Houses are growing larger every year as Americans attempt to outdo neighbors and friends and to spend more and more income on housing “things”. Interestingly family members living under one roof had been declining for 160 years, until the slight uptick this decade**. Interesting.
The average master bedroom size in the US in 2013 was 309 square feet. This was an estimated increase of 12.4% since 2003 and 44.7% since 1983. If the trend continues master bedrooms are going to be 492 square feet in another 40 years. Sound ridiculous? So did 309 square feet in 1983.
Table 1. Average master bedroom size in feet
1. National Association of Home Builders. Source: average percentages appended on special questions appended to the survey for the NAHB Fargo Housing Market Index, June 2013.
** Based on averages of all homes in the US.
Table 2. Average house sizes growth
*** Bedroom size from Table 1 and bedroom average size of room percent of the total house in 2013 is 11.8%.
So at this rate in another 40 years, master bedrooms will be 491.6 square feet, which is about 20 x 25′, or what I would consider a tiny home mansion. Maybe there will be a Monster King bed then that is 15′ wide by 12′ long.
