Cake Pan Batter Volume Calculator

Measure any cake pan precisely: round, square, rectangle, springform, or bundt. Convert inches to cups and milliliters, adjust for desired fill depth, and scale recipes between pans with confidence. Compare volumes, see percent fill and headroom warnings, and get smart tips for batter redistribution and bake time adjustments. Designed for professional accuracy, friendly for home bakers. No guesswork, just results.

Pan Comparison & Scaling

Pro tools: multi-shape • scaling • fill safety

Choose your source pan (A) and target pan (B). Enter interior measurements in inches. Depth is the wall height; we apply your desired fill to compute recommended batter volume.

Typical cakes: 60–70% to allow rise and headroom.
Pan A (source)
Pan B (target)

FAQs

How accurate is this calculator?

It uses geometric formulas for each pan shape and converts cubic inches to cups and milliliters. Accuracy depends on interior measurements and how level batter sits. Rim thickness or fluting can slightly change capacity.

What fill percentage should I use?

Most butter and oil cakes do well at 60–70% fill. Chiffon and angel food batter expand more, so use 50–60%. Cheesecakes typically fill to 80–90% since they rise little.

Can I convert a recipe from a round pan to a rectangle?

Yes. Set your original round as Pan A and your target rectangle as Pan B. The scale factor tells you how to resize the ingredients. Adjust bake time based on thickness: thinner layers bake faster.

How do I measure a bundt pan?

Measure the outer diameter, the inner tube diameter, and the depth at the lowest interior point. The calculator subtracts the tube’s volume from the outer volume to estimate usable capacity.

Why do my results differ from package capacity claims?

Manufacturers often quote “to-rim” capacity. This tool reports recommended batter based on your chosen fill percentage, which leaves headroom for rise and reduces overflow risk.

Do metric inputs work?

Enter dimensions in inches. Outputs include cups and milliliters. If you only know centimeters, divide by 2.54 to get inches before entering values.

Any baking adjustments after scaling?

Keep oven temperature the same unless thickness changes a lot. For significantly deeper batter, reduce temperature by ~25°F and extend bake time. Begin checking doneness earlier for thinner layers.
