The big houses are REALLY big. And, while I can find a small apartment, new homes under 2000 sq ft are tough to find. The house I grew up in was 1500 sq ft and plenty for a family of four. I wish I could own a 1100 or less sq ft home but they’re all very old
I suspect that something has changed in the way square footage is calculated. Perhaps there are more finished basements or something. I was very involved in several moves my family undertook when I was younger. I feel like I got a good sense for home sizes. Many of the ones listed for 3000 sq ft. today look more like the 2000 sq ft. houses from yesteryear.
I also think about Louis Rossmann's quest to find a NYC storefront for his repair business a few years ago. He brought a laser measure with him, to document how the actual space squared with advertisements. I don't know that he ever found a place that wasn't lying. Yes, New York and, yes, commercial, but I wouldn't be surprised to see similar tactics in place for residential, across the country.
Almost all of the middle class tract homes built in California (for example) in the 60s/70s are around 1200sf. They also used cheap materials, had no insulation, maybe 2 bathrooms but often 1.5, very simple kitchens, etc.
The stuff that people buy now are much bigger and much more luxurious even at the bottom end.
