The standard opening for a stove can vary depending on the type and model of the stove. However, in general, a standard stove opening in a kitchen typically measures 30 inches (76 centimeters) in width. This size is commonly referred to as a "30-inch stove opening." It is important to note that there can be variations, and some stoves may require a larger or smaller opening depending on their dimensions. It is always recommended to consult the manufacturer's specifications or installation instructions for the specific stove you are considering or currently have to ensure proper fitting.
