Wedding Cake Sizes: How Much Cake Do You Need?

The biggest mistake couples make with wedding cake is over-ordering. Cake sizing is confusing — the same cake can serve 60 or 150 depending on how it is cut.

The two portion sizes that matter

• Dessert portion: 1 inch by 2 inches — if cake is served as dessert
• Finger portion: 1 inch by 1 inch — with coffee or in evening hand-out

The same 8-inch round cake serves 24 dessert portions OR 50 finger portions.

How to size by guest count

Most weddings serve cake as evening food (finger portion sizing):

• 50 guests: Single 8-inch tier, or 6-inch + 8-inch
• 80 guests: 6-inch + 8-inch + 10-inch (3 tiers)
• 100 guests: 6-inch + 8-inch + 10-inch
• 120 guests: 6-inch + 8-inch + 10-inch + 12-inch (4 tiers)
• 150 guests: 4 tiers, larger sizes
• 200 guests: Multiple cakes or a 5-tier

The display cake + sheet cake trick

Want a beautiful 4-tier without paying to feed 150? Order a smaller display cake (your 3-tier showpiece) plus a plain sheet cake hidden in the kitchen. Caterers cut and serve from the sheet cake — guests cannot tell the difference. Saves £200-£400.

Timing

Book your cake maker 6-8 months before the wedding. Confirm final design 4-6 weeks before. Most makers deliver and assemble at the venue.
