The other putty based models, if using standard bases in the pictures, are pretty much non-willy and a lot more compact. These 3Ds are unknown, no reference provided (or measurement, you know, computers, numbers... should be easy to pick a size and stick to it).

~30 to top of helmet with an obvious 25mm base.

~29 to top of horns, guessing a 25mm.

~33 to top of head, if using a 30mm base.
The hands go a bit out of the base, but that's normal for the poses.
