I asked this question once before, but I think it was misinterpreted. I know that 1/144 kits are more-or-less 5 inches tall, 1/100's about 7 inches and 1/60's 12 inches, but how are these estimates made? What I want to do is use a model's scale to determine the size of the finished product in inches, before I open the box.
1. go to MAHQ main mecha page
2. search entry for mecha you're interested in kit form
3. read up specs including fictional height in meters
4. then do the math depending on 1/60, 1/100, 1/144 scale as mentioned by everyone else above.
Remember these mechs all have ficitional height already determined.
