During the recession, Americans downsized and the average new home shrunk in size by 6% over two years to 2,135 square feet. At the time, many industry experts said the days of the McMansion were over, writes CNNMoney.

However, in 2012 the National Association of Home Builders conducted a survey of homebuyer preferences and found that people preferred a median home size of 2,226 square feet, just shy of the U.S. Census Bureau's recently reported median size.

And the homes seem to be getting even bigger this year, according to builders. Marcie DePlaza, a division president for GL Homes, said so far this year her company is selling homes that average about 7% larger than during the first five months of 2012.
