Enter the length and width of the room into the calculator to determine the carpet cut size. This calculator can also evaluate any of the variables given the others are known.

Carpet Cut Formula

The following formula is used to calculate the carpet cut size.

CC = (L * W) 


  • CC is the carpet cut size (square feet) L is the length of the room (feet) W is the width of the room (feet)

To calculate the carpet cut size, multiply the length of the room by the width of the room. The result will give you the total square footage of carpet needed for the room.

What is a Carpet Cut?

A carpet cut refers to the process of cutting a piece of carpet to fit a specific size or shape, usually for installation in a room or space. This can involve measuring the area, marking the carpet, and using a sharp tool such as a utility knife to make the cut. The goal is to ensure the carpet fits perfectly within the designated area, without any excess or shortage.

How to Calculate Carpet Cut?

The following steps outline how to calculate the Carpet Cut size.

  1. First, determine the length of the room (L) in feet.
  2. Next, determine the width of the room (W) in feet.
  3. Next, gather the formula from above = CC = (L * W).
  4. Finally, calculate the Carpet Cut size.
  5. After inserting the values for L and W into the formula and calculating the result, check your answer.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Length of the room (L) = 10 feet

Width of the room (W) = 8 feet
