A sheet pan, also referred to as baking tray, baking sheet, or baking pan, is a flat, rectangular metal pan placed in an oven and used for baking pastries such as bread rolls, cookies, sheet cakes, Swiss rolls, and pizzas.
These pans, like all bakeware, can be made of a variety of materials. Originally made of sheet iron, today's baking trays are made of either aluminum or sheet steel that has been enameled or coated with PFAS.
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.
The earliest recorded usage of sheet pans is in Scotland, by the baker Henry A. Gillespie.
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).
Mass, thermal conductivity, and colour of the pan play key roles in achieving a uniform cooking temperature. The friction of the pan's under surface may be a safety consideration in some applications.
A sheet pan that has a continuous lip around all four sides may be called a jelly roll pan. 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 25 mm (1 in) raised lip around the edge, and come in both standard and non-standard sizes. Within each standard, other commercial kitchen equipment, such as cooling racks, ovens, and shelving, is made to fit these standard pans. In many cases, American and European sizes are matched closely enough to be used interchangeably.
Typically, for rimmed trays, each rim will sacrifice 10–20 mm (0.5–0.75 in) of baking surface along that edge. 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.
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). 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.
European standard pan dimensions are governed by GN numbers under European Committee for Standardization EN 631.
Gastronorm sizes | Dimensions |
---|---|
GN2/1 | 650 × 530 mm |
GN1/1 | 530 × 325 mm |
GN2/3 | 354 × 325 mm |
GN2/4 | 530 × 162 mm |
GN1/2 | 325 × 265 mm |
GN1/3 | 325 × 176 mm |
GN1/4 | 265 × 162 mm |
GN1/6 | 176 × 162 mm |
GN1/9 | 108 × 176 mm |
European sized trays usually come in standard depths of 20, 40, 65, 100, 150 and 200 mm.
In American sizing, the full-size sheet pan is 26 in × 18 in (660 mm × 460 mm), which is too large for most home ovens. [1] A two-thirds sheet pan (also referred to as a three quarter size sheet pan) is 21 in × 15 in (530 mm × 380 mm). A half sheet pan is 18 in × 13 in (460 mm × 330 mm); [1] quarter sheets are 9 in × 13 in (230 mm × 330 mm). [1] The half sheet is approximately the same size as the largest mass-market baking sheets found in supermarkets, and the quarter sheet is a common size for rectangular, single-layer cakes (e.g., the size used for a regular-sized box of cake mix, holding six cups of batter [2] ).
Another popular size for home baking is 10 in × 15 in (250 mm × 380 mm). [3] This pan size, traditionally used to make a jelly roll cake, is bigger than a quarter sheet but smaller than a half sheet.
Conventional U.S. Size Name | Outer width (in) | Outer depth (in) | Outer height (in) | Outer width (mm) | Outer depth (mm) | Outer height (mm) |

Values are approximate and vary based on rim size and style.
Unlike other bakeware, smaller sheet pans function as convenient task trays.
Commercial sheet pans are used for many purposes besides baking. Kitchen or cooking processes are often designed around kitchen equipment such as sheet pans, presupposing their ubiquity in most commercial food preparation areas.
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). Enclosed racks may also be ventilated or temperature controlled to some degree.
A cookie, or a biscuit, is a baked or cooked snack or dessert that is typically small, flat and sweet. It usually contains flour, sugar, egg, and some type of oil, fat, or butter. It may include other ingredients such as raisins, oats, chocolate chips, nuts, etc.
Baking is a method of preparing food that uses dry heat, typically in an oven, but can also be done in hot ashes, or on hot stones. The most common baked item is bread, but many other types of foods can be baked. Heat is gradually transferred "from the surface of cakes, cookies, and pieces of bread to their center. As heat travels through, it transforms batters and doughs into baked goods and more with a firm dry crust and a softer center". Baking can be combined with grilling to produce a hybrid barbecue variant by using both methods simultaneously, or one after the other. Baking is related to barbecuing because the concept of the masonry oven is similar to that of a smoke pit.
Cookware and bakeware is food preparation equipment, such as cooking pots, pans, baking sheets etc. used in kitchens. Cookware is used on a stove or range cooktop, while bakeware is used in an oven. Some utensils are considered both cookware and bakeware.
Outdoor cooking is the preparation of food in the outdoors. A significant body of techniques and specialized equipment exists for it, traditionally associated with nomadic cultures such as the Berbers of North Africa, the Arab Bedouins, the Plains Indians, pioneers in North America, and indigenous tribes in South America. These methods have been refined in modern times for use during recreational outdoors pursuits, by campers and backpackers.
A tray is a shallow platform designed for the carrying of items. It can be fashioned from numerous materials, including silver, brass, sheet iron, paperboard, wood, melamine, and molded pulp. Trays range in cost from inexpensive molded pulp trays which are disposable and inexpensive melamine trays used in cafeterias, to mid-priced wooden trays used in a home, to expensive silver trays used in luxury hotels. Some examples have raised galleries, handles, and short feet for support.
A muffin is an individually portioned baked product; however, the term can refer to one of two distinct items: a part-raised flatbread that is baked and then cooked on a griddle, or a quickbread that is chemically leavened and then baked in a mold. While quickbread "American" muffins are often sweetened, there are savory varieties made with ingredients such as corn and cheese, and less sweet varieties like traditional bran muffins. The flatbread "English" variety is of British or other European derivation, and dates from at least the early 18th century, while the quickbread originated in North America during the 19th century. Both types are common worldwide today.
An oven is a tool which is used to expose materials to a hot environment. Ovens contain a hollow chamber and provide a means of heating the chamber in a controlled way. In use since antiquity, they have been used to accomplish a wide variety of tasks requiring controlled heating. Because they are used for a variety of purposes, there are many different types of ovens. These types differ depending on their intended purpose and based upon how they generate heat.
A cupcake (AmE), fairy cake (BrE), or bun (IrE) is a small cake designed to serve one person, which may be baked in a small thin paper or aluminum cup. As with larger cakes, frosting and other cake decorations such as fruit and candy may be applied.
Kitchenware are the tools, utensils, appliances, dishes, and cookware used in food preparation, or the serving of food. Kitchenware can also be used in order to hold or store food before or after preparation.
A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, and advanced, large scale solar cookers can cook for hundreds of people. Because they use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide in order to help reduce fuel costs and air pollution, and to help slow down deforestation and desertification.
A génoise, also known as Genoese cake or Genovese cake, is a French sponge cake named after the city of Genoa and associated with French cuisine. It was created by François Massialot in the late 17th century. Instead of using chemical leavening, air is suspended in the batter during mixing to provide volume.
A teacake in England is generally a light yeast-based sweet bun containing dried fruit, typically served toasted and buttered. In the U.S. teacakes can be cookies or small cakes. In Sweden, they are soft, round, flat wheat breads made with milk and a little sugar, and used to make buttered ham or cheese sandwiches. In India and Australia, a teacake is more like a butter cake. Tea refers to the popular beverage to which these baked goods are an accompaniment.
A loaf is a (usually) rounded or oblong mass of food, typically and originally of bread. It is common to bake bread in a rectangular bread pan or loaf pan because some kinds of bread dough tend to collapse and spread out during the cooking process if not constrained; the shape of less viscous doughs can be maintained with a bread pan whose sides are higher than the uncooked dough. More viscous doughs can be hand-molded into the desired loaf shape and cooked on a flat oven tray.
Heavy-duty cookware made of cast iron is valued for its heat retention, durability, ability to maintain high temperatures for longer time duration, and non-stick cooking when properly seasoned. Seasoning is also used to protect bare cast iron from rust. Types of cast iron cookware include frying pans, dutch ovens, griddles, waffle irons, flattop grills, panini presses, crepe makers, deep fryers, tetsubin, woks, potjies, and karahi.
Gastronorm (GN), sometimes spelled Gastro-Norm, is a European standard for kitchenware tray and container sizes that is commonly seen worldwide in the catering and professional food industry, as well as in certain parts of the high-end consumer market. Gastronorm is generally used worldwide except in most of the United States and Canada, which have their own domestic systems. The gastronorm standard was first introduced in Switzerland in 1964 and became an official European standard in 1993 with the EN 631 standard.
Johnnycake, also known as journey cake, johnny bread, hoecake, shawnee cake or spider cornbread, is a cornmeal flatbread, a type of batter bread. An early American staple food, it is prepared on the Atlantic coast from Newfoundland to Jamaica. The food originates from the indigenous people of North America. It is still eaten in the Bahamas, Belize, Bermuda, Canada, Colombia, Curaçao, Dominican Republic, Jamaica, Puerto Rico, Saint Croix, and the United States.
A baking stone is a portable cooking surface used in baking. It may be made of ceramic, stone or, more recently, salt. Food is put on the stone, which is then placed in an oven, though sometimes the stone is heated first. Baking stones are used much like cookie sheets, but may absorb additional moisture for crispier food. A pizza stone is a baking stone designed for cooking pizza.
A kitchen utensil is a small hand-held tool used for food preparation. Common kitchen tasks include cutting food items to size, heating food on an open fire or on a stove, baking, grinding, mixing, blending, and measuring; different utensils are made for each task. A general purpose utensil such as a chef's knife may be used for a variety of foods; other kitchen utensils are highly specialized and may be used only in connection with preparation of a particular type of food, such as an egg separator or an apple corer. Some specialized utensils are used when an operation is to be repeated many times, or when the cook has limited dexterity or mobility. The number of utensils in a household kitchen varies with time and the style of cooking.
