>>13559892A quick search on Google says that the height of a boy can be calculated as [(Mother's + 13cm) + Father's]/2
That adds up to 172.5 cm in your case.
The error rate is +-5 cm, so your son would be 167.5 cm tall in the worst case scenario and 177.5 cm in the best case scenario. Anything beyond that range would mean there is a medical problem.
In the case of a daughter the expected height is in the range 154.5 cm to 164.5 cm.
