Apartment sizes on the rise after decade-long shrinking trend

The average size of new apartments in the U.S. saw substantial growth in 2023, bouncing back to 916 sf after a steep decline the previous year. That is according to a recent RentCafe market insight report released this month.

The growth in average apartment size can be attributed to the influx of two- and three-bedroom units coming on the market. In cities like Jacksonville and Orlando, Fla., large apartments lead the pack, while metros like Seattle, Wash., lead the top 100 metros in smallest unit sizes.

10 Year History of Average Apartment Size Changes

For the past 10 years, the average size of multifamily housing units have been steadily shrinking. This is driven by one-bedroom apartments that dominate the landscape, comprising nearly half (48%) of all apartments built in 2023.
