Gaj to Sq Ft Conversion Table: 100 to 500 Gaj Plot Dimensions

Short answer: 1 Gaj equals exactly 1 Square Yard, which converts to 9 Square Feet or 0.8361 Square Metres across Chandigarh, Mohali, Panchkula, and Zirakpur. In urban GMADA and private colony developments, standard plot benchmarks measure: 100 Gaj equals 900 square feet (4 Marlas, commonly 20x45 ft or 30x30 ft); 150 Gaj equals 1,350 square feet (6 Marlas, typically 25x54 ft); 200 Gaj equals 1,800 square feet (8 Marlas, standard 30x60 ft); 250 Gaj equals 2,250 square feet (10 Marlas / Half Kanal, standard 30x75 ft); and 500 Gaj equals 4,500 square feet (1 Kanal / 20 Marlas, standard 50x90 ft). In rural revenue records (Jamabandi fard), 1 traditional Marla equals 272.25 sq ft and 1 Kanal equals 605 Gaj (5,445 sq ft), making it essential to confirm whether a registry specifies urban square yards or agricultural revenue shares.

Why Plot Measurements in the Tricity Create Expensive Confusion

If you have spent any time looking for residential plots across Mohali, Kharar, Zirakpur, or Panchkula, you have heard property consultants switch between Gaj, square feet, square yards, Marlas, and Kanals within a single breath. A broker standing on a vacant parcel in Sunny Enclave Kharar will quote a price "per Gaj," hand you an allotment letter measured in "square yards," and describe the layout as a "4 Marla kothi site."

When buyers fail to grasp how these land units translate into physical feet, two expensive problems occur: they pay for phantom square footage on tapered plots, or they confuse urban municipal benchmarks with rural agricultural revenue shares. Local real estate Instagram pages and creators are an active source of listings and area info for Tricity renters and property buyers today, often advertising plots with catchphrases like "100 Gaj independent villa" or "200 Gaj luxury site" without explaining the actual front, depth, or statutory building setbacks.

Hoomzz lists physically verified rentals and verified property options across Chandigarh, Mohali, Panchkula and Zirakpur. To help plot buyers, builders, and independent home builders make informed decisions, this guide provides the exact mathematical conversions, standard front and depth dimensions, and legal registry distinctions used across the Tricity in 2026.

The Core Mathematical Relationship: Gaj, Square Yards, Feet & Metres

The term Gaj (derived from the historic linear unit guz) is universally treated in North Indian urban real estate as a square unit—specifically, one square yard. The mathematical conversion factors are fixed:

1 Linear Gaj (Yard): 3 Linear Feet = 36 Inches = 0.9144 Metres
1 Square Gaj: 1 Square Yard = 9 Square Feet = 0.836127 Square Metres
1 Square Metre: 1.19599 Square Yards (Gaj) = 10.7639 Square Feet
1 Square Foot: 0.1111 Square Yards (1/9 Gaj) = 0.0929 Square Metres

To convert any plot area from Gaj to square feet, multiply the Gaj count by 9. To convert square feet back to Gaj, divide by 9. For example, an 1,800 square foot plot divided by 9 equals exactly 200 Gaj. You can also calculate construction budgets and property metrics using Hoomzz real estate calculators.

400 Gaj	3,600 sq ft	334.45 sq m	16 Marlas	40 ft × 90 ft	Aerocity Block C & D, Eco City New Chandigarh
500 Gaj	4,500 sq ft	418.06 sq m	20 Marlas (1 Kanal)	50 ft × 90 ft 45 ft × 100 ft	Gold standard 1 Kanal in Chandigarh sectors, Mohali Sectors 68–71, Aerocity

The 4-Marla Misunderstanding: Never purchase a plot quoted purely in Marlas without verifying the exact square footage written in the conveyance deed. In GMADA sectors and approved private townships, 4 Marlas equals 100 Gaj (900 square feet). In rural agricultural revenue land (Jamabandi fard), 4 Marlas equals 121 Gaj (1,089 square feet). If a seller prices a 100 Gaj plot using the agricultural Marla rate, you overpay by 21% on basic unit economics.

The Critical Split: Urban GMADA Norms vs Rural Punjab Revenue Records

One of the most frequent sources of property disputes in Punjab and Haryana is the difference between the urban planning standard and the revenue record standard.

When the Greater Mohali Area Development Authority (GMADA) and the Punjab Urban Planning and Development Authority (PUDA) plan urban sectors like Aerocity, IT City, or New Chandigarh, they use a simplified decimal-compatible conversion where 1 Marla is standardized to 25 Square Yards (225 square feet). Under this system, 20 Marlas make a 500 Gaj (4,500 square foot) Kanal.

However, the Punjab Department of Revenue (PLRS) and the Haryana Department of Revenue historically maintain ancestral land records (the Jamabandi and Fard) based on the linear Karam (5.5 feet / 66 inches). Under revenue law:

1 Karam: 5.5 feet
1 Sarsahi: 1 Karam × 1 Karam = 30.25 square feet
1 Traditional Revenue Marla: 9 Sarsahi = 272.25 square feet (30.25 Gaj)
1 Traditional Revenue Kanal: 20 Marlas = 5,445 square feet (605 Gaj)
1 Acre / Killa: 8 Kanals = 160 Marlas = 43,560 square feet (4,840 Gaj)

If you are acquiring land on the fringes of Kharar, Banur, Dera Bassi, or Landran that has not yet undergone formal municipal plotting or CLU (Change of Land Use), the title deed may reference shares (hissadari) of a revenue Kanal. In contrast, urban registry deeds inside approved colonizer layouts specify the exact area in square yards (Gaj) and square feet. Buyers reviewing plot values can compare regional land pricing in our analysis of the GMADA 2026 e-auction results in Aerocity and Sector 62.

Urban Planning Standard vs Agricultural Revenue Record System in Punjab & Haryana
Measurement Unit	Urban GMADA / PUDA Standard	Traditional Revenue Record (Jamabandi / Fard)	Variance in Square Feet	Practical Impact on Buyers
1 Marla	25 Gaj (225 sq ft)	30.25 Gaj (272.25 sq ft)	+47.25 sq ft (21% larger in revenue)	Urban plots are smaller per Marla than revenue shares
4 Marla Plot	100 Gaj (900 sq ft)	121 Gaj (1,089 sq ft)	+189 sq ft	Check whether registry says "100 Gaj" or "4/160th share"
8 Marla Plot	200 Gaj (1,800 sq ft)	242 Gaj (2,178 sq ft)	+378 sq ft	Standard 30x60 ft plot matches urban 200 Gaj
10 Marla (Half Kanal)	250 Gaj (2,250 sq ft)	302.5 Gaj (2,722.5 sq ft)	+472.5 sq ft	HSVP Panchkula plots often allot closer to revenue size
1 Kanal	500 Gaj (4,500 sq ft)	605 Gaj (5,445 sq ft)	+945 sq ft (21% larger in revenue)	GMADA allotments measure 500 sq yd; rural deeds measure 605 sq yd

Plot Dimensions Broken Down: Frontage, Depth, and Setbacks

Total area in Gaj determines how much land you own, but frontage determines what you can build. In the Tricity, municipal building bylaws govern how much ground coverage, Floor Area Ratio (FAR), and front and rear open setbacks are permitted based on your plot front.

1. The 100 Gaj Plot (900 Square Feet)

The most common residential dimension for a 100 Gaj plot in Kharar (such as Sunny Enclave) and Zirakpur is 20 feet front by 45 feet depth. A 20-foot frontage allows for a single dedicated car porch (approx. 9.5 to 10 feet wide) alongside a formal entrance lobby. On corner locations, 100 Gaj plots may appear as 30 feet by 30 feet, which provides generous natural light across two external walls but reduces private backyard depth. For budget buyers exploring emerging housing corridors, read our analysis on new launch projects in Zirakpur, Dera Bassi, and Kharar.

2. The 150 Gaj Plot (1,350 Square Feet)

A standard 150 Gaj plot measures 25 feet front by 54 feet depth (or occasionally 30 feet by 45 feet). That additional 5 feet of frontage compared to a 100 Gaj unit makes a substantial architectural difference: it enables a dual-car portico (or a car porch plus a separate garden entryway) and allows two full-sized bedrooms with attached washrooms on each upper floor.

3. The 200 Gaj Plot (1,800 Square Feet)

The 200 Gaj parcel is the benchmark residential plot size in GMADA Aerocity, IT City, Sector 82 JLPL, and Eco City New Chandigarh. The official standard dimension is 30 feet front by 60 feet depth. A 30-foot front easily accommodates two parked cars inside the gate, a grand central entrance, and a 6-foot front lawn setback as mandated by PUDA and GMADA building bylaws.

4. The 250 Gaj Plot (2,250 Square Feet / Half Kanal)

The 250 Gaj plot measures 30 feet front by 75 feet depth (or 35 feet by 64.3 feet in select private colonizer blocks). The 75-foot depth provides ample space for a 10-foot front setback, a central double-height living hall, and a mandatory 8-foot rear ventilation courtyard.

5. The 500 Gaj Plot (4,500 Square Feet / 1 Kanal)

The hallmark of upscale living in Chandigarh, Panchkula, and Mohali Sectors 68 to 71 is the 1 Kanal plot. In GMADA sectors, it measures exactly 50 feet front by 90 feet depth. With a 50-foot road frontage, builders construct sprawling kothis featuring 3-car stilt parking, a lush front lawn, servant quarters, and expansive 4BHK or 5BHK layouts across multiple levels.

The Irregular Plot Trap: How Brokers Overcalculate Area

Not every plot is a clean rectangle. When purchasing corner plots, cul-de-sac plots, or boundary parcels near village tracks, one or more sides often taper.

Unscrupulous brokers frequently use the Average Dimension Method to calculate area. If a plot has a front of 30 feet, a back of 20 feet, a left depth of 60 feet, and a right depth of 50 feet, they calculate:

Broker Formula: ((30 + 20) / 2) × ((60 + 50) / 2) = 25 × 55 = 1,375 square feet (152.7 Gaj)

This formula is mathematically invalid for non-rectangular quadrilaterals unless opposite angles sum exactly to 180 degrees. For skewed plots, the average method overstates the true usable surface area by 40 to 90 square feet. At prevailing Mohali or Zirakpur land prices of ₹50,000 to ₹90,000 per Gaj, this mathematical distortion costs buyers between ₹2,00,000 and ₹4,50,000 for land that does not exist.

What Smart Plot Buyers Verify

Triangulation Method: Dividing irregular boundaries into two triangles and measuring the diagonal directly.
Registry in Square Yards: Ensuring the Sub-Registrar conveyance deed lists exact Square Yards and Square Feet.
Physical Demarcation: Requesting official Nishandehi from a licensed revenue patwari using iron pegs.
Town Planning Setbacks: Confirming minimum mandatory front, rear, and side open spaces under GMADA or HSVP rules.
Verified Listings on Hoomzz: Browsing physically inspected plots and direct seller properties on Hoomzz.

Costly Plot Buyer Mistakes to Avoid

Average Dimension Multiplication: Averaging irregular fronts and depths without measuring diagonals.
Oral "Marla" Assurances: Assuming a seller's "4 Marlas" means 1,089 sq ft when it is actually 900 sq ft.
Unchecked Fard Shares: Buying an agricultural share (hissadari) without partition (takseem) or mutation.
Ignoring Road Widening: Failing to verify whether future master plan road widenings cut through the front lawn.
Unregistered Middlemen Deals: Paying cash advances before inspecting the chain of title deeds back thirty years.

Step-by-Step: How to Verify Plot Size Before Paying Token Money

Follow this checklist before releasing token money (biyana) for any plot across the Tricity:

Inspect the Original Allotment Letter and Zoning PlanDemand the official allotment letter issued by GMADA, HSVP, or the approved private colonizer. Check the specific zoning sheet for exact dimensions, building height caps, and permissible ground coverage.
Measure the Boundaries with a Steel Tape on SiteNever rely on pacing or digital step counts. Measure the front, rear, and both side boundaries with a 100-foot steel tape. If the plot is non-rectangular, measure corner-to-corner diagonal distances to calculate area via triangulation.
Check the Revenue Demarcation (Nishandehi)For unplotted or boundary land, file for official demarcation through the local Tehsil office. A revenue field officer inspects the village Aks Shajra (revenue map) and sets permanent boundary pillars (burjis).
Confirm the Area Unit in the Sale Agreement (Iqrarnama)Draft the agreement to sell specifying the exact area in both Square Yards (Gaj) and Square Feet. Avoid ambiguous clauses that reference "approximate area" or "area as per spot inspection."
Verify Ownership Records on State PortalsFor Mohali and Kharar, verify the current title holder on the Punjab land records portal (Jamabandi Punjab). For Panchkula, verify records via the Haryana Jamabandi portal to ensure no encumbrances, bank mortgages, or court injunctions exist.

Building and Renting in the Tricity: Transitioning from Plot to Rental Yield

Many investors acquire 100 to 250 Gaj plots in Mohali or Zirakpur with the explicit intention of constructing independent floors or kothis for rental income. Understanding regional property appreciation patterns is key; evaluate regional macro performance in our report on Tricity named among India's hottest property markets.

Once construction is complete, landlords must navigate regional tenancy regulations across state lines:

Chandigarh (UT): Tenancies are governed by the East Punjab Urban Rent Restriction Act, 1949. Although the central government issued a notification extending the Assam Tenancy Act, 2021 to Chandigarh on 6 May 2026, the Punjab & Haryana High Court stayed that notification on 29 May 2026, keeping the 1949 statute active.
Mohali, Kharar & Zirakpur (Punjab): Governed by the Punjab Rent Act, 1995.
Panchkula (Haryana): Governed by the Haryana Urban (Control of Rent and Eviction) Act, 1973.
Security Deposit Practice: There is no statutory two-month security deposit cap in force anywhere in the Tricity. Market practice remains 1 to 2 months rent for semi-furnished units, subject to mutual landlord-tenant agreement.
Mandatory Police Verification: Tenant police verification is mandatory in both Chandigarh and SAS Nagar (Mohali) districts under standing District Magistrate preventive orders.

Frequently Asked Questions

How many square feet is exactly 1 Gaj in Punjab and Haryana?

In Punjab, Haryana, and Chandigarh real estate, 1 Gaj equals exactly 9 square feet (which is identical to 1 square yard). It also converts to 0.836127 square metres. To convert any plot size from Gaj to square feet, simply multiply the number of Gaj by 9. For example, a 150 Gaj plot equals 1,350 square feet.

What are the standard front and depth dimensions of a 100 Gaj plot (900 sq ft)?

The most common dimension for a 100 Gaj plot across Kharar and Zirakpur is 20 feet front by 45 feet depth, totaling 900 square feet. This layout provides space for a dedicated car porch and entry lobby. In corner locations or select planned sectors, 100 Gaj plots may measure 30 feet by 30 feet or 22.5 feet by 40 feet.

How many Gaj make a 1 Kanal plot in Mohali?

In urban GMADA and PUDA developments across Mohali, 1 Kanal equals exactly 500 Gaj (500 square yards), which translates to 4,500 square feet or 20 urban Marlas. However, in traditional rural Punjab revenue records (Jamabandi fard), 1 agricultural Kanal equals 605 Gaj (5,445 square feet). Buyers must always verify which definition governs their plot.

What is the difference between Square Yard and Gaj in property registry?

There is no mathematical difference between a Square Yard and a Gaj in Indian property transactions; they share an exact 1:1 ratio. Both equal 9 square feet or 0.8361 square metres. While local brokers and vernacular documents use the term Gaj, official Tehsil sub-registrar conveyance deeds and municipal allotment letters generally use the formal English term Square Yard.

How do I calculate the total square footage of an irregular-shaped plot?

To accurately calculate the area of an irregular or tapered plot, divide the plot into two distinct triangles by measuring the diagonal distance between opposite corners. Next, calculate the area of each triangle using Heron's formula based on its three boundary sides, and sum the two areas. Never use the broker shortcut of multiplying average front by average depth, as that formula artificially inflates plot size.

Why is a Marla in GMADA Mohali different from a Marla in rural Punjab revenue records?

GMADA and PUDA standardized the urban Marla to 25 Square Yards (225 square feet) to make municipal planning and zoning calculations straightforward. In contrast, historical Punjab revenue records base measurements on a 5.5-foot Karam, defining 1 Marla as 9 Sarsahi (272.25 square feet or 30.25 Gaj). As a result, an agricultural revenue Marla is 21% larger than an urban GMADA Marla.
