They're usually considered to be "Eleven-inch fashion dolls". A 2" scale
(2 inches = 1 foot, or 1:6) is just about right. There are also some
ready-made items in that size.

In general, what scale are standard typical Barbie dolls? I'm going to
build some doll furniture for my grandaughter and have no idea what
scale they might be considered as. First project will be a rocker type
bed, then whatever she wants from there.
