So, you need to know how many 2 cubic foot bags of material fit into one cubic yard. Here’s the quick answer: You need about 14 two-cubic-foot bags to equal one cubic yard. This is because a cubic yard holds 27 cubic feet of material, and each bag holds 2 cubic feet. When you divide 27 by 2, you get 13.5. Since you can’t buy half a bag, you always need to round up to the next whole bag, which is 14. Knowing this helps you figure out the right landscaping material quantity for your projects without buying too much or too little.

What is a Cubic Yard Anyway?
Let’s start with the basics. What exactly is a cubic yard?
Picture a large box. Now, imagine this box is exactly 3 feet long, 3 feet wide, and 3 feet high. The amount of space inside that box is one cubic yard.
Think of a standard doorway. It’s about 3 feet wide. So, a cubic yard is like a cube as wide as a doorway, as deep as a doorway, and as tall as a doorway. That’s a lot of space!
Knowing this helps you visualize the material you are buying, whether it’s soil, mulch, gravel, or compost. Materials like these are often sold in cubic yards, especially if you buy in bulk.
Figuring Out the Volume of a Cubic Yard
To compare a cubic yard to smaller bags, we need to use the same unit of measurement. Bags are usually measured in cubic feet. So, we need to turn a cubic yard into cubic feet.
Here is how you do that using a basic volume calculation formula:
Volume = Length × Width × Height
For a cubic yard, all sides are 3 feet.
Volume of a cubic yard = 3 feet × 3 feet × 3 feet
Let’s do the math step by step:
- 3 feet × 3 feet = 9 square feet
- 9 square feet × 3 feet = 27 cubic feet
So, one cubic yard is equal to 27 cubic feet. This cubic feet to cubic yard conversion is super important for figuring out how much material you need.
How Much Does One Bag Hold?
The bags we are talking about hold 2 cubic feet of material. This could be bags of soil, bags of mulch, bags of gravel, or other landscaping materials.
Each bag is a small part of a full cubic yard. We know a yard holds 27 cubic feet. We know a bag holds 2 cubic feet. Now we can figure out how many times that 2 cubic feet fits into 27 cubic feet.
Getting the Number of 2 Cu Ft Bags
Now for the main calculation. We want to know how many bags fit into one cubic yard.
Here is the simple math:
Total cubic feet in one yard / Cubic feet per bag = Number of bags
Using our numbers:
27 cubic feet / 2 cubic feet per bag = 13.5 bags
So, it takes 13 and a half of the 2-cubic-foot bags to make one full cubic yard.
What About That Half Bag?
You can’t just buy half a bag of soil or mulch from the store. Bags are sold as whole units.
This is a key part of determining material quantity. Whenever your calculation results in a fraction of a bag, you must round up to the next whole number.
In our case:
13.5 bags rounds up to 14 bags.
So, to get the amount of material equal to one cubic yard using 2 cu ft bags, you need to buy 14 bags. You will have a little bit left over from the 14th bag, but that’s much better than not having enough!
Calculating How Much Material You Need
Knowing how many bags are in a yard is step one. But how do you figure out how many cubic yards (or how many bags) you need for your specific project? This is where you calculate yard volume for your area.
You need to know the size of the area you want to cover and how deep you want the material to be.
Figuring Area Size
Most areas are square or rectangle shaped.
- For a square or rectangle: Measure the length and the width of the area in feet. Multiply length by width to get the area in square feet.
- Area = Length (feet) × Width (feet)
- Example: Your garden bed is 10 feet long and 5 feet wide. Area = 10 ft × 5 ft = 50 square feet.
- For a circle: Measure the distance from the center to the edge (this is the radius) in feet. Multiply the radius by itself, then multiply by the number Pi (about 3.14).
- Area = Pi (3.14) × Radius (feet) × Radius (feet)
- Example: Your tree ring is a circle with a radius of 4 feet. Area = 3.14 × 4 ft × 4 ft = 3.14 × 16 sq ft = 50.24 square feet.
- For odd shapes: Try to break the shape into smaller squares, rectangles, or circles. Calculate the area of each small shape and add them together.
Choosing the Right Depth
The depth you need depends on the material and what you are using it for.
- Mulch is often applied 2-4 inches deep.
- Soil depth depends on what you are planting, maybe 4-8 inches or more.
- Gravel depth depends on the use, maybe 2-6 inches for a walkway or driveway base.
You must measure the depth in feet to match the other measurements.
- 1 inch = 1/12 of a foot (about 0.083 feet)
- 2 inches = 2/12 = 1/6 of a foot (about 0.167 feet)
- 3 inches = 3/12 = 1/4 of a foot (0.25 feet)
- 4 inches = 4/12 = 1/3 of a foot (about 0.333 feet)
- 6 inches = 6/12 = 1/2 of a foot (0.5 feet)
- 8 inches = 8/12 = 2/3 of a foot (about 0.667 feet)
- 12 inches = 1 foot
It’s usually easiest to convert inches to feet by dividing the number of inches by 12.
Calculating the Total Cubic Feet Needed
Now that you have the area in square feet and the depth in feet, you can find the total volume needed in cubic feet.
Total Volume (cubic feet) = Area (square feet) × Depth (feet)
-
Example using the rectangular garden bed: Area is 50 square feet. You want 6 inches of soil. 6 inches is 0.5 feet.
- Total Volume = 50 sq ft × 0.5 ft = 25 cubic feet.
-
Example using the circular tree ring: Area is about 50.24 square feet. You want 3 inches of mulch. 3 inches is 0.25 feet.
- Total Volume = 50.24 sq ft × 0.25 ft = 12.56 cubic feet.
This is how you calculate yard volume needed for your project in cubic feet. This volume calculation formula is very useful.
Converting Total Cubic Feet to Cubic Yards (and Bags!)
Once you have the total cubic feet needed, you can easily figure out how many cubic yards or how many bags you need.
To find Cubic Yards needed:
Use the cubic feet to cubic yard conversion we learned: Divide total cubic feet by 27.
Cubic Yards Needed = Total Cubic Feet Needed / 27
-
Garden bed example: You need 25 cubic feet.
- Cubic Yards Needed = 25 cu ft / 27 cu ft/yard = 0.926 cubic yards.
- You would likely order 1 cubic yard if buying in bulk.
-
Tree ring example: You need 12.56 cubic feet.
- Cubic Yards Needed = 12.56 cu ft / 27 cu ft/yard = 0.465 cubic yards.
- You would likely order 0.5 cubic yards if buying in bulk, or perhaps 1 yard if that’s the minimum.
To find the Number of 2 Cu Ft Bags needed:
Divide the total cubic feet needed by the volume of one bag (2 cubic feet).
Number of Bags Needed = Total Cubic Feet Needed / 2 Cu Ft per Bag
-
Garden bed example: You need 25 cubic feet.
- Number of Bags = 25 cu ft / 2 cu ft/bag = 12.5 bags.
- Round up! You need 13 bags.
-
Tree ring example: You need 12.56 cubic feet.
- Number of Bags = 12.56 cu ft / 2 cu ft/bag = 6.28 bags.
- Round up! You need 7 bags.
This process helps you with determining material quantity accurately, whether you are trying to figure out bags of soil per yard or gravel bag to yard conversion for a specific area.
Using a Mulch Bag Coverage Calculator Idea
Many stores or websites have tools that act like a mulch bag coverage calculator. These tools do the math for you. You usually type in:
- The length of your area.
- The width of your area.
- The depth you want.
- The size of the bag you plan to buy (like 2 cu ft).
The calculator then tells you how many bags you need. This is based on the same volume calculation formula we just used. It figures out the total volume in cubic feet or cubic yards and then divides by the bag size, remembering to round up.
While calculators are handy, knowing how to do the math yourself means you can double-check their numbers or figure things out on the spot.
Bulk vs Bagged Materials
When you need landscaping material quantity, you usually have two main choices: buying in bulk or buying in bags. Both have good and bad points.
Buying in Bags (like 2 cu ft bags)
- Pros:
- Easy to transport small amounts in a car.
- Simple to handle; you can move one bag at a time.
- Good for small projects or touching up existing areas.
- Less mess in your yard compared to a big pile.
- Cons:
- More expensive per cubic foot or yard compared to bulk.
- Requires a lot of lifting and opening many bags for larger jobs.
- Bags create waste (plastic).
- Can be harder to get large amounts quickly; you need to buy many bags.
Buying in Bulk (by the cubic yard)
- Pros:
- Much cheaper per cubic foot or yard.
- Delivered right to your driveway or a spot in your yard.
- Less plastic waste.
- Fastest way to get a lot of material.
- Cons:
- Needs a way to move the material from the pile (wheelbarrow, shovel).
- Can be messy; you have a large pile sitting there.
- Requires a truck or delivery service; you can’t just pick it up in a small car.
- Might be more than you need for very small jobs (minimum order might be 0.5 or 1 cubic yard).
Thinking about bulk vs bagged materials involves considering the size of your project, your budget, and how you plan to move the material.
Calculating for Other Bag Sizes
The same method works for any bag size. Whether you need to figure out gravel bag to yard conversion for 0.5 cu ft bags or mulch bag coverage for 3 cu ft bags, the steps are the same.
- Find the total cubic feet needed for your project area (Length × Width × Depth in feet).
- Find the volume of one bag in cubic feet.
- Divide the total cubic feet needed by the volume of one bag.
- Round the result up to the nearest whole number.
-
Example: How many 0.75 cu ft bags in a yard?
- One yard = 27 cubic feet.
- Bag size = 0.75 cubic feet.
- Calculation: 27 / 0.75 = 36 bags.
- You need 36 bags.
-
Example: How many 3 cu ft bags in a yard?
- One yard = 27 cubic feet.
- Bag size = 3 cubic feet.
- Calculation: 27 / 3 = 9 bags.
- You need 9 bags.
See how knowing the cubic feet to cubic yard conversion (1 yard = 27 cu ft) makes these calculations easy?
Practical Tips for Determining Material Quantity
- Measure Carefully: Double-check your length, width, and depth measurements. Small errors can mean you buy too much or too little.
- Account for Settling: Materials like mulch or soil can settle over time. You might want to add a little extra to your depth measurement, especially for mulch, which breaks down. For example, if you want 3 inches of settled mulch, start with 4 inches.
- Consider Waste: Some material might be lost or wasted during spreading. It’s often wise to round up or buy a little extra, especially for loose materials.
- Think About Delivery/Transport: If buying bulk, where will they dump it? Can you easily move it from there? If buying bags, do you have a vehicle that can carry the weight and number of bags? A 2 cu ft bag can weigh 20-50 pounds or more depending on the material and moisture! 14 bags could weigh over 500 pounds.
- Check Bag Weight: While bags are sold by volume (cubic feet), their weight can vary a lot. Wet soil weighs much more than dry mulch. This is important for transport.
- Use Online Calculators: While knowing the math is good, online tools can be fast. Just make sure you enter your numbers correctly. Many garden supply stores have these on their websites.
A Quick Summary Table
Here’s a handy table showing the conversion for common bag sizes into one cubic yard.
| Bag Size (Cubic Feet) | Calculation (27 / Bag Size) | Number of Bags Needed (Rounded Up) |
|---|---|---|
| 0.5 cu ft | 27 / 0.5 = 54 | 54 bags |
| 0.75 cu ft | 27 / 0.75 = 36 | 36 bags |
| 1 cu ft | 27 / 1 = 27 | 27 bags |
| 1.5 cu ft | 27 / 1.5 = 18 | 18 bags |
| 2 cu ft | 27 / 2 = 13.5 | 14 bags |
| 3 cu ft | 27 / 3 = 9 | 9 bags |
| 4 cu ft | 27 / 4 = 6.75 | 7 bags |
This table is a quick guide for bags of soil per yard, mulch bag coverage, gravel bag to yard conversion, and more.
Making Sense Of Volume Conversions
Why do we use different units like cubic feet and cubic yards? It’s often about what makes the most sense for the amount of material.
- Small projects or retail sales use bags (cubic feet). It’s easier to think about a few bags.
- Large projects or wholesale sales use cubic yards (bulk). It’s easier to think about a few yards for a big garden bed or driveway.
Being able to switch between these units using the cubic feet to cubic yard conversion (1 yard = 27 cu ft) lets you compare prices (price per bag vs. price per yard) and figure out exactly how much material you need for any size job. This is key to determining material quantity efficiently.
Common Materials and Their Calculations
The calculation is the same no matter the material – soil, mulch, gravel, compost, sand, etc. What does change is the weight of the material and sometimes the recommended depth.
- Bags of Soil per Yard: Soil is dense and heavy. 14 bags of soil (a yard) will be quite heavy. Recommended depth depends on planting needs.
- Mulch Bag Coverage: Mulch is lighter than soil or gravel. Recommended depth is usually 2-4 inches for weed control and moisture retention. A mulch bag coverage calculator uses this depth.
- Gravel Bag to Yard Conversion: Gravel is very heavy. 14 bags of gravel (a yard) is a lot of weight. Recommended depth depends on the use (pathway, base layer, drainage).
Always double-check the recommended depth for the specific material you are using and its purpose.
Calculating For Multiple Yards
What if your project needs more than one cubic yard?
Let’s say you calculated that you need 50 cubic feet of material.
Method 1: Convert total cubic feet to yards first
- Yards needed = 50 cu ft / 27 cu ft/yard = 1.85 cubic yards.
- If buying in bulk, you’d likely order 2 cubic yards.
- If buying 2 cu ft bags:
- Number of bags = 1.85 yards × 14 bags/yard (since 1 yard is about 14 bags) = 25.9 bags.
- Round up! You need 26 bags.
Method 2: Convert total cubic feet directly to bags
- Number of bags = Total Cubic Feet Needed / Cu Ft per Bag
- Number of bags = 50 cu ft / 2 cu ft/bag = 25 bags.
- Round up! You need 25 bags. (Wait, this is different from Method 1!)
What happened? Method 1 used the rounded bag number per yard before multiplying. Method 2 is more accurate because it uses the exact total cubic feet needed before dividing by the bag size and rounding up only at the end.
Always use Method 2: Calculate the total cubic feet needed first, then divide by the bag size, and then round up.
-
Example: Need 50 cu ft. Bags are 2 cu ft.
- 50 / 2 = 25.
- Do you need 25 bags exactly? No, if the calculation wasn’t a whole number, you’d round up. In this case, it is a whole number, so you need 25 bags.
-
Example: Need 51 cu ft. Bags are 2 cu ft.
- 51 / 2 = 25.5.
- Round up! You need 26 bags.
This second method is the most accurate way of determining material quantity when buying in bags.
Wrapping Up the Calculation
So, to come back to our original question, “How Many 2 Cu Ft Bags In A Yard?”.
- A cubic yard is 27 cubic feet.
- A bag holds 2 cubic feet.
- 27 / 2 = 13.5.
- You cannot buy half a bag.
- You must round up to 14 bags.
This calculation is the base for figuring out how many 2 cu ft bags you need for any size project.
By calculating the volume of your area in cubic feet (Length × Width × Depth), and then dividing that total by 2 (the size of the bag), and always rounding up, you can accurately determine your landscaping material quantity. This saves you time, money, and extra trips to the store.
Whether you’re spreading bags of soil per yard, covering a bed with mulch using a mulch bag coverage calculation method, or converting gravel bag to yard for a path, the core math stays the same. Now you have the tools to figure out exactly how much you need!
Frequently Asked Questions
h4 Is a cubic yard always 27 cubic feet?
h5 Yes, by definition, one cubic yard is always equal to 27 cubic feet. This is a standard unit conversion.
h4 Why do I need to round up the number of bags?
h5 You round up because you can only buy full bags. If your calculation shows you need a part of a bag (like 13.5 bags), you must buy the next whole bag to make sure you have enough material (so, 14 bags).
h4 Can I mix different bag sizes in my calculation?
h5 It’s best to figure out how many bags of one specific size you need. Calculate the total cubic feet needed for your area, then divide that by the size of the bag you plan to buy (whether it’s 2 cu ft, 3 cu ft, etc.), and round up.
h4 Does the type of material change the calculation for bags per yard?
h5 The number of bags per cubic yard based on volume (like 14 bags for 2 cu ft bags) is the same no matter the material. One cubic foot of soil takes up the same space as one cubic foot of mulch. However, the weight of the bags and the best depth to use can vary a lot depending on the material (soil, mulch, gravel).
h4 How can I estimate how much a cubic yard looks like?
h5 Imagine a cube that is 3 feet wide, 3 feet deep, and 3 feet high. That’s a cubic yard. Many landscape supply places have a display area where they show you what 1 cubic yard of different materials looks like in a box or pile. This helps you visualize the amount before you order bulk or buy many bags.
