In bread baking, especially, the bread dough will often go through several long rest intervals on sheet pans stacked in open or enclosed sheet pan racks (sometimes mounted on wheels). Kitchen or cooking processes are often designed around kitchen equipment such as sheet pans, presupposing their ubiquity in most commercial food preparation areas.
Some vendors supply quarter sheets that are half the size of a half sheet in outer dimension, while other vendors supply quarter sheets that are closer to half the size of a half sheet in flat baking area.Institutional use Mobile sheet pan rack for shallow baked goodsCommercial sheet pans are used for many purposes besides baking. While nominally half the size-and typically sharing one dimension-quarter sheets will not necessarily nest inside a half sheet side by side (whether for storage or other purposes). Pans of a single design from a single vendor will usually share the same rim height and rake across all tray sizes in a series, thus the sacrifice of flat baking surface is proportionally greater (relative to outer dimension) for small pans than for large pans. Typically, for rimmed trays, each rim will sacrifice 0.5–0.75 inches (1–2 cm) of baking surface along that edge.

In many cases, American and European are matched closely enough in size to be used interchangeably. Within each standard, other commercial kitchen equipment, such as cooling racks, ovens, and shelving, is made to fit these standard pans. 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. A half sheet pan is 18 by 13 in (46 by 33 cm) quarter sheets are 9 by 13 in (23 by 33 cm). A two thirds sheet pan (also referred to as a three quarter size sheet pan) is 21 by 15 in (53 by 38 cm). In American sizing, the full-size sheet pan is 26 by 18 in (66 by 46 cm), which is too large for most home ovens. European pan dimensions are governed by GN numbers under European Committee for Standardisation EN 631. A pan that has at least one side flat, so that it is easy to slide the baked product off the end, may be called a cookie sheet.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. Unlike other bakeware, smaller sheet pans function as convenient task trays.Contents1 Types and sizes2 Institutional use3 See also4 References5 External linksTypes and sizesA sheet pan that has a continuous lip around all four sides may be called a jelly roll pan. The friction of the pan's under surface may be a safety consideration in some applications.
Mass, thermal conductivity, and colour of the pan play key roles in achieving a uniform cooking temperature. Common features that may be found in sheet pans include: one or more flat edges to assist food removal, one or more raised edges (lips) to retain food, a contiguous rim to retain either food or shallow liquid, handles to assist in moving the pan into and out of the oven, a layer of insulation (typically air) designed to protect delicate food from burning (air bake pan), or perforations to aid in speeding cooking (pizza tray).Rigidity of the pan is especially important if the pan is to be placed directly on a flat heat source (hearth stone, induction element, etc.) Rims and ridges contribute to rigidity.
Commercial pans are sometimes made from aluminized steel which combines the conductive, reflective, and food adherence properties of aluminum, with the rigidity, mass, and strength of the inner steel core (in this process, the aluminum surface is typically 90% aluminum and 10% silicon, which is not quite the same as pure aluminum). The most basic sheet pan is literally a sheet of metal. It is often used for baking bread rolls, pastries and flat products such as cookies, sheet cakes, Swiss rolls and pizzas.These pans, like all bakeware, can be made of a variety of materials, but are primarily aluminum or stainless steel.
