Fascinating size-comparison maps reveal how big cities REALLY are, with London TWICE the size of New York (and Paris is tiny when compared to both)
Britain may be a tiny country - but its capital city, London, packs a huge punch size-wise.
A fascinating size-comparison mapping tool that enables users to superimpose a map of one city over that of another reveals that it's actually bigger than all the cities with famous skylines in America.
The tool, by www.mylifeelsewhere.com, makes for a fascinating geography lesson, with the feature also revealing that some world-famous cities - such as Paris and Sydney - are surprisingly small.
In fact, they are both swallowed up by London and America's major metropolises.
We've picked out some of the most interesting comparisons and presented them below.
