Dimensions for cartons in the tube and tray styles are expressed as length, width, and depth. Length and width are measured at the open or fill end of the carton. Length is the larger dimension at the open end of the carton. Width is the smaller dimension at the open end and should be given second. Depth is the distance between the open ends of a tube, or from the open end to the bottom of a tray, and should be given third.
