Gaj to Square Feet — Conversion Formula, Table & Calculator
Introduction
If you’re scanning a real estate listing for a property in Delhi, Gurgaon, Lucknow, or Chandigarh, it’s highly probable the plot size has been described in Gaj. However, in your loan sanction letter, architect’s drawings, or RERA registration documents, the area will be specified in square feet.
This difference in units often causes confusion and in some instances, leads to errors during property transactions.
This guide equips you with the correct conversion factor, formula, a readily available table, and practical examples for the real estate industry so that you know precisely what you’re purchasing.
How Many Square Feet is 1 Gaj?
1 Gaj = 9 Square Feet
This is a generally accepted standard throughout India, land records and property deeds/documents in all Indian states. Period.
Think of it this way: 1 Gaj is a square that measures 3 feet on each side — which gives you 3 × 3 = 9 square feet.
| Unit | Value |
|---|---|
| 1 Gaj | 9 Square Feet |
| 1 Gaj | 1 Square Yard |
| 1 Gaj | 0.836 Square Meters |
| 1 Gaj | 0.000205 Acres |

What Is a Gaj?
Gaj (also written as Gaz or Guz in some regions) is a unit of area measurement that has been in use for hundreds of years. This unit was used to measure land and fabric during the Mughal era.
In India today, Gaj is most frequently used to measure land while buying and selling of property in:
- Delhi NCR: DDA plots, builder floors, and plotted colonies
- Punjab: Residential layouts, plots of plotted colonies (Amritsar, Ludhiana, and Mohali)
- Haryana: DDJAY schemes, plots of licensed colonies in Gurgaon and Faridabad
- UP: LDA plots (Lucknow) residential plots in (Agra and Meerut)
- Rajasthan: Some older city regions (Jaipur and Jodhpur)
- Himachal Pradesh: Land records (smaller towns)
In South India (Karnataka, Tamil Nadu, Kerala, Maharashtra), square feet or square meters are most used, and there is hardly any usage of Gaj.
Gaj to Square Feet Formula
Square Feet = Gaj × 9
And if you need to go the other way:
Gaj = Square Feet ÷ 9
Worked Examples
Example 1 — Convert 50 Gaj to Square Feet 50 × 9 = 450 sq ft
Example 2 — Convert 100 Gaj to Square Feet 100 × 9 = 900 sq ft
Example 3 — Convert 200 Gaj to Square Feet 200 × 9 = 1,800 sq ft
Example 4 — Convert 1,800 sq ft back to Gaj 1,800 ÷ 9 = 200 Gaj

What Is a Square Foot?
One square foot is among the most prevalent units of area across real estate globally. One square foot is basically a square with each side precisely measuring one foot (12 inches).
In India, square feet is used in:
Every sale deed and agreement document related to any property
Registration documents for any RERA project
Architect drawings and plans related to construction
Loan sanction letters in case of home loans
The other prominent European nations have accepted square meters; however, countries like India (in contrast to the USA, UK, and many Southeast Asian nations) still use square feet as an acceptable form for general real estate transactions.
How to Convert Without a Calculator (Quick Mental Math Trick)
Since 9 is 10 minus 1, you can do this in your head:
Step 1: Multiply the Gaj by 10 Step 2: Subtract the original Gaj value
Example: 45 Gaj to sq ft
- 45 × 10 = 450
- 450 – 45 = 405 sq ft ✅
This works for any Gaj value and takes less than 10 seconds.
Real Estate Scenarios: Putting It Into Practice
Scenario 1 — Evaluating a Plot Deal
A dealer in Mohali offers you a 120 Gaj plot at ₹18,000 per Gaj.
- Area = 120 × 9 = 1,080 sq ft
- Total cost = 120 × ₹18,000 = ₹21,60,000
- Price per sq ft = ₹21,60,000 ÷ 1,080 = ₹2,000/sq ft
That last number — price per sq ft — lets you benchmark it against other properties in the same area instantly.
Scenario 2 — Comparing Two Properties
- Property A: 80 Gaj in Noida = 720 sq ft
- Property B: 750 sq ft in Faridabad = 83.3 Gaj
Property B gives you about 4% more area for the same listed Gaj count. Always compare in the same unit.
Scenario 3 — Understanding FAR (Floor Area Ratio)
You have a 100 Gaj (900 sq ft) plot. Your local authority allows a FAR of 2.0.
- Total buildable area = 900 × 2 = 1,800 sq ft
- You can build 1,800 sq ft spread across multiple floors
