Introduction
Understanding property area measurements is one of the most important aspects of buying real estate in India. Many buyers get confused between carpet area, built-up area, and super built-up area. Developers often advertise larger super built-up numbers, which may not reflect the actual usable space available inside the home.
This guide clearly explains the differences between these three terms and how they affect property pricing and decision-making.
1. What is Carpet Area?
Carpet area refers to the actual usable floor area inside the walls of a property. It includes bedrooms, living room, kitchen, bathrooms, and internal partitions but excludes external walls, balconies, and common areas.
Under RERA regulations, developers are required to sell properties based on carpet area, increasing transparency for buyers.
2. What is Built-Up Area?
Built-up area includes the carpet area plus the thickness of internal and external walls, balconies, and utility areas. It is generally 10–20% higher than carpet area.
This measurement gives a broader understanding of the total constructed space but still excludes common areas such as lifts and staircases.
3. What is Super Built-Up Area?
Super built-up area includes built-up area plus proportionate share of common areas such as lobby, lift, clubhouse, and corridors. This is often referred to as the saleable area.
Super built-up area can be 20–40% larger than carpet area depending on the project amenities.
4. Why This Difference Matters
Property prices are usually quoted based on super built-up area, which can mislead buyers about actual usable space. Understanding carpet area helps buyers compare projects accurately.
5. RERA Impact on Transparency
RERA mandates that developers disclose carpet area clearly in sales agreements. This regulation protects buyers from inflated area calculations.
6. How to Calculate Price Per Square Foot
Buyers should calculate price per square foot based on carpet area for accurate comparison. A property priced at ₹5,000 per sq ft super built-up may effectively cost much more when converted to carpet area basis.
7. Practical Example
If a 1,200 sq ft super built-up apartment has a 900 sq ft carpet area, the usable space is significantly smaller than advertised. This difference affects furniture planning and space utilization.
Conclusion
Understanding carpet area, built-up area, and super built-up area empowers buyers to make informed decisions. Always verify carpet area before purchasing and compare projects based on actual usable space rather than promotional numbers.
Clarity in area measurements prevents overpayment and ensures transparency in property transactions.
