I often struggle with estimating how many people a sheet cake can feed, especially when portion sizes vary for different events. A casual party might have larger slices, while a wedding or corporate event might go for smaller portions to serve more guests.

From what I’ve learned:

A full sheet cake (18” x 24”) can serve 48 to 96 people, depending on slice size.
A half sheet cake (12” x 18”) serves around 24 to 48 people.
A quarter sheet cake (9” x 12”) typically serves 12 to 24 people.
I found this guide www.customcakeboxes.com/people-sheet-cake-feed/ really helpful—it breaks down sheet cake sizes, portioning styles (party vs. wedding servings), and even tips on maximizing servings. It also covers things like frosting thickness and layering, which can affect how easy it is to cut uniform slices.

For those who bake or order cakes often, how do you estimate servings? Do you stick to a standard portion size, or do you adjust based on the event? Any tips for making sure there’s enough cake without too much waste?

Looking forward to your thoughts!
