Cake Size Serving Guide 

This cake Size serving guide offers a simple and convenient reference for determining the number of servings from various cake types. With this guide, you can confidently plan the cake of your dreams for weddings or parties, ensuring there's enough for everyone.

How to Determine the Cake Size

When selecting a cake size, the first thing to consider is your guest list. Begin by assessing the number of guests you plan to invite. "Keep in mind that not everyone will want a piece of cake, so you don't need to provide enough for every guest".  However, some may want seconds or wish to sample different flavors.


Generally, you can estimate that about  75  to  85 percent of your guests will want a slice. From there, decide if you want enough cake for everyone, if you'd prefer to have some leftovers, and the size of the slices you'd like to serve.

Standard cake servings for events are typically 1-inch by 2-inch slices, while larger party slices measure 1.5 inches by 2 inches.

Consider the cake sizes from the top tier to the bottom. Start by the number of servings 6-inch top offers, then proceed to the sizes in sequence:  8-inch, 10-inch, 12-inch, etc.

For example: If you require  74 servings, a three-tiered round wedding cake with a 10-inch, an 8 middle, and a 6-inch top would be adequate.

Cake Sizing Factors To Consider

Guest List

Estimate the cake size first, assess how many guests slices you will need. For instance, if you're hosting a seated dinner with the wedding cake as the dessert, you'll need a slice for each guest. Conversely, if you're offering a dessert station or family-style desserts, you may require less cake since not everyone will take a slice.

Additional Desserts

A centerpiece cake can be the highlight of a dessert table, but including treats like cookies, brownies, cupcakes and candy can reduce total amount of cake. Aim to provide enough dessert servings so that each guest can enjoy one and a half items, whether that’s a slice of cake, a cookie, a brownie.

Serving Style

It's helpful to consider your serving style when determining cake size. If you’re planning to have a plated slice served to each guest right after their meal, you’ll want to be sure you have enough cake to deliver that same slice to everybody. If you’re planning to cut the cake just before or in the middle of a dance party, chances are, not everybody on the guest list will head over to the cake table to grab a bite.
