Size Matters?
Well... having been in a number of corporate and airliner cockpits, I can tell you that from my personal perspective... The Citation cockpit, although cramped, is fairly comfortable... the Falcons are fairly comfortable as well, with a little more elbow room. The Sabreliner has a pretty roomy cockpit, and so does the Challenger. The Gulfstream cockpits I have been in were a little cramped, and the LearJet is nearly impossible to get yourself into. The Beech and Diamond Jets are in-betweens and the Westwind cockpit is fairly cramped, but it's got some room once you are in and situated. As far as some of the bigger stuff goes, the CRJ looks a little more roomy but is fairly cramped with two big guys in there and the cockpit door is RIGHT behind your position, same with the jetstream and b1900 cockpits. The DC9 and MD80s are terribly small. A320/A319 have the same size cockpit, and it's fairly roomy with a lot of space, it's a great ergonomical design and is pilot friendly. Same for the 737-700. The 737-200 is a little small, but gives you some room once you are sat down and ready to go. All of the 747 I have been in were pretty tight fits unless you were riding in the jumpseat, and the 757 and 767 have a pretty good amount of room. Especially the 757. But the best cockpit design in the world for comfort and space was the McDonnell Douglas DC10. It offered plenty of room with a lot of space between elbows. The flight deck visibility was out of this world, and although it had 3 crew members on the flight deck, still had plenty of leg room for 2 cockpit jumpseats. The best cockpit jumpseat of any airliner, ever was the DC10 cockpit jumpseat just aft and to the left of the Captain's side. It had plenty of room and offered an outstanding view.
