From the outside, it's harder to tell. The difference in widths between an Airbus 319 and a Embraer Regional Jet is greater than the difference in widths between that A319 and a Boeing 767, but the 319 and the Junglejet are both "narrow bodies", while the 767 is a wide-body with its 2-3-2 configuration. Silhouettes are very deceptive; a DC-8-63 or a 757-300 are just as "long and narrow" as a 777, and except for the 340's winglets, it looks a lot like a 707 or DC-8. 767 or 737? Without any sense of scale, they look the same. Among airliners, anything with a T-tail is a narrow-body. (That is, until Lockheed or Boeing develops an airliner based on their cargo jets, such as the C-141 and the MD-17. :-) :-) :-) ) Other than that, there aren't any good rules about wide-body versus narrow-body apart from memorizing and recognizing distinctions in silhouettes. >thanks Nick
