how big is canberra

Canberra covers roughly 800–815 square kilometres, or about 310–315 square miles.

For a bit more feel for that size:

• One estimate puts Canberra’s area at about 805.6 square kilometres (311 square miles).

• Other recent descriptions round it to about 814 square kilometres (314 square miles).

• That makes it a relatively spacious capital city, with a lot of its area taken up by bushland, parks, and open space rather than dense high‑rise development.

So if you imagine a roughly circular city, Canberra’s footprint is similar to a large metropolitan area but with fewer people and more green space spread across that land.
