Average House Size in the US

Updated 31 August 2026 · US Census Bureau Survey of Construction (new homes) + RentCafe / Yardi Matrix (apartments)

Quick answer

The median new single-family home in the US was 2,142 sq ft (199 m²) completed and 2,194 sq ft (204 m²) sold in 2025, per the US Census Bureau. That is down from a 2015 peak of about 2,467 sq ft (229 m²). The average apartment is about 910 sq ft (85 m²) (RentCafe, 2025). New single-family homes are what most people mean by average house size; the older existing stock averages less. US homes are roughly two and a half times the size of a typical UK new-build.

How US New-Home Size Has Changed

The median new single-family home grew steadily for four decades, peaked in 2015, and has eased back since as builders returned to smaller, more affordable homes. Figures are the median size of completed new single-family homes from the US Census Survey of Construction.

New Homes, Existing Homes, and Apartments

Average house size in the US means different things depending on the segment. The new single-family home is the headline number, and the one the Census tracks most closely: 2,142 sq ft (199 m²) completed in 2025. Because it counts only homes built that year, it reflects the largest, newest stock. About 42 percent of new single-family homes completed in 2024 had four or more bedrooms (US Census).

The existing housing stock is smaller, because it includes post-war ranch houses, mid-century split-levels, and city rowhouses alongside new construction. The American Housing Survey measures this all-stock figure; see the US row on our country table.

Apartments are smaller again, averaging about 910 sq ft (85 m²) across all unit types in 2025, and vary widely by city. See our apartment sizes by city page for New York, and the full US-by-type breakdown.

Frequently Asked Questions

What is the average size of a house in the US?

The median new single-family home built in the US was 2,142 sq ft (199 m2) as completed and 2,194 sq ft (204 m2) as sold in 2025, per the US Census Bureau's Survey of Construction. That is down from the 2015 peak of about 2,467 sq ft (229 m2). New single-family homes are the figure most people mean by average house size; the existing housing stock, which includes older and smaller homes, averages less.

How big is the average new home in the US?

In 2025 the median new single-family home was 2,142 sq ft (199 m2) when completed and 2,194 sq ft (204 m2) when sold (US Census Survey of Construction). New-home size peaked in 2015 at about 2,467 sq ft and has drifted down since, as builders shifted toward smaller and more affordable homes.

What is the average apartment size in the US?

The average US apartment was about 910 sq ft (85 m2) in 2025, per RentCafe's analysis of Yardi Matrix data. By type, studios averaged 457 sq ft (42 m2), one-bedrooms 735 sq ft (68 m2), two-bedrooms 1,095 sq ft (102 m2), and three-bedrooms 1,355 sq ft (126 m2). Apartment sizes grew again in 2025, extending a reversal of roughly a decade of shrinking floor plans.

Are US homes getting bigger or smaller?

New single-family homes peaked in 2015 at about 2,467 sq ft and have eased since, to 2,142 sq ft in 2025, a fall of roughly 13 percent, driven by more entry-level building and affordability pressure. Apartments have moved the other way, growing modestly for several years after a long period of shrinking. So the direction depends on which segment you mean.

How does the average US house compare with the UK?

US homes are far larger. The median new US single-family home (about 2,142 sq ft / 199 m2) is roughly two and a half times the size of a typical UK new-build (around 76 m2 / 818 sq ft), and about twice the UK all-stock average of 96 m2 (1,033 sq ft, English Housing Survey 2024-25). Lower land costs, looser planning, and car-dependent suburban development all push US home sizes up.

Why is the new-home figure different from the all-stock average?

The Census Survey of Construction measures homes built in a given year, so it tracks the newest, largest stock. The all-stock average, from the American Housing Survey, includes every home regardless of age, so older and smaller houses pull it down. Both are legitimate; they answer different questions. This page leads with the new-build median because that is what average house size usually refers to.
