I have Brother ULT 2001, 2002, 2003, and Babylock Ellageo 2001... They all have largest hoop size 10x6 (that is design size..the hoops are actually listed 10.25 X 6.25). I have done emb'd quilt borders , some quilting, and have not yet needed a design larger. The only hoop I desire is a 6x6, and because my machines are older, there is not one to fit.
