So I need some advice. I always seem to have the challenge of determining sizes for stacked birthday cakes because people never know how many people they want to feed from their cake. Most times it seems they are planning the cake before they make their guest list. Do you think a 6" and a 9" round look better stacked or a 6" and a 10" round? The design is a paisley cake on top (link below) and an East Indian themed cake as the bottom cake (photo attached)

Personally I choose the 6,9 combination.
Then again, if you off set the 6 - rather than center it - it can look good too depending on the design.
Here are a couple examples of the two different sizes. Maybe you can tell the difference; if not then go w/the size that give you the # of servings you need

Personally I prefer the 6" and 9" but it's going to depend on what you find most pleasing and the number of servings you need.

Saw the photos and I agree with both of yall. The 6" and 9" looks better. Thanks again.
