help pls experts

i have got an order to make 4 tired birthday cake 

 

what measurements are used in this size of cake

AHi there, without a point if reference it's hard to say exactly but it looks like there is about an inch around the edge of each tier on the top one so say a 6", 8", 10", 12" and maybe an inch and a half around the one below. That said, the tiers on the second one aren't as tall so it could be a bit of an optical illusion so could still be an inch. It's funny, my first wedding cake was for a friend and she showed me that top picture as her inspiration! I used those proportions and the tall tiers and one thing I can say is that it is a LOT of cake. Have fun!

AAs snowflakebunny stared, those are 2 different sized cakes.

The smallest 4 tier I offer is the 6,8,10,12. Some offer a 4,6,8,10.

AThanks i am a bit scared as to how will i manage to put up a perfect four tired cake any further u can help
