How big is Dholera smart city?

Updated 22 July 20265 min readSourced and dated
The short answer

Dholera's total planning envelope is about 920 sq km, roughly 360 sq mi, which is often quoted to make it sound larger than several major cities. The honest breakdown matters: only about 580 sq km is developable and around 422 sq km is urban, while roughly 370 sq km falls in the Coastal Regulation Zone. The part that actually exists today, the Activation Area, is only about 22.5 sq km. So Dholera is enormous on paper and small on the ground, with the gap being the phased build-out to around 2040.

The number you will see everywhere is 920 sq km, and it is technically correct but easy to misread. That figure is the planning envelope, the outer boundary of the Special Investment Region, not the amount of city that is built or even buildable. Understanding the difference between the plan and the ground is the single most useful thing a buyer can learn about Dholera's size.

The full breakdown

The total planned area is about 920 sq km, roughly 360 sq mi. Of that, around 580 sq km is developable and about 422 sq km is urban-developable. Roughly 370 sq km falls within the Coastal Regulation Zone, which constrains what can be built there. The city is being delivered in three phases over roughly 30 years, so at any given moment only a fraction of the envelope is active. Our master plan guide explains how the six Town Planning schemes carve up that area.

How much actually exists

The part of Dholera that is built and serviced today is the Activation Area, about 22.5 sq km, recorded by NICDC as 22.54 sq km. That is roughly 4.25 percent of the developable land. It holds the trunk infrastructure, the command centre and the semiconductor fab. So the working answer to "how big is Dholera" has two numbers: about 920 sq km planned, and about 22.5 sq km real. Both are true, and quoting only the first is how brochures inflate the story.

On the superlatives. Claims that Dholera is "the biggest greenfield city in India or the world" are unverified superlatives. The 920 sq km is a planning envelope, not a finished footprint, and only around 422 sq km is urban-developable over a 30-year phasing. Treat size claims as ambition, not achievement.

How to picture it

At 920 sq km, the envelope is larger than many major Indian cities by area, which is why the ambition is real. But a low-lying coastal site with a large Coastal Regulation Zone share and a 30-year phasing means the lived city will grow gradually from the Activation Area outward. For buyers, the practical takeaway is that location within this vast envelope matters enormously: a plot near the built 22.5 sq km is a different asset from one in the far, unbuilt reaches.

The bottom line

Dholera smart city is about 920 sq km on paper, about 422 sq km urban-developable, and about 22.5 sq km built so far. The scale of the plan is genuine and the ambition is national, but the finished city is early and concentrated. Judge any plot by its distance from the built zone, not by the headline area, and read the phases and timeline to see how the rest is meant to fill in.

Frequently asked questions

How many square kilometres is Dholera smart city?
The total planning envelope is about 920 sq km, roughly 360 sq mi. But only about 580 sq km is developable and around 422 sq km is urban-developable, with roughly 370 sq km in the Coastal Regulation Zone. The built Activation Area is only about 22.5 sq km.
Is Dholera really the biggest greenfield city in the world?
That is an unverified superlative. The 920 sq km is a planning envelope, not a finished footprint, and only around 422 sq km is urban-developable, phased over roughly 30 years. Treat biggest-in-the-world claims as marketing, not fact.
How much of Dholera is actually built?
The built and serviced part is the Activation Area, about 22.5 sq km, which is roughly 4.25 percent of the developable land. It holds the trunk infrastructure, command centre and semiconductor fab. The rest is planned and phased to around 2040.
Why is only part of Dholera developable?
The site is a low-lying coastal area on the Gulf of Khambhat, and roughly 370 sq km falls within the Coastal Regulation Zone, which limits construction. Of the 920 sq km envelope, about 580 sq km is developable and around 422 sq km is urban-developable.
