Frequently Asked Questions
How many servings does a wedding cake slice provide?
Standard wedding catering slices are cut about 1 inch by 2 inches, much smaller than a typical dessert slice, which is how bakeries get more servings per cake.
How much buffer should I add for cake servings?
Most planners recommend a 10-15% buffer above your guest count to account for extra staff, vendors, or guests wanting seconds.
Do all tiers need to be the same serving size?
No, tiers are often different sizes. This calculator gives you an average per-tier estimate — your baker can help distribute servings unevenly across tiers for the best visual effect.
