Getting Back to The Original Question
Getting back to the original question at the heart of this whole thread. The original author had already stated a general understanding as to the comparitive sizes of capitol ships and was asking about the comparitive sizes of fighter craft. From various Canon and non Canon stuff here are some ideas of dimensions for fighter craft as listed by their Canon sources:
Tie Fighter - 6 meters long
Tie Interceptor - 6.2 meters long
X-wing Fighter - 7 meters long
BSG Viper - 8.8 meters long
B5 StarFury - 9.6 meters long
Macross VF-1S - 14.2 meters long
Star Trek Delta Flyer - 30 meters long
Modern F-15E - 19.6 meters long
WC Ferret - 10.2 meters long
WC Hornet - 20 meters long
WC Raptor - 36 meters long
WC BroadSword - 36 meters long
WC Arrow - 20 meters long
WC Excalibur - 26 meters long
WC Longbow - 38 meters long
WC Thunderbolt - 36 meters long
The problem is that a number of these just don't fit with what we see in the games and other things. The Wing Commander craft dimensions given in the books are simply TOO big compared to what we see in the games.
I actually, out of boredom, remeasured everything to try to get some better numbers. I used the images of Blair climbing into cockpits, sitting in cockpits, etc (and similar for pilots in other shows) and, using an average height of 5 foot 10 inches measured out some sizes which fit to what we observe against side view shots of the fighters to scale, counted by pixel number. Doing so I found that the Tie fighters were close to accurate, as was the Delta Flyer and the VF-1S.
Re-measured sizes by my estimation are closer to:
Xwing Fighter - 8 meters
Broadsword - 38.1 meters
Longbow - 28 meters
Raptor - 34 meters
Thunderbolt - 24 meters
Saber - 23.6 meters
Excalibur - 23 meters
Rapier I - 19.5 meters
Hornet - 19.5 meters
Hellcat - 19 meters
Rapier II - 19 meters
Scimitar - 17.8 meters
Ferret - 10 meters
Either way it is pretty clear that the Star Wars craft are by far the smallest fighters in the lineup. Quite an achievement to pack so much power into such compact units, with TIEs being just over half the length of even a small ferret
