The size of the average new apartment in the U.S. has risen in recent years, reversing a decade-long downward trend, but not all cities are seeing the uptick.
           
A new study from RentCafe found that in 2024, the average size of an apartment rose to 908 square feet, well below the 930 square feet average in 2015, the beginning of the decade. However, the 2024 figure was an improvement on the average of 903 square feet in 2023 and 891 square feet in 2022—the lowest level in the decade. The report considered the size of apartments across the 100 largest renter hubs in the U.S., as of February 2025. 

“The most substantial space gains are appearing in several Coastal and Sunbelt cities, giving renters more options for spacious living,” the report noted. Nationwide, the average size of all new apartments rose by four square feet. By unit type, studios grew to 457 square feet (up 13), one-bedrooms to 735 square feet (up six), and two-bedrooms to 1,097 square feet (up four). However, the average size of three-bedroom units fell 15 square feet to 1,336 – a response, the report said, to cases where location is more important than size.
