FAR / FSI calculator for plots (Noida, Greater Noida, Ghaziabad, Gurgaon, Delhi)

FAR (floor area ratio), called FSI in some states, is the multiplier the authority allows on your plot area: a 200 sq m plot with FAR 2.75 may build 550 sq m of covered area. Ground coverage caps the footprint and setbacks fix where it can sit. Defaults below reflect common residential plot norms in Noida and Greater Noida; pick your city or edit the values from your sanctioned bye-laws.

Plot area Unit Permissible FAR / FSI Noida residential plots ≤ 300 sq m: 2.75; Greater Noida: 2.75–3.5; Ghaziabad GDA: ~2.5; Gurgaon HSVP: 1.98–2.64; Delhi (≤100 sq m): 3.5. Verify with your authority. Max ground coverage % Front setback (m) Rear setback (m) Side setback each (m) Plot frontage (m) Purchasable FAR (extra, if any)

Maximum built-up area (FAR)550.00 sq m

Same in sq ft: 5,920 sq ft
Max ground coverage footprint: 150.00 sq m
Buildable envelope after setbacks: 150.00 sq m
Usable footprint per floor (lower of the two): 150.00 sq m
Floors needed to use full FAR: 3.7 floors (G+3)

How it is calculated

built-up = plot × (FAR + purchasable FAR). The footprint is limited twice: by ground coverage (plot × coverage%) and by the envelope left after setbacks ((frontage − 2 × side) × (depth − front − rear), with depth = plot ÷ frontage). The smaller footprint divided into the built-up area gives the floors needed. Stilt parking, basements and services are often excluded from FAR; the bye-laws decide.

Worked example

A 200 sq m Noida plot with FAR 2.75 and 75% coverage: built-up 550 sq m (5,920 sq ft); footprint 150 sq m. With a 10 m frontage and 3 m front, 2 m rear setbacks the envelope is 10 × 15 = 150 sq m, so 550 ÷ 150 ≈ 3.7 floors: G+3 uses the FAR.

Frequently asked questions

What is the FAR for residential plots in Noida?

Noida Authority allows 2.75 on most residential plots up to 300 sq m with up to 75% ground coverage and stilt plus four floors in recent amendments; larger plots and group housing differ. Confirm the current building regulations for your sector before designing.

What is the difference between FAR and FSI?

None in substance: FAR is the term in north India (Delhi, UP, Haryana), FSI in Maharashtra and the south. Both equal permitted built-up area divided by plot area.

Does basement count in FAR?

Usually not when used for parking or services; habitable basements are often counted. Stilt parking is generally FAR-free. Check the bye-law clause for your authority.

Sources and what to verify: Noida / Greater Noida / Ghaziabad building regulations; Haryana (HBC) and Delhi (UBBL 2016) bye-laws: verify current amendments.
