8 1/4 inches.  4 soup bowls.  Some wear to the gold paint on the inner circle.  No chips, cracks or fleabites.  And please check out the rest of this set to save on combined shipping costs.  

                

Domestic shipping and handling in the U.S. is $27.50.  Foreign bidders are welcome with the shipping costs to be determined after the auction is finished. I will combine shipping. I have decided to sell my collection of antiques (and other nice items), which I have been collecting for the past 30 years.  Good luck with your bids.
