Sand dunes in the Middle East can vary significantly in size, but many are quite large, reaching heights of up to 250 meters (820 feet) or more. The Rub' al Khali, or Empty Quarter, in Saudi Arabia is home to some of the tallest dunes in the world, with heights exceeding 250 meters. The vast expanses of desert in this region also feature extensive dune fields, often stretching for kilometers.

Larger dunes may indicate stronger winds, while smaller dunes may have been shaped by lighter winds. The shape of the dune can also give insight into the prevailing wind direction during its formation.
