Gaj to Square Meter: North India's Property Unit Decoded

Gaj (or gaz) is the dominant property unit in North India — you'll find it in Delhi, Haryana, Punjab, and UP real estate listings. Here's how it converts to sq ft, sq meter, and internationally recognized units.

1.What is a gaj and where it is used

Gaj (also spelled gaz or guz) is a traditional South Asian unit of measurement equivalent to 1 yard = 3 feet = 0.9144 meters. As a square unit: 1 sq gaj = 1 sq yard = 9 sq ft = 0.836 sq meters. Gaj is the standard unit for property plots in North India: Delhi Development Authority (DDA) allocates plots in sq gaj (a "200 sq yard plot" = 200 sq gaj = 1,800 sq ft). Haryana Real Estate Regulatory Authority (HRERA) lists properties in sq gaj. UP RERA uses sq ft but sellers and brokers colloquially use gaj. Understanding gaj is non-negotiable for buying or selling property in Delhi-NCR.

2.The essential conversion table

1 gaj = 1 square yard = 9 sq ft = 0.836 sq m. 25 gaj = 225 sq ft (1 marla). 100 gaj = 900 sq ft. 200 gaj = 1,800 sq ft. 300 gaj = 2,700 sq ft. 500 gaj = 4,500 sq ft. 1,000 gaj = 9,000 sq ft = 836 sq m = 0.0836 of an acre. A typical DDA LIG flat is built on a 50 gaj (450 sq ft) plot; a DDA MIG flat on 100 gaj (900 sq ft). In Gurugram (Gurgaon), residential plots are commonly listed as 200, 300, 500, or 1,000 sq gaj. A 200 sq gaj Gurugram plot in Sector 57 might cost ₹2.5 crore — knowing that's 1,800 sq ft helps compare against Mumbai listings in sq ft.

3.Gaj vs sq ft vs sq meter: which to use and when

Use sq ft for: comparing Indian properties across cities (Bangalore, Mumbai, Pune use sq ft). Apartment size comparisons. RERA certificates which now mandate sq ft or sq m. Use sq gaj for: North India residential plot transactions. DDA documents, Haryana HRERA, and local North Indian property registries. Use sq meter for: formal legal documents (recommended by BIS as the SI unit). International property comparisons. Architectural drawings and blueprints. The mismatch between sq gaj in the listing and sq ft in your head is where expensive errors happen — always convert before making a price-per-unit comparison between properties in different cities.

4.Price-per-gaj vs price-per-sq-ft: the common confusion in NCR

A Noida flat listed at "₹5,500 per sq ft" and a Delhi plot listed at "₹45,000 per gaj" seem incomparable. Converting: ₹45,000 per gaj = ₹45,000 per 9 sq ft = ₹5,000 per sq ft. Now they're comparable. Many North Indian sellers quote gaj to make their property seem cheaper in absolute numbers ("₹45,000 per gaj sounds like 45k per unit" vs "₹5,000 per sq ft also sounds like 5k per unit" — but the units are 9x different in size). Always convert both prices to the same unit (sq ft or sq m) before comparison. This is the most common arithmetic mistake in NCR property transactions.

5.Using our unit converter for property calculations

Our unit converter handles all common Indian land units: gaj to sq ft, sq ft to sq m, bigha to sq ft, guntha to sq ft, marla to sq gaj. For property purchase decisions: enter the total plot size in gaj from the listing, convert to sq ft using the converter, then compute price per sq ft by dividing total price by sq ft. Compare this per-sq-ft price to the CREDAI or magicbricks.com data for the same micro-market. If you're buying a 300 gaj plot (2,700 sq ft) at ₹80 lakh, your price is ₹2,962/sq ft — compare against neighboring registrations at the sub-registrar office (these are public record in most states) to validate the fair market price.
