Alright... for some this is going to be hard to believe! The 707, 727, 737, and 757 all have the same fuselage circumference. Meaning the passenger cabin is the same width. But, if you really start thinking about you'll see they all have 3-3 seating, so I guess it makes a little sence. But then you thin about it this way... The BBJ has the same fuselage circumference as the 757. I mean... it's just wierd! Any comments?

Back when the 707 first entered production, Boeing came up with varied lengths for the fuselage to suit various customers. Later, the 727 and 737 series had the same fuselage cross section and cockpits as the 707. The similarities were noted, and a joke was made that Boeing had a machine that produced one long, continuous fuselage, and that varied lengths were cut off and made into different aircraft types as needed.
I don't QUITE think this trend has continued with the 757 and 737NG; though they are similar in fuselage circumference, there are some differences. Can anyone confirm this?

This is besides the point but, did you know that the 727 fuselage and the 757 fuselage are the same length? I have a little booklet called the "PlaneFacts" printed by United, and the 727, and the 757 both are 153 feet long. WOW! The 757 always seemed longer.

yes... it did continue with the 757 and 737NG. The Next Generation 737's are just longer! There are slight differences... but you can't tell. You gotta get really technical (sp?) before you actually see it!

727-100s are shorter. But the 367-80 (I believe that is the first 707) actually has a narrower fuselage than later ones. Original 707s were designed for 5-across seating.
And although your study of 757s vs 727s is good, and probably accurate, the flight decks and nose are completely different. Further, the aft end of a 727-200 has a bulkhead somewhere. Aft of that is an engine and some ducting. This is probably included in the comparrison.
All 727s I've ridden in are short inside compared to all 757s I've flown in. If one were to count seats a difference of interior length could be found easily.

Greeneyes, yes, the 367-80 (or 707 prototype) had a narrower fuselage. It shares this narrower fuselage with many hundred C-135 (mostly KC-135) delivered to the US Air Force some 40 years ago.

The cabin cross sections of Boeing narrowbodies are actually not identical.
Boeing only kept the upper lobe of the fuselage (from floor up) of the 707,727,737 and 757 the same. Only the 737 and 757 fuselage is really the same .
If you look closely, the 707 floor level is around the middle of the fuselage while the 737 floor level is lower.
from the front the 707 is more oval than the 737.
but I don't know whether the 727 fuselage has a larger height than the 737 or not.
there are 3 types of 707 fuselage. First the 132" 367-80, then the 144"KC135, and the production standard 148".
