About Carpet Area Calculator

Understanding Real Estate Area Measurements

When buying or renting property, it's crucial to understand the different types of area measurements. This calculator helps you compute carpet area, built-up area, and super built-up area for residential properties.

Features

  • Add multiple rooms with custom dimensions
  • Calculate carpet area (usable floor space)
  • Calculate built-up area (includes walls)
  • Calculate super built-up area (includes common areas)
  • Adjustable wall thickness
  • Include balcony area
  • Customizable common area loading
  • Visual comparison charts
  • Conversion to square meters
  • Room-by-room breakdown

Area Definitions

Carpet Area:
The actual usable floor area where you can lay a carpet. It excludes the thickness of inner walls but includes the space occupied by internal fixtures.
Built-up Area:
Carpet area plus the area covered by walls, balconies, and other enclosed spaces. Typically 10-15% more than carpet area.
Super Built-up Area:
Built-up area plus proportionate share of common areas like lobby, stairs, elevators, and amenities. Also called "Saleable Area."

How to Use

  1. Add all rooms in your property
  2. Enter length and width for each room
  3. Set wall thickness (typically 0.5 feet)
  4. Enter balcony area if applicable
  5. Set common area loading percentage
  6. View calculated areas instantly

Common Area Loading

Common area loading is the percentage added to built-up area for shared spaces. Typical ranges:

  • Low-rise buildings: 10-15%
  • Mid-rise buildings: 15-20%
  • High-rise buildings: 20-25%
  • Luxury apartments: 25-30%

Important Notes

  • RERA (Real Estate Regulatory Authority) mandates that property prices should be quoted based on carpet area
  • Always verify which area measurement is being used in property documents
  • Higher common area loading means you're paying for more shared spaces
  • Wall thickness can vary; typical range is 0.4-0.6 feet

Use Cases

  • Evaluating property before purchase
  • Comparing different properties
  • Understanding pricing structure
  • Planning interior design
  • Calculating property tax
