SCALE CROSS REFERENCE

The table below is designed to assist you in choosing the correct dimensions when scratch building or even verifying the accuracy of kit models. For example, if you want to add an antenna wire to your 1:72 scale aircraft and you know that the real life wire is 5 mm in diameter then you can use this table to cross check that the diameter of the wire you need on the model is 0.07 mm.
