The only way I could get a picture of his whole self was to put him in a container where he had no place to hide, and hope he would hold still for a few seconds.
I'd say he was about 1¾ inches long and very fast moving. I have not had good luck with little centipedes. They seem to die very quickly when removed from their dark, damp hiding place. So when I finished taking pictures of this one, I released him under a partly-rotten log in my yard.
