Carpet Size And Cost Formula:

A carpet can be in a rectangle shape, circle, ellipse, pentagon, etc. So below we have mentioned the formulas for approximately all the shapes. Let’s take a look:  


Carpet area = carpet’s width × carpet’s length

Carpet cost = carpet area × carpet price per unit


Carpet area = π × radius²

Carpet cost = carpet area × carpet price per unit


Carpet area = axis A × axis B × π

Carpet cost = carpet area × carpet price per unit


\[ \text{Carpet area} = \frac{{\text{side}^2 \cdot \sqrt{25 + 10\sqrt{5}}}}{4} \]

Carpet cost = carpet area × carpet price per unit


\[ \text{Carpet area} = \frac{3}{2} \cdot \sqrt{3} \cdot \text{side}^2 \]

Carpet cost = carpet area × carpet price per unit

Other Shapes:

Carpet cost = carpet area × carpet price per unit

How To Calculate Carpet Size And Cost?

Go through the below-mentioned steps to calculate the carpet size and cost:

  • First of all, determine the dimensions of the area such as length and width 
  • Know the shape of the carpet that you need
  • Put the dimensions of the area in the above-listed formulas according to the shape you need and calculate carpet price, by multiplying size with the carpet cost per square foot. 

If it looks daunting, then look no further than the online carpet yardage calculator. This tool will allow you to calculate the carpet size precisely by just entering a couple of inputs. 


Suppose that the length of the rectangular room is 20ft and the width is 25 ft. The unit cost of carpet per square foot is 5. Then find the carpet price per square foot of the rectangular room.


Given that:

Room Length = 20 ft

Room Width = 25 ft

Carpet price per square foot = 5

Carpet area = carpet’s width × carpet’s length

Carpet area = 25 x 20 = 500 sqr ft

Carpet cost = carpet area × carpet price per unit

Carpet cost = 500 x 5 = 2500

This is the carpet cost per square foot and does not include the cost to install carpet. Different service providers cost different prices, so get the quote, and avail the services as per your budget.
