Baking Sheet Sizes
Baking sheets are essential cookware for most bakeries, restaurants, and cafeterias. While baking sheets and bun pans come in multiple sizes, all have 1-inch-high rims. Full-size baking sheets measure over 2 feet long and 1 foot wide and are made to completely fill a commercial oven rack. Smaller options, like half- and quarter-size sheets, enable users to place multiple pans on a single oven rack.

Standard Baking Sheet Sizes Explained
Full Sheet
The largest baking sheet available at 26 inches long by 18 inches wide, these are designed to fill an entire commercial oven rack and work best for proofing, baking, and roasting in large batches.
Two-Thirds Sheet
Less common in commercial kitchens, two-thirds sheets are akin to full sheets for home chefs, as they're the largest sheet that can fit in most residential ovens. However, home cooks usually prefer half-size sheets, since they're easier to manage and clean.
Half Sheet
Half-size sheets measure 18 inches long by 13 inches wide. These pans are ideal in 20-inch-wide space-saving ovens and are typically used for small- to medium-sized applications, such as roasting a chicken or vegetables for immediate service.
Quarter Sheet
Measuring 13 inches long by 91/2 inches wide, quarter-size sheets serve as small pans for precise pastry baking, warming individual portions, or holding meal prep ingredients.
Eighth Sheet
Eighth-size sheets are the smallest size, measuring 91/2 inches long by 61/2 inches wide. They work well for individual portions and can fit in smaller appliances like toaster ovens. Eighth sheets are occasionally used for food prep or as casual restaurant serving trays.
How to Choose the Right Baking Sheet Size
When deciding which baking sheet sizes to purchase, consider the following factors:
- Operation style: Cafeterias and bakeries rely on full pans for batch baking, while restaurants offering made-to-order meals benefit from quarter- or eighth-size pans
- Menu: Baked goods and roasted vegetables need space for expanding or browning, but roasted meats cook better in smaller pans that contain their juices
- Oven size: Space-saving and half-size ovens accommodate half-size or smaller pans
Other Types of Baking Sheets
- Jelly Roll Pans: Rimmed baking sheets specifically sized for baking jelly rolls
- Perforated pans: Enable airflow through the bottom for crisping buns and other baked items
- Cookie sheets: Single-side design promotes airflow when baking cookies and pastries

Baking Sheet Sizing FAQ
What is the standard size of a baking sheet?
Full- and half-size baking sheets are the most common in commercial kitchens. Full-sized baking sheets measure 26 inches long by 18 inches wide, and half baking sheets are 18 inches long by 13 inches wide.
What is considered a large cookie sheet?
Full-size cookie sheets (26 x 18 inches) are the largest sheets available.
Can I use different pan sizes for my recipes, and what should I consider?
Yes, but always make sure your ingredients fit into the pan, and that baked items have ample room to rise. Overcrowding roasted vegetables can inhibit browning. Also, when cooking an item that releases liquid during cooking, like a cut of meat, opt for a small pan to keep its juices contained.
Is a 9 x 13 baking sheet a cookie sheet?
Standard quarter-size baking sheets measure 13 inches long by 91/2 inches wide. Cookie sheets do come in this size, but for larger batches, it's best to use full- or half-size sheets depending on your oven size.
Are half sheets half as long as full-size baking sheets
No. Half-size sheets derive their name from the fact that their pan area is half that of full-size sheets. A full-size pan has 468 square inches of cooking space; half-size pans have 234.
