I have never been able to get close enough to measure him with a tape measure. But judging from the distance between my fence post which are 10 feet apart I would make an educated guess of 100 to 110 inches tip to tip. A Longhorn steers' horns grow for their entire life so he may get to 120 inches one of these days, time will tell. He is definitely on the top of the pecking order in my pasture, my two horses give him the complete right of way!
