Are disney princess dolls compatible with toy story characters?

The only verified data we have references the Toy Story franchise as a distinct entity and provides a detailed description of Elsa from Frozen, which is unrelated to toy compatibility. There is no source indicating that Disney Princess dolls share joint dimensions, size standards, or mounting systems with Toy Story figures. Both lines are produced by the same parent company, but product lines are typically designed independently with different scale specifications. Consequently, any compatibility would be anecdotal or based on user experimentation rather than official documentation. If you plan to mix the two, it is advisable to examine the measurements of each doll or seek manufacturer guidance.
