Right now I'm in the suburbs of Helsinki, and the Prisma hypermarket in the nearby mall is 19600 square meters (~210k square feet). About 1/3 of that is for groceries and 2/3 for everything else. Some of the bigger malls have two or even three competing hypermarkets, though they are usually not as large as the one we have here. We don't have a Walmart where I live in the US, and the nearest Target is only ~100k square feet.
