In the United States, a full sheet pan is 26 x 18 inches, a two-thirds (three-quarter) sheet is 21 x 15, a half sheet is 18 x 13, a quarter sheet is 9 x 13 and an eighth sheet is about 9.5 x 6.5. The half sheet is the size most home recipes mean. This chart gives every standard size with metric equivalents.
Sheet Pan Sizes Chart

| Two-thirds (three-quarter) sheet | 21 x 15 | 530 x 380 |
| Half sheet | 18 x 13 | 460 x 330 |

Sizes are approximate outer dimensions and vary with rim size and style. A rim around 1 inch tall is typical.
Which Sheet Pan Fits Your Oven
A full sheet is too large for most home ovens, so it is used in commercial kitchens. Check the width and depth inside your oven before buying a two-thirds sheet. The half sheet is approximately the same size as the largest mass-market baking sheets sold in supermarkets, and it is the safest choice for a standard range.
European Tray Sizes
European baking trays follow gastronorm (GN) sizes, set by the standard EN 631. A GN 1/1 tray is 530 x 325 mm, GN 2/3 is 354 x 325 mm, GN 1/2 is 325 x 265 mm and GN 1/3 is 325 x 176 mm. The standard depths are 20, 40, 65, 100, 150 and 200 mm.
Sheet Pan vs Cookie Sheet
A sheet pan has a raised rim on all four sides, which keeps juices and batter from spilling and makes it suitable for roasting, sheet cakes and bars. A cookie sheet has a rim on one or no sides, so cookies slide off easily. Both come in the sizes above.
Choosing the Right Size for the Job
- Roasting a whole meal: half sheet, spread out so food browns rather than steams.
- Single-layer cake: a quarter sheet suits a box of cake mix, which makes about six cups of batter.
- Jelly roll cake: the 10 x 15-inch pan.
- Small oven or one person: quarter or eighth sheet.
Caring for Sheet Pans
Line pans with parchment paper for easy cleanup and to reduce warping and sticking. Avoid putting a hot pan in cold water, because sudden temperature changes can warp the metal.
