Carpet Area vs Built-Up Area: What You Need to Know
Understanding real estate jargon is crucial when buying a property. One of the most misunderstood concepts in Indian real estate is the difference between carpet area, built-up area, and super built-up area. Let’s break them down clearly so you know exactly what you’re paying for.

What is Carpet Area?
- Definition: The actual usable area within the walls of your flat. Think of it as the area where you can lay a carpet.
- Includes: Bedroom, living room, kitchen, bathrooms, internal partition walls
- Excludes: Balcony, terrace, external walls, common areas
Tip: Carpet area is the most accurate reflection of usable space in a home.
What is Built-Up Area?
- Definition: Carpet area + thickness of internal/external walls + balcony
- Typically: 10–20% more than the carpet area
- Includes: Carpet area + wall thickness + balcony/veranda
Builders used to quote prices based on built-up area, but now RERA mandates carpet area disclosure.
What is Super Built-Up Area?
- Definition: Built-up area + proportionate share of common areas
- Includes: Lobbies, lifts, staircases, clubhouse, and other shared amenities
Also known as the “saleable area,” it’s used to calculate the price per sq. ft. before RERA regulation came into effect.
Why It Matters
- Price Clarity: Always compare carpet area across projects for a true value comparison
- Loan Approval: Banks consider carpet area when evaluating property for home loans
- Transparency: RERA has made it mandatory to sell homes based on carpet area only
Sample Comparison
Area Type | Square Feet |
Carpet Area | 600 sq. ft. |
Built-Up Area | 720 sq. ft. |
Super Built-Up Area | 900 sq. ft. |
A property priced at ₹20,000/sq.ft. may seem expensive, but it depends on what area that rate is being applied to.
