I used the search bar before commenting, I have that exact same question. I have Blythes, but am considering to buy one or two small BJDS that would fit a 1/12 scale dollhouse, simply because I really really want to decorate a dollhouse, and there are many amazing modern dollhouses on a 1:12 scale. But there is no sense of a dollhouse without dolls to live in it, right? I looked at Lati yellows and YO-SDs on some pictures and decided they look adorable and I would consider one of them if it fits a 1:12 scale dollhouse. What are the measurements in cm of those dolls? Thank you in advance for your time!
YoSDs are about as tall as a Barbie doll, if not taller and as they are quite a bit bulkier than Barbies or Blythes, they look too big for even the 1/6 scale houses. The standard 1:12 scale dollhouses are even a bit too small for Lati Yellows, but are likely good for Lati White SPs or Pukipukis (which are about the same size as the Lati White SPs). I have a vintage Lundby dollhouse, and the pukipukis were the right scale. You might want to look at Pukipukis, Lati Whites and the Nabiyette when they are reissued. EDIT: Noticed that was your first post -- so, WELCOME!
Sleeping Elf"s dolls were designed to be able to fit in a 1:12 scale dollhouse. The newer big version of some of the dolls would be too big though.
