The largest standard niche width for a range hood is 90 centimeters. A range hood of this size exhausts a lot of cooking fumes. You can use a range hood that is 90 centimeters wide above a large cooktop or large stove with 5 or 6 burners. A range hood of this size has a higher exhaust capacity and is also suitable for a large or open kitchen. Make sure the range hood isn't too high or too low, otherwise it won't exhaust all cooking fumes.
