A Baker's Guide to Sheet Pans

Baking Sheet Sizes and Differences

Whether you’re new to baking or you have years of baking experience under your apron belt, the different sheet pans available can be a bit confusing at first glance. What’s the difference between a sheet pan and a cookie sheet? Is a jelly roll pan different from a sheet pan? We’ll cover all of that and more, and you’ll be a sheet pan pro!

Before we get into the specifics of pan sizes, I want to give you a not-so-gentle nudge to read my tips for choosing baking pans. There you’ll learn about how to pick bakeware based on material, thickness, color, and more.

Now, let’s talk about sheet pans!

Full Sheet Pans

For home cooks and bakers, full-size sheet pans are not likely to be something that you’ll be able to use. Measuring 26″ x 18″ with about a 1-inch rim around the outside, it just won’t fit in most home ovens. These are designed for larger ovens in commercial kitchens like restaurants and bakeries.

Half Sheet Pans

As you might guess from the name, half sheet pans are half the size of a full sheet pan. They usually measure 18″ x 13″ with about a 1-inch rim around the outside, although you’ll see some slight variances in those dimensions.

The workhorse of many home bakers, half sheet pans are great for baking cookies and sheet cakes. For most bakers, having two of these pans will suffice. I like the flexibility of having three of these in my kitchen for those times I’m on a cookie baking spree.

Some of my favorites:

Quarter Sheet Pans

If you’re playing along here, you’ve likely guessed that a quarter sheet pan is a quarter of the size of a full sheet pan and half the size of a half sheet pan. These small pans measure 13″ x 9″ with about a 1-inch rim around the outside. (Don’t confuse this pan with a 13″ x 9″ pan you might use for something like blondies or a cake. Those have sides at least 2-inches tall.)

These pans are great for small batch cookie baking. I also use them when I portion cookie dough for freezing, as you can put lots of cookies on the pan, and it won’t take up a lot of room in your freezer while you wait on them to be ready to bag for long-term freezer storage.

You’ll likely find that these small pans are more useful than you first might think. Use them for gathering ingredients, toasting small amounts of nuts, or for small cooking jobs like roasting vegetables.

Some of my favorites:

Jelly Roll Pans

As the name implies, jelly roll pans are often used to make (you guessed it!) jelly rolls as well as Swiss rolls, which are thin cakes that are filled and rolled. They’re a bit smaller than half sheet pans, but the exact dimensions can vary. If you do a quick search for a jelly roll pan, you’ll find a few different sizes. Most commonly, they are either 10″ x 15″ or 12″ x 17″. If you remember how to measure area from your geometry classes, you’ll realize pretty quickly that that’s a pretty big difference in sizes. In fact, the latter size is fairly close to the size of a half sheet pan.

If the recipe you’re using doesn’t specify dimensions, you may have to use your best judgment about what size you need. I don’t often use a jelly roll pan, but you will find one used in a few recipes here at BoB, like Toasted Pecan Roulade and Butterscotch Cream Cheese Swirl Bars.

You can also use these pans for baking cookies and for some cooking applications. You’ll likely find, however, that trying to scale a recipe that fills a different size pan to be less than straightforward.

Some of my favorites:

Cookie sheets are designed for baking cookies and other things that don’t need a rim around the outside to prevent spilling or sliding. You definitely wouldn’t want to bake a cake or another batter on these. Stick with cookies, biscuits, scones, and other portioned doughs.

Unlike rimmed baking sheets, these pans have one or two slightly elevated sides to make it easier to get them in and out of the oven. Theoretically, the lack of a rim also allows heat to circulate around the cookies more easily.

Unless you have a particular affinity for cookie sheets, you can absolutely make use of your half sheet pans for baking cookies. I’ll tell you a little secret. I don’t think I’ve ever owned a cookie sheet, and I bake a lot of cookies.

Two-Thirds Sheet Pans

If you have a large oven, you may be able to make use of a two-thirds sheet pan. At two-thirds the size of a full-size sheet pan, these pans measure approximately 16″ x 22″. These are great for large batches of cookies.

Eighth Sheet Pans

While it’s not quite as useful as its larger counterparts, an eighth sheet pan may prove helpful to you in certain situations. These small pans measure approximately 6.5″ x 9″, which is half the size of a quarter sheet pan.

Use these little pans for small jobs like toasting a small amount of nuts or baking a few cookies from the freezer. Some small-batch baking recipes may use this size pan as well. These pans are also great for organizing your baking ingredients when you’re getting ready to bake.

Choosing Pans for Your Baking Style

If you’re replacing some or all of your baking pans, then you likely know which pans you use most often. If you’re new to baking, it can be tough to know what you need to get a basic baking setup. In either case, my best advice is to take the time to think about the types of baked goods you want to make. That should help you decide what sheet pan size you need.

If you’re a cookie baker, then I recommend starting with a couple of half sheet pans. They’ll do a great job of baking cookies, while also opening up the possibility of baking sheet cakes, scones, and other baked goods that require a sheet pan.

Taking Care of Your Sheet Pans

Depending on the material and quality of your pans, they’ll take varying degrees of care to maintain.

  • Cleaning – Most will need to be hand-washed instead of going into the dishwasher.
  • Lining – If you’re using parchment paper or a silicone mat to line your pans, then keeping them clean should be fairly simple. If you prefer to bake directly on the pan, then you’ll need to do a more thorough cleaning, and the pans may not last as long.
  • Avoiding scratches – Take care not to scratch your pans with knives or other sharp tools. A cookie spatula is handy for removing cookies without scratching the pan. Lining pans will help with this as well.
  • Longevity – If well cared for, a good quality baking sheet should be durable enough to last several years. If you have nonstick baking sheets, pay attention to any damage to the coating as that will affect how things bake.
  • Warping – If you weren’t already aware of it, the telltale popping sound when your baking sheet is in the oven lets you know that your pan has warped. A warped pan is no longer a flat surface, so it can affect the end result of your baking.

Tips for Choosing Baking Pans

Aluminum, stainless steel, shiny, dark, light, non-stick…. There are a lot of options when it comes to baking pans. For further reading about what to consider when choosing pans based on material, color, and more, see my tips for How to Choose Baking Pans.

  1. You did not mention eight sized pans – 9 x 6. They are some of the most useful pans in my kitchen. they are great for baking, broiling for 1 or 2 people. I also use them to pre-salt steaks/chops prior to cooking. I have 4 of them and use them constantly. I also own the other sizes you mention and all are useful. My only issue with the eight sized pan is the 2 manufacturers do not also make cooling/baking racks to fit these pans. I have several small racks but they are too narrow and leave a space next to the pan edge.

  2. What size sheet pan do I need ( snd thickness) to bake a number cake?

  3. Finally! I understand Jelly Roll pan. Thank you!

  4. Does anyone know if anyone makes a 15x 18 sheet pan to fit in my small wall oven and also my very special bakers speed rack that is 15 inches wide? Can not find them! Thanks
