Stove/Oven Height. When it comes to height, there are some variations. Average heights for a stove/oven combo are either 37.25 inches or 47 inches, depending on the manufacturer. The most common height of 36 inches accommodate standard counter heights.
Cooktops generally run 30 or 36 inches wide, although some new models can be even larger. Four burners fit on to a 30-inch cooktop, while five or six burners fit on the 36-inch models. Make sure you buy a cooktop that will fit in the space youve allotted for it in your home. Some individuals choose to install cooktops directly over built-in ovens. This is possible if the oven measurements coincide with the size of the cooktop. Most standard wall ovens are either 24, 27 or 30 inches wide.
