Frequently asked questions

How big is a 1:72 model?

Divide the real length by 72. A 15 m fighter jet becomes about 20.8 cm, and a 1.8 m person becomes 2.5 cm tall.

Is 1:72 bigger or smaller than 1:48?

1:72 is smaller. A 1:48 model is 1.5× larger than the same subject at 1:72, because 72 ÷ 48 = 1.5.
