Cut full-height portions in a rectangular grid. Measure the edible cake, excluding decorations.
Plan equal, full-height wedges using a target portion volume and minimum outer-edge width.
A 30 × 20 cm cake cut into 5 × 4 cm portions gives 6 rows and 5 columns: 30 portions. At 8 cm tall each portion is 160 ml.

Servings = full rows × full columns. Cake height changes portion volume, not the number of full-height cuts. Internal sponge layers are not separate servings.
The unallocated edge strips are shown separately. Plan smaller party portions or larger dessert portions by changing their dimensions.
Change the inputs to match your own task. Whole packages are rounded up after allowances, so purchase quantity and actual requirement can differ. Apply each allowance once.
