Height estimation for my filly please?

[petite-girle]

My filly is now 16months old and currently 12.2hh. I have no idea about the height of her parents. Can anyone guess from her age and current height how big she might get? I got the poor little girl at 5 months old (she was TINY) and a friend said she'll only make about 12hh fully grown. She's already bigger then that now as a yearling
I'm 5ft2 and weigh 7stone so quite a small adult, hoping she'll grow big enough for me to ride!

Have you done a string test?

1.MOST ACCURATE is to measure elbow to ergot/fetlock with a string. Then "flip" the string, rotating from the elbow and raising the bottom part of the string up, vertical and taut, aligned with the wither. This is the final horse height.

2.Second string test method: measure from the front part of the coronet band on the hoof right where the hoofwall meets hair, and pull a string straight up to the center of the horses knee (where the dip is in the middle of the joint). That measurement will co-incide with the horses final height. So if the measurement is 15 and 3/4 inches, the horse will be 15'3.
