How big is the ISS?

Ok, this is kind of fun. We can see the ISS flying over our house every now and then, I've taken photos with the telescope, but how big is that thing?
This is kind of the geeky comparison, but gives a pretty good idea. Galactica is a pretty big ship!

ISS Size:

Mass: 300,214 kg (661,857 lb) (June 18, 2008)
Length: 58.2 m (191 ft) along truss (February 22, 2007)
Width: 44.5 m (146 ft) from Destiny to Zvezda
Height: 27.4 m (90 ft) (February 22, 2007)

Solar arrays span: 73.15 m (240 ft) (February 22, 2007)
