You’ll also find design ideas, flavor tips and ordering guidance, so you can team up with the Strack & Van Til bakery near you to create a cake your guests will love.

What size graduation cake do you need?

A quarter sheet serves about 20–25, a half sheet serves about 40–50 and a full sheet serves about 80–100 guests. These serving ranges follow standard bakery sizing and match what families order during graduation season.

How many people does each sheet cake size serve?

A quarter sheet feeds small gatherings, a half sheet fits medium parties and a full sheet works for large open houses. Strack & Van Til Bakery Director Stephanie Flynn confirms that these serving counts reflect what customers choose most often.

What cake size should you order for your guest count?

Choose a quarter sheet for 25 guests, a half sheet for 50 guests and a full sheet for 100 guests. These sizes give you predictable servings and enough cake for guests who come and go.

25 guests

A quarter sheet is the right fit for small graduation parties or family gatherings.

50 guests

A half sheet gives you enough for generous slices or a little extra.

100 guests

A full sheet is the best choice, or pair a half sheet with cupcakes, cookies or cake pops.

What are the dimensions of quarter, half and full sheet cakes?

A quarter sheet is about 9×13 inches, a half sheet is about 12×18 inches and a full sheet is about 18×24 inches. These sizes follow standard bakery proportions and help you plan for serving counts and table space.

How far in advance should you order a graduation cake?

Order at least 48 hours in advance, and earlier for photo cakes or detailed designs. Graduation season fills up quickly.

“If you’re ordering a custom cake, place your order no less than 48 hours ahead of time. Order even earlier if you want photo cakes, edible images, school colors or more detailed personalization,” Flynn advises.

Are sheet cakes or round cakes better for graduation parties?

Sheet cakes are the better choice for graduation parties because they serve more people and are easier to cut. Round cakes work well for smaller celebrations, but sheet cakes offer predictable servings and a large surface for photos and messages.

“While our Bakery Department’s round cakes are a Northwest Indiana favorite, they’re really better for smaller gatherings. Sheet cakes are the way to go when you’re serving a crowd at graduation or any other large party,” Flynn explains.

Does cake height affect serving count?

Cake height can shift servings slightly, but the cutting method matters more. Taller or layered cakes may stretch servings if you cut smaller pieces.

What Is the Best Way to Cut a Sheet Cake

Use the grid method — even rows and columns — to get consistent servings. This keeps your serving count predictable and makes cutting fast and clean.

A few quick tips:

· Use a long sharp knife

· Wipe the blade between cuts

· Lightly score the grid before slicing

· Aim for 2×2 inch pieces for large groups

What graduation cake designs can you order?

Strack & Van Til offers school colors, edible images, themed decorations and coordinating desserts. Your cake can match the graduate’s school, personality or party theme.

Options include:

· School colors or themed borders

· Graduate’s name, class year or monogram

· Edible images or photo cakes

· Graduation cap, diploma or themed decorations

· Coordinating cupcakes, cookies or cake pops

What cake flavors work best for summer graduation parties?

Buttercream cakes hold up best in warm weather, while whipped cream cakes need refrigeration. Outdoor parties and Midwest humidity can affect your cake choice.

Flynn recommends buttercream for warm-weather events. “Whipped cream cakes aren’t suited for the outdoors in our humid Northwest Indiana summers.”

Strack & Van Til offers scratch-made flavors including chocolate, yellow, white, banana, red velvet, Oreo cookies and cream and the signature Atomic Cake.
