If giving out the length hurts anything, there's enough going wrong that you should probably assume it's already compromised.
Unless there's something fundamentally wrong with the password, a public length of n is almost as secure as a secret length of n, and significantly more secure than a secret length of n-1
Never get into the specifics of a password, but explaining the basic structure should be a tiny impact and well within your margin of safety, or you didn't make a good enough password to start with.
