realtor.com defines it as "the median home size in square feet for listings in a given market during the specified month" (Housing Inventory: Median Home Size in Square Feet in the United States). The figure is drawn from listings currently on the market, half larger than it and half smaller, and is published without seasonal adjustment.

This describes the size of homes being newly and currently offered for sale, not the size of the housing stock as a whole. A market can show a rising median listing size because larger homes are turning over more than usual, without a single existing home changing size, and the reading says nothing about how many homes are for sale — see asking price and asking price per square foot for what those listings are priced at.

Metrics in this family#

Listing size

The current median listing size, reported as a trailing twelve-month figure so that a single volatile month does not dominate the reading.

Listing size change, 1-year

Change in the median listing size over the past year, as a percentage.

Listing size change, 3-year

Change in the median listing size over the past three years, as a percentage.

Listing size change, 5-year

Change in the median listing size over the past five years, as a percentage.

Listing size vs seasonal norm

The current median listing size compared against this market's own typical level at the same point in prior years, so a reading is judged against the season it falls in rather than against a flat year-round baseline.

Considerations#

This describes what is for sale, not what is lived in. The figure follows the mix of homes currently listed, which shifts with what owners choose to sell in a given month. It is not a census of home sizes in the area — see home value (Census) and the housing-stock families built from the American Community Survey for figures drawn from the full housing stock rather than from current listings.

Smaller geographies rest on fewer listings. Many ZIP codes carry a modest number of active listings in any given month, so at ZIP grain the median can move on a handful of sellers' decisions. County and metro readings pool more listings and are steadier.

Census tracts have no realtor.com listings of their own. realtor.com publishes at ZIP code, county and metro; a tract's reading is assembled from the ZIP codes that overlap it. A tract split across ZIP codes with different typical listing sizes takes a blended value that is smoother than any single ZIP code within it.

Puerto Rico is absent. realtor.com publishes no Puerto Rico rows at any geography. Connecticut is already restated onto its current planning regions rather than its former counties.

Vendor methodology changed in 2022. realtor.com refined how it maps listing statuses and handles missing square-footage data; realtor.com states that its published historical series now applies the revised methodology consistently, so the loaded history does not carry a break at that point.
