There are so many tiny dolls out there and I am being asked all the time which dolls my patterns fit. It can be difficult to know without having the doll in front of me, but I have spent some time gathering together measurements and am fairly confident now about sizing. My own doll is a Doll Family JoJo (how I would love to have a Lati Yellow) which is a fairly average tiny doll size. As knitted garments are so stretchy anyway they adapt fairly well to most tiny doll sizes. All my basic patterns will fit 5 to 6" (13 to 15 cm) dolls house dolls including Heidi Ott, also Pippa, Dawn and Kelly. Those patterns which are either specially designed for larger heads, or have a front opening such as a cardigan will fit 5 to 7" bjds (13 to 18 cm) such as American Girl, Rosen Lied Monday child, Lati Yellow, Pukifee, Bobobie Tiny, Ellery Kish and JoJo. They fit but look oversized on smaller 4 to 5" (10 to 13 cm) PukiPuki, Lati White, Yoshi, and Hujoo baby, although I have adapted patterns and knitted specially for these sizes. I also have some patterns for dolls house child dolls such as the Heidi Ott children, which are 4" (10cm) tall.
Hope that helps!
