Knee to coronet measurement/height prediction...

[rideagoldenpony]

I measured my yearling Welsh colt this evening to do the knee to coronet height prediction. He’s verrrry leggy, and is almost 17 months old. The measurement says 13.2 hands, right on the nose.

I was sort of expecting him to finish smaller, so this would be an unexpected bonus, but does kind of jive with how long his legs are. I also did the elbow to ergot/reverse thing with the tape, but I was alone, so it was hard to tell how much more it was going to be, because he just wanted to know what I was doing! LOL It looked on that like 4ish more inches. He measured at 12.1 1/2 hands a couple of months ago.

Any experience with how accurate/not accurate this measurement is? I’ve not tried it before.

I’ve never had alot of faith in it, but when I measure my fully grown horses, its spot on. Have you tried it with your grown ups?

the ergot one is more accurate. The first one will at least tell you since he is leggy that he will probably be “not over 13.2”. On a leggy horse the coronet band one may be skewed on the too tall end. If you can’t flip the tape accurately with a squirmy horse do it this way: add the ground to pastern height (only count it once) and add it to the pastern to ergot height (which you double). Comes out the same but you are not left holding the tape in the air and trying to measure it!

A general rule for horses is 2 hands added to the yearling height, but I’d subtract 1-2" since he’s 16 months, maybe.

I have had both string tests be accurate on the adults I’ve used it on, and they were accurate for my 1 foal whom I still have.

But yeah, as camohn said, for a horse who has longer or shorter legs than the average horse, it will be skewed.

that works for horses but this is a pony…so adding 2 hands will be too much. I don’t know what the pony equivilant is.

Well, 2h added to 12.1 is 14.1, and subtracting a couple of inches comes down to the general range of what the string test is showing

Maybe we need another thread on what the general rule is for ponies

I tried both methods on my 3 yr old. The one from the middle of the knee to the cornet said he would be 16.1, the one where you measure from the ergot to elbow then flip says he will be almost 17 hh… I would like it to be the later, but I won’t be holding my breath.

Does anyone have any diagrams of these ways of measuring?
