Approximately:
5 1/2" w x 4 1/2 h x 3" d when nested
 There are two slight flaws with this set.  One, Mary sits tightly inside Joseph and takes a little more wiggling to get it to seperate than what I inteded.  Also, I had to sand a small area at the base of the stable and so that area is more matte.  The price has been discounted, but it is still a wonderful piece that brings the light of the world into your home.
