It partly depends on which suite you are considering.  The G cabin beds are smaller. The Regent Suit is bigger.    That said, for standard F thru A cabins, the bed size is “about” 68 inches wide and 74 long, when set up as a King. I am measuring a bed on Explorer.  The bed frame is actually 2 frames pushed together. The top of the mattress has a zipper to connect both halves together.    For 2 twins, the halves are separated. The bed stands will be placed in between.
