There is no height difference. A softball mound is not raised like a baseball mound.
In MLB, the pitching rubber is at a height of 10 inches.
The height of the mound and the size of the pitching rubber could vary from one level of baseball to the next, but within each level, they will be the same.
The top of the rubber is to be no higher than ten inches (25.4 cm) above home plate. From 1903 through 1968, this height limit was set at 15 inches, but was often slightly higher, sometimes as high as 20 inches (50.8 cm), especially for teams that emphasized pitching. The lowering of the mound in 1969 was intended to "increase the batting" once again, as pitching had become increasingly dominant, reaching its peak the prior year; 1968 is known among baseball historians as "The Year of the Pitcher". This restrictive rule apparently did its job, contributing to the hitting surge of modern baseball.
The diameter of an MLB pitcher's mound is 18 feet.
