I've got a king Cole DK pattern for a jumper. It's chest sizes are: 24/26 then 28/30, (no age guide) I measured DS (8 yo) at 27" so decided it would be best to do 28/30 with slight growing room. I'm half way through to front and thought it looks quite big so I measured the width and its 16.5", I looked at the pattern and it says chest size 28/30, actual size 36" (the 24/26, actual size 32")
Why on earth is the an 8" difference? Even loosely fitted shouldn't be that much surely?
