Question Length of an indirect variable

The construct ${#parameter} returns the number of characters in the parameter and ${!parameter} specifies an indirect variable. My question is: How do I combine these two. What I want is ${#!parameter} but this gives an error.

Of course I can use:
dummy=${!parameter}
${#dummy}
but that's a bit ugly.
