Land Measurement Units in India: Bigha, Sq Yard & More

You found your dream plot. The seller says it is "2 Bigha". Your sale deed says "0.81 Acre". The government record shows "32 Guntha". And your friend who bought nearby says his plot was measured in "square yards".

Are these the same thing? Completely different? Roughly similar?

If you have ever been confused by India's land measurement units — you are not alone. India uses over 20 different units to measure land, and the same unit (like Bigha) can mean completely different sizes in different states.

As property brokers who have helped 2,500+ families buy land in Ahmedabad and Gandhinagar, we get this question every single day. This guide explains every major land measurement unit used in India — with exact conversions, a Gujarat-specific section, and a master conversion table you can bookmark.

Why Does India Have So Many Land Measurement Units?

Before the metric system arrived, every region of India measured land in ways that made practical sense locally — a Bigha was roughly the area one farmer could plough in a day, a Guntha came from British survey ropes, and a Gaj was simply a square yard used in North Indian bazaars.

After Independence, the metric system (square metres, hectares) became legally official. But old habits in land dealings die hard. Today:

• Urban areas mostly use Square Feet (sq ft) and Square Yards (sq yd / Gaj)
• Agricultural land is measured in Acres, Bigha, Guntha, or Hectare
• Government records in Gujarat officially use Hectares and Square Metres
• Everyday transactions in Gujarat still use Vigha, Guntha, and Var

Let us go through each unit one by one.

Part 1: Universal / Standard Units

These are used across India and internationally. They are the units you will see in RERA documents, bank valuations, and government records.

1. Square Foot (sq ft)

The most common unit for residential property in India.

One square foot is the area of a square measuring 1 foot on each side. It is the standard unit for measuring flats, apartments, and small plots across urban India.

When you'll see it: Every apartment listing in Ahmedabad, Mumbai, Delhi. RERA mandates carpet area in sq ft.

Quick tip: A standard 2 BHK flat in Ahmedabad is typically 900–1,200 sq ft. A 30×40 plot = 1,200 sq ft.

2. Square Metre (sq m)

The legally official unit of land measurement in India since 1957.

The metric unit. All government land records, RERA documents, and official registrations use square metres.

When you'll see it: Sale deeds, registration documents, government survey records, municipal building plans.

3. Square Yard (sq yd) — also called Gaj or Var

The everyday unit for plots and open land in urban North and West India.

One square yard = 3 feet × 3 feet = 9 square feet. In Gujarat, this is called Var. In North India (Delhi, UP, Haryana), it is called Gaj. In parts of Andhra Pradesh, it is called Gajam.

When you'll see it: Plot listings in Ahmedabad, Delhi NCR property ads. In Ahmedabad, urban plots are often quoted in Var.

Real example: A 200 Var plot in Ahmedabad = 200 × 9 = 1,800 sq ft.

4. Acre

The standard unit for agricultural and large land deals across all of India.

One of the oldest and most widely recognised units globally. In India, an acre is used for farmland, large residential layouts, and commercial land parcels.

When you'll see it: Agricultural land deals, township layouts, large commercial plots.

Visualise it: One acre is roughly the size of a standard cricket outfield (the circular boundary). Or picture about 16 standard 2,700 sq ft residential plots side by side.

5. Hectare

The metric unit for large land — farms, government land, forests.

Used internationally and in India for agricultural land, forests, and large-scale government projects. Less common in everyday buying/selling.

When you'll see it: Government land records, agricultural loan papers, large farmhouse deals.

Visualise it: One hectare is slightly larger than an international football (soccer) pitch including the surrounding area.

Part 2: Gujarat-Specific Land Measurement Units

If you are buying or selling land in Ahmedabad, Gandhinagar, Surat, Vadodara, or anywhere in Gujarat — these are the units you will encounter most in everyday dealings. Even though official records use metric units, Vigha, Guntha, and Var dominate every actual transaction in Gujarat.

6. Vigha (Bigha in Gujarat)

The most important traditional unit in Gujarat.

In Gujarat, Bigha is pronounced and written as Vigha. It is the primary unit for agricultural land and large residential plots in rural and semi-urban Gujarat.

⚠️ Caution — regional variation: The size of one Vigha differs by region in Gujarat:

Standard conversions for most of Gujarat (20 Guntha Vigha):

Standard conversions for Saurashtra (16 Guntha Vigha):

When you'll see it: Every agricultural land deal, large plot sale, and rural land transaction in Gujarat. When you see "2 Vigha farmland" in a listing — it means approximately 1 Acre (for Ahmedabad region).

Pro tip from Rama Realty: Always ask the seller and confirm in local revenue records (7/12 Utara, 8-A) which Vigha measurement is being used. The difference between a 16-Guntha and 20-Guntha Vigha on a 5-Vigha plot is over 21,780 sq ft — roughly the size of 2 additional residential plots.

7. Guntha (also spelled Gunta)

The base unit for mid-size land in Gujarat, Maharashtra, and Karnataka.

One Guntha = 33 feet × 33 feet = 1,089 sq ft. It is the most precisely defined traditional unit in Gujarat and does not vary by region the way Vigha does. This makes it one of the most reliable units for pricing and negotiation.

When you'll see it: Medium-sized agricultural plots, semi-urban residential land, layout plots in Gandhinagar and surrounding areas.

Visualise it: One Guntha is roughly the size of a badminton court (44 × 20 ft = 880 sq ft) — just slightly larger.

8. Var (Square Yard in Gujarat)

The standard unit for urban residential plots in Ahmedabad, Surat, and Vadodara.

Var is simply the Gujarati name for square yard. 1 Var = 9 sq ft. In Ahmedabad's property market, residential plots in developed areas, housing societies, and city layouts are almost always quoted in Var.

When you'll see it: Urban plot listings in Ahmedabad, society plot advertisements, redevelopment scheme documents.

Real example: "200 Var plot near SG Highway" = 200 × 9 = 1,800 sq ft. At ₹8,000 per Var, the plot cost = ₹16 lakhs.

9. Biswa (Biswansi)

A sub-unit of Vigha used in North Gujarat and Rajasthan.

In Gujarat and Rajasthan, 1 Vigha = 20 Biswa. Biswa is used mostly in older land records and agricultural documentation in North Gujarat districts like Mehsana, Banaskantha, and Patan.

When you'll see it: Old land records, ancestral property documents, agricultural land in North Gujarat districts.

Part 3: Other Regional Units Across India

These units are not typically used in Gujarat but you may encounter them if you are investing in property in other states, or reading about pan-India real estate.

10. Bigha (Other States)

Bigha is the same concept as Gujarat's Vigha but the size varies drastically across states. Here is a state-wise breakdown:

⚠️ Never assume one Bigha is the same as another. A "5 Bigha" farm in Rajasthan is more than twice the size of a "5 Bigha" farm in Assam.

11. Katha (Kattha)

Primarily used in Eastern India — Bihar, Jharkhand, West Bengal, and Assam.

20 Katha = 1 Bigha in most Eastern states.

12. Marla

Used primarily in Punjab, Haryana, and Himachal Pradesh.

13. Kanal

A unit used in Punjab, Haryana, Himachal Pradesh, and Jammu & Kashmir.

14. Cent

Used mainly in South India — Tamil Nadu, Kerala, Karnataka, Andhra Pradesh, Telangana.

Think of a Cent as exactly 1/100th of an Acre. The name literally means "one-hundredth."

15. Ground

Used in Tamil Nadu for residential plots.

16. Ankanam

A small unit used in Andhra Pradesh and Karnataka.

Part 6: How to Check Land Measurement in Gujarat — Official Records

When you buy land in Gujarat, the area is mentioned in these official documents:

7/12 Utara (Satbara) — The primary land record in Gujarat, maintained by the Talati. Shows the area in Hectares and Ares. You will need to convert to Vigha/Guntha for practical understanding.

8-A Record — Shows the rights and ownership. Area also in metric units.

Property Registration Document (Sale Deed) — Usually in Sq Metres as per registration requirement. Always cross-verify with the 7/12.

RERA Project Documents — Always in Sq Metres and Sq Feet.

How to convert 7/12 area to Vigha:

• 1 Are = 100 Sq Metres
• 1 Hectare = 100 Ares = 10,000 Sq Metres
• 1 Vigha (Gujarat, 20 Guntha) = 0.2023 Hectare = 20.23 Ares

So if your 7/12 shows 1.00 Hectare:

= 1 ÷ 0.2023 = ~4.94 Vigha = ~40 Guntha = 2 Acres

Part 7: 5 Common Mistakes Property Buyers Make With Land Measurements

Mistake 1: Assuming Bigha is the same size everywhere

The most dangerous mistake. A "5 Bigha" plot in Rajasthan (1,36,125 sq ft) is nearly 6× larger than a "5 Bigha" plot in Punjab (45,350 sq ft). Always confirm which state's Bigha is being referred to.

Mistake 2: Confusing Vigha sizes in Gujarat

Even within Gujarat, the 16-Guntha Vigha (Saurashtra) and the 20-Guntha Vigha (most of Gujarat) differ by 25%. On a 10-Vigha deal, this is a difference of 43,560 sq ft — one entire Acre.

Mistake 3: Not cross-checking with 7/12

Sellers often quote traditional units loosely. Always convert the seller's quoted Vigha/Guntha to Sq Metres and verify against the 7/12 Utara. The official record is the legal truth.

Mistake 4: Confusing carpet area, built-up area, and super-built-up area for flats

For flats and apartments, three different areas are quoted:

• Carpet Area — The actual usable floor area inside walls. The only area RERA recognises for pricing.
• Built-up Area — Carpet area + wall thickness (~10–15% more than carpet area)
• Super Built-up Area — Built-up area + proportional share of common areas like lobby, staircase, lift. Often 25–30% more than carpet area.

When comparing flats, always compare carpet area, not super built-up area.

Mistake 5: Using online converters without selecting the correct state

Most generic online land converters use a single Bigha value. For Gujarat, always use a Gujarat-specific converter that distinguishes between Saurashtra and North/South Gujarat Vigha values.

Part 8: Frequently Asked Questions

In Gujarat (most regions), 1 Vigha (Bigha) = 21,780 sq ft (20 Guntha). In Saurashtra, 1 Vigha = 17,424 sq ft (16 Guntha).

Q: 1 Guntha is equal to how many square feet?

1 Guntha = 1,089 sq ft across India. This is one of the few traditional units that is consistent nationwide.

Q: 1 Acre is equal to how many square feet?

1 Acre = 43,560 sq ft = 4,840 sq yd = 4,046.86 sq m.

Q: 1 Sq Yard (Gaj / Var) is equal to how many sq ft?

1 Sq Yard = 9 sq ft. Always. This never varies.

Q: How many Guntha in 1 Vigha in Ahmedabad?

In Ahmedabad and most of Gujarat: 1 Vigha = 20 Guntha. In Saurashtra: 1 Vigha = 16 Guntha.

Q: How many Vigha in 1 Acre in Gujarat?

In most of Gujarat (20-Guntha Vigha): 1 Acre = 2 Vigha.

In Saurashtra (16-Guntha Vigha): 1 Acre = 2.5 Vigha.

Q: What is the difference between sq yard and sq foot?

1 sq yard = 9 sq feet. A yard is 3 feet, so a square yard is 3×3 = 9 sq ft.

Q: What units does the Gujarat government use for official land records?

All Gujarat land records (7/12 Utara, 8-A) officially use Hectares and Ares (metric system). However, Vigha, Guntha, and Var are still commonly used in sales and mutations.

Q: What is the meaning of "100 Var plot"?

100 Var = 100 sq yd = 900 sq ft. This is a small plot typically used for a single-room or compact house in Gujarat.

Q: What is a Dismil in land measurement?

Dismil (also Decimal) = 1/100th of an Acre = 435.6 sq ft. Commonly used in Jharkhand, Bihar, and West Bengal. Same as a Cent in South India.

Q: How is land measured for agricultural loans in Gujarat?

Banks and government schemes (PM-Kisan, iKhedut) calculate land area from the 7/12 Utara record in Hectares. Always carry a certified copy of your 7/12 when applying.

Summary: The 60-Second Cheat Sheet

If you remember nothing else from this guide, remember these six conversions:

1 Sq Yard (Var/Gaj) = 9 Sq Feet

1 Guntha = 1,089 Sq Feet (= 121 Sq Yd)

1 Vigha (Gujarat) = 20 Guntha (= 21,780 Sq Ft in most of Gujarat)

1 Vigha (Saurashtra) = 16 Guntha (= 17,424 Sq Ft)

1 Acre = 43,560 Sq Ft (= 40 Guntha = 2 Vigha in Gujarat)

1 Hectare = 2.471 Acres (= 10,000 Sq Metres)

And one golden rule: always verify measurement against the official 7/12 record before signing any property agreement in Gujarat.
