The height of a stump above the ground can depend on the context:

• For tree stumps, stump height is typically measured 30 centimeters (about 12 inches) above ground level. If the stump is shorter than 30 cm, the height is taken as the highest point of the stump above ground. The measurement excludes loose leaf litter and is taken from the highest soil surface level, adjusted for ground slope or unevenness.

• For cricket stumps (the three vertical posts in the sport), the official height above the playing surface is 28 inches (71.1 centimeters).

If the question refers to tree stumps, the usual standard is 30 cm above ground for measuring stump height. If it refers to cricket, the standard height above ground is 28 inches. Please clarify if a specific type of stump is meant for a precise answer.
