The same machine fits in your palm at 1/144 and swallows a whole shelf at 1/60. Enter the in-universe full height and shoulder width, add the scale denominator, and the finished height and width come back in inches, together with the shelf width it will take once you allow a display margin.
The math is the plain scale proportion: real dimensions divided by the scale denominator give finished dimensions. The table applies the three scales the maker prints on its product lines, 1/144 and 1/100 and 1/60, to the same machine so the heights sit side by side with the ratio against 1/144. Those ratios are generated from the scale list held in the code. Current as of October 2026.
The tool makes no claim that one product line is better or suited to beginners, because no official standard for build difficulty or articulation exists. Part counts and build time, paint cost and bottle counts, and box heights that include protruding antennas are not covered. Treat the figures as a reference and measure your shelf.
Frequently Asked Questions
No. There is no official standard that puts build difficulty, articulation or color separation on a numeric scale, so this calculator does not steer the choice. It only shows how much the finished height changes when the same machine is built at different scales.
They are the scales the maker prints on the box for each product line. Some kits depart from the printed scale, so entering the figure from the actual box into the scale denominator box is more reliable.
Box heights are measured differently from kit to kit, some counting antennas or backpacks and some not. This calculator only divides the in-universe height you entered by the scale.
