Sheet Pan Sizes Explained

- Commercial kitchens and bakeries
- Large batch baking
- Professional baking operations
Dimensions: 18 inches × 13 inches (46 cm × 33 cm)
Half sheet pans are the most popular size for home baking. They fit most standard home ovens and offer the perfect balance of size and versatility. This is the size most recipes refer to when they mention a "baking sheet" or "sheet pan."
Best for:
- Most home baking tasks
- Cookies, roasted vegetables, sheet cakes
- Standard home ovens

- Small batches of cookies or snacks
- Toaster ovens
- Multiple pans in one oven
Dimensions: 9 inches × 6.5 inches (23 cm × 17 cm)

- Very small batches
- Single servings or small portions
- Compact ovens or toaster ovens
How to Choose the Right Sheet Pan Size
Before purchasing a sheet pan, measure your oven's interior dimensions. You need at least 1 inch (2.5 cm) of clearance on all sides for proper air circulation.
Tip: Most standard home ovens are at least 20 inches wide and 15 inches deep, which comfortably fits a half sheet pan (18" × 13"). Measure from the inside edges of your oven rack.
Recommended: Half Sheet Pan (18" × 13")
This is the most versatile size for home baking. It fits most standard ovens and is large enough for most recipes while still being manageable to handle and store.
Recommended: Quarter Sheet Pan (13" × 9") or Eighth Sheet Pan (9" × 6.5")
Toaster ovens vary in size, but most can accommodate a quarter sheet pan. Measure your toaster oven to be sure, and consider an eighth sheet pan for very compact models.
Recommended: Full Sheet Pan (26" × 18")
Commercial ovens are designed to fit full sheet pans. These are essential for large-scale baking operations and professional kitchens.
Sheet Pan Usage Tips
Always leave at least 1 inch (2.5 cm) of space around your sheet pan in the oven. This allows hot air to circulate properly, ensuring even baking and browning.
When using multiple pans, use quarter or eighth sheet pans to fit more in your oven. Rotate pans halfway through baking for even results.
Half sheet pans are the easiest to store in standard kitchen cabinets. Consider your storage space when choosing pan sizes, especially if you plan to own multiple pans.
