Frequently Asked Questions

How do I calculate servings for layered cakes?

Calculate each tier separately and sum the results. Remember that bottom tiers yield more servings as they have larger diameters.

What if I want rectangular cakes?

Use the square cake calculation method (length × width) and divide by your portion size.

How does cake height affect servings?

Standard calculations assume 2-inch (5cm) height. For taller cakes, multiply results by height multiple (e.g., 1.5 for 3-inch cakes).
