Props Advice for Proportions - 3D-Printed Monster Taxidermy for 72-CM Doll

Hello, All!

I am planning to 3D print a monster skull at some point in the near future to use as a trophy room prop for an SD-size doll (with a head size of 22.5CM - proportions roughly equivalent to a ResinDoll Yi or Heng). For the best results, what size should I aim to print the skull? The size ratio I was envisioning was "normal human" (my doll) to "large primate or Sasquatch" (the monster skull).

Any guidance with this is appreciated!
