How big is Islamabad? The answer depends on whether you mean the city or the territory — and most sources mix them up. The exact figures: 906.50 km² for the Capital Territory, 2.36 million people (2023 census), and all the comparisons that put the size in perspective.
Quick answer: Islamabad’s size: the Islamabad Capital Territory covers 906.50 km²; the urban city covers 220.15 km². Population (2023 census): 2,363,863 in the territory, 1,108,872 in the city — Pakistan’s 10th-largest city. With Rawalpindi, the metro area exceeds 5.7 million.
Area: Territory vs City
Two numbers, don’t mix them: the Islamabad Capital Territory spans 906.50 km² (350 sq mi) — including the Margalla Hills National Park, rural areas and Rawal Lake’s catchment — while the urban city covers 220.15 km². The territory was demarcated in the 1960s master plan (urban 220.15, Margalla Hills 220.15, rural 466.20 km²).
Population: 2023 Census
The 2023 census counted 2,363,863 people in the ICT (density ~2,608/km²) and 1,108,872 in the city proper — making Islamabad Pakistan’s 10th-largest city, far behind Karachi (~17M+) and Lahore (~13M+). Growth has been explosive: 237,549 in 1972 → 805,235 in 1998 → 2,003,368 in 2017 → 2,363,863 in 2023 (Pakistan Bureau of Statistics).
Size in Perspective
Islamabad’s territory is roughly 1.5 times the size of Karachi’s urban core in area but holds a seventh of its people — the capital is deliberately low-density. Its metro (with Rawalpindi) tops 5.7 million, and its elevation (666m, up to 1,584m in the Margallas) makes it Pakistan’s highest major city. See the region’s geography.
How Fast It’s Growing
At ~2.8% annual growth (2017–2023), the ICT adds a small town every year — mostly in the private housing societies (DHA, Bahria Town) spilling beyond the original sectors. The master plan’s southwest expansion corridor is where the next million will live. The city overview: Islamabad pillar.
