Largest cannister is approximately 6 1/2" high, 12" around, and 4 1/2" deep.  Smaller one is approximately 5 3/4" high, 12" around and 3 1/2" deep.  Both have rubber rings around the bottom of the cover. No chips or cracks. Ebay is asking for width and length, but I have listed height, circumference and depth instead.
