The large pan Which would hold the water for the double boiler measures from handle edge-to-edge of pot 13 and 1/2 in. The actual pot is 6 in 1/4 inches. The inside pot that sets down along the edge for melting chocolate or making sauces measures 6 and 3/4 inches across. The overall size from Edge to the end of the handle is about 12 and 3/4 inches. The inside of the cooking pot has lost its gloss finish. Although I think I would still use this pot the other pot obviously has been dried out once. Great Decor piece. Stacks nice. Great color. Overall measurement of this unit is about 14 in across it stands 10 and 1/2 in tall. It is light but we'll have to be packed in a larger box.
