It's kind of mad that the US houses are an average of 2000 square feet, yet if you watch some of the "New York apartment tour" videos on YouTube they are often far smaller than even what you'd find in London. The kitchens are often absolutely pitiful little spaces, especially considering the multi-thousand-dollar rents.

If you’re in downtown or midtown they’re small. I lived in Washington Heights (north Manhattan) for a few years and my apartment was two bedrooms with a relatively big living area, and I was able to afford that with an academic’s salary. I don’t remember the exact square footage but my wife and I lived there and it didn’t feel cramped at all. I own a house in Brooklyn now and if you count the basement it’s about 1600sqft.

Though York is a fairly rural town, and houses/apartments that small in rural America, as far as I am aware, are basically unheard of.
