How wide does your hood fan need to be?
How wide does the ventilation hood need to be? This depends firstly on the width of the cooktop and secondly on the size of your kitchen. It is important for the ventilation hood to be slightly wider than the cooktop below it. Only then can you ensure that the hood captures all the rising steam and cooking vapours and performs at its best. If there is not enough space for this, then the ventilation hood should be at least as wide as the cooktop. Find out more about "Appliance widths"
