It seems like everything I see uses a different scale! What do things like “1:48,” “quarter inch,” “O,” and “40mm” mean?
For some reason, different terminology is used for different modeling genres (1/48, quarter inch, O, and 40mm are actually all the same size). A scale written as “1:48” or “1/48” is a simple ratio: one of our inches equals 48 of the model’s inches. “Quarter inch” and similar notations usually refer to architectural material: it’s a shorthand way of saying “one-quarter inch on the model equals one foot on the finished product” (in this case, 1/4″ = 1′ is the same as 1/4″ = 12″ which is the same as 1″ = 48″ or 1/48). “O” and other letters (“G” “HO” “N” and “Z” are also common) are Model Railroading scales. Each letter has a unique scale, i.e. “O” equals 1:48 and “HO” equals 1:87. Finally, scales noted as “40mm” refer to figure modeling, where the number expressed represents the average figure’s height in millimeters.
