The engines of the Boeing 757 are substantially smaller, however.
The 757 can be fitted with either Pratt & Whitney PW2000 series or Rolls Royce RB211 turbofans. The maximum
the RB211 is only 6 ft 2.5 in (1.9 m) while that of the PW2000 series is 7 ft 0.5 in (2.15 m). Meanwhile, the 757
fuselage is 12 ft 6 in (3.75 m) in width. In other words, the engine width is only a little over half that of the
fuselage, about 57% as wide to be precise. This comparison can be better observed by studying the above three-view
diagram of the 757.
