I did some research and I think I got this right please correct me if I'm wrong.
for an all square cake tiered cake for 100 ppl
12" bottom cake 60 servings
10" middle cake 40 servings
8" top cake 24 servings
It depends on the size servings you want. If you serve the typical wedding size of 1x2x4 then a 12" would serve 72, 10" = 50, 8" = 32. HTH
Most wedding servings are 1" x 2" x 4". In this case the amounts would be:
12"- 72 servings
10"- 50 servings
8"- 32 servings
You could try:
That would make exactly 100 servings. HTH!
here is the guide I go by
Its also the chart that Cake Boss uses (calculating software)
It looks like you used the same chart and came up with the same amount. If you switched out the 8" for the 6" it would give you 112 servings
So youre on the right track
I use wilton's wedding chart for a number of reasons.
1) 1x2x4 is the industry standard size serving for a wedding.
2) Most venues cut 1x2x4 pieces.
3) you get more money for the cake when using this chart.
4) they are welcome to cut it any size they want, but they are PAYING for the number of (wilton wedding cake) servings the cake is DESIGNED to serve.
5) You get more money for the cake when using this chart.
6) If you plan large sizes of cake, and the venue cuts in 1x2x4 standard servings, the bride ends up with a lot of leftover cake. When brides see a lot of leftover cake, they have buyer's remorse because they THINK they bought too much cake ... not knowing the cake maker just made too much cake. Post-Wedding-Bridezilla may kick in as she tries to find some reason to get a refund because she think she spent too much money.
7) Did I mention you get more money for the cake?
