Can anyone tell me where drawings can be found that accurately illustrate the size difference between the 767, 787 and 777. I get the impression the 787 is mid way between the 767 and 777, but on looking at photos of the 787, I'm impressed with how large the airplane seems to be. Closer in size to the 777?

All three are widebodies. From narrowest to widest, it's the 767, 787 & then 777. The 767 is the narrowest widebody of any commercial jetliner in service, while the A380 is the widest widebody. I have specs & numbers somewhere...will look for them and get back with you later.
Regards.

I think he's looking for an image that puts the outlines of all three aircraft on top of each other as seen from various angles to clearly show which aircraft is larger.

I've seen a similar image comparing the 747, A380, and AN-124, but would really like to see one comparing these three birds, too.

The following Boeing table is also a handy comparison of basic dimensions and weights of most Boeing (and former Douglas and McDonnell Douglas models). It only shows the 787-8 (the one recently rolled out), not the -3 or -9.

As for floor area, if that's what you are after, the 788 is very close to the 764, so that's why in 9Y seating, a 2-class 788 will hold about the same pax as a 2-class 764. For CO, if they go with 9Y, that's about 235-255 seats depending on how many J they put in. If they go 8Y (which is now re-rumored that they will) it will be about 210-220 seats.

The 789 is 20 feet longer, which would give 1 more row of J plus 2 more in the middle, 2 more bathrooms, and 4 more rows of Y, 40 seats, 250-260 seats, which is still smaller than the 777. But in 9Y, a 789 is basically the same capacity as a 772.

That's exactly what I'm looking for. You explained it better than I did! Much appreciated.  Smile

You can get scaled plan-view drawings of all Boeing aircraft from the airport planning documents, as posed in Reply 2.

A little bit of playing with an image editor will give you something like this:


This is a 777-300ER, 787-8, and 767-300.

I tried doing it with more aircraft on the same page but it started getting too cluttered way to quickly.

You can clearly see, just from these three models, that the 767-300 and 787-8 fuselages are very close, but the wing and engines are far larger.
