Size matters
At the same batter depth, changing from a 20 cm to a 24 cm diameter tin multiplies ingredients by 1.44, not 1.20. We compare areas and also account for depth if you change it.

What do you need to calculate?
Practical tools for everyday cooking.
Let’s work on your recipe.
Enter the internal dimensions of your tins. We will do the maths.
Common sizes
Use the same depth to keep the same thickness. This is the batter depth, not the tin height: leave room for rising.
The same recipe, for your number of guests. Original quantities stay unchanged.
Enter each ingredient’s pack price and pack quantity. Use the same unit as in your recipe.

Original recipe quantitiesThree things worth knowing.
What about half an egg?
If you need a fraction of an egg, beat it and weigh the required proportion. You can also enter eggs directly in grams for a more practical measurement.
Work out the real cost
An ingredient’s cost is its pack price divided by the pack quantity, multiplied by the quantity used. Add packaging, energy or other costs separately if you want to include them.
Frequently asked questions
Does this work for every tin?
We calculate straight-sided cylindrical and rectangular tins. Ring tins, sloping sides and special shapes need a different calculation. Always use internal dimensions.
Should I change the baking time?
Possibly. This tool scales quantities, not time or temperature. Batter depth, tin material and your oven affect baking. Keep an eye on your recipe and check doneness.
Where is my recipe saved?
Only in this browser’s local storage, if available. Nothing is sent to a server. Clearing browser data may erase it; download a copy to keep it.
Are cups and grams interchangeable?
There is no single conversion: it depends on the ingredient. We keep the unit you enter. For costing, the pack and the recipe must use the same unit. Eggs are treated as individual units or grams, as selected.
