Choosing your wedding cake is a big decision. There are so many different designs and shapes you can choose from. Though it can be stressful to know what to get, a wedding cake sizing chart will help.

When deciding on a wedding cake, you want to make sure you choose one that is big enough to feed your guests. After making sure you have the right size, you can choose from different designs and styles. Many different beautiful styles make lovely wedding cakes.

Wedding Cake Size Chart

Most wedding cakes are round and include multiple tiers. Each tier has a cake that typically has between one to four layers. Most standard wedding cakes have between two to four tiers.

Most cake tiers are made up of 6-inch, 8-inch, 10-inch, or 12-inch cakes. On average, wedding cake slices are smaller than normal cake slices. This allows your money to go further when cake shopping.

For wedding servings, a 6-inch cake will serve around 10 people and an 8-inch cake will serve 20-24 people. A 10-inch cake will serve 30-38 and a 12-inch will serve 45-56 guests. This is for average cakes that have three layers per tier.

If you are having a very small wedding, with 30-34 guests, you can serve a cake with a 6-inch tier and an 8-inch tier. For a small wedding, a cake with an 8-inch tier and 10-inch tier will serve around 50-62 guests. For a small to the medium-sized wedding, a cake with a 10-inch tier and a 12-inch tier will serve around 75-94 people.

If your wedding is medium-sized, a three-tier cake with 6-inch, 8-inch, and 10-inch tiers will serve around 60-72. For large weddings, a three-tier cake with 8-inch, 10-inch, and 12-inch tires will serve about 95-118 people. A four-tier cake with 6-inch, 8-inch, 10-inch, and 12-inch tiers will serve between 105-128 people.

Cake Size – Round Number of Servings
6-inch 10
8-inch 20-24
10-inch 30-38
12-inch 45-56


A popular trend now is for people to get a small wedding cake and cupcakes. This is a simple and effective way to serve dessert to your guests at your wedding. It also allows you to get more flavor combinations and can be more budget-friendly.

Most people will get a small two-tier cake or even a one-tier cake to slice. The wedding cake itself will be for the wedding party, with the rest of the guests getting cupcakes. This allows you to order the exact number of cupcakes you’d like.

Sheet Cake

Another common trend is to serve guests sheet cake, while also getting a small one-tier or two-tier cake for the wedding party. This is typically a more affordable option than getting a large cake with multiple tiers.

A half-sheet cake will serve anywhere from 18-40 people, depending on how you slice it. A full-sheet cake will serve anywhere from 48-96 people, depending on how you cut it.

When to Order Your Wedding Cake

To ensure you get the cake and design you want for your wedding, you should find a baker six months to a year before your wedding date. You will want to meet with the baker to discuss cake flavors, design, and servings.

The baker can help you decide the best size of cake to get based on how many guests you plan to have. About a month before your wedding, you will give your baker the number of guests that will be attending your wedding. This will ensure that the cake they make you will have enough servings.

Another thing to take into consideration when ordering a cake is if you want to save the top tier. Many couples choose to save the top tier and freeze it so they can eat it on their first wedding anniversary. If you choose to do this, make sure you still have plenty of cake for all your guests to enjoy.

What Size Cake Stand for a Wedding Cake?

The exact size of the cake stands you need for a wedding cake will vary depending on what size your wedding cake is. It is important to always choose a cake stand that is larger than the cake you are serving.

The cake stand you choose should be at least two inches in diameter larger than your wedding cake. It is alright to go larger than two inches but you do not want to go any smaller. For example, if you have a 10-inch wedding cake you will want a cake stand that is at least 12 inches in diameter. 

What Size Wedding Cake Will Feed 150 Guests?

To serve 150 guests, your best bet is to go for a five-tier cake.  For the tiers, you will want a four-inch, six-inch, eight-inch, 10-inch, and 12-inch cake. 

A four-inch cake will serve six people, a six-inch cake will serve 14 people, an eight-inch cake will serve 28 people, a 10-inch cake will serve 38 people, and a 12-inch cake will serve 64 people. Together, this equals 150 servings of wedding cake. Traditionally, wedding cake slices are smaller in size than the cake slice sizes you would serve at a party.

What Size Plate for a Wedding Cake?

The exact size plate you will need for a wedding cake will vary by the size of your wedding cake. Ideally, the plate should be at least two inches bigger than the size of your wedding cake. So, if your wedding cake is 12 inches in diameter, you will want a plate that is at least 14 inches in diameter.

Be sure to choose a sturdy plate that will sit flat on the table. You don’t what the cake to sit unevenly and potentially cause it to tumble over. 

How Many Servings are in a 4-Tier Wedding Cake?

A four-tier wedding cake will typically serve 75 people. Traditionally, a four-tier wedding cake will have a four-inch cake, a six-inch cake, an eight-inch cake, and a 1o-inch cake. 

A four-inch cake will serve six people, a six-inch cake will serve 14 people, an eight-inch cake will serve 28 people and a 10-inch cake will serve 36 people. This will serve up to 84 people, giving you the option to have a few slices left over, which is always recommended when it comes to wedding cakes.

In addition, you can also cut the slices slightly larger as well. Wedding cake slices are cut smaller than cake slices you would serve at a birthday party or small celebration. 

How Many People Does a 2-Tier Wedding Cake Serve?

The number of people a two-tier cake serves will vary by the size of your two cakes. Most bakeries will sell a variety of options for two-tier cakes. You can get a four-inch with a six-inch, a six-inch with an eight-inch, an eight-inch with a ten-inch, and a ten-inch with a 12-inch cake.

A four-inch cake and a six-inch cake will serve 20 people and a six-inch with an eight-inch cake will feed 42 people. An eight-inch cake with a ten-inch cake will serve 64 people and a ten-inch cake with a 12-inch cake will serve 86 people.

How Many Does a 14-Inch Round Wedding Cake Serve?

A 14-inch round cake can serve up to 78 people when cut into wedding cake slices. Wedding cake slices are smaller and are generally one inch by one inch.  When it comes to party servings, a 14-inch round cake can serve up to 63 people.

Making Sure to Use a Wedding Cake Serving Size Chart

Before you decide on a cake, be sure to use a wedding cake sizing chart. This will help you determine what size cake you will need to get. After you know what size to get you can decide on flavors and design.

In addition, you will also want to tell whoever is in charge of serving the cake what size slices to cut. This will ensure that there will be enough cake for everyone at the wedding to have. Since wedding cake slices are smaller than standard, it is essential whoever is in charge knows this.
