The word bonsai is translated wrong. Bon means container( pot, tray, stone or slab) aslong as ther ia an relationship between the two and sai means plant.

Then the first part of you primary features you refer to small size with specific dimensions as a reference. It should rather just be a smaller version as the one found in nature. Bonsai range from 5cm to a 1,2 m and morerange. There are bigger one out there the imperial bonsai.

These are just my inputs but as most of these thingss are translated from other languages alot gets lost in translation.
