How to Choose the Right Cake Size for Your Celebration – The Complete Serving Guide

Planning a celebration? Choosing the wrong cake size can be one of the biggest event-day frustrations. Order too small, and you’ll run out before everyone’s had a slice. Order too large, and you may be left with more leftovers than you can store. That’s where our cake size guide comes in, helping you match the perfect cake to your guest list, event style, and appetite.

At Dello Mano, we’ve been baking handmade celebration cakes for over 18 years, delivering to Brisbane, the Gold Coast, and the Sunshine Coast. Whether you’re hosting an intimate family gathering, an elegant dinner party, or a milestone birthday with a big guest list, this cake size guide will make sure every guest gets their slice of luxury

Cake isn’t just dessert, it’s the centrepiece of your table and a moment everyone looks forward to. Choosing the right size ensures:

• Enough portions for every guest (without awkwardly thin slices).

• A balanced budget, you’re not over-ordering unnecessarily.

• The perfect look on your table, proportionate to your event scale.

For most occasions, our cakes for 8–10 people are the versatile sweet spot, big enough to serve a small crowd, yet manageable for smaller fridges. But depending on your needs, smaller or larger sizes might be perfect.

Perfect for intimate celebrations, think family dinners, anniversaries, or a small office treat. These small cakes for 4–6 people are also ideal when:

• You’re serving multiple desserts at a dinner party.

• You want to enjoy cake without too many leftovers.

• You’re gifting a cake to someone who lives alone or in a small household.

Pair it with champagne for a romantic anniversary, or bring it along to a Sunday lunch with friends, small in size, but big on flavour and presentation.

This is one of the most popular options in our cake size guide for intimate gatherings and thoughtful gifting.

The star of most celebrations. Our cakes for 8–10 people suit dinner parties, milestone birthdays, or team gatherings. They’re also perfect if you enjoy having a few slices left for the next day, because our cakes taste just as good (if not better) after resting overnight.

They shine in situations like:

• Office morning teas for a medium-sized team.

• Extended family birthday parties where guests may take slices home.

• Dinner parties where the cake doubles as dessert and a talking point.

Our cake size guide shows why this versatile size is the go-to choice for birthdays, dinner parties, and small celebrations.

When you’re hosting a crowd, nothing beats the visual impact and serving capacity of our large cakes for 12+ people. They’re your go-to for:

• Weddings and engagement parties.

• Milestone birthdays with a guest list that just keeps growing.

• School or community events where cake is a major attraction.

A large cake also makes a grand statement on a dessert table, the kind of centrepiece that gets photographed and remembered.

When serving a crowd, our cake size guide recommends this size for maximum impact and generous portions.

When using this cake size guide, it’s important to think about guest count, appetite, and event style before making your choice.

Guest Count and Appetite

Start with your confirmed guest list. Remember that children often eat smaller portions, while adults, especially cake lovers, may go for seconds. If your guest list includes a mix of sweet-toothed friends and lighter eaters, you may find that a medium cake is plenty.

Type of Event

A formal plated dinner often means smaller slices, while a casual buffet can see guests returning for seconds. Think about the setting, will guests be seated and served, or will they be free to cut their own slices?

Other Food Being Served

If your cake is the main dessert, size up. If you’re also serving tarts, brownies, or a dessert platter, you can often choose a smaller size without anyone feeling deprived.

Wanting Leftovers

Some customers specifically order larger cakes so they can enjoy a slice the next morning. If that’s you, consider sizing up for the extra treat.

(Once you’ve settled on size, see our guide on how to choose the perfect cake for your occasion for flavour, style, and decoration tips.)

Even with a cake size guide, it’s easy to make small missteps when ordering:

• Overestimating slice size: If you picture large café-style slices, you might run out early. Our serving sizes are based on standard celebration slices, which are perfect for rich handmade cakes.

• Not considering extra guests: Guests often bring plus-ones or children — a little buffer can save stress.

• Ignoring event style: A formal wedding with plated service requires more precise slicing than a backyard BBQ.

Avoid these common mistakes, and your cake will be the perfect fit for your event.

If you’re torn between two sizes, it’s often safer to go for the larger option. Extra cake can be sliced and packaged for guests to take home, or enjoyed the next day with a cup of tea. Our cakes are rich, so even if slices are slightly smaller, everyone will feel satisfied, and a little leftover cake is never a bad thing.

At Dello Mano, our cakes are more than just beautiful, they’re rich, flavourful, and satisfying in every bite. We bake in small batches using Belgian chocolate, real butter, and premium ingredients, so even a modest slice feels indulgent. This means you can confidently choose a slightly smaller size and still impress your guests, especially when using our cake size guide to select the perfect fit.

We also believe presentation matters, each cake is crafted for beauty as well as taste, so it looks spectacular no matter the size.

Ordering from Dello Mano is simple:

1. Decide how many guests you’re serving- use our cake size guide to help choose.

2. Choose from our small cakes for 4–6 people, cakes for 8–10 people, or large cakes for 12+ people.

3. Add accessories like cake toppers and candles to complete the look.

4. Select your preferred delivery date, we deliver across Brisbane, Gold Coast, and Sunshine Coast.

No matter the size you choose, the magic of a celebration cake lies in its ability to bring people together. At Dello Mano, we believe in creating cakes that are not only delicious but also unforgettable.
