Compared to other countries, America is known for bigger cars, portions and take-out coffee cup sizes. For most of recent history, Americans have also wanted bigger homes — but now that’s changing.

For most of the last half-century, new single-family homes kept growing. In 1973, the median size of completed single-family homes was 1,525 square feet, according to US Census data. By 2015, that number had ballooned to 2,467 square feet.
