What Is Carpet Area, Built-Up Area, and Super Area? Explained with Gurgaon Real Estate Examples
Buying a home in Gurgaon? Then you must have come across confusing terms like:
- Carpet Area
- Built-Up Area
- Super Built-Up Area
Don’t worry — you’re not alone! These terms are often misunderstood, but they are very important when you’re comparing property prices and sizes.
In this blog post, we’ll explain what each one means, how they affect your home purchase, and give you real examples from Gurgaon projects in 2025.
✅ What Is Carpet Area?
Carpet Area is the actual usable area inside your home — the space where you can lay a carpet and walk around.
Carpet Area includes:
- Bedrooms
- Living room
- Kitchen
- Bathrooms
- Internal walls
It does NOT include:
- Balconies
- Terraces
- External walls
- Common areas like lobby, lift, or staircase
📌 Important: As per RERA (Real Estate Regulatory Authority), builders must now clearly mention the carpet area in all sales agreements.
Example (Gurgaon):
A 2BHK apartment in Sector 92, Gurgaon by Signature Global may have:
- Carpet Area: 645 sq.ft
- Price: ₹55 lakhs
So, price per sq.ft = ₹8,527 (approx.)
🧱 What Is Built-Up Area?
Built-Up Area is the carpet area + the walls and balcony. It gives a slightly bigger number than carpet area.
Built-Up Area includes:
- Carpet area
- Internal and external walls
- Balcony
- Utility areas
Rule of Thumb:
Built-Up Area = Carpet Area + 10–20%
Example (Gurgaon):
Using the same apartment:
- Carpet Area: 645 sq.ft
- Built-Up Area: ~775 sq.ft
This is still the private space within your apartment.
🏢 What Is Super Built-Up Area?
Also known as “Saleable Area,” this is the built-up area plus your share of common spaces like:
- Staircase
- Lift lobby
- Clubhouse
- Parking
- Garden or hallways
This is the number usually shown in brochures — because it makes the apartment sound bigger!
Formula:
Super Built-Up Area = Built-Up Area + Proportionate Share of Common Areas
👉 Developers often add 25–35% extra on top of the carpet area as super area.
Example (Gurgaon - M3M Capital, Sector 113):
- Carpet Area: 1,050 sq.ft
- Built-Up Area: ~1,250 sq.ft
- Super Built-Up Area: ~1,450 sq.ft
- Price: ₹1.35 Cr
- So price per sq.ft (on super area) = ₹9,310
But if calculated based on carpet area:
- ₹1.35 Cr ÷ 1,050 = ₹12,857/sq.ft
This is why understanding area types is very important!
📏 Key Measurements to Pay Attention To
| Area Type | What’s Included |
|---|---|
| Carpet Area | Usable area inside walls (no balconies/walls) |
| Built-Up Area | Carpet area + walls and ducts |
| Super Built-Up Area | Built-up area + share of common amenities (lifts, stairs, lobby) |
Tip: Always calculate price per square foot based on carpet area to know true value.
📊 Comparison Table
| Area Type | What’s Included | Bigger or Smaller? |
|---|---|---|
| Carpet Area | Usable indoor space | ✅ Smallest |
| Built-Up Area | Carpet + walls/balcony | 🔄 Medium |
| Super Built-Up Area | Built-up + common areas | ❗ Largest (and most advertised) |
⚠️ Why Buyers in Gurgaon Should Care
- You pay based on super built-up area, but you live in the carpet area.
- Projects may look cheaper, but the usable space is small.
- Always compare carpet areas between two projects for the real value.
🔍 Tips Before You Buy
✅ Always ask the builder for the carpet area.
✅ Check if common area loading is more than 30%.
✅ Confirm RERA carpet area before booking.
✅ Compare effective price per sq.ft based on carpet area, not just super area.
✅ Visit a sample flat to judge actual space.
🏁 Conclusion
Understanding the difference between carpet area, built-up area, and super built-up area will help you make a smarter decision when buying a property in Gurgaon.
Don’t fall for just the big number — ask how much space you actually get to live in.
