Persian Gulf Dimensions: Length, Width, and Key Facts

The Persian Gulf is a mediterranean sea in Western Asia, extending between Iran and the Arabian Peninsula. Its dimensions:

• Length: ~989 km (615 miles)
• Maximum Width: ~338 km (210 miles) — between Iran and the Arabian Peninsula
• Average Depth: ~35 meters (115 feet)
• Maximum Depth: ~90 meters (295 feet)
• Surface Area: ~251,000 km² (97,000 sq mi)

Geographic Context

The gulf connects to the Gulf of Oman and the Arabian Sea via the Strait of Hormuz, a critical chokepoint for global oil shipments. Major coastal nations include Iran, Iraq, Kuwait, Saudi Arabia, Bahrain, Qatar, the UAE, and Oman.

Economic and Ecological Significance

The Persian Gulf holds roughly half the world's proven petroleum reserves and is a hub for oil and gas production. Its shallow, warm waters support unique marine ecosystems—coral reefs, seagrass beds, and mangroves—though these face pressure from industrialization, desalination, and climate change.
