Understanding the Difference Between Carpet Area, Built-up Area, and Super Built-up Area

When purchasing a property, having clarity on carpet area, built-up area, and super built-up area can help in making well-informed decisions. These measurements influence the usable space, pricing, and overall property evaluation. This guide provides insights into these terms, their significance, and how they are calculated. 

What is Carpet Area?

Carpet area refers to the actual usable floor space within a property that can be covered by a carpet. It does not include the thickness of internal walls, balconies, terraces, or common areas. 

What is included in Carpet Area?

• Living room, bedrooms, kitchen, and bathrooms 
• Any internal passages or corridors inside the property 

What is excluded from Carpet Area?

• External and internal walls 
• Balcony, terrace, and verandah 
• Common spaces like staircases, lift shafts, and corridors 

Carpet Area is the key measurement for buyers as it determines the actual usable space within a property. 

What is Built-up Area?

Built-up area includes the carpet area plus the thickness of walls and other additional spaces, such as balconies or terraces. It gives a slightly larger figure than the carpet area. 

What is included in Built-up Area?

• Carpet Area 
• Internal and external walls 
• Balconies, terraces, and utility areas 

The built-up area is generally around 10-20% more than the Carpet Area. 

What is Super Built-up Area? 

Super built-up area is the total area, including the built-up area plus a proportionate share of common areas, such as corridors, staircases, lifts, and amenities. Developers often use this measurement while quoting prices. 

What is included in Super Built-up Area?

• Built-up area 
• Proportionate share of common areas (lobbies, staircases, lifts, clubhouses, etc.) 

The super built-up area is the highest among all three, often 25-40% more than the carpet area. 

Importance of Carpet Area, Built-up Area, and Super Built-up Area

Understanding these measurements is essential for home buyers because: 

• Carpet area determines the usable space within a home 
• Built-up area helps understand the actual constructed area 
• Super built-up area is often used for pricing in apartment projects 
• Ensures transparency while comparing properties and making investment decisions 

How to Calculate Carpet Area, Built-up Area, and Super Built-up Area

Each area is calculated using different formulas: 

• Carpet Area Calculation 
• Built-up Area Calculation 
• Super Built-up Area Calculation 

Example: If a property has a carpet area of 800 sq. ft., a built-up area of 1,000 sq. ft., and the common areas make up 400 sq. ft., then the Super Built-up Area would be 1,200 sq. ft. 

Difference Between Carpet Area, Built-up Area, and Super Built-up Area
 

Feature	Carpet Area	Built-up Area	Super Built-up Area
Includes Walls?	No	Yes	Yes
Includes Balconies?	No	Yes	Yes
Includes Common Areas?	No	No	Yes
Size Compared to Carpet Area	Same	10-20% more	25-40% more

Buyers should focus primarily on the carpet area, as it represents the actual usable space. Always verify these measurements with the builder or developer to ensure transparency in the property transaction.
