When buying or selling a property, you will often hear terms like Gaj, Square Feet, Square Yard, Square Meter, Bigha, Acre, and Hectare. Understanding these measurements is important because property prices, plot sizes, and construction areas are often discussed using different units.
If you are planning to buy a flat, builder floor, plot, or independent house, knowing these terms can help you compare properties and understand the actual size of the property.
What Is Gaj?
Gaj is a commonly used unit of land measurement in India, especially in Delhi, Haryana, Uttar Pradesh, Rajasthan, and nearby regions.
In real estate, 1 Gaj is generally equal to 1 Square Yard.
1 Gaj = 1 Square Yard = 9 Square Feet
For example:
- 50 Gaj = 450 Sq. Ft.
- 100 Gaj = 900 Sq. Ft.
- 150 Gaj = 1,350 Sq. Ft.
- 200 Gaj = 1,800 Sq. Ft.
- 500 Gaj = 4,500 Sq. Ft.
So, if someone says they own a 100 Gaj plot, it means the plot has an area of approximately 900 square feet.
What Is Square Feet (Sq. Ft.)?
Square Feet, commonly written as Sq. Ft., is one of the most widely used property measurement units in India.
It is commonly used to describe the size of:
- Flats
- Apartments
- Builder floors
- Houses
- Commercial properties
- Office spaces
For example, if a flat is 1,200 Sq. Ft., its total measured area is 1,200 square feet.
Gaj to Square Feet
The basic conversion is: 1 Gaj = 9 Sq. Ft.
Therefore: 100 Gaj × 9 = 900 Sq. Ft.
What Is a Square Yard?
A Square Yard (Sq. Yd.) is another common unit used for measuring land.
In many parts of North India, people commonly use the word Gaj instead of Square Yard.
1 Square Yard = 1 Gaj = 9 Square Feet
So, a 100 Square Yard plot and a 100 Gaj plot represent the same area.
What Is Square Meter?
Square Meter (Sq. M.) is an international metric unit used for measuring area. It is also commonly used in property documents and official measurements.
1 Square Meter = Approximately 10.76 Sq. Ft.
For example: 100 Sq. M. ≈ 1,076 Sq. Ft.
If a property is listed in square meters, converting it into square feet can make it easier to compare with other properties.
What Is an Acre?
An Acre is a larger unit of land measurement and is generally used for large plots, agricultural land, development projects, and large real estate projects.
1 Acre = 43,560 Sq. Ft.
Since: 1 Gaj = 9 Sq. Ft.
Therefore: 1 Acre ≈ 4,840 Gaj
Acre is particularly useful when discussing large land parcels rather than individual flats or small residential plots.
What Is a Hectare?
A Hectare is another large land measurement unit commonly used for agricultural and large land parcels.
1 Hectare = 10,000 Sq. M.
It is approximately equal to: 107,639 Sq. Ft.
One hectare is approximately 2.47 acres.
Carpet Area, Built-Up Area and Super Built-Up Area
Apart from land measurement units, buyers of flats and apartments should understand three important terms: Carpet Area, Built-Up Area, and Super Built-Up Area.
Carpet Area refers to the actual usable floor area inside the apartment, broadly representing the space where you can use or place a carpet. It generally excludes areas such as external walls and certain common areas.
Built-Up Area generally includes the carpet area along with the thickness of internal and external walls and certain attached areas such as balconies, depending on how the property is defined.
Super Built-Up Area can include the built-up area plus a proportionate share of common areas such as:
- Lobbies
- Staircases
- Corridors
- Lifts
- Other common facilities
This is why two properties with the same quoted area may not provide exactly the same usable space.
Why Understanding Property Measurements Is Important
Before buying a property, understanding its measurement can help you:
Compare Properties Easily: A property may be advertised in Gaj, while another is listed in Square Feet. Converting both into the same unit makes comparison easier.
Understand the Actual Property Size: Knowing the difference between carpet area, built-up area, and super built-up area helps you understand how much usable space you are actually getting.
Calculate Property Price: If you know the property size and total price, you can calculate the approximate price per square foot or price per Gaj.
Avoid Confusion: Real estate terminology can sometimes be confusing, especially for first-time buyers. Understanding basic measurements makes the buying process more transparent.
Make Better Investment Decisions: Whether you are buying a plot, flat, builder floor, or independent house, knowing the exact measurement helps you evaluate the property more effectively.
Learn Real Estate Terms To Get Better Knowledge
Before finalizing any property deal, always check the official property documents, sanctioned plans, and applicable measurement definitions rather than relying only on the area mentioned in an advertisement.
Understanding these basic real estate terms can help you make a more informed decision when buying property.
