<P> Professional sheet pans used in commercial kitchens typically are made of aluminum , with a 1 in ( 2.5 cm ) raised lip around the edge , and in the United States come in standard sizes . The full - size sheet pan is 26 by 18 in ( 66 by 46 cm ) , which is too large for most home ovens . A two thirds sheet pan ( also referred to as a three quarter size sheet pan ) is 21 by 15 in ( 53 by 38 cm ) . A half sheet pan is 18 by 13 in ( 46 by 33 cm ) ; quarter sheets are 9 by 13 in ( 23 by 33 cm ) . The half sheet is approximately the same size as mass - market baking sheets found in supermarkets , and the quarter sheet is a common size for rectangular , single - layer cakes . Other commercial kitchen equipment , such as cooling racks , ovens , and shelving , is made to fit these standard pans . </P>
