So I came across some figures (54mm, 75mm, 80mm) in a book that look great for the RR but not to sure about what would be a normal hight? Now I DON’T want to start a sizing match like we have had before. I just want a round about MM size figure that is all.
Just divide mm by 25 and that will give you a close number in inches (its mm / 25.4 = inches to be exact). I like figures in the 2.5 to 3 inch range for my railroad using about 1:24 scale. For 1:20.3 - 3 to 3.5 inches is about right.
