how big wil a 8mth old colt be if it is 12,3hh now when fully grown.?

I heard an old method, though I never got to check it. But give it a try:

Measure from the ground to his elbow. When he is full-grown, that should be the same as the measurement from his elbow to his withers. So you should be able to do the math and make a guess about his grown-up size.

Somewhere between 14-15hh I'd say.

My filly was hitting 13.2 at around 9 months and she should make 16hh, so I'm just working out my answer from that!

i understand your very anxiouse to journey him and im confident he would desire to hold you yet hes not waiting yet you will destroy your little colts possibilities of living a protracted and healthy existence and if somthing occurs to flow incorrect are he is going decrease back to the pasture in any discomfort he will undergo in strategies that as his first experiance at being below the saddle and in all probability by no potential rejoice with carrying you lower back artwork on the floor and get him so waiting and tender with you that by using the time you do get on him it wont even issue him and how forward for you and your colts relationship would be a protracted-lasting and rememberable one with years of superb cases iv have been given a 4 month previous filly that iv all started small quantities of educating daily seince she became into born and are relationship is somewhat good she trusts me to do something along with her the different day i walked her and her mom some distance remote from domicile and he or she had this variety of superb time she shall we me p.c.. up her ft supply her a bathtub flow tie her and a important sort of different issues we've all started on her floor artwork and shes catching on so rapid she will already lung flow remote from stress and walk trot canter at a voice comand shes going to be the perfect horse i only know it yet I ought to attend tell shes a minimum of two and a nil.5 years previous even even with the incontrovertible fact that some vets would inform you its ok to journey them at 2 iv heard to many undesirable experiances and dont % to risk it only rejoice with him being a yearling and grasp each and all of the learning that he desires to appreciate undergo in strategies even getting them to p.c.. up there ft is substantial so artwork on the little issues that count number and journey the mare are yet another grownup horse that would desire to % to take you for a journey

My welsh cob was 11hh when he was 11 months, he'll finish around 12.2. So my guess would be 14-14.2hh. It's just an estimate though, it all depends on what you feed him, his health, his growth rate, and his parent's height. Hope I helped :P

do you know how big his parents are? they are normally around their height.

if i had to do a guess i would say around 15+hh

i dunno.
