Cakes & Frostings 1×2″

Cake Serving & Portion Calculator

Find out how many slices a round, square or sheet cake gives, or which cake (or combination of tiers) feeds your guest list, with wedding, party and generous slice sizes and a cutting guide.

How to use it

Choose whether you want servings for a cake, or a cake for a number of guests.
Pick the shape, size and height, and the slice size you'll cut.
Use the cutting guide for neat, even slices.

How it works

Round and square cakes use Wilton's wedding (1 × 2 in) and party (1½ × 2 in) serving charts for 4-inch-tall cakes, the bakery standard. Sheet cakes are cut in a grid. For a guest count, it searches single cakes, sheets and 2- and 3-tier combinations and lists the closest fits.

Assumptions and limits

Servings assume slices 4 inches tall; tall cakes serve proportionally more and single layers fewer.
Plan extra if cake is the only dessert.

Tips

Cut a 2-inch ring around the outside, slice it, then repeat inward: the Wilton method keeps slices even.
Chill a cake before cutting and wipe the knife between cuts.
For big events, pair a display cake with sheet cakes cut in the kitchen.
