Does castration cause the penis to shrink?

If so by how much?

No, the castration does not cause the penis to shrink. It is the lack of testrosome causes the penis to shrink..

Or perhaps the lack of use causes the penis to shrink.

There is the thought that the lack of spontaneous and nocturnal erections cause the penis to shrink. I have lost about 1 1/2 inches through the years without TRT.
