How to use
- Enter the original (From) and target (To) pan shape, size, and unit.
- Choose area or volume mode and add height if needed.
- Use the factor to scale your batter or ingredient amounts.
Enter pan sizes
Fractions like 8 1/2 are supported. Pan dimensions vary by brand, so use inner sizes when possible. Changing the unit does not auto-convert numbers (e.g., 8 cm → 8 in).

Area vs. volume
Area mode assumes the same batter height. Volume mode uses height for a more accurate batter volume match.

Notes
- Pan dimensions vary by brand. Use inner dimensions when possible.
- Changing pan size may affect bake time because batter thickness changes.
- Use volume mode if you want to match batter volume more precisely.
FAQ
What is the difference between area and volume mode?
Area mode assumes the same batter height. Volume mode uses pan height to match batter volume more precisely.
Should I enter inner or outer dimensions?
Use inner dimensions if you know them. Pan shapes and corner curves vary by brand, so treat results as estimates.
How do I convert a round pan to a square pan?
The scaling factor is based on bottom area. A larger factor means more batter; the same amount would bake thinner.
Does a different pan size change bake time?
Thicker batter usually needs more time and thinner batter less time. Adjust by checking color and internal doneness.
How do I apply the factor to ingredients?
Multiply ingredient amounts by the factor. You can also paste ingredients into the recipe scaler tool to scale everything at once.
