Full-size foil pan, also known as a standard or commercial-size foil pan, is a type of disposable baking and roasting pan made of aluminum foil. These pans are widely used in commercial and home kitchens for a variety of applications, from baking and roasting to transporting and serving larger portions of food.

The specific dimensions of a full foil pan can vary slightly between manufacturers, but they generally fall within the following ranges:

Length:

• Typical range: 12 to 18 inches
• Common sizes: 13 inches, 15 inches, 18 inches

Width:

• Typical range: 10 to 12 inches
• Common sizes: 10 inches, 12 inches

Depth:

• Typical range: 2 to 3 inches
• Common sizes: 2 inches, 2.5 inches, 3 inches

The larger size of a full-size foil pan, compared to smaller disposable foil pans, allows for cooking or transporting larger quantities of food. This makes them useful for things like roasting a whole turkey or ham, baking multiple casseroles at once, or transporting large platters of food for catering or events.

Full-size foil pans are often used in commercial kitchens, catering operations, and large households where the ability to cook or transport larger portions is beneficial. Their disposable nature and easy clean-up also make them a popular choice for these applications.

When selecting a full-size foil pan, it's important to consider the specific dimensions needed for your intended use, as well as the depth of the pan which can affect how much food it can accommodate. With their versatile size and convenience, full-size foil pans remain a staple in many kitchens.
