Baking Pan Sizes | Standard Dimensions & Volume Guide

Standard US baking pan sizes are defined by interior measurements in inches, with the most common home sizes being 9×2-inch round cake pans, 9×13-inch rectangular pans, and 18×13-inch half sheet pans.

Baking pan sizes in the US follow a consistent system of interior length × width × depth, but home and commercial sizes differ in ways that matter. Whether you are substituting pans or buying your first set, knowing the actual dimensions and cup capacities saves the recipe.

Round Cake Pan Sizes

Round cake pans come in standard 2-inch depth for most home recipes; tube pans run 3 inches deep. Volume scales directly with diameter.

• 6×2 inch: 4 cups (960 ml)
• 8×2 inch: 6 cups (1.4 liters)
• 9×2 inch: 8 cups (1.9 liters)
• 10×2 inch: 10 cups (2.4 liters)
• 8×1.5 inch: 4 cups (960 ml)
• 9×1.5 inch: 6 cups (1.4 liters)

Always match depth as well as diameter.

Square, Rectangular & Loaf Pan Sizes

Square and rectangular pans are usually 2 inches deep. Loaf pans are 3 inches deep for standard 9×5-inch models and 4-cup for the 8×4-inch size. Most home ovens fit pans up to 17×14 inches, so a full commercial sheet (26×18 inches) will not fit.

• 8×8×2 inch square: 8 cups (1.9 L)
• 9×9×2 inch square: 10 cups (2.4 L)
• 9×13×2 inch rectangular: 14 cups (3.3 L)
• 11×7×2 inch rectangular: 10 cups (2.4 L)
• 9×5×3 inch loaf: 8 cups (1.9 L)
• 8×4×3 inch loaf: 4 cups (960 ml)

Check your guide to the best baking pans for home bakers before buying, since some off-brands use non-standard depths.

Sheet Pan Sizes: Full, Half & Quarter

Commercial sheet pan sizes use a standard scale; the half sheet is the largest size that fits a typical home oven.

All sheet pans are typically 1 inch deep. Quarter sheets work well in toaster ovens and small convection ovens.

Specialty Pans & Measuring Tips

Bundt and springform pans have their own size conventions. A 10×3-inch Bundt holds 10–12 cups, but volume is not standardized across brands — always check the specific cup capacity. Springform 9×2.5-inch pans hold 10 cups; 10×2.5-inch holds 12 cups.

To measure a pan yourself: use the interior top edge dimensions (length × width), measure depth from the bottom inside to the top rim, and fill with water to the brim to verify volume. Many pans have the size stamped on the bottom.

Bundt-style and decorative pans from brands like Nordic Ware may differ from standard cup volumes; use water to confirm capacity before pouring in batter.
