The most “standard” range size is about 30 inches wide, 27–29 inches deep and 36 inches tall. Keep in mind these measurements do not include the backguard, handles, knobs or grates. The second most “standard” stove size is 36 inches wide, so consider this if you want an extra burner or element.
Stove sizes fluctuate more in width than in depth or height, since most countertop and cabinet dimensions are standardized. The goal is for your range to fit mostly flush with the top of your countertops and the front of your cabinets, with the door only sticking out an inch or two beyond cabinets.
