A ton of pea gravel typically covers an area of 100 square feet at a depth of two inches. This is equivalent to approximately five buckets of gravel spread over the same space. Depending on the size of the gravel, the coverage can vary, but this is a good approximation for standard pea gravel with a diameter of around ¼ inch.
Generally, the larger the gravel, the less coverage a ton will provide. For example, a larger gravel with a diameter of around ½ inch would typically cover 70 square feet at a 2-inch depth. Additionally, the coverage area may vary depending on the type and shape of the area to be covered, such as a curved space or an uneven surface.

How do I calculate how much pea gravel I need?
Calculating how much pea gravel you need for your project can be a challenging task. Before you begin, determine the length, width, and depth of the area you are working with. Multiply these measurements together to determine the volume of the area.
Once you have this number, it is time to determine how much pea gravel is needed. Depending on the desired coverage, you may need to purchase extra material to account for compaction and other factors.
For standard-sized pea gravel, like that often used in landscaping, the coverage is approximately 0. 25 cubic yards to cover 100 square feet and 2” in depth. To calculate the amount of pea gravel needed, multiply the length by the width by the depth and divide the total by the coverage (0.
25 cubic yards) to determine the total number of cubic yards.
For example, if you have a space that is 5 feet long by 10 feet wide by 2 inches deep, the total volume would be 1 cubic yard. Divided by the coverage (0. 25 cubic yards) the total number of cubic yards needed would be 4.
However, in order to accommodate for compaction and to ensure there is enough material, you may want to round up and purchase 5 cubic yards of pea gravel instead.
How much pea gravel for 300 square feet?
In order to figure out how much pea gravel you need for 300 square feet, you would need to consider a few variables. The depth of the gravel is the first variable to consider. Depending on the purpose of the installation and the type of area being covered, the required depth could range from 2 inches to 6 inches.
Let’s assume you will be using 3 inches of pea gravel for this installation. With that, you will need about 27 cubic yards of pea gravel. A cubic yard of pea gravel typically covers an area of approximately 100 square feet when spread 3 inches deep, so 27 cubic yards should cover an area of 300 square feet nicely.
To ensure an accurate measurement, it is best to take into account the shape of your area. If it is a square or rectangular area, then calculate the area by multiplying length x width, and then multiply the result by the desired depth.
For example, a 30 foot x 10 foot area at 3 inches deep would require 9 cubic yards of pea gravel. If the area is irregularly shaped, you may find it easier to divide the area into regular shapes and then add the volume of each shape together to get the total pea gravel needed.
You can either order the exact amount of pea gravel required, or you can include a bit of extra for any areas that may need additional gravel and for any spills during the installation process. A good rule of thumb is to order 10-15% more than you expect to need.
Should I put sand under pea gravel?
Yes, it is recommended to put a layer of sand under pea gravel to ensure good drainage and a level base for the gravel. Sand serves as a base for the pea gravel and helps to lock the rocks in place, preventing them from shifting and becoming uneven over time.
It also helps to prevent weeds from growing and the gravel from sinking in the soil below. When installing a layer of sand, it should be level, evenly spread across the area, and at least a few inches deep to ensure proper drainage and provide a stable base for the pea gravel.
Using a tamper to flatten the sand will help to ensure a tight, level base for your gravel. It’s important to note that sand does not provide any additional drainage, so it’s important to take this into consideration when installing your gravel.
For example, if you’re installing your gravel in an area with a soil drainage issue, adding a layer of sand may not be enough to prevent it from becoming soggy or water logged.
How thick should pea gravel be?
The ideal thickness for pea gravel will depend on the intended use. Generally, a depth of 2 to 4 inches is recommended for most ground cover applications, such as pathways, decorative features and patios.
Landscaping features such as driveways or beds for flower or plants require a depth greater than 4 inches. When laying down pea gravel for a driveway, a depth of 6 to 8 inches is usually recommended.
Laying it any shallower than 4 inches will likely lead to washouts and difficulty walking. When setting rock or flagstone paths or patios, a depth of 2-3 inches is usually best, with the pea gravel acting as a form of cushion beneath the material.
How many cubic feet are in a 50-pound bag of pea gravel?
A 50-pound bag of pea gravel typically contains approximately 0. 5 cubic feet of material. Pea gravel is usually sold in 50-pound bags, which measure approximately 1′ x 1′ x 1′ in size and contains approximately 0.
5 cubic feet. A cubic foot of pea gravel typically weighs around 100 pounds, so a 50-pound bag contains about half of a cubic foot. To figure out the exact number of cubic feet in a 50-pound bag, you need to know the exact density of the pea gravel.
How do you calculate pea gravel for a patio?
Calculating the amount of pea gravel you need for a patio can seem daunting, but is fairly simple when broken down into steps. To start, you’ll need to figure out the size of the area you’re looking to cover with pea gravel.
Then, you can use the following formula to calculate the amount of pea gravel you’ll need:
Length x Width x Depth of pea gravel = Volume in cubic feet
Once you have the volume, you can simply convert this figure into how many bags of pea gravel will be needed for the patio. As a general rule of thumb, 1 cubic foot of pea gravel is equivalent to about 0.
5 cubic feet of gravel — so if your volume calculation is 15 cubic feet, you’d need 30 bags of pea gravel.
Once you have the number of bags, you can determine how many tons of pea gravel is needed for the patio by using the following equation:
Number of bags x bag size / 2000 = Number of tons needed
For example, if 30 bags of pea gravel are needed, and each bag is 50 pounds, then your equation would look like this:
30 bags x 50 lbs / 2000 = 0.75 tons of pea gravel
Once you have this figure, you can adjust the amounts up or down depending on your individual project and/or local availability of pea gravel. You can also see if your local hardware store or garden center can provide you with adjusted amounts of pea gravel based on your figures to avoid over or under purchasing.
What area does a 1 ton bag of gravel cover?
A one-ton bag of gravel typically covers an area of around 15 square feet at a depth of 3 inches, however the exact coverage area will depend on the types of pebbles in the gravel and the size of the pebbles.
Generally, one ton of 57-grade gravel can cover approximately 80 to 100 square feet at a depth of 2 inches, whereas one ton of 28-grade gravel can cover approximately 120 to 150 square feet at a depth of 2 inches.
These measurements are only rough estimates and should never be used for exact measurements. To figure out the exact coverage area for a one-ton bag of gravel, it is best to measure the bag itself and use a calculator to find the exact area of the coverage.
How many bags pea gravel do I need for a 12×12 patio?
To answer this question, you will need to know the size of the stones you plan to use and the depth at which you plan to lay the gravel. Assuming you plan to lay the pea gravel at a recommended 2-3 inches of depth, to cover a 12×12 patio, you will need between 5 and 8 cubic yards of pea gravel, or between 200 and 300 50-pound bags of pea gravel.
To calculate the exact amount needed, measure the patio dimensions, determine the total area, translate that area into cubic yards and finally, multiply the cubic yards by the depth desired in inches.
For example, if the total area of the 12×12 patio is 12×12=144 square feet and the depth desired is 3 inches, 144 square feet x 0. 11111 = 16 cubic feet = 1. 11 cubic yards of pea gravel needed. To cover the patio, you will need to purchase 1.
11 x 200 = 222 bags of pea gravel.
Is 2 inches of pea gravel enough?
It depends on the purpose for which you are using the pea gravel. Generally, when using pea gravel to create a flat surface, such as a driveway, patio, or walkway, 2 inches is usually adequate. Anything less than 1.
5 inches is generally not recommended, since this can create an uneven surface and leave the space with a mottled look. However, if you are using pea gravel for a decorative purpose, such as a garden path, 2 inches may be enough, depending on the appearance you are looking for.
The amount of pea gravel you need for decorative purposes is largely a matter of personal preference. The general rule of thumb is to use at least 2 inches, as this can ensure that the gravel stays in place.
If you are installing a larger area with pea gravel, such as a patio or a driveway, you should use at least 3-4 inches of pea gravel. This helps to create a more level surface that is less prone to heaves and depressions.
How deep does pea gravel need to be to prevent weeds?
Pea gravel is a great option for preventing weeds, however the depth at which it should be applied depends on the situation. Generally speaking, it should be applied at least 3″ deep to ensure good coverage and impede the growth of weeds.
To further discourage weeds and minimize the amount of maintenance required, you should use a plastic edging between the pea gravel and the soil to form a barrier. This will ensure that the pea gravel doesn’t mix with the topsoil and make weeds easier to grow.
Once installed, you should also top off the pea gravel with an additional layer of 1″ of pea gravel to maintain the depth and provide a clean, neat appearance.
Can you put pea gravel directly on dirt?
Yes, you can put pea gravel directly on dirt or soil. However, if you are considering it for a long term solution, you should ensure that you prepare the soil or dirt first for increased stability of the pea gravel.
To do this, you should ensure that the soil is flat and even using a pitchfork or rake to remove any rocks, sticks, and other large debris. To further increase its stability, you should consider installing a tarp or a weed barrier layer that covers the entire area in order to keep the weed growth away.
After that, you can lay down a layer of coarse sand to create a more even surface before pouring the pea gravel. Make sure to add a good amount of gravel to the surface, around 3-4 inches thick and make sure to spread it evenly.
Once it is in place, rake it to level it off and make sure to check for firmness by testing it with the foot. Finally, you should leave it in place for about a week to let it settle so that the pea gravel can form a solid base.
