Approximately:
5 1/2" w x 4 1/2 h x 3" d  when nested
This set is my favorite this year!  There is a slight flaw in the color layer of the gold arch, but it in no way detracts from the beauty of the piece.   The price has been lowered to account for the flaw.  Jesus is the light of the world as depicted by the circle in the manger, ans is perfect in every way.
