10 7/8 inches in diameter.  The white flowers are raised.  Very nice plate to add to your collection.  

                

Domestic shipping and handling in the U.S. is $9.50.  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.
