Pan Conversion Tips

  • 🍰Layer cakes: Fill pans 1/2 to 2/3 full for proper rise.
  • ⏱️Baking time: Adjust by 5-10 min per inch of size difference.
  • 🌡️Temperature: Larger pans may need 25°F lower temp to prevent burning edges.
  • 📏Depth matters: A 3" deep pan holds more than a 2" pan of the same width.

Understanding Pan Size Conversions

Area vs. Volume

Pan conversions are based on baking area (for thin batters like brownies) or volume (for thicker batters like cake). Our calculator uses area for the most accurate results with typical recipes.

Baking Time Adjustments

When changing pan sizes, baking time changes too. Larger pans with thinner batter cook faster. Smaller pans with deeper batter need more time. Always test with a toothpick!

Common Pan Equivalents
