How easy was it to use our calculator? Did you face any problem, tell us!

The stone calculator finds the volume of stone and the cost to complete the project successfully. You can calculate the magnitude of the stone and its dimensions in imperial units (Inches, feet, or yards) and metric units like (centimeters or meters) by using this online tool. 

How Much Stone Quantity?

Estimating the cost and the quantity of the stone is a necessary task! The stone can be a rectangle or circular in shape. How much stone do I need for my current project is essential to answer?

For rectangular and circular shape stones the formulas are given as:

Volume = Length* Width* Depth

\(Volume = \pi\ \times \biggl({Diameter \over 2}\biggr)^2 \times Depth\)

You can calculate the stone needed for your project or landscape by the landscape stone calculator.


\(Density\,lb/ft^3 = {Mass\,(lb) \over Volume\,(ft^2)}\)

How to Find the Cost of the Stone?

If you have the price of the stone per unit mass or per unit volume, then you can work out the price or cost of the stone. With the crushed stone calculator, you can calculate the total cost of the stone required to make the project feasible.

\(Cost = Weight \times Price\,per\,unit\,mass\)

\(Cost = Volume \times Price\,per\,unit\,volume\)

Rectangular Stone Calculation:

Let’s consider that I am using crushed gravel and stones measuring 4 ft long, 2ft wide, and 0.75 ft deep. Consider the price of the stone is $ 50 per ton. Then calculate the stone needed for the area:


Length  = 14 ft

Width = 2ft

depth of the stone = 0.75 ft

Price = $ 50 per ton.


\(Volume = Length \times Width \times Depth = 4 \times 2 \times 9 = 0.222\,yd^3\)

The volume of the stone is 0.222 yd^3 and the stone volume calculator is a simple way to estimate the volume of stone.

\(Weight = Density \times Volume = 105\,lb/ft^3 \times 0.222\,yd^3 = 0.315\,t\)

The weight of the stone required is 0.315 tonnes, and to specify the quantity in the form of the tonnes is easy by the stone dust calculator, stone assists to specify the number of stones in the form of tones.

\(Cost = Weight \times Price\,per\,unit\,mass = 0.315\,t \times 50\,$/t = $15.75\)

The material calculator stone specifies the price for the rectangular stone and in this case, it is $15.75 or $ 16 in rounded form. 

Circular Stone Calculation:

Let’s have a stone of the density 100 lb/ft³ and its cost is $10 per yd³. The depth of the stone is 12 inches.


Density = 100 lb/ft³

Cost = $10 per yd³

depth of the stone = 12 inches


\(Volume = \pi\ \times \biggl({Diameter \over 2}\biggr)^2 \times Depth = \pi\ \times \biggl({10 ft \over 2}\biggr)^2 \times 12\,in = 2.909 ft^3\)

The volume of the stone is 2.909 ft^3 and the stone volume calculator is used to identify the volume of the circular stone.

\(Cost = Volume \times Price\,per\,unit\,volume = 2.909 ft^3 \times 10\,$/t = $29.09\)

Working of Stone Calculator:


  • Select the type of area or volume 
  • Enter the values in their respective field
  • Enter price per unit (optional)
  • Hit the calculate button


  • Stone volume and quantity in tons and cubic yards


How Do You Calculate Stone?

Multiply the length (L), in feet, by the width (W), in feet, by the height (H), in feet, and divide by 27. The stone yard calculator calculates the volume of the stone required per square area.

What Area Will 1 Ton of Stone Cover?

1 ton of stone will cover around  240 square feet with a 1” depth or 120 square feet with a 2” depth or 80 square feet with a 3” depth. The stone coverage calculator makes it possible to identify the depth and area of stone.
