hard to tell then! maybe cobby one 13.3 ish maybe 14.1hh. i have no idea about the arab x TB...? 15.3... ? could be quite big!?! These are complete guestimates though!
Are they yours? Try measuring from the middle of the knee on the side of a front leg down to the coronet band - the length in inches is supposed to be the final height. e.g 15 1/4 inches = 15:1.
This worked on a couple of youngsters I know but it's probably not foolproof.
If they don't have access to the right nutrients...then it can temporarily or permanently reduce their growth...
Assuming you are feeding it properly now
then you may find it grows a little more so could make 14h or thereabouts.
