Any ideas on height?

[marinitagsd]

Hi everyone, I have a 2yrs 6 months filly who standing approx 13.2hds now. Her sire is a 15.2 WB/Cob and her Mum a 14.3 Appaloosa/quarter horse. Looking at her, I would have thought her adult height would be about 14.1, her breeding suggests different. What do you lot think?
Thanks

Is she a first foal?

Try the string test!
Measure with string from the point of the elbow to the centre back of the fetlock, then reverse the string from the elbow to the withers, the difference is how much she still has to grow, not exact but pretty close.
