Just How Large is a Standard Tree Anyway?

When reading the descriptions of dwarf, semi-dwarf, dwarfing rootstocks, you come across statements like this, “produces a tree 50-60% of a standard.” Nice! Do you know how large a standard tree is? Most of us do not know. So, 50-60% of what? The following information will partially answer the question. Practically answer because different seeds are used to produce the standard tree, variety differences, soil fertility, and climate play a role in determining tree height. This is not perfect but at least you will know (plus or minus 10%) what the height will be.
