In Jain scriptures, no Chakravarti is described with a height of 15 dhanush.

Height of 15 dhanush is given for Bhagwan Naminath, who is a Tirthankar, not a Chakravarti.

Among the 12 Chakravartis of the present time-cycle, the smallest height mentioned is 20 dhanush (Harishen Chakravarti); others are taller.
