These socks are made specially to fit Bitty Baby and American Girl dolls. An adorable addition to make an adorable outfit!Also will fit babies up to about 7 pounds. The doll's foot is 2-1/2 inches long x 1-1/4 wide. I had a terrible time finding socks and shoes small enough when our three girls were born. It turned out that they all inherited Mom and Dad's narrow feet. (Piper measured 7A when she was wearing a woman's size 7! That is 3 A's narrower than the narrowest shoes sold in America! I had a shoe repair man who redid every pair of sandals she ever got.) At least this will help you with the socks.
