Bottom diameter
The diameter of the bottom of a pan that has a round shape.
This parameter is necessary first of all in order to assess the compatibility of the pan with a particular burner on the stove. It is especially relevant if the product is planned to be used on an electric stove: the diameter of the burner must be at least not less than the diameter of the bottom, otherwise the heating will turn out to be uneven and inefficient. And in induction electric stoves (see "Functions and capabilities — Induction bottom"), these diameters must match at all. The selection of suitable frying pans is somewhat simplified by the fact that modern
electric stoves usually have burners of different diameters, and in some models the heaters can even be adjusted in size — up to autofocus in separate induction cookers). However, even in such cases, it's ok to clarify whether the pan fits into the range of suitable sizes.
Wall height
The height of the walls is selected by the manufacturer depending on the type of pan (see above) and its size, however, similar products may vary in the height of the sides. In such cases, it is worth considering the features of the intended application. So, high sides are convenient for stewing, preparing sauces and other types of cooking that involve a large amount of liquid; in addition, they allow you to fit more content. On the other hand, deep pans are more expensive and heavier. The shallow depth, in turn, makes it easy to flip pancakes, omelettes and other similar dishes, but reduces capacity.
