At what height does a fall classify as an MTV for children?

When determining the classification of a fall as a mechanism of injury, particularly for children, the concept of "twice their height" reflects an important understanding of risk relative to the child's size and growth. This classification considers the potential for significant injury based on how far a child falls compared to their own height.

Since children are typically much shorter than adults, the threshold for what constitutes a major trauma from a fall is relatively low compared to adult standards. Falling from a distance that is twice the child's height is significant enough to potentially result in serious injuries, such as traumatic brain injuries or fractures, due to the height and velocity of the impact.

In contrast, the other height options do not adequately consider the height relative to the child's size. For example, a fall from 5 feet, 10 feet, or 15 feet does not necessarily correlate well with the individual height of every child. A child who is 3 feet tall, for instance, would not experience the same risk from a fall of 10 feet as a child who is 6 feet tall. Therefore, the "twice their height" guideline is more universally applicable and reflects a higher standard for protective measures when evaluating falls involving children.
