30cm is fine for us, turned over it is bevelled and the flat area is 25cm. I have put a picture on my profile of plate in use. This is a 4 egg pavlova we generally don't make them any larger so any bigger than that the plate would be too small. A lovely blue & white spode plate would be lovely

And other large puds? Mine will be either balanced precariously on my cake stand or hanging off the side of a dinner plate this lunchtime. I think I need to treat myself to a large impressive looking platter.
