what are the dimensions of a half sheet cake pan
Sheet pan 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.[1] 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).[2][3] 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.
