DOLL AND DOLLHOUSE

gets into the subject of scaling
in the following Youtube:
Joanne has a Youtube that
However, neither the above mentions 1:3 scale, which I call Girl Doll scale. That category includes such dolls as American Girl and My Twinn. I tend to include any doll that is 16"-20" in that range.
There's also another factor when considering scale. That is the thickness of the doll, i.e., is she a 12" chubby little girl or a 12" adult woman. A cookie should look bigger in a little girl's hand than in an adult's hand. Yet a Barbie has tiny hands compared to her height. Sometimes you just have to use your mind's-eye to determine what will work for your situation.
By the way, I prefer to use the ratio symbol when expressing scale. For example. 1:3 instead of 1/3. The following might be a good visual for you. I don't know the author in order to give credit. Though the doll 2nd from the left is technically 1:12 scale, she would tend to look out-of-scale in a standard dollhouse.
Here's my rule of thumb:
Girl Doll Scale
is Half-inch Dollhouse Scale
is Quarter-inch Dollhouse Scale
|What Scale Will Work Best for You?|
The following table might help you determine if the larger 1:6 scaled books will work better for you, or perhaps you will have assurance that the smaller 1:12 version will work best.
