The query "how tall is" is incomplete and ambiguous as it lacks the subject or object whose height is being asked. If the inquiry is about human height in general:
- Human height is the distance from the bottom of the feet to the top of the head in a standing person. It is measured in centimeters or feet and inches depending on the measurement system.
- The global average height for adult men born around 1996 is approximately 171 cm (5 feet 7.5 inches). For adult women born around the same time, the global average height is about 159 cm (5 feet 3 inches).
- Average heights vary significantly by country and region due to genetic and environmental factors such as nutrition and health.
- For example, in Germany, an average man is roughly 178-181 cm tall (about 5 feet 10 inches to 6 feet), and an average woman is around 166-167 cm tall (about 5 feet 5.5 inches).
If the question pertains to a specific person's height, a famous landmark, or an object, please specify the subject for a precise answer.
