Electric cooktops range in size from 15-inch models to 48-inch designs. However, the most common electric cooktops are between 30 and 36 inches because they correspond to the most common cabinet widths.
The bigger the cooktop, the more burners you can expect to come with the model. A standard cooktop usually features four burners, enabling you to fit four medium-sized pots and pans simultaneously. But if you have a large family to cook for or often use your hob with lots of big pots and pans on the go, you may want to consider a cooktop with more than four burners.
That way, you can cook multiple foods anytime without worrying about your pots and pans fitting. Essentially, the size of your electric cooktop matters because it will impact how you cook. You want to strike a balance between functionality and space.
