The difference between high tide and low tide is referred to as "tidal range". Tidal range is the vertical distance between the highest water level during high tide and the lowest water level during low tide.

Understanding tidal range is important for activities such as boating, fishing, and beachcombing, as well as for managing coastal ecosystems and infrastructure.
