120mm is the height of the figure, which is about five inches tall.
And that is why 3D scanning is so popular with creating figures today. Some sculptors set up multiple digital cameras to scan a real person dressed up in period attire and gear to get accurate scaling and sculpting information. This also means that the sculptor needs to know how to use 3D CAD imaging software to correct scanning and proportion errors. This also explains why resin figures are so expensive…the time, effort, work, and researching involved to get accurate measurements and gear…and actually, the best figures are made in Asia, Europe, and (before the Ukraine War) Russia.
Thus, with recasts, the recaster does not do the 3D image scanning of the original sculptor and the original sculptor doesn’t get any payment for all the digital sculpting work performed.
Now with 3D scanning and freeware, some sculptors can pull 3D scanned images off the Internet (free or by purchase) and “kitbash” 3D scans to create a 3D figure, but again, the digital scultptor needs to really know how to use 3D sculpting software to make everything mesh properly.
