How much does a yard of topsoil cover? The honest answer is that a single cubic yard covers a lot of ground spread thin and very little spread deep, so the number only means something once you fix a depth. At a thin 1 inch, one cubic yard of topsoil covers about 324 square feet. At the 3 inches most people use for a new lawn or a garden bed, that same yard covers about 108 square feet. Go to 4 inches and it drops to roughly 81 square feet, and at a deep 6 inches a yard covers only about 54 square feet. So the coverage of a yard is not one figure but a sliding scale that depends entirely on how thickly you lay it. That is the whole trick to estimating topsoil: pick your depth first, then the coverage falls out of it. This guide gives you clear coverage numbers for a cubic yard, a ton, a 40-pound bag, and a single cubic foot, a full coverage chart in square feet, and the simple formula behind every figure so you can work out your own project in your head. It also answers the questions people search most, from how far a yard really goes to how many yards you need for a 1,000 or 5,000 square foot area, so whatever size your project is you can turn it into an order with confidence.
If you know the square footage you want to cover and the depth you want, skip the mental math and drop your numbers into the Dirt Calculator or the Topsoil Calculator. They turn your area and depth straight into the cubic yards you need, and the coverage figures below tell you the reasoning behind the answer.

How much area does a yard of topsoil cover?
A cubic yard of topsoil covers about 108 square feet at a standard 3 inches deep, roughly 81 square feet at 4 inches, and about 162 square feet at 2 inches. Spread thin at 1 inch for topdressing a lawn, one yard reaches around 324 square feet, and laid deep at 6 inches for a raised bed it covers only about 54 square feet. If you want a single figure to carry in your head, remember that one yard covers roughly 100 square feet at 3 inches, which is the depth most home projects land on.
The reason there is no single coverage number is that a cubic yard is a fixed volume of soil, 27 cubic feet, and coverage is that volume spread out over an area. The thinner you spread it, the more ground it reaches. The deeper you pile it, the less area it covers. This is why the honest answer to how much does a yard of topsoil cover always starts with a question back: at what depth? A yard that covers a small bed at 4 inches will top-dress a whole side yard at half an inch, and both answers are correct for the same pile of soil.
For quick planning it helps to anchor on the 3-inch figure of about 108 square feet, because 3 inches is a common depth for laying new lawn soil, filling a bed, or leveling a patchy area. From there you can scale in your head: double the depth to 6 inches and the coverage roughly halves to 54 square feet, or cut the depth to 1.5 inches and the coverage roughly doubles to 216 square feet. To skip the arithmetic entirely, the Dirt Calculator turns any area and depth into a yardage in one step.
Why depth changes everything about coverage
Depth is the single most important number in any topsoil coverage estimate, and it is the one people most often forget to fix before they order. Two projects that both need to cover 200 square feet can call for wildly different amounts of soil depending on whether that area is being top-dressed at half an inch or filled at 6 inches. Get the depth right and your order lands on target. Get it wrong and you either run short halfway through or end up with a spare pile in the driveway.
The relationship is inverse and simple: as depth goes up, coverage goes down in direct proportion. Doubling the depth halves the coverage, and halving the depth doubles the coverage. A cubic yard that covers 108 square feet at 3 inches covers only 54 square feet at 6 inches, but stretches to 216 square feet at 1.5 inches. Nothing about the soil changes, only how thickly you are laying it. This is why a supplier cannot tell you how many yards you need until you tell them how deep you are going.
Different jobs call for different depths, which is exactly why coverage shifts so much from project to project. Topdressing an established lawn wants only a quarter inch to half an inch, so a yard goes a very long way. Laying soil for new grass seed usually wants 2 to 3 inches. Filling a garden bed or a raised bed often wants 4 to 8 inches so roots have room. Leveling a low spot depends on how low the spot is. Because the right depth depends on the job, it pays to settle that first, and the guide on how deep topsoil should be for different projects walks through sensible depths for lawns, beds, and gardens before you convert anything to coverage.
The formula behind topsoil coverage
Every coverage figure in this guide comes from one small formula, and once you have it you never need a chart again. A cubic yard is 27 cubic feet. To find how many square feet that covers at a given depth, you divide the volume by the depth expressed in feet. Because there are 12 inches in a foot, this works out to a clean shortcut: the square feet a cubic yard covers equals 324 divided by the depth in inches.
The rule to remember: square feet covered by one cubic yard = 324 ÷ depth in inches. So at 3 inches, 324 ÷ 3 = 108 square feet. At 4 inches, 324 ÷ 4 = 81 square feet. At 1 inch, 324 ÷ 1 = 324 square feet.
Where does the 324 come from? A cubic yard holds 27 cubic feet, and each square foot of ground covered 1 inch deep uses one twelfth of a cubic foot of soil. Multiply 27 cubic feet by 12 and you get 324 square feet of coverage at 1 inch deep. From there, every other depth is just that 324 divided by however many inches deep you go. It is the same math whether you are covering a flower bed or an entire back lawn, which is why this one number does so much work.
The formula also runs in reverse, which is how you size an order. If you know the area you want to cover and the depth, multiply the square feet by the depth in inches, then divide by 324, and you have the cubic yards you need. For a 500 square foot area at 3 inches, that is 500 times 3, which is 1,500, divided by 324, giving about 4.6 cubic yards. The Dirt Calculator and the Cubic Yard Calculator run this exact calculation for you, but knowing the formula lets you sanity-check any quote on the spot.
Topsoil coverage chart by yards and depth
The chart below shows how many square feet different amounts of topsoil cover at common depths. Read down the left for your depth, then across to the amount you are buying, and the cell shows the area it covers in square feet. Every figure comes straight from the 324-divided-by-depth rule, scaled up for larger loads, so you can use it to size almost any project at a glance.
| Depth | 1 yard | 3 yards | 5 yards | 10 yards |
|---|---|---|---|---|
| 1 inch | ~324 sq ft | ~972 sq ft | ~1,620 sq ft | ~3,240 sq ft |
| 2 inches | ~162 sq ft | ~486 sq ft | ~810 sq ft | ~1,620 sq ft |
| 3 inches | ~108 sq ft | ~324 sq ft | ~540 sq ft | ~1,080 sq ft |
| 4 inches | ~81 sq ft | ~243 sq ft | ~405 sq ft | ~810 sq ft |
| 5 inches | ~65 sq ft | ~195 sq ft | ~324 sq ft | ~648 sq ft |
| 6 inches | ~54 sq ft | ~162 sq ft | ~270 sq ft | ~540 sq ft |
A couple of patterns are worth noticing. Reading down any column shows how fast coverage falls as depth grows: one yard covers six times as much ground at 1 inch as it does at 6 inches. Reading across any row shows the coverage simply scaling with the load, so 10 yards covers ten times what a single yard does. If your depth is not on the chart, fall back to the formula: 324 divided by your depth in inches gives the coverage for one yard, and you multiply from there. To match your own area to these numbers, run it through the Dirt Calculator first.
It also helps to translate the square footage into shapes you can picture. The 108 square feet a single yard covers at 3 inches is close to a 10 foot by 10 foot patio, so if your bed is about that size you need one yard for 3 inches of soil. Five yards at 3 inches covers 540 square feet, roughly a one-car driveway and a half, and ten yards at that depth covers 1,080 square feet, about the footprint of a small house. Holding the picture in your head next to the number is the fastest way to catch an order that is obviously too small or too large before it is placed.
How much area does a cubic foot of topsoil cover?
A single cubic foot of topsoil covers about 4 square feet at 3 inches deep, 6 square feet at 2 inches, and 12 square feet spread 1 inch thin. At the deeper 4 inches it reaches only about 3 square feet. The math mirrors the yard formula on a smaller scale: one cubic foot covers 12 square feet at 1 inch, so you divide 12 by the depth in inches for any other depth.
This cubic-foot figure is the one that matters when you are working with bagged soil or filling a small container, because bags are labeled in cubic feet rather than yards. If you buy a 1 cubic foot bag and want to fill a planter box 3 inches deep, that bag will cover about 4 square feet, which is roughly a 2 foot by 2 foot area. Knowing this saves you from buying five bags for a job that needs two, or the reverse, showing up one bag short for a bed you thought was small.
It also helps to see how the cubic foot ladders up to the yard. Since a cubic yard is 27 cubic feet, and one cubic foot covers 12 square feet at 1 inch, 27 of them cover 324 square feet at that depth, which is exactly the yard figure. Everything ties back to the same rule. If you are trying to decide between buying a few bags or ordering bulk, the guide on how many bags of topsoil make up a yard lays the two options side by side so you can compare cost and effort.
How much area does a 40 lb bag of topsoil cover?
A standard 40-pound bag of topsoil holds about 0.75 cubic feet of soil, and it covers roughly 3 square feet at 3 inches deep. Spread thinner at 1 inch it reaches about 9 square feet, and at 2 inches it covers about 4.5 square feet. At a deep 4 inches, one bag covers only about 2 square feet. So a 40-pound bag, despite feeling heavy to carry, does not cover much ground once you lay it at a normal planting depth.
Those numbers come from the same formula scaled to the bag size. A 0.75 cubic foot bag covers 9 square feet at 1 inch, because 0.75 cubic feet times 12 equals 9. Divide that 9 by your depth in inches to get the coverage at any other depth. This is why the 40-pound bag is convenient for a small raised bed or a container but quickly becomes expensive and tiring for anything larger, since you would need a stack of them to cover even a modest bed at a useful depth.
To put the bag in perspective against bulk soil, it takes about 36 of these 0.75 cubic foot bags to equal one cubic yard, and one yard covers 108 square feet at 3 inches. So 36 bags cover that same 108 square feet, which works out to that 3 square feet per bag. If you find yourself needing more than roughly ten to fifteen bags for a project, bulk delivery is almost always cheaper and far less work. The number of bags a job takes is worked through in detail in the guide on bags of topsoil in a yard, and the Topsoil Calculator will tell you the equivalent bulk volume.
If you are still working out the total amount for your project rather than the coverage per bag, start with how much topsoil you need and confirm the figure in the Dirt Calculator before you buy a single bag.
How much area does a ton of topsoil cover?
A ton of topsoil covers roughly 70 to 90 square feet at 3 inches deep, or about 210 to 270 square feet spread 1 inch thin. The range exists because a ton is a weight, not a volume, and how much volume a ton gives you depends on how wet and dense the soil is. A ton of topsoil usually works out to somewhere between about 0.7 and 0.9 of a cubic yard, so its coverage lands a little below what a full cubic yard covers.
This is where buying by the ton gets tricky compared with buying by the cubic yard. When you order by volume, a cubic yard is always a cubic yard and always covers about 108 square feet at 3 inches, no matter the moisture. When you order by weight, a ton of wet, heavy soil holds less actual volume than a ton of dry soil, so it covers less ground. If a supplier quotes you tons, it is worth converting to cubic yards first so you can check the coverage against the area you actually need to fill.
For a working estimate, treat a ton as covering about the same as three-quarters to nine-tenths of a yard at your chosen depth. So at 3 inches, a ton covers roughly 80 square feet, and at 2 inches roughly 120 square feet. If your project is quoted in tons and you want to translate it into yards and coverage cleanly, the companion guide on how much a yard of topsoil weighs covers the weight-to-volume conversion in full, and the Dirt Calculator will give you the volume for your area so you can compare the two on equal footing.
One more reason the ton figure is slippery: the same ton covers noticeably less ground after a wet spell than it does in dry weather, purely because water adds weight without adding coverage. If two suppliers both quote a ton and one has soil that has been sitting uncovered through rain, you are paying the same price for less actual dirt and less coverage. This is the strongest argument for buying topsoil by the cubic yard whenever you have the choice, since a yard covers the same 108 square feet at 3 inches whether the soil is soaked or bone dry.
How far does a yard of topsoil really go?
How far a yard of topsoil goes is one of those questions where the gut answer and the real answer often disagree. People tend to picture a cubic yard as a big pile, which it is, roughly a cube 3 feet on each side, and assume it will cover a large area. Then they spread it at a proper depth and are surprised how quickly it runs out. A yard is a lot of soil to move but a modest amount of coverage once it is laid at any real thickness.
The clearest way to picture it is by depth. At 1 inch, a yard covers a 324 square foot area, which is roughly an 18 foot by 18 foot square, so it top-dresses a decent stretch of lawn. At 3 inches, that same yard covers only 108 square feet, about a 10 foot by 10 foot square, enough for one modest bed or a small patch of new lawn. At 6 inches, it covers just 54 square feet, barely more than a 7 foot by 7 foot square, which is why filling raised beds eats through yards fast. Same pile of soil, very different reach.
This gap between how big a yard looks and how far it goes is the number one reason people under-order. A homeowner sees a yard delivered, thinks it looks like plenty, and orders one when the job actually needs three. The fix is to always convert your area and depth into a volume before you buy rather than eyeballing the pile. Figuring how far your specific yardage will go is exactly what the how much topsoil do I need guide is built for, and the Dirt Calculator removes the guesswork so the pile that arrives matches the job in front of you.
How much topsoil do I need for 1,000 square feet?
Covering 1,000 square feet takes about 3.1 cubic yards at 1 inch deep, roughly 6.2 yards at 2 inches, about 9.3 yards at 3 inches, and around 12.3 yards at 4 inches. So a 1,000 square foot area is not a small order once you get past a thin topdressing. At the popular 3-inch depth for new lawn soil, plan for a little over 9 cubic yards, which is a full delivery in most trucks.
The math is the reverse formula at work: multiply the 1,000 square feet by the depth in inches, then divide by 324. At 3 inches that is 1,000 times 3, which is 3,000, divided by 324, giving about 9.3 cubic yards. It is worth rounding up rather than down, both because soil settles as it beds in and because you would rather have a little left over than stop the job to order more. Adding about 10 percent to your figure is a sensible cushion, which would take that 9.3 yards to roughly 10.2 yards for a 1,000 square foot lawn at 3 inches.
A 1,000 square foot project is a common size for a front lawn renovation or a large bed, and it sits right at the point where bulk delivery clearly beats bags. Buying that much soil in 40-pound bags would mean hauling well over 300 bags, so bulk is the obvious choice. Before you place the order, plug 1,000 square feet and your chosen depth into the Topsoil Calculator to confirm the yardage, and check the coverage chart above so you understand how the depth you pick drives the total.
How many yards of topsoil for 5,000 square feet?
Covering 5,000 square feet takes about 15.4 cubic yards at 1 inch deep, roughly 30.9 yards at 2 inches, about 46.3 yards at 3 inches, and around 61.7 yards at 4 inches. This is large-project territory, the size of a sizable lawn or a small field, and the yardages climb fast with depth. At 3 inches you are looking at more than 46 cubic yards, which is several truckloads and worth planning carefully with your supplier.
Because the numbers are big, depth matters more than ever on a project this size. Dropping from 3 inches to 2 inches on 5,000 square feet saves you about 15 cubic yards, which is a meaningful chunk of cost and a truckload of material. This is why, for large lawn areas that only need soil to establish grass rather than to fill, many people choose a shallower 1 to 2 inch layer over existing ground rather than a full 3 to 4 inches. The right call depends on what is underneath and what you are growing, which the guide on choosing the right topsoil depth helps you decide.
For a 5,000 square foot job the formula is the same as any other: multiply 5,000 by your depth in inches and divide by 324. At 2 inches that is 5,000 times 2, which is 10,000, divided by 324, giving about 30.9 cubic yards. With orders this large, it is wise to confirm the total with the Dirt Calculator and then talk to your supplier about delivery, since a job of this scale usually arrives across multiple loads and a small error in depth translates into whole extra truckloads of soil and cost.
How many yards of topsoil per square foot?
Turning the coverage question around, one square foot of ground needs about 0.0031 cubic yards of topsoil at 1 inch deep, roughly 0.0093 yards at 3 inches, and about 0.0123 yards at 4 inches. These are tiny fractions because a square foot is a tiny area next to a cubic yard, but they are useful multipliers: once you have the per-square-foot figure for your depth, you multiply by your total area and you have the yardage.
The cleanest way to hold this in your head is through the coverage figures you already have. At 3 inches, one cubic yard covers 108 square feet, so each square foot uses 1 divided by 108, which is about 0.0093 of a yard. At 1 inch, a yard covers 324 square feet, so each square foot uses 1 divided by 324, about 0.0031 of a yard. Whatever depth you choose, the per-square-foot yardage is simply 1 divided by the coverage a yard gives at that depth.
In practice, most people find it easier to work from coverage than from these small fractions, because multiplying by 0.0093 in your head is awkward. The fractions matter mainly when you are building your own quick estimate or checking a calculator’s output for a large, oddly shaped area. For everyday projects, the coverage chart and the 324 rule get you there faster. Either way, the Cubic Yard Calculator and the Dirt Calculator handle the fractions cleanly so you can focus on getting your area and depth right.
How to work out coverage for your own project
You can size any topsoil job in three short steps, and the whole thing rests on the 324 rule from earlier. The only inputs you need are the area you want to cover and the depth you want to lay it at, both of which you decide before you order.
Multiply length by width for a rectangle, or break an odd shape into rectangles and add them up. A bed 12 feet long and 8 feet wide is 96 square feet. For a lawn, pace it out or measure the boundaries and multiply.
Use about 1 inch for topdressing an existing lawn, 2 to 3 inches for laying new grass seed, and 4 to 8 inches for filling beds or raised beds. Depth drives everything, so choose it deliberately rather than guessing.
Multiply your square feet by the depth in inches, then divide by 324 to get cubic yards. For that 96 square foot bed at 4 inches, that is 96 times 4, which is 384, divided by 324, giving about 1.2 cubic yards. Round up slightly to allow for settling.
That is the entire method, and it works for a window box or a whole back lawn. The step where errors creep in is the depth, because a small change there swings the total more than most people expect: laying 4 inches instead of 3 across a large area can add a third to your order. Because of that, it is worth confirming your final figure with the Dirt Calculator or the Topsoil Calculator before you buy, especially on bigger jobs where a wrong depth turns into extra truckloads. Get the area and depth right, apply the 324 rule, and the coverage question answers itself.
Frequently asked questions
How much does a yard of topsoil cover?
A cubic yard of topsoil covers about 108 square feet at 3 inches deep, which is the most common depth for lawns and beds. Spread thinner at 1 inch it reaches around 324 square feet, at 2 inches about 162 square feet, and at 4 inches roughly 81 square feet. Laid deep at 6 inches, a yard covers only about 54 square feet. There is no single coverage number because a yard is a fixed volume of soil, and how far it goes depends entirely on the depth you spread it. Fix your depth first, then use 324 divided by the depth in inches to get the coverage for one yard.
How many square feet does a yard of topsoil cover at 3 inches?
At 3 inches deep, one cubic yard of topsoil covers about 108 square feet, which is roughly a 10 foot by 10 foot square. Three inches is a common depth for laying soil under new grass seed or filling a garden bed, so this is the figure most home projects use. If you go shallower to 2 inches, the same yard covers about 162 square feet, and if you go deeper to 4 inches it covers about 81 square feet. The rule behind all of these is 324 divided by the depth in inches, so at 3 inches that is 324 divided by 3, giving 108 square feet per cubic yard.
How many square feet does a 40 lb bag of topsoil cover?
A 40-pound bag of topsoil holds about 0.75 cubic feet and covers roughly 3 square feet at 3 inches deep. Spread thinner at 1 inch it reaches about 9 square feet, at 2 inches about 4.5 square feet, and at a deep 4 inches only about 2 square feet. Despite the weight, a single bag does not cover much once you lay it at a normal planting depth. It takes around 36 of these bags to equal one cubic yard, so if your project needs more than ten or fifteen bags, bulk delivery is usually cheaper and far less work than hauling and emptying stacks of bags.
How much area does a ton of topsoil cover?
A ton of topsoil covers roughly 70 to 90 square feet at 3 inches deep, or about 210 to 270 square feet spread 1 inch thin. The range exists because a ton is a weight, and how much volume it gives you depends on moisture and density. A ton usually works out to about 0.7 to 0.9 of a cubic yard, so it covers a little less ground than a full yard. If your supplier quotes tons, convert to cubic yards first so you can check the coverage against your actual area, since a ton of wet, heavy soil holds less volume, and therefore covers less, than a ton of dry soil.
How many yards of topsoil do I need for 1,000 square feet?
For 1,000 square feet you need about 3.1 cubic yards at 1 inch deep, roughly 6.2 yards at 2 inches, about 9.3 yards at 3 inches, and around 12.3 yards at 4 inches. At the common 3-inch depth for new lawn soil, plan for a little over 9 cubic yards. The math is your area times the depth in inches, divided by 324, so 1,000 times 3 divided by 324 gives about 9.3 yards. It is worth adding roughly 10 percent to allow for settling, which would take that to about 10 yards. A project this size is well into bulk-delivery territory rather than bags.
How many yards of topsoil for 5,000 square feet?
Covering 5,000 square feet takes about 15.4 cubic yards at 1 inch deep, roughly 30.9 yards at 2 inches, about 46.3 yards at 3 inches, and around 61.7 yards at 4 inches. This is a large project, so depth has a big effect on cost: dropping from 3 inches to 2 inches saves about 15 yards of soil. The formula is 5,000 times the depth in inches divided by 324, so at 2 inches that is 5,000 times 2 divided by 324, giving about 30.9 yards. Orders this large usually arrive across several truckloads, so confirm the total and arrange delivery with your supplier in advance.
How far does a yard of topsoil go?
A cubic yard of topsoil goes further than people expect at thin depths and less far than they expect at deep ones. At 1 inch it covers about 324 square feet, roughly an 18 foot by 18 foot square. At 3 inches it covers only about 108 square feet, a 10 foot by 10 foot square. At 6 inches it covers just 54 square feet. A yard looks like a big pile, about a 3-foot cube, which is why so many people under-order, assuming it will stretch further than it does once laid at a real depth. Always convert your area and depth to a volume before buying rather than judging by the size of the pile.
How many yards of topsoil per square foot?
One square foot of ground needs about 0.0031 cubic yards of topsoil at 1 inch deep, roughly 0.0093 yards at 3 inches, and about 0.0123 yards at 4 inches. These are small fractions because a square foot is tiny next to a cubic yard. The easiest way to find the figure is to take the coverage a yard gives at your depth and divide 1 by it: at 3 inches a yard covers 108 square feet, so each square foot uses 1 divided by 108, about 0.0093 of a yard. For everyday planning, working from coverage figures is faster than multiplying these small fractions by hand.
The quick version
A cubic yard of topsoil covers about 108 square feet at 3 inches deep, 162 square feet at 2 inches, 81 square feet at 4 inches, and around 324 square feet spread thin at 1 inch. The rule behind every figure is simple: square feet covered by one yard equals 324 divided by the depth in inches. A cubic foot covers about 4 square feet at 3 inches, a 40-pound bag about 3 square feet, and a ton roughly 70 to 90 square feet. To size a project, multiply your area by the depth in inches and divide by 324 to get the cubic yards, then round up a little for settling. Depth drives everything, so pick it before you order.
