I'm kind of assuming that you are wanting to go with party servings, but I could be completely wrong. Anyway, you could go with a 12" and 14" (party sizes serve 111).
Or you could go with wedding sizes. If you did a 6, 8, and a 10 that would give you exactly 100 slices. (18, 32, and 50 slices).
Party sizes again, if you want 3 tiers, you could do a 8, 10, and 12. (20, 30, 48 slices) would give you 98 slices.
Here are some links for both Wilton's Party Serving Guide and the Wedding Serving Guides depending on the size of your pans. Party Serving sizes are 1.5X2Xheight while the Wedding sizes are 1X2xheight
Party Serving Guide for 2" and 3" pans
Wedding Serving Guide for 2" and 3" pans:
Here's a link to IndyDebi's how to cut the cake that shows a picture of a wedding serving size:
If you want a two tier wedding serving size cake in square I would go with a 8/12 combo as that would give you a 104 servings.
For a two tier party serving size cake in square it would be a 12/14 yielding 111 servings as clystrial mentioned.
Hope that helps!
Thank you for all the help,I'm ver new @ this.Do I do a 2 layers or 3 layers per tier?I'm not really sure how to do it.And another question is party cake different from a wedding cake just by the way they are cut?I guess I don't know if I want a party serving or a wedding serving b/c I don't know the diffrent in the two.Thanks again.
The usual size for each tier is 4". You could make 2 layers for each tier with one layer of filling between them or you could make 3 layers and have 2 fillings between them it all depends on the size of your layers. I usually just make 2-2" layers because I haven't gotten around to buying a good leveler yet (aka agbay ). Yes the only difference btwn the party and wedding cakes is the size of each serving. Party size is larger than a wedding size. If you look at the link I attached of Indydebi's you can see what a 1X2X4 serving size looks like.
Hope that makes sense. If it doesn't let me know.
Thnks that helped alot.Now I understand better between party serving & wedding & the hight of the cake.
Glad I could help.
