Depends on the goat, I raise Boers and they have a wide range in height depending on the breeding, Although Dairy breeds are usually taller, Where as meat breeds are heavier I have a couple of does that go 250 to 300 pounds the average is 150 and a full blood buck at almost 400. The tallest Goat in my herd is my Nubian doe. Boers all have dairy in their background so it's possible to get a tall one. I would still say that Nubians are usually taller goats.
