Ice Tray Size: Our BPA-free ice tray mold size is 5 inches wide, and 10.3 inches long, and each cube size is 1.3 inches wide. There are seven rows of three ice cubes in each tray, which can be combined into a total of 42 ice cubes at one time. Like other trays, place more ice cubes in the same space and contact with the insulating silicone surface to make the ice cubes freeze faster, so you can replenish and maintain the inventory throughout the night.
