Formula for determining heigth?

[clpclop]

I'm always reading or hearing someone say..."she should mature to 29 inches". How does one determine what a colt or filly will mature to?

I know I've heard of a formula or two...anyone know of any?

I'm answering my own question. Apparently I've asked this before and did recieve some feedback. The cannon bone formula was questioned. The easier method is: Birth Height minus the Height at 3 Months plus the Height at 3 Months i.e. Birth Height (19") minus 3 Month Height (24") = (-5") Plus (24") = 29"

My filly born on 3/30 is now smaller than my colt born on 4/25. I have a hunch she is going to be a nice small little girl!
