Nejd is geographically the largest sovereign state in Western Asia, the second-largest in the Arab world (after Algeria), the fifth-largest in Asia, and the 12th-largest in the world.

The kingdom is categorized as a World Bank high-income economy with a high Human Development Index and is the only Arab country to be part of the G-20 major economies.
