Planning your dream wedding comes with countless details to consider, and one of the sweetest decisions you’ll make is how much cake to order. While it might seem straightforward, factors like guest count, cake styles, and serving sizes can make this a tricky calculation. Don’t worry—we’re here to simplify the process for you!

How Much Cake to Order for Your Wedding

What you need to know
Step 1: Know Your Guest Count
The number of guests attending your wedding is the most critical factor in determining how much cake you’ll need. As a general rule, plan for:
- One slice per guest for traditional tiered wedding cakes.
- Two to three desserts per guest if you're offering a dessert table or multiple sweet options in addition to the cake.
Be sure to account for RSVPs and factor in a little buffer for last-minute additions.
Step 2: Understand Cake Servings
Wedding cakes are typically designed with specific serving sizes in mind. Here’s a guide to standard servings based on tier sizes:
- 6-inch tier: Serves 10-12 guests (slice dimensions: approximately 1 inch wide by 2 inches long)
- 8-inch tier: Serves 20-24 guests (slice dimensions: approximately 1 inch wide by 2 inches long)
- 10-inch tier: Serves 30-38 guests (slice dimensions: approximately 1 inch wide by 2 inches long)
- 12-inch tier: Serves 45-56 guests (slice dimensions: approximately 1 inch wide by 2 inches long)
For example, a three-tier cake with 6-inch, 8-inch, and 10-inch tiers will generally serve around 75-100 guests, depending on how it’s cut.

Step 3: How to Cut Your Cake for Optimal Servings
Cutting a wedding cake isn’t just about slicing—there’s an art to it! Here’s a simple method to ensure you get the most servings:
- For round cakes: Cut a concentric circle about 2 inches from the edge, then slice the outer ring into 1-inch pieces. Continue cutting smaller concentric circles until you reach the center.
- For square cakes: Slice straight across the cake to create rows, then cut each row into 1-inch pieces.
- Use a sharp knife: Ensure clean, even cuts for better portion control.
- Serve efficiently: Assign a designated server to handle cake cutting to avoid waste or uneven portions.
Step 4: Consider Your Cake Style
Your cake’s design and style can also influence how much you need. Some styles, like taller or more intricately designed cakes, may include extra layers that increase servings. For example, cakes measuring 9+ inches tall can serve twice as many guests if each slice is cut in half. Additionally, if you’re opting for cupcakes, sheet cakes, or additional dessert bars, you might need less of your primary cake.
Step 5: Decide on a Top Tier Tradition
Many couples choose to save the top tier of their wedding cake to enjoy on their first anniversary. If this is a tradition you’d like to follow, make sure to let your baker know so they can account for it in the serving calculation.
Step 6: Don’t Forget Dietary Preferences
Consider the dietary needs of your guests. Offering a gluten-free, vegan, or nut-free cake option ensures everyone can enjoy dessert. In these cases, you may need to order a small, separate cake in addition to the main one.
Step 7: Consult Your Baker
Your baker is an invaluable resource when determining how much cake to order. They can help you:
- Suggest appropriate tier sizes for your guest count.
- Guide you on portion sizes and serving efficiency.
- Provide advice based on their expertise and your specific cake design.
Bonus Tips for Wedding Cake Success
- Order extra cake if you’re unsure. It’s better to have a few slices left over than to run out.
- Plan for photography. Some couples prefer an additional “show cake” to display while serving sheet cakes behind the scenes.
- Think about cake alternatives. If you’re offering a dessert buffet or have a smaller guest list, you can go with a smaller feature cake paired with other treats.
By following these steps, you can ensure you’ll have the perfect amount of cake to satisfy your guests and make your big day even sweeter. Remember, your wedding is a celebration of love—and cake is just the cherry on top!
