Wedding Cake Portions Guide
I get asked this all the time: how many portions do I actually need? It's one of the trickiest bits of planning a wedding cake, so here's everything you need to work it out, in plain English.
Finger portions vs dessert portions
The slice size makes a big difference to how many portions your cake gives, and there are two main ways to serve it.
A finger portion is the traditional wedding size, 1" x 1" x the height of the tier. It's perfect after a three-course meal with coffee, when people want a taste rather than a full pudding.
A dessert portion is more generous, 2" x 1" x the height of the tier. This is the one to go for if your cake is being served as the actual dessert.
Tier heights
Cake height matters too, because a taller tier gives more portions. I usually offer two.
A classic rise is 4" tall, two layers of cake with one layer of filling. A tall rise is 6" tall, three layers of cake with two fillings, so you get noticeably more from the same size tier.
Work out your cake
Rather than doing the maths yourself, use the calculator below. Pop in your guest number, choose your slice size and tier height, and it'll suggest a cake that fits, with the full portions chart there too if you'd like to see the detail.

I'm Floriana, and I've been designing bespoke wedding cakes since 2010.
My style is romantic but relaxed. Soft buttercream, delicate florals, and details that feel like you, not a copy of someone else's Pinterest board. Every cake is designed around you and your day, and I deliver each one myself so it arrives exactly as it should.
