The exact height of Bhagwan Mahavira is not reliably fixed in commonly accepted Jain tradition, so I should not guess.
Explanation
Jain teachings focus more on Mahavira’s spiritual greatness, vows, and liberation than on precise physical measurements.
Spiritual Understanding
In Jain Dharma, the true greatness of a Tirthankar is in self-realization, compassion, and complete victory over inner passions, not in bodily description.
Takeaway
Bhagwan Mahavira’s spiritual height is far greater than any physical measurement.
