Looks plenty big to me, at least for now. How long is he in there? For me the crate is for sleeping/rest time. Dogs need room to turn around and rest comfortably but not necessarily be sitting or standing (however I don't crate my dog other than travel/training away from home once they are house-proven, and if we have a long drive I use a larger crate than necessary).
