Unfortunately have not checked the size. Looks pretty puny off at the wall. Cheap plastic. The price is excessive. Would actually awarded 2.5 stars ("not bad" is too good; "I do not like" -> I would have returned it had they still retain. 1. because it is absolutely noiseless 2 have sensitive children / grandchildren who sometimes spend the night in the guest room 3. since it has switched easily to standard time 4 and I was annoyed that I did not better researched. In a review was: "Digital display seconds of getting used to." Why do we need seconds? I have set to date and I like that. Finally therefore still something positive :-)
