The world’s largest shopping mall is the Iran Mall a.k.a. The Grand Bazaar of Iran. It opened in 2018 in Tehran and will have 21 million square feet of leasable space when completed.
The King of Prussia Mall — which Wikipedia cites as America’s largest shopping mall due to a 2016 renovation albeit you will certainly get an argument — has 2.793 million square feet of leasable space.
