If asked, the majority of people might say that the Dubai-based Burj Khalifa is the largest building in the world. However, there are several other yardsticks to use when analyzing the biggest buildings. One of these is the size regarding floor area. By land area, the New Century Global Center in Chengdu, China is the world's largest building. It covers a total of 18.9 million square feet. The Dubai International Airport Terminal 3 is a close second with 18.4 million square feet covered.

Shopping malls discourage tall buildings due to tenancy issues where most tenants would prefer bottom floors so as to be easily seen by their customers.
