The graphic below is from the BBC (click here for the original article) showing a comparison of house sizes in different countries:


If you convert the square metres to square feet, you end up with:
US: 2,300
Australia: 2,217
Denmark: 1,475
France: 1,216 (roughly the size of an American double-wide trailer)
Spain: 1,044
Ireland: 947
UK: 818

Our house is very close to the Irish average. We have room for everything we need, just not enough room to accumulate lots of extras. That’s fine with us!
