What size cake do I need?

Updated: May 8

A handy guide to help you decide what size cake you need!

Deciding what size cake you need can be very difficult.

Everyone has their own idea of what size a slice of cake should be. Pop into a cafe and you are served an enormous doorstep wedge, but go to a wedding reception and you are greeted with a dainty little finger slice. Different circumstances require different sized cake portions...which makes the question "what size cake do I need for 50 people?" quite hard!

Let me make it easy for you.

I have created a visual guide below to show you the portion sizes you will get from both my sandwich cakes and my tall cakes. So it will help you know how much cake you need!

First things first...sandwich cake or tall cake?

I offer TWO styles of cake - a traditional sandwich cake and the more modern tall cake. This guide will help you understand the portions you get out of each style of cake.

Here are some benefits of each style to help you choose:

Let's look more closely at TALL cakes

Here are the dimensions of one of my tall cakes - my classic Let's Party Sprinkle Cake :

This tall 6" wide cake is easily portioned into 13 by using the 13 handy rosettes around the edge of the cake.

Thirteen lovely slices

(it's not bad luck when its slices of cake)

My TALL cakes have 4 lovely layers of sponge sandwiched with buttercream...and depending on the flavour you choose homemade jam, salted caramel or lemon curd too!

Getting MORE from your TALL cake

If you are serving children or just want to offer dainty portions of cake...slice the portion in make 26 portions!

Need a bigger cake?

The TALL cake used in the example is 6" wide, but comes in a range of different sizes.

Using this 6" wide cake as a guide, I have created the portion guide below for my smaller and bigger cakes.

Have a look at the portion guide for all my TALL cakes below:

SANDWICH cake more your style?

Let's take a closer look...

Fabulous for tea time...sandwich cakes slice really well and are easy to portion like my Victoria Sponge cake here..

My sandwich cakes come in a variety of sizes, use this handy portion guide below to help you choose which size is right for you...

I really hope that this guide helps you feel confident in selecting the right size cake...but of course please do ask me using my contact details if you have any extra questions and I'll be more than happy to help!
