The size is approximate. Diameter: 11 cm Height to lid: 9 cm Height including handle: 20 cm Inner diameter of tea strainer: 5.5 cm This was a gift, and I don't know what kind of pottery it is or what it's called. Since it has a tea strainer, it can be used as a teapot, but I think it would also look great as interior decoration. I'm not an expert, but it's a nice piece with a warm feel. Thank you for looking.
