Each cake tier is on average 5″ tall.
A standard wedding cake portion is 1″ x 1″. This is normally a sufficient portion size for your guests.
However, if you would like your wedding cake to double as a dessert or just like larger portions I would suggest a 1″ x 2″ portion or bigger.
The larger the portions needed, the bigger the cake / the more cake tiers needed.
Here are a few examples of portions (based on 1″ x 1″ portions):
|3-tier (8″/6″/4″)||3-tier (9″/7″/5″)|

|Feeds 165 people||Feeds 210 people|
|5-tier (11″/9″/7″/5″/3″)||5-tier (12″/10″/8″/6″/4″)|
|Feeds 170 people||Feeds 220 people|
