Cake cutting plan for equal slices

Enter the shape, the size and the number of slices: the calculator draws how to cut the cake into equal pieces.

How we calculate

  1. A round cake of up to 16 slices is cut into wedges from the centre.
  2. For more slices we cut an inner circle of half the diameter and divide it separately, and the outer ring into wedges, so the pieces are of a similar size.
  3. A rectangular or square cake is cut into the grid that gives the squarest pieces.

Frequently asked questions

How do I cut a round cake into 30 slices?

For Ø 30 cm: an inner circle of Ø 15 cm into 8 slices, the outer ring into 22.

How do I get neat, equal slices?

Dip the knife in hot water and wipe it before every cut; mark the centre and the halves first.

The app goes further

In the app the Cake converter counts slices of tiered cakes too, and the Order book records how many people a cake is for.
