Baking Pan Size Converter
Convert between baking pan sizes and find equivalent pan volumes to scale any recipe. Free online baking pan converter for round, square, rectangular, and springform tins.
Understanding Baking Pan Conversions
Pan size affects baking time and texture. Using the wrong size causes overflow or dry results. Volume calculations help you find the right substitute pan.
Calculate pan volume by multiplying length times width times depth for rectangular pans. For round pans, use pi times radius squared times depth.

|---|---|---|
| 8 inch round | 9 inch round | 1.3 |
| 8 inch round | 9 x 13 inch | 2.5 |
| 9 inch round | 9 x 13 inch | 1.8 |
| 8 x 8 inch square | 9 x 13 inch | 1.8 |
| 9 x 9 inch square | 9 x 13 inch | 1.4 |
| 9 x 13 inch | 8 x 8 inch square | 0.55 |
Baking Time Adjustments
- Thinner batter layers bake faster. Reduce time by 5-10 minutes for larger pans.
- Deeper pans need longer baking. Add 5-15 minutes for smaller, deeper pans.
- Check doneness 5 minutes before the original recipe time.
- Use a toothpick or cake tester to check the center.
- Reduce oven temperature by 25°F when using darker metal pans.
Frequently Asked Questions
Can I use a 9 x 13 pan instead of two 9 inch rounds?
Yes. A 9 x 13 pan has similar volume to two 9 inch round pans. Bake as a sheet cake and adjust time. Check for doneness 5-10 minutes earlier.
What if my pan is slightly larger than the recipe calls for?
Your baked goods will be thinner and bake faster. Reduce baking time by 5-10 minutes. Expect a slightly different texture with more surface browning.
How do I convert a recipe for a different pan shape?
Calculate both pan volumes. Divide new pan volume by original pan volume. Multiply all ingredients by this factor. Adjust baking time based on batter depth.
Does pan material affect baking?
Yes. Dark pans absorb more heat and brown faster. Glass pans retain heat longer. Light aluminum pans reflect heat. Reduce temperature 25°F for dark or glass pans.
