How deep is each part of the Red Sea?
The bar splits the Red Sea's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 39.5%
- 200 to 1,000 m: 45%
- 1,000 to 4,000 m: 15.6%
- 4,000 to 6,000 m: 0%
- below 6,000 m: 0%

The Red Sea if sea level dropped
The slider on the map lowers the sea in steps. This table shows how much of the Red Sea's water would be land at each step.

|---|---|---|
| 10 m | 34,569 km² | 7.8% |
| 20 m | 73,040 km² | 16.5% |
| 50 m | 120,074 km² | 27.1% |
| 80 m | 148,816 km² | 33.6% |
| 120 m | 161,859 km² | 36.5% |
| 200 m | 174,955 km² | 39.5% |
| 500 m | 230,561 km² | 52% |
| 1,000 m | 374,129 km² | 84.4% |
| 2,000 m | 439,846 km² | 99.3% |
| 3,000 m | 443,146 km² | 100% |
| 4,000 m | 443,146 km² | 100% |

Frequently asked questions
How deep is the Red Sea?
On average about 504 m in the GEBCO grid (the middle value is 462 m). The deepest cell inside its outline is 2,844 m, at 19.61° N, 38.73° E.
How big is the Red Sea?
About 443,146 km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Red Sea would be land if sea level dropped?
With the sea 10 m lower, about 34,569 km² (7.8%) of its water would be land. At 6,000 m lower, 100% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
