Mine is about the same as yours -- it does vary if she is very tired or if it is dark out when she goes to sleep, in both of those cases she settles faster. Otherwise she will take up to an hour. Sometimes, she is so busy playing in her crib I think I put her down too soon too and wonder if she's going to go to sleep at all -- but typically within 10 minutes of my having the "maybe I should just get her up" thought she's asleep. I find now that she's getting older I can sometimes ask her to lay down, sometimes in a friendly voice, sometimes in a soft but stern voice and she'll do it.
