How deep is each part of the Philippine Sea?
The bar splits the Philippine Sea's water by depth. Each colour is a depth band, and the shares add up to 100%.
- 0 to 200 m: 1.3%
- 200 to 1,000 m: 2%
- 1,000 to 4,000 m: 24.6%
- 4,000 to 6,000 m: 66.9%
- below 6,000 m: 5.3%

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

|---|---|---|
| 10 m | 4,351 km² | under 0.1% |
| 20 m | 9,418 km² | 0.2% |
| 50 m | 29,204 km² | 0.5% |
| 80 m | 44,675 km² | 0.8% |
| 120 m | 59,204 km² | 1.1% |
| 200 m | 74,266 km² | 1.3% |
| 500 m | 110,902 km² | 2% |
| 1,000 m | 183,190 km² | 3.3% |
| 2,000 m | 423,417 km² | 7.6% |
| 3,000 m | 821,967 km² | 14.8% |
| 4,000 m | 1.6 million km² | 27.9% |

Frequently asked questions
How deep is the Philippine Sea?
On average about 4,472 m in the GEBCO grid (the middle value is 4,779 m). The deepest cell inside its outline is 10,931 m, at 11.34° N, 142.21° E.
How big is the Philippine Sea?
About 5.6 million km² of water inside its Natural Earth outline, counted from the grid cells that are below sea level.
How much of the Philippine Sea would be land if sea level dropped?
With the sea 120 m lower, about 59,204 km² (1.1%) of its water would be land. At 6,000 m lower, 94.7% would be. This is a simple bathtub model that lowers the sea evenly everywhere.
