The length and width of the barbecue grill are determined according to the size and habits of the things you bake at one time. There are no specific standards. If the height is for home use, it is enough to make a 50CM grill. If it is a professional barbecue, the barbecue chef had better stand on his arm and naturally place it at a more comfortable height. Otherwise, working all day will kill you. Generally 80-90CM. The mesh size is 1.5CM, the spacing is 5*5CM, and the distance between the furnace net and the furnace side is 8~ 10CM. Other options, not too many requirements.
