Frequently Asked Questions

Questions About Cake Planning & 5iCake

Practical answers about portions, recipe geometry, custom cake pricing, and privacy.

How do I calculate what size cake I need for my guests?

First decide on the slice style: wedding finger portions are standard at 1x2 inches (approx. 2 sq in), while birthday or party slices are 1.5x2 or 2x2 inches (approx. 3-4 sq in). Divide the cake surface area by the slice area and include a 5-10% safety buffer to find your ideal pan size.

What is the scaling factor between a 6-inch and an 8-inch cake?

Because surface area follows the square of the radius (pi r squared), an 8-inch round cake has 1.78x the volume of a 6-inch cake. To scale down from 8-inch to 6-inch, divide ingredients by 1.78 (or multiply by 0.56). To scale up from 6-inch to 8-inch, multiply by 1.78.

How should an independent baker price a custom cake?

A profitable pricing model covers all costs: (Direct Ingredients + Hourly Labor + Packaging & Decor) divided by (1 - Target Margin %) + Delivery. Many bakers undercharge by ignoring their actual decoration labor and kitchen overhead.

Is 5iCake free and does it store my recipes on an external server?
