Wedding Cake Sizing Guide
Getting the right amount of cake is all about matching servings to your guest count. A standard wedding cake serving is a 1x2x4 inch slice. Each round tier yields a predictable number of servings based on its diameter.
For most weddings, a 3-tier cake covers 60 to 100 guests. If you have more than 150 guests, consider the sheet cake hack: use a stunning 2-tier display cake for photos and the cutting ceremony, then serve additional slices from sheet cakes prepared in the kitchen.
- •6-inch tier: 12 servings
- •8-inch tier: 24 servings
- •10-inch tier: 38 servings
- •12-inch tier: 56 servings
- •14-inch tier: 78 servings
- •16-inch tier: 100 servings
Wedding Cake Costs Explained
Wedding cake pricing depends on four main factors: the number of servings, the type of frosting or covering, the complexity of the design, and your baker's experience level. Buttercream cakes are the most affordable at $3 to $5 per slice, while elaborately designed fondant cakes can reach $10 to $15 per slice.
Fresh flowers on a cake are significantly cheaper than handmade sugar flowers. A simple cake with fresh blooms can look just as stunning as an elaborate fondant creation at a fraction of the cost.
Popular Alternatives to Traditional Wedding Cake
Not every couple wants a traditional tiered cake. Dessert tables, cupcake towers, donut walls, and pie bars have become increasingly popular alternatives. These options often cost less per serving and give guests more variety.
- •Cupcake tower: $2 to $4 per cupcake, no cutting fee
- •Dessert table: $8 to $15 per guest for variety
- •Donut wall: $1 to $3 per donut, very Instagram-worthy
- •Pie bar: $3 to $5 per slice, great for rustic themes
- •Ice cream bar: $4 to $8 per guest, perfect for summer
Wedding Cake FAQ
Everything you need to know about our free tools and how they help your wedding day.
For 100 guests, a 3-tier cake (typically 6, 9, and 12 inch tiers) provides about 100 servings. This is the most popular configuration for mid-size weddings.
Wedding cake costs $3 to $15 per slice depending on the type. Buttercream is $3 to $5, fondant is $6 to $9, and elaborate custom designs can reach $10 to $15 per slice.
Order a small, beautiful display cake (1 or 2 tiers) for photos and the cutting ceremony. Then serve guests from plain sheet cakes prepared in the kitchen. Guests get the same cake flavor, you get stunning photos, and you save hundreds of dollars.
Book your cake baker 4 to 6 months before the wedding. Popular bakers can be booked up a year in advance, especially for peak wedding season (May through October).
Many venues charge $1 to $3 per slice as a cake cutting fee if you bring in an outside cake. Ask your venue about this fee before ordering, as it can add $100 to $300 to your total.
You can, but it is a significant undertaking. A homemade cake works best for small weddings under 50 guests. For larger weddings, the logistics of transport, assembly, and temperature control make professional bakers worth the investment.
Most bakers prepare cakes 1 to 3 days before the wedding. Fondant cakes can be made slightly earlier as fondant preserves moisture. Buttercream cakes are typically made the day before.
The most popular wedding cake flavors are vanilla, chocolate, red velvet, lemon, and carrot cake. Many couples choose different flavors for each tier so guests have options.
