The standard size of an ordinary oven is 50x30x30cm, while the conventional size of an embedded oven is 595x590x560mm. There are generally two kinds of household ovens, desktop and embedded; If you buy a desktop, the volume of the inner container should not be too small, about 30L, which is suitable for a family of four. If you buy an embedded one, the inner container has enough volume, but you need to reserve a cabinet in advance.
