A gaj is a square yard, which is exactly 9 square feet, and unlike bigha it never changes by district or state. Convert below, then see what each common plot size actually fits once setbacks are taken out.
Short answer
One gaj equals exactly 9 square feet, because a gaj is a square yard and a yard is 3 feet. So 100 gaj is 900 sq ft, 200 gaj is 1,800 sq ft and 500 gaj is 4,500 sq ft. Unlike bigha, the gaj does not vary by state or district, which is why plot sizes across North India are quoted in it.

The short answer
1 gaj = 9 square feet. That is the whole conversion and it has no exceptions.
A gaj is the Hindi word for a yard. A square yard is a square three feet on each side, so three times three gives nine square feet. Multiply gaj by 9 for square feet, divide square feet by 9 for gaj.

Why gaj never varies
This matters more than it sounds. Bigha is a regional unit that changes between districts, which makes it the most argued-about number in a North Indian land deal. Gaj is a yard, the yard is a defined imperial unit, and nobody gets to have a local version of it.
That is exactly why plots in and around Jaipur are sold in gaj while the agricultural land they were carved from is recorded in bigha. The moment land becomes a plotted project, the selling unit switches to something unambiguous.

Standard plot sizes in gaj
Common Jaipur plot sizes at true relative scale. Dimensions are indicative; two plots of the same gaj can have very different shapes.
Plotted projects on the Jaipur corridors tend to repeat a small set of sizes, because those are the sizes that sell. Knowing what each one is in square feet makes a price per gaj comparable against a price per square foot.

Dimensions are indicative. Two plots of the same gaj can have very different shapes, and a narrow deep plot builds differently from a wide shallow one. Ask for the frontage and the depth, not just the area.
What a plot actually fits after setbacks
Buyers routinely assume the plot area is the house area. It is not. Building bye-laws require setbacks on the front, rear and sides, and the permitted ground coverage and floor area ratio cap how much you can actually build.
As a working rule, ground coverage on a residential plot is commonly permitted in the region of 60 to 75 percent depending on plot size and local rules, so a 200 gaj plot of 1,800 sq ft may give you somewhere around 1,100 to 1,350 sq ft of ground floor footprint before you count upper floors.
Confirm before you buy, not after: ground coverage, FAR and setback rules are set by the local authority and change with plot size, road width and zone. Ask the seller for the sanctioned layout and check the permitted coverage for that specific plot with the JDA or the relevant local body.
Gaj, square yard and square metre
Gaj and square yard are the same thing, so any listing that quotes both is quoting one number twice. Square metre is the unit that appears on official records and approvals, which is where confusion creeps in.
One gaj is 0.8361 square metres. One square metre is 1.196 gaj. If a sanctioned plan states 167 sq m and the broker says 200 gaj, those agree.

Gaj to bigha
When a plotted project is carved out of agricultural land, the two units meet. A pucca bigha is 3,025 gaj and a kaccha bigha is 1,936 gaj.
That means one pucca bigha yields roughly fifteen 200-gaj plots before you take out roads, parks and setbacks. After layout, the saleable share is usually well under that, which is the number that actually decides a plotted project economics.

Reading a plot listing honestly
Price per gaj against price per sq ft. Divide the per-gaj price by 9 to compare with anything quoted per square foot.
Area in the listing against area on the layout. The sanctioned layout is the one that counts.
Frontage and depth, not just area. A 200 gaj plot at 20 x 90 ft builds very differently from 30 x 60 ft.
Road width in front of the plot. It affects both permitted construction and resale value.
Whether the figure is plot area or built-up area. These get used interchangeably in conversation and they are not the same.
Approval status. A gaj of approved plot and a gaj of unapproved plot are not the same asset at any price.
FAQs
How many square feet is 1 gaj?
Exactly 9 square feet. A gaj is a square yard and a yard is 3 feet, so 3 times 3 gives 9. This conversion does not change by state or district.
How many square feet is 100 gaj?
900 square feet, which is about 83.6 square metres. A 100 gaj plot is commonly around 25 by 36 feet, though the exact dimensions vary.
How many square feet is 200 gaj?
1,800 square feet, or about 167.2 square metres. This is one of the most common house plot sizes sold in and around Jaipur.
Is gaj the same as square yard?
Yes, exactly the same. Gaj is the Hindi word for yard, so a gaj is a square yard. A listing that quotes both is repeating one number.
How many gaj are in one bigha?
A Rajasthan pucca bigha is 3,025 gaj and a kaccha bigha is 1,936 gaj. Unlike gaj, the bigha varies by district, so check your revenue record.
How do I convert gaj to square metres?
Multiply gaj by 0.8361. So 200 gaj is about 167.2 square metres. Going the other way, multiply square metres by 1.196 to get gaj.
Can I build on the full plot area?
No. Setbacks, permitted ground coverage and floor area ratio limit how much of a plot you can build on. Ground coverage on residential plots is commonly permitted in the region of 60 to 75 percent depending on plot size and local rules, so confirm the figure for your specific plot with the local authority before planning.
Why are Jaipur plots sold in gaj and not bigha?
Because gaj is unambiguous. Bigha changes value between districts and between pucca and kaccha, which makes it unusable for selling individual plots. Agricultural land is recorded in bigha; once it becomes a plotted project it is sold in gaj.
