What is the difference between depth and height?
Both measure distance in the up-and-down direction, but from opposite reference points. Height measures how far something rises upward, like a tower or a person. Depth measures how far something goes downward, like a pool or a well. The same pool has a height above the ground and a depth below the surface.
Can depth be used figuratively?

Saying someone has depth means they are thoughtful and complex rather than shallow. The figurative sense borrows the idea of going far below the surface.
How is depth measured?
Depth is measured from the top or surface straight down to the bottom. For water you measure from the surface to the floor; for a hole, from ground level to its lowest point. It uses the same units as any length — metres, feet, or centimetres — just taken in the downward direction.
