The online gravel calculator helps you to calculate the volume (cubic yards, cubic ft) and weight (tons, lbs) of gravel required to complete your project. Also, this online gravel cost calculator determines the total cost of the gravel which needs to complete the task. Our online aggregate calculator helps you to answers the questions like:

  •  how much gravel do i need to complete the project
  •  how much does a yard of gravel weigh
  •  how much stone do i need to complete driveway
  •  how much rock do i need
  •  how many yards in a ton of gravel

Keep reading to know how this gravel estimator works, formulas, types, and many other important & useful terms. Also, you can try our online roof pitch calculator that will assist you to measure the pitch and length of the rafters you are going to need for construction.

First of all, ahead to some basics!

What Are The Types of Gravel?

According to their different size & shape, they can be classified into following:

Bank Gravel:

Naturally a mixture of gravel with sand or clay present in the rivers or streams. It is also called “bank run” or “river run”.

Bench Gravel:

This type is located on the valley above the stream, indicating the previous position of stream when it was at higher level.

River Rock (Creek Rock):

River rock is generally round shaped and polished stones that are often covered with the stream or river bed. It is used as concrete aggregate and in paving the surfaces.

Crushed Stone:

Crushed stones type is the mixture of crushed rock pieces and stone. Crushed rock also known as “crusher run” “shoulder stone” “DGA (dense grade aggregate)” “QP (Quarry Process)” usually in the size of ¾ inch or less. Its common use is in surfacing of roads and driveways. This type may be made from granite, limestone and from other rocks.

Fine Gravel:

The type of gravel with the diameter of 2-8mm, termed as fine gravel.

Stone Dust:

The fine & crushed stones from the final stage of screen separation, such that stone is not separated from dust.

Lag Gravel:

This type left behind after the removal of the fine particles from the gravel.

Pay Dirt:

It is also known as pay gravel, is the high concentration of gold and other precious metals with gravel.

Pea Gravel:

It consists of rounded, small stones commonly used in concrete surfaces. If you are going to gravelling your path with pea gravel elements, then this pea gravel calculator helps you to determine the required quantity and volume of pea gravel for your work.

Piedmont Gravel:

This type consists of the coarse gravel carried from the high places by mountain streams and deposit on flat surfaces, where water runs slowly.

Plateau Gravel:

This type is usually found on the plateau or other regions.

For convenience, try this online aggregate calculator that lets you calculate the total weight, volume and cost of gravel required for specific gravel types.

How to Use the Gravel Calculator:

An aggregate calculator is 100% free and helps you to determine the speedy results accurately. Simply, follow the points for the exact calculations.

For Rectangular Surface:

Our gravel calculators give you a platform where you can determine the gravel calculations with following different material using:

  •  Length, width & depth.
  •  Area & depth.
  •  Volume.

Inputs:

  •  First of all, select the material to calculate all the calculations from the dropdown of this online tool.
  •  Then, enter the data in the designated fields according to the selected option.
  •  Once you are done, it’s time to hit calculate the button.

For Circular Surface:

Inputs:

  •  First of all, enter the diameter of the circular surface.
  •  Very next, plug-in the depth.
  •  After this, enter the density.
  •  Lastly, click the calculate button.

Outputs:

The online tool shows:

  •  The gravel volume needed.
  •  The gravel weight needed.
  •  Total cost of gravel.

Note:
No matter, it’s a rectangular surface or circular surface; there is an optional field of price per unit mass. If you enter the cost per unit mass then, this gravel cost calculator determines the total cost needed to fulfill the project.

How to Calculate How Much Gravel You Need (Step-by-Step)?

This online calculator estimates the volume & weight of gravel needed. So, we have manual calculations for both. Let’s begin!

For Volume Calculation:

To calculate the volume needed, follow the given steps:

  •  Measure the length & width of the area for which you going for the construction.
  •  Find out the area of the surface from length & width. \((A = L \times W)\).
  •  Determine the depth of the surface.
  •  Find out the volume by multiplying the area and depth.
  •  The volume obtained is the volume needed for the gravel to complete the project.

Let’s have an example:

Example:

A surface has \(18 ft\) long and \(21 ft\) wide with a depth of \(10 ft\). Then how much gravel do I need?

Solution:

\(L = 18 ft\)
\(W = 21 ft\)
\(D = 10 ft\)
So, find the area by,
\(A = L \times W\)
\(A = 18 \times 21\)
\(A = 378 ft^2\)
Now,

Calculate the volume by using the formula:

\(V = A \times D\)
\(V = 378 \times 10\)
\(V = 3780 ft^3\)

For Weight Calculation:

To calculate the weight needed, using the formula:

\(Density = \frac {mass}{volume}
\(mass = Density \times volume\)
You don’t have to remember the density; our gravel calculator sets this value by default.

Let’s try an example:

Example:

If the volume needed is \(3780 ft^3\) and the density is \(104.88 lb/ft^3\), then find the weight needed?

Solution:

Here,

\(Density = 104.88 lb/ft^3\)
\(Volume = 3780 ft^3\)
So,

\(mass = Density \times volume\)
\(mass = 104.88 \times 3780\)
\(mass = 396446.4 lbs (198.223 tons)\)

Frequently Ask Questions (FAQ’s For Gravel):

How to do gravel calculations with irregular shape?

If you have an irregular shapes area for which you have to do calculations, it’s a bit more difficult but generally you have to divide it in the regular shaped sections. Then, do gravel estimations on regular shaped areas and sum them together.

How much will a ton of gravel cover?

A ton of gravel will cover according to the following measurements:

\(¼\) to \(½\) inch gravel = \(100\) square feet.

\(½\) to \(1\) inch gravel = \(90\) square feet.

\(½\) to \(2\) inches gravel = \(80\) square feet.

How deep should I lay gravel?

You should usually lay 10mm aggregate at the depth of 30-40mm, but it is increased to 50mm on the driveway. A larger aggregate will better bond together than the smaller.

What is gravel used for?

It mixed with asphalt for road construction as well as mixing with and for the manufacturing of concrete. Its common use is to surface the roadways specially the icy roads.

Does crushed gravel drain well?

Yes, the crushed gravel drains well and is great in paving the blocks and in concrete for footpaths. So, if you have an area where water doesn’t drain, then add some crushed stone which is helpful for draining and for decorating feature.

Wrapping-it Up:

If you are looking to upgrade your driveway, lay a landscape path or simply looking to improve the yard with gravel, then you should know about the right amount of it you need. So, simply account to this online gravel calculator that determines the amount of material required to complete your project. People and builders use this online gravel cash calculator to get an estimate about the cost of gravel required for their different earthworks.
