag might hold anywhere from about 0.5 to 0.75 cubic feet, which nudges the count upward if the soil is dense and wet. To turn your specific project into a yardage before you start counting bags, the Dirt Calculator does the area-and-depth math for you.
Why a yard equals 27 cubic feet
Every bag count in this guide comes back to one fact: a cubic yard contains 27 cubic feet. If that number feels arbitrary, it helps to picture the shape. A cubic yard is a cube that measures three feet on every side, because there are three feet in a yard. To find its volume you multiply the three dimensions together, so three feet by three feet by three feet gives you 27 cubic feet. That is the whole reason the number is 27 rather than something rounder, and it is the bridge between the world of bags, which are measured in cubic feet, and the world of bulk soil, which is measured in cubic yards.
This matters because bags and bulk are sold in different units, and suppliers rarely translate between them for you. A garden center sells you a bag marked 0.75 cubic feet, while a landscape yard sells you soil by the cubic yard, and unless you know that a yard is 27 cubic feet you have no way to compare the two. Once you hold that number in your head, every comparison becomes a simple division. It also explains why bag counts climb so fast. Because a single bag holds well under one cubic foot, and a yard holds 27 of them, you always end up needing dozens of bags to match even one modest bulk delivery.
The same 27 cubic feet governs coverage too, not just bag counts. One cubic yard of topsoil spread three inches deep covers about 100 square feet, and that figure comes straight from dividing 27 cubic feet by the quarter-foot depth. If you want the full breakdown of that conversion in both directions, the companion guide on how many cubic feet are in a yard of topsoil walks through it with its own examples, and understanding it makes every other topsoil number easier to reason about.
Bag-to-yard chart for every common bag size
The chart below is the fastest way to answer how many bags of topsoil are in a yard for whatever size bag you are holding. Find your bag size in the left column and read across to see how many bags make a full cubic yard, a half yard, and a two-yard order. The counts are rounded up to whole bags where a partial bag would otherwise be needed, because you cannot buy two-thirds of a bag at the store.
| Bag size | Cubic feet per bag | Bags per 1 yard | Bags per 0.5 yard | Bags per 2 yards |
|---|---|---|---|---|
| Small bag | 0.5 cu ft | 54 | 27 | 108 |
| Standard bag | 0.75 cu ft | 36 | 18 | 72 |
| 40 lb bag (by weight) | ~0.75 cu ft | ~36 | ~18 | ~72 |
| Large bag | 1 cu ft | 27 | 14 | 54 |
| Extra-large bag | 1.5 cu ft | 18 | 9 | 36 |
| Jumbo bag | 2 cu ft | 14 | 7 | 28 |
Reading down the middle column shows just how much the bag size changes the shopping list. Buying the small half-cubic-foot bags means hauling 54 of them for a single yard, while the two-cubic-foot jumbo bags cut that to 14. The soil volume is identical either way, so if bags are your route it usually pays to buy the largest size your store stocks and your back can lift. A yard of the 1.5 cubic foot bags is only 18 pieces to carry instead of 36 or 54, which is a meaningful difference when you are loading a car and unloading it again. To convert your own bed into a yardage before reading the chart, run the numbers through the Dirt Calculator.
How many cubic feet are in a bag of topsoil?
A bag of topsoil holds somewhere between 0.5 and 2 cubic feet, and the exact figure is printed on the front of the bag if it is sold by volume. The most common size by far is 0.75 cubic feet, followed closely by the 1 cubic foot bag, with 0.5, 1.5, and 2 cubic foot bags showing up depending on the brand and the store. When a bag is sold by weight instead, as a 40-pound bag, the volume is not printed, but it works out to roughly 0.75 cubic feet for typical topsoil.
Knowing the cubic feet in a bag is the key that unlocks every other number here, because cubic feet is the unit that connects bags to yards. If you know your project needs, say, 18 cubic feet of soil, you can divide by the bag size to get the count directly: 18 divided by 0.75 is 24 standard bags, or 18 divided by 1 is 18 large bags. This is why it is worth checking the cubic feet on the bag rather than the weight, since the volume is what actually fills your bed. Two bags labelled 40 pounds each can hold slightly different volumes if one soil is denser than the other, but two bags labelled 0.75 cubic feet hold the same amount of soil every time.
For the 40-pound bag specifically, the roughly 0.75 cubic foot figure comes from typical topsoil weighing about 74 to 100 pounds per cubic foot depending on moisture. At around 53 pounds per cubic foot for loose bagged soil, 40 pounds works out near three-quarters of a cubic foot, though damp, heavy soil can compress that toward 0.5 cubic feet per 40-pound bag. If you want the deeper story on how much a bag weighs and why, the guide on how much a yard of topsoil weighs covers the weight side in full, including per-bag figures.
How many cubic yards are in a bag of topsoil?
Going the other direction, a single bag of topsoil holds only a small fraction of a cubic yard, which is why bags feel so small next to a bulk pile. A 0.75 cubic foot bag holds about 0.028 of a cubic yard, a 1 cubic foot bag holds about 0.037 of a yard, and even a large 2 cubic foot bag holds only about 0.074 of a yard, well under a tenth. You get these figures by dividing the bag’s cubic feet by 27, the number of cubic feet in a yard.
These tiny fractions explain the whole economics of bagged versus bulk soil. Because one bag is such a small slice of a yard, you always need a lot of them, and each one costs money, plastic, and lifting effort. A single yard delivered as bulk arrives in one drop, while the same yard in bags is 27 to 54 separate items you buy, load, carry, open, and empty. For a small raised bed or a container or two, that handful of bags is convenient and there is no delivery to schedule. For anything approaching a full yard, the fractions start working against you fast.
The practical takeaway is that if your project needs a meaningful fraction of a yard, it is worth pausing to count how many bags that really means before you fill a cart. A project that sounds modest, like topping up a 10 by 10 foot bed at two inches deep, needs about 17 cubic feet of soil, which is roughly 23 standard bags. That is a heavy trunk-load and a lot of empty plastic, and it is right around the point where a bulk delivery or the Topsoil Calculator is worth a look before you commit to bags. Working the volume out first, rather than guessing the bag count, saves both trips and money.
How many 40 lb bags of topsoil make a yard?
The 40-pound bag is the one people ask about most, because it is the default size at many big-box stores and it is labelled by weight rather than volume, which makes the yard math less obvious. The working answer is that it takes about 36 of the 40-pound bags to make one cubic yard of topsoil, the same as the 0.75 cubic foot bag, because a 40-pound bag of typical soil holds close to 0.75 cubic feet.
That 36-bag figure is a solid planning number, but it is worth understanding why it can drift. A bag sold by weight always holds 40 pounds, but the volume that 40 pounds occupies depends on how dense and wet the soil is. Light, dry, fluffy topsoil packs less into a pound, so a 40-pound bag of it holds closer to 0.75 cubic feet, keeping you near 36 bags a yard. Heavy, damp, clay-rich soil packs more weight into less space, so a 40-pound bag of it might hold only 0.5 to 0.6 cubic feet, which pushes the count up toward 45 to 54 bags a yard. This is one reason volume-labelled bags are easier to plan with than weight-labelled ones.
For a real order, the safe move is to plan on 36 forty-pound bags per yard and buy a couple extra rather than come up short, since running out mid-project means another trip to the store. If your store stocks both weight-labelled and volume-labelled bags, the volume-labelled 0.75 cubic foot bag gives you a more predictable count for the same rough size. Either way, once you know your project’s volume, the arithmetic is quick, and the guide to how much topsoil you need shows how to get from your bed’s dimensions to that volume before you start counting bags.
How many bags of topsoil come on a pallet?
If you are buying enough bags to justify a pallet, the count depends on the bag size and the store, but most pallets of topsoil hold somewhere between about 40 and 56 bags. A pallet of the common 40-pound or 0.75 cubic foot bags often runs around 50 bags, give or take, while pallets of larger 1.5 or 2 cubic foot bags hold fewer because each bag is bulkier. The pallet is stacked and shrink-wrapped so it can be moved by forklift, which is why buying a full pallet often comes with a better per-bag price and sometimes free or reduced delivery.
Here is where the yard math becomes useful for a bigger purchase. A pallet of roughly 50 of the 0.75 cubic foot bags holds about 37 cubic feet of soil, which is a little under a cubic yard and a half. A pallet of 56 such bags is about 42 cubic feet, closer to a yard and a half. So a single pallet of standard bags lands you somewhere in the region of 1.4 to 1.5 cubic yards of topsoil, which is a helpful way to sanity-check whether a pallet covers your project or whether you need two. If your job needs three or four yards, that is two or three pallets of bags, and at that scale bulk delivery almost always wins on both price and effort.
Pallet counts do vary by brand and region, so the number stamped on the wrap or listed online is the one to trust for your specific product. As a rule of thumb, though, treating a pallet as roughly 50 standard bags and roughly 1.4 to 1.5 yards of soil gets you close enough to plan around. Before you order a pallet, it is worth confirming your total volume with the Dirt Calculator so you know how many pallets, or how many bulk yards, your project actually calls for.
Topsoil bag sizes explained
Topsoil bags come in a handful of standard sizes, and knowing what each one means saves you from guessing at the register. Volume-labelled bags are marked in cubic feet, and the common sizes are 0.5, 0.75, 1, 1.5, and 2 cubic feet. Weight-labelled bags are marked in pounds, most often as a 40-pound bag, and occasionally as a 50-pound bag. The volume label tells you directly how much space the soil fills, while the weight label tells you what you are lifting but leaves the volume to be estimated.
The 0.75 cubic foot bag and the 40-pound bag are effectively the workhorse sizes, and for typical soil they hold about the same amount, which is why so many stores treat them as interchangeable. The 1 cubic foot bag is the next step up and is common for premium or screened topsoil. The 1.5 and 2 cubic foot bags are less common for plain topsoil and show up more often for garden soil blends, raised bed mixes, and compost, where buyers want to move more volume in fewer bags. Below is a quick reference for what each size holds and roughly weighs.
0.5 cu ft bag. Holds a half cubic foot, weighs roughly 25 to 35 pounds, and takes 54 to make a yard. Handy for small containers and top-ups.
0.75 cu ft bag. The standard size, weighs roughly 40 pounds, and takes 36 to make a yard. The one most stores stock.
1 cu ft bag. Weighs roughly 50 to 60 pounds, takes 27 to make a yard, and is common for screened or premium soil.
1.5 to 2 cu ft bag. Weighs 75 to 110 pounds, takes 14 to 18 to make a yard, and is heavy to lift solo. Often used for garden soil blends.
Whichever size you reach for, the cubic feet on the bag is the number that matters for planning, and matching it against your project volume is the whole job. The how much topsoil you need guide is the companion piece for working out that volume in the first place.
How big is a bag of topsoil?
A standard bag of topsoil is smaller than most people picture. A 0.75 cubic foot bag, once filled and settled, is roughly the size of a large duffel bag or a stuffed pillow, and it holds enough soil to cover about 3 square feet at 3 inches deep, or about 9 square feet spread just 1 inch deep. A 40-pound bag is the same rough footprint. These bags are easy to sling into a cart and stack in a trunk, which is exactly why they are convenient for small jobs and awkward for large ones.
To put the size in context, a single 0.75 cubic foot bag holds about 5.6 gallons of soil by volume, since there are about 7.48 gallons in a cubic foot. That is roughly enough to fill one large planter or a couple of medium pots. A 1 cubic foot bag holds about 7.5 gallons, and a 2 cubic foot bag about 15 gallons. Thinking in gallons can help if you are filling containers, because pots are often sized in gallons and you can match the bag to the pot without converting anything.
The physical size also drives the effort question. A 0.75 cubic foot bag at around 40 pounds is a comfortable one-person lift, while a 2 cubic foot bag at 100-plus pounds is a two-person job or a lot of dragging. When you are choosing a bag size, weigh the fewer-trips benefit of a big bag against the strain of lifting it, especially if you are carrying soil around the side of a house or up steps. Once your soil is in place, spreading and settling it evenly is its own task, and the topsoil weight guide covers how much a filled bag actually weighs at different moisture levels so you know what you are lifting.
Measure your area, then use the Dirt Calculator to get the volume and read it against the bag chart above. The how much topsoil you need guide walks through the same steps with worked examples.
How heavy is a bag of topsoil?
A bag of topsoil weighs anywhere from about 25 to 110 pounds depending on its size and how wet the soil is. A 40-pound bag weighs, as the name says, about 40 pounds, and it is the most common size you will lift. A 0.5 cubic foot bag runs roughly 25 to 35 pounds, a 0.75 cubic foot bag about 40 pounds, a 1 cubic foot bag around 50 to 60 pounds, and a 1.5 to 2 cubic foot bag well past 75 pounds and often over 100. Moisture pushes every one of these figures higher, because water is heavy and topsoil soaks it up.
The weight matters for two practical reasons. The first is loading and carrying. A trunk full of 36 bags for a single yard is well over half a ton of soil to lift twice, once into the car and once out, and that is worth knowing before you decide bags are the easy option. The second is that weight-labelled bags hide their volume, so a heavy bag is not necessarily a better deal. A 40-pound bag of wet, dense soil holds less actual volume than a 40-pound bag of dry, fluffy soil, so you can pay the same for less coverage without realizing it.
If your back is the limiting factor, the smaller bags are gentler but multiply the number of trips, while the larger bags mean fewer lifts but each one is a strain. Many people find the 0.75 cubic foot or 40-pound bag the sweet spot, heavy enough to move real volume but light enough to handle alone. For the full picture on how bag weight scales with moisture and soil type, and how it compares to the weight of a bulk yard, the how much does a yard of topsoil weigh guide lays it all out with a weight chart.
Bagged vs bulk topsoil: cost and effort compared
The real decision behind all this counting is whether to buy bags or order bulk, and it comes down to cost and effort at the volume you need. Bagged topsoil usually runs somewhere around 2 to 6 dollars per bag depending on size and quality, which works out to roughly 40 to 120 dollars per cubic yard once you account for the 27 to 36 bags a yard takes. Bulk topsoil, by contrast, often runs about 15 to 60 dollars per cubic yard delivered, so per unit of soil, bulk is usually the cheaper option once you get past a small amount.
The crossover point where bulk starts to win is usually somewhere around 10 to 12 bags, which is roughly a third of a yard. Below that, bags are convenient, there is no delivery minimum or fee, and you buy exactly what you need with no leftover pile. Above it, the per-bag cost, the lifting, and the pile of empty plastic all start to add up, and a bulk delivery that lands in one drop becomes both cheaper and easier. If your project needs a full yard or more, bulk is almost always the better call unless you have no way to receive a delivery.
Tip: If you need less than about a third of a yard, buy bags. If you need a full yard or more and can take a delivery, order bulk. Right in between, weigh the delivery fee against the cost and effort of hauling 10 to 25 bags yourself.
Effort is the other half of the comparison and it is easy to underestimate. A yard of bagged soil is 27 to 54 separate items to buy, load, drive, unload, carry, cut open, and empty, plus a stack of empty bags to dispose of. A yard of bulk soil is one pile dropped where the truck can reach, which you then move with a wheelbarrow. For most people the bulk pile is less total work per yard, though it does require somewhere for the truck to dump and a barrow to move it. To compare prices properly for your own area, the topsoil cost guide breaks down price per yard, ton, and bag, and the Dirt Calculator gives you the volume that both prices hang on.
How to work out how many bags you need
Figuring out your own bag count takes two steps: find the volume of soil your project needs, then divide by the size of the bag you plan to buy. The volume is the part worth getting right, because a small error in depth turns into a large error in the number of bags, and nobody wants to make a second trip.
Multiply the length by the width by the depth of your area, all in feet, to get cubic feet. For a 10 by 4 foot bed at 3 inches deep, that is 10 x 4 x 0.25 = 10 cubic feet. Remember to convert inches of depth to feet by dividing by 12, so 3 inches is 0.25 feet.
Take your cubic feet and divide by the cubic feet per bag. Ten cubic feet divided by 0.75 is about 14 standard bags, or divided by 1 is 10 large bags. Always round up to the next whole bag, since you cannot buy part of one.
Add about 10 percent for settling and uneven ground, then round up again. For the 14-bag example, buy 15 or 16 bags so you are not caught short if the soil settles or the bed is deeper in spots.
That three-step method works for any bag size and any area. If your volume comes out above roughly 20 to 25 bags, it is worth pausing to compare the total bag cost against a bulk delivery, because you may be near the point where bulk is cheaper and less work. To skip the arithmetic entirely, enter your length, width, and depth into the Dirt Calculator or the Topsoil Calculator, and it will give you the volume in both cubic feet and yards so you can read the bag count straight off the chart above.
Frequently asked questions
How many bags of topsoil are in a yard?
It depends on the bag size, because a cubic yard is 27 cubic feet. It takes about 36 of the common 0.75 cubic foot bags, 27 of the 1 cubic foot bags, 18 of the 1.5 cubic foot bags, or 54 of the small 0.5 cubic foot bags to make one cubic yard. For the 40-pound bag sold by weight, plan on roughly 36 bags per yard, since a 40-pound bag of typical topsoil holds close to 0.75 cubic feet. To get the count, just divide 27 by the cubic feet printed on the bag, and round up to whole bags for a real order.
How many 40 lb bags of topsoil equal 1 yard?
About 36 forty-pound bags equal one cubic yard of topsoil. A 40-pound bag holds roughly 0.75 cubic feet of typical soil, and since a cubic yard is 27 cubic feet, 27 divided by 0.75 gives 36 bags. That figure can climb if the soil is heavy and wet, because a 40-pound bag of dense soil holds less volume, closer to 0.5 or 0.6 cubic feet, which pushes the count toward 45 or more. For a real project, plan on 36 bags per yard and buy a couple extra so you do not run short and have to make another trip to the store.
How many cubic feet are in a bag of topsoil?
A bag of topsoil usually holds between 0.5 and 2 cubic feet, with 0.75 cubic feet being the most common size. Volume-labelled bags print the exact figure on the front, so you can read it directly. Weight-labelled bags, like the 40-pound bag, do not print a volume, but 40 pounds of typical topsoil works out to about 0.75 cubic feet. The cubic feet figure is the one that matters for planning, since it tells you how much space the soil actually fills, while the weight only tells you what you are lifting and can vary with how wet the soil is.
How many cubic yards are in a bag of topsoil?
A single bag holds only a small fraction of a cubic yard. A 0.75 cubic foot bag holds about 0.028 of a yard, a 1 cubic foot bag about 0.037 of a yard, and a large 2 cubic foot bag about 0.074 of a yard, still under a tenth. You get these numbers by dividing the bag’s cubic feet by 27, the number of cubic feet in a yard. Because each bag is such a small slice of a yard, you always need dozens of bags to match a bulk delivery, which is why bags suit small jobs and bulk suits large ones.
How many bags of topsoil come on a pallet?
Most pallets of topsoil hold between about 40 and 56 bags, with a pallet of standard 40-pound or 0.75 cubic foot bags often landing near 50. Pallets of larger 1.5 or 2 cubic foot bags hold fewer because each bag is bulkier. A pallet of roughly 50 standard bags works out to about 37 to 42 cubic feet of soil, which is around 1.4 to 1.5 cubic yards. Counts vary by brand and region, so check the number listed on the wrap or product page, but treating a pallet as roughly 50 bags and about 1.5 yards is a safe planning estimate.
How big is a bag of topsoil?
A standard 0.75 cubic foot bag of topsoil is about the size of a large duffel bag or a stuffed pillow once filled. It holds enough soil to cover roughly 3 square feet at 3 inches deep, or about 9 square feet at 1 inch deep, and it works out to about 5.6 gallons of soil by volume. A 1 cubic foot bag holds about 7.5 gallons, and a 2 cubic foot bag about 15 gallons. These bags are easy to fit in a cart or trunk, which makes them handy for small beds and containers but awkward once you need dozens of them for a larger area.
How heavy is a bag of topsoil?
A bag of topsoil weighs between about 25 and 110 pounds depending on its size and moisture. A 0.5 cubic foot bag runs roughly 25 to 35 pounds, a 0.75 cubic foot or 40-pound bag about 40 pounds, a 1 cubic foot bag around 50 to 60 pounds, and a 1.5 to 2 cubic foot bag well over 75 pounds. Wet soil weighs more than dry soil at the same volume because water fills the air spaces. A yard’s worth of bags is over half a ton of lifting, done twice when you load and unload, which is worth remembering before deciding bags are the easy route.
Is it cheaper to buy topsoil in bags or bulk?
Bulk topsoil is usually cheaper once you need more than about a third of a yard, roughly 10 to 12 bags. Bagged soil runs about 2 to 6 dollars a bag, which works out near 40 to 120 dollars per cubic yard, while bulk soil often runs about 15 to 60 dollars per yard delivered. Below the crossover point, bags win on convenience with no delivery fee or minimum. Above it, bulk wins on both price and effort, since a full yard of bags is 27 to 54 separate items to haul and empty. If you need a yard or more and can take a delivery, order bulk.
The quick version
A cubic yard of topsoil is 27 cubic feet, so it takes about 36 of the 0.75 cubic foot bags, 27 of the 1 cubic foot bags, 18 of the 1.5 cubic foot bags, or 54 of the small 0.5 cubic foot bags to make a yard. A 40-pound bag holds roughly 0.75 cubic feet, so plan on about 36 of those per yard too, a little more if the soil is dense and wet. A single bag holds only a small fraction of a yard, and a pallet of standard bags runs around 50 bags, or about 1.4 to 1.5 yards. For anything past about a third of a yard, bulk delivery is usually cheaper and less work than hauling dozens of bags.
