Pacific Ocean Width: ~16,000 km at Widest

Pacific Ocean Dimensions

The Pacific Ocean spans approximately 16,000 km (10,000 miles) at its widest point—measured along the Equator from the coast of Ecuador/Colombia to Indonesia/Malaysia.

Other Key Dimensions

• North–South: ~15,500 km (Bering Strait to Antarctic coast).
• Surface area: 165.2M km² (46% of global ocean area).
• Average depth: 4,280 m.
• Max depth: 10,924 m (Mariana Trench, Challenger Deep).
• Volume: ~714M km³ (over half Earth's ocean water).

Perspective

At its widest, the Pacific is wider than the Moon's diameter (3,474 km) × 4.5. It covers more area than all landmasses combined.
