Finding the perfect cake is an important part of any big day! But it can be hard to visualise how much you’ll need to ensure every guest who wants some gets to enjoy a piece. That’s why we’ve put together our handy wedding cake size guide! Here, you can figure out how big your cake should be – with a little help from our friends at Wilton, too…
What do you need to decide first?
Before ordering or making your wedding cake, there are a few pieces of information you need to have to hand.
- How many guests are you planning to have?
- What shape of cake are you going for?
- What’s your budget?
In this post, we’ll be going in to the first two points, but the third is important to factor in. If you are having a professional cake artist make your wedding cake, your budget will likely impact on the size of cake you go for. Just something to keep in mind!
Another thing to keep in mind is that it’s likely not every one of your guests will want a piece of cake. Some might not like your chosen flavours (can’t please everyone!) and some might not even be “a cake person” (gasp, shock, horror, we know!). A very rough estimate is that 10% of your guests will not want a piece of cake.
Having said that, you might also want to factor in some cake for yourselves after the big day! Take your time to think all of this over before committing.
Wedding Cake Size Guide by Shape:
It’s easy to get caught up in the number of guests you are having. However, it isn’t quite as simple as asking “what size of wedding cake do I need for 100 guests”. It all comes down to the shape!
Please note, if you are having a cake artist make your cake, this is an important discussion to have with them – they may use their own sizing guides based on the size of their tiers.
Our friends at Wilton created the sizing guide we are using here, all based on 4″ high cake tiers. Servings are based on slices that measure about 1 x 2 inches in size, which is a fairly typical size of slice for a wedding cake.

The classic! A round cake is a common choice for weddings. There’s a simple and traditional feel to a round cake that can allow the decorations to do the talking!
Each of these numbers is based on a 4″ high tier. So, for example, a 4″ high x 8″ wide tier would give you approximately 24 servings.
Looking for something modern and eye-catching? A square cake might be just what you want. This is an increasingly popular choice for a reason.
Again, these servings are based on a 4″ high tier. So, a 4″ high x 8″ wide tier would give you approximately 32 servings.
Heart Shaped Cake
Embracing the romantic vibes? What better time to do it! A heart shaped cake is a little more quirky and can be a really lovely way of personalising the cake.
In the same format as the other shapes, these servings are based on a 4″ tier. So, a 4″ high by 8″ wide tier would give you approximately 22 servings.
And finally, the sheet cake! With this more rectangular shape, you can get more servings out of less tiers – it all depends on the look you want to go for.
In this case, a 7″ wide x 11″ long x 4″ high sheet cake would give you approximately 32 servings.
We hope our wedding cake size guide has been helpful. Planning a wedding might be overwhelming, but knowing you’ve got the perfect cake covered (pardon the pun) is one of the best things to tick off the list!
