The Strait of Hormuz is about 90–104 miles (roughly 150–190 km) long and between about 21–24 miles (35–40 km) wide at its narrowest, widening to around 60 miles (about 95–100 km) at its broadest.

Quick Scoop: Size in Plain Terms

  • Length:
    • Around 90–104 miles long (about 150–190 km), running between the Persian Gulf and the Gulf of Oman.
  • Width:
    • Narrowest point: about 21–24 miles (roughly 35–40 km) across.
* Widest sections: up to about 60 miles (around 95–100 km) across.
  • Depth (for a sense of scale):
    • Deep areas reach a bit over 650 feet (around 200 meters).

Why this feels “small but huge”

On a world map, it looks like a slim pinch of water, but that narrow band—only about 21 miles across at its skinniest—carries a massive share of global oil and gas traffic, which is why it’s constantly in the news and policy debates.

In today’s headlines and forum debates, when people talk about “tensions in the Strait of Hormuz,” they’re talking about this relatively small stretch of water whose size makes it a natural chokepoint for global energy flows.
