Western being what exactly? Houses are rarely spacious in a lot of what qualifies as 'west'. You can't compare The Netherlands and Belgium with Germany, let alone the US.

Sorry I should have specified, I was referring to Aussie homes(my home country) or US. My bad.

But even then I'd probably guess Japanese are smaller. I have not looked at the numbers and will go look now though, I should have before commenting.

Edit: you're right(as I had assumed being familiar), Netherlands average from a quick search is roughly on par.
