Where can I find the iPhone5C/S dock dimensions?

I want to build a wood inwall niche that will accomdate the new dock and phone but cannot find any dimensions for the docks themselves. I am trying to get height, width and depth of the docks so i can be sure to hold them in place. I do not have the dock or phone (still have the 4s with 30 pin dock), but want to make sure the niche I build will work with the new ones when I get them.
