A Super King size bed is typically a UK or Ireland King size bed.  The UK Super King is 72” by 78”, whereas the traditional UK King is 60”x 78”.

The standard US King size bed dimensions are 76” x 80” which is larger than the UK King in both length and width.  That’s why Super King bed size in the US often refers to other oversized king beds.   These beds include the Alaskan King, Texas King and Wyoming King.  Though technically, the Super King bed terminology identifies the UK size or other sizes that originate from other countries.
