Ok let the jokes begin LOL but is there a way to tell all these different scales converted to American inches for instance a 1/12 scale bust would be how many inches tall ? Thanks rob

There is no set height for a 1/12 bust (or any bust for that matter).
It depends very much on the height of the figure the bust represents.
I posted a table of scale heights for a number of actual heights:-
https://www.planetfigure.com/threads/scale-sizes-in-terms-of-inches.274828/#post-1098149
The scale heights are given in both mm. and inches.
You then need to determine the cut-off point for your bust in real size and it's actual size relative to the actual height.
A simple fraction will give you the height of the model bust.
Alternatively, you can simply use the scale height of the figure to define the bust size (for example: a 1/9 scale bust is often quoted as 200mm).

You realise that an inch is the same in every country. No such thing as an American inch.

Effectively if you know the size of the head you can scale that up. 1 inch on the head = 12 inches (or 1 foot).

Many bust sculptors aren't exactly to scale anyway so I wouldn't stress about it.

Thank you both for the replies and info I appreciate it . Rob

Than’ you for the link Andrew it’s just what I was looking for

Not true ours are bigger . But ya there seems to be no consistency in scale.

Well, and don't forget the Texas inch, which is even bigger, 'cause everything is bigger in Texas

Here in PA, we have the Pennsylvania Dutch inch, which starts out as an inch, but gets bigger every time you tell the story.

Prost!

Inch or ego?

First what is the scale of the hand
It's a bit like telling convert in iPad size
