What Size 30th Birthday Cake Do You Need?

The right cake size depends on your guest count and how you plan to serve it. For an intimate dinner of 10 to 15 guests, a 7 inch round cake offers generous portions. For parties of 20 to 30 guests, a 9 inch cake is ideal. Bigger celebrations with 40 to 60 guests call for a two tier design or a 10 to 12 inch single tier. Take a look at our cake portion guide for a full breakdown of sizes and servings.

Hosting a major 30th celebration with 60+ guests? Paulina can create a stunning multi tier centrepiece or combine a decorative display cake with a larger cutting cake to make sure there is plenty for everyone.

Customisation Options

Your 30th birthday cake is designed entirely around you. Choose your colour palette, your finish (explore the differences between buttercream and fondant), your flavour combination and your decorations. From edible gold leaf and metallic drips to hand painted details, sugar flowers, personalised name plaques and acrylic toppers, every element is crafted to your brief.

Paulina loves working with inspiration images. If you have seen a cake on social media that captures the look you want, share it and she will create her own bespoke version tailored to your celebration.
