What Is a 9×13 Baking Pan? | The Pan Behind Your Favorite Recipes

A 9×13 baking pan is a rectangular pan with a 9-inch by 13-inch baking surface, totaling 117 square inches.

If you’ve ever baked a sheet cake, a pan of brownies, or a family-size lasagna, you’ve likely used a 9×13 baking pan. It’s the workhorse of American kitchens — the pan recipes call for when they mean business. The label refers to the pan’s top dimensions, and it’s a standard size that fits most ovens and most recipes without adjustment.

The numbers describe the baking surface: 9 inches on one side, 13 on the other. You’ll also see it written as “13×9,” which is the same pan, just with the dimensions listed in reverse order. It’s a rectangle, not a special category of bakeware, and its size is what makes it so versatile.

What Are the Standard Dimensions of a 9×13 Pan?

While the baking surface is a consistent 9 by 13 inches, the pan’s depth and overall size can vary. The surface area works out to exactly 117 square inches, which is the figure recipe conversions rely on. In metric, that’s roughly 22.86 cm by 33.02 cm.

Most standard pans are about 2 inches deep, which is the depth King Arthur Baking recommends for cake recipes. However, you’ll find variations. For example, Nordic Ware’s Naturals 9″ x 13″ model lists its interior dimensions as 12.1 inches long, 8.8 inches wide, and 2.5 inches high. A Doughmakers commercial-grade aluminum pan lists overall dimensions of 15.25 x 10.25 x 2.5 inches, with a 9″ x 13″ interior. So the interior space you actually bake in stays consistent, while the rim and depth can differ.

That means you shouldn’t assume every “9×13” pan holds the same amount. Published capacity is often cited at 14 to 16 cups, but because depth varies, that figure isn’t universal.

What Materials Are 9×13 Pans Made From?

You’ll find this pan in three main materials, each suited to a different job:

• Metal: The standard choice for baking. Aluminum pans like the Nordic Ware Naturals heat quickly and evenly, which helps produce golden-brown edges on cakes and brownies.
• Glass: A common choice for casseroles and lasagna. Glass holds heat well but takes longer to heat up, which can affect baking times if you substitute it for metal.
• Ceramic: Often used for serving as well as baking. Like glass, it’s great for slow-cooked dishes and looks presentable at the table.

Your choice affects how your food cooks. A metal pan promotes browning, which is why it’s preferred for cakes. For a hearty casserole that needs gentle, even cooking, glass or ceramic is often the better fit.

What Can You Cook in a 9×13 Pan?

This pan is the most versatile piece of bakeware in a standard kitchen. Bar cookies, brownies, sheet cakes, and cinnamon rolls are all classic uses. On the savory side, it’s the go-to for lasagna, baked ziti, roasted vegetables, and breakfast casseroles.

If a recipe calls for a different pan size, you can often use a 9×13 as a substitute by comparing the bottom surface areas of the pans. As King Arthur Baking explains, a 2-inch-deep pan is best for cake recipes, so you can bake a layer cake recipe in a 9×13 as long as you adjust the baking time. The food will just be thinner and bake faster than it would in a taller, smaller round pan.

If you use this pan often, a version with a lid can make storage and transport easier. Our roundup of the best 13×9 pans with lids covers tested options that keep leftovers fresh.

Safety and Care Tips

There’s no one-size-fits-all rule for oven safety since it depends on the material. One aluminum manufacturer, Doughmakers, specifies its pan is heat safe to 428°F (220°C), which covers virtually all baking. Glass and ceramic pans may have different heat limits, so it’s worth checking the bottom of your specific pan.

Cleaning is straightforward, but it also varies by material. The Doughmakers aluminum pan recommends hand washing promptly in hot, soapy water and towel drying to keep it in top shape. Many metal pans are dishwasher-safe, but hand washing extends their life and preserves the finish.

Before you buy, remember that not all “9×13” pans are created equal. Check whether the listed dimensions refer to the interior baking space or the exterior rim, and confirm the depth. A 2-inch-deep pan is the standard for cakes, while a deeper pan gives you more room for thick casseroles.
