Ratio of Barbie Doll to Human Adult...?

Question

Hello, This may sound like a strange question, but I'm TOTALLY serious.

Does anyone know what the ratio for a barbie-type doll (11 and 1/2 inches tall) would be to an adult human (preferably a 5'5" woman)? I'm terrible at math!

Also, ignoring the crazy waist and bust size, if I wanted to take a crochet barbie-type doll pattern and convert it to an adult woman (preferably 5'5"), what would I multiply everything by? (I guess that would depend on the ratio :)

Like I said, I know it sounds strange, but this is VERY important, if anyone could give me their two cents!
Thanks so much!

Answer 1

11 and 1/2 inches = 11.5 inch
5'5" = 65 inch

So the ratio = 65/11.5
= 5.65

So multiply the size of the barbie doll by 5.65

for example if you measure 3 inches in barbie doll it should correspond to about 3*5.65 = 16.95inch nearly 17 inch in human counterpart
