Measuring the length of raglan sleeves

I´m working on this cardi
and am wondering if I¨m supposed to measure the length of the sleeves from the underarm or the top? I have both arms done and measured from different spots, so one the incorrect one will have to be frogged and re-done.



Looking at the schematic and reading the instructions for the sleeves, I would measure from underarm to cuff for the 6".

Oops, schematic… forgot about that… :wink: thanks a bunch - off to make the shorter sleeve longer!!!
