If you are a model-maker, you can search for AMT model kits, like this one:

 their index of Star Wars Model Kits is weak, but they have a couple here:

 I built many of their models for Star Wars and they're brilliant. Great detail and lots of pieces. The Millenium Falcon had over 150 pieces---painting and assembly took me over a month. It's 18 inches long. It's the best model-kit I ever owned. 
 The X-Wing, Vader's TIE, Sandard TIE, and Y-Wing were made to scale with each other. (about 7-10 inches long) 
 The scales of the other AMT models differed, but if I remember, they also made: 
 The Tideriun shuttle, 
 The speeder bike (with pilot), 
 C-3PO, 
 R2D2, 
 The ATAT, 
 The ATST, 
 The Star Destroyer, 
 ...and probably more. 
 They had a Snap-Tite series that included:
 A-Wing
 B-Wing
 TIE Interceptor
 all of these were about 4-6 inches long (to scale with their Millenium Falcon Model Kit).
