Well, I've been parked next to the AirFrance A380, Qantas, and Singapore, Emirates, and all of them are HUGE.  The Engines are ridiculously giant, and loud to move the oversize aircraft.

Smaller however, than the General Electric GE90 on the Boeing 777, they're between the size of a GE90 and a GEnx, they put aout around 85,000lbf. For some reason, only inboard engines have reverse thrust.
