The problem with BG3 body sizes is down to poor implementation by Larian. The body size in most games is controlled by sliders not restricted to three different fixed sizes. There are mods for Skyrim which provide a better CC than Larian. Come to think of it the same can be said for CK3 mods.
Larian had six years.
