Answer

In the Aupapatika Sutra, Bhagavan Mahavira’s height is described as seven cubits/hastas. Using the traditional conversion of 4 hastas = 1 dhanusha, that comes to about 1.75 dhanushas. ( jainqq.org)

Takeaway

So, if you are asking in dhanushas, the traditional figure is approximately 1¾ dhanushas. ( jainqq.org)
