Baking Pan Conversions
The key to successful pan swapping is matching the Surface Area (approximate volume). If the area matches, baking time and depth will be similar.
Common Equivalents
- 9-inch Round ≈ 64 sq inches.
- 8-inch Square = 64 sq inches. (Perfect swap!)
- 9x13 Rectangular = 117 sq inches. (Holds almost double a single 8-inch square).
- 10-inch Bundt ≈ 10-12 cups volume. Roughly equivalent to two 9-inch round pans.
FAQ
Can I use a square pan instead of a round one?
Yes, but be aware that an 8-inch square pan holds more batter (64 sq in) than an 8-inch round pan (approx 50 sq in). You may need to increase the recipe or reduce baking time slightly for the round pan.
How do I adjust baking time for a larger pan?
If spreading the same amount of batter into a larger pan, the layer will be thinner and bake faster. Reduce cooking time by 25% and check early. If scaling up batter to fill the larger pan to the same depth, time should be similar, maybe slightly longer.
What is the area of a 9x13 pan?
A standard 9x13 rectangular pan has an area of 117 square inches. This is roughly equivalent to two 9-inch round pans (approx 127 sq in total).
