If you’re throwing a party, the last thing you want is to run out of cake! This isn’t an exact science, and obviously depends a lot on who cuts the cake, but we’ve illustrated some of the most common sizes below and the equivalent portions of wedding and party slices to give you an idea. Read more here about the different size options.

What size slices do I need?
The first thing to consider is the portion sizes you want to offer – obviously one cake could be cut into 6 triangular portions – but cut those in half and you’ve got 12, halve again and you’ve got 24 etc – it’s just maths! For weddings and corporate events, cakes are often cut across into slices, rather than into triangular wedges from the centre. Then those slices are cut into rectangular fingers. So here are the definitions we use at Caketu:
A tiny slice is literally that – a rectangular finger-shaped mouthful or two or cake. Most portions will just have a small bit of icing from the top. Suitable for occasions where guests may have already have eaten a meal, or will be mostly chatting – e.g. at a corporate event.
Small slices are often what guests receive at weddings. These are slightly more generous than a tiny slice, but are still unlikely to include the side of the cake as well as the top.
Standard slices are more generous. What you might expect to receive at a birthday party or similar event. More likely to be triangle or wedge shaped, each portion will comprise a part of the side as well as the top.
Party slices is the name we give to more generous servings. If shop-bought cakes never deliver the number of servings the box suggests, this is definitely the size for you!
