Carpet Area Calculator

When you’re buying, selling, or renting property, one of the most important terms you’ll come across is carpet area. Simply put, carpet area is the actual usable floor area within the walls of an apartment or house, excluding thickness of inner walls, balconies, and common spaces like lifts and lobbies.

The Carpet Area Calculator is a smart tool that helps you quickly and accurately measure the true usable area of your property. Instead of manually calculating dimensions, this tool simplifies the process by allowing you to input basic details like built-up area, wall thickness, and other parameters.

This makes it especially useful for:

• Homebuyers who want to know what they’re really paying for
• Builders and developers who must present transparent measurements
• Interior designers who need accurate usable space for planning

How to Use the Carpet Area Calculator (Step by Step)

1. Enter Built-Up Area
   Input the total built-up area of the property (includes walls, carpet area, and utility areas).
2. Provide Wall Thickness
   Specify the average thickness of the walls, since carpet area excludes wall measurements.
3. Subtract Balcony/Utility Space (if any)
   If the property includes balconies or verandas, subtract their area.
4. Click Calculate
   The tool applies the formula and instantly gives you the carpet area.

Example Calculation

👉 Suppose an apartment has:

• Built-up area: 1,200 sq. ft.
• Wall thickness contribution: 120 sq. ft.
• Balcony/utility space: 80 sq. ft.

Carpet Area = Built-up Area – Wall Area – Balcony/Utility Space
Carpet Area = 1200 – 120 – 80 = 1,000 sq. ft.

So, even though the property is advertised as 1,200 sq. ft., the actual usable carpet area is 1,000 sq. ft.
