Sorry, but there's no specific answer. A full mattress is 53" X 75" (I think Tartan's chart is in cm, no that can't be right?). You need to make some decisions. How much do you want to hang over the edges? 4"? 14"? What will you do at the pillow end? Will the pillows go on top of the quilt, or do you want a pillow tuck?
So for a quilt with a 5" drop and no pillow tuck it would be 63" X 80"
To cover both mattresses, a 14" drop would be needed, so the quilt would be 81" X 89"
