Approximately 25.5 cm in diameter. As shown in the 3rd and 4th photos, there are minor scratches on the surface, but they are not noticeable when in use. I lightly washed it with water before listing it. Please refrain from purchasing if you are sensitive to imperfections or seek a perfect item. I also have other tableware items for sale, so I would be happy if you could take a look. Thank you. Royal Copenhagen Frijsenborg Flowers Flower Tableware Large Plate Plate
