Carpet Area vs Super Built-Up Area: Essential Guide for Homebuyers
Understand the key differences between carpet area, built-up area, and super built-up area. Make informed property decisions with Dura Housing.

When purchasing a property, understanding the distinctions between carpet area, built-up area, and super built-up area is crucial. These terms significantly impact the property’s pricing and the actual usable space you receive. This guide aims to demystify these concepts, helping you make informed decisions in your home-buying journey.
📐 What is Carpet Area?
The carpet area refers to the actual usable floor area within the walls of an apartment. It includes spaces like bedrooms, living rooms, kitchens, and bathrooms but excludes the thickness of inner walls, balconies, terraces, and common areas.

Key Features:
Usable Space: Includes all rooms within the apartment.
Exclusions: Does not account for balconies, terraces, or common areas.
RERA Definition: As per the Real Estate Regulatory Authority (RERA), carpet area is the net usable floor area of an apartment, excluding external walls, service shafts, balconies, and verandas.
🏢 What is Built-Up Area?
The built-up area encompasses the carpet area plus the thickness of walls and other unusable areas within the apartment, such as balconies and terraces.

Calculation:
Built-Up Area = Carpet Area + Wall Thickness + Balcony Area
Key Features:
Includes: Internal and external wall thickness, balconies, and terraces.
Typically: 10-20% more than the carpet area.
🏘️ What is Super Built-Up Area?
The super built-up area, often termed as the “saleable area,” includes the built-up area plus a proportionate share of common areas like lobbies, staircases, elevators, and amenities.

Calculation:
Super Built-Up Area = Built-Up Area + Proportionate Share of Common Areas
Key Features:
Includes: Common amenities such as clubhouses, gardens, and corridors.
Loading Factor: Developers apply a loading factor to the carpet area to arrive at the super built-up area. This factor typically ranges between 25% to 60%.
📊 Comparative Table
Feature | Carpet Area | Built-Up Area | Super Built-Up Area |
Definition | Usable floor area | Carpet area + walls | Built-up area + common areas |
Includes | Rooms | Rooms + walls + balcony | Built-up area + amenities |
Excludes | Walls, balconies | Common areas | - |
Percentage | Base | +10-20% | +25-60% (loading factor) |
🧮 Understanding the Loading Factor
The loading factor is the difference between the super built-up area and the carpet area. It accounts for the proportionate share of common areas allocated to an individual unit.
Example:
Carpet Area: 1,000 sq.ft.
Loading Factor: 30%
Super Built-Up Area: 1,000 + (30% of 1,000) = 1,300 sq.ft.
Understanding the loading factor helps in assessing the actual usable space and the cost implications.
🏗️ Why These Distinctions Matter
Pricing Transparency: Properties are often priced based on the super built-up area, which can be misleading if buyers are unaware of the actual usable space.
Loan Approvals: Financial institutions consider the carpet area when approving home loans, affecting loan eligibility and amount.
Resale Value: Understanding these areas ensures better negotiation and resale value assessment.
🏡 Tips for Homebuyers
Request Detailed Breakdowns: Always ask for a detailed area statement from the builder, specifying carpet, built-up, and super built-up areas.
Compare Properties: Use carpet area as a standard metric to compare different properties.
Understand the Loading Factor: A higher loading factor means less usable space. Aim for properties with a lower loading factor.
Consult Professionals: Engage with real estate experts or legal advisors to understand the implications fully.
