I was told from one person that jumbo/extra jumbo/etc. is just the size of the fretwire, but then I was told that it determines the width of the frets themselves... Which is it?

6150 is considered Jumbo. 6130 is often called Medium Jumbo. 6230 is very small like vintage Strats. The drawing's not to scale and only shows the general shape/proportions.
