You’re baking or buying a cake for a party, but how much cake do you need in order to feed everyone? I’ve compiled a list of common cake sizes and the average number of servings. Whether planning a family dinner or a wedding this guide can help you with all your party planning needs!

Sheet Cake Serving Size Guide
| #of servings | # of servings | # of servings | |
| Size | 1×2″ pieces (small) | 2×2″ pieces (medium) | 2×3″ pieces (large) |
| 9x13x2 (quarter sheet) | 54 | 24 | 18 |
| 12x18x2 (half sheet) | 108 | 54 | 36 |
| 16x24x2 (full sheet) | 192 | 96 | 64 |
Obviously, this is just a serving size guide. If you have a taller cake, such as a 3 layer 9″ cake you may be able to cut the cake into smaller pieces. For a tiered cake you can add the number of servings for the size of each layer to get the total number of servings. For example if you have a round three-tiered wedding cake with an 8″, 6″, and 4″ tier you will have about 24 servings.
