Bride wants a wedding cake like this picture. How tall are these tiers? The bottom two look to me like 6" high with possibly a 4" high one on top?

Also, does it look like these are 12", 8" & 6" sized pans or something else?

appreciate your help.

Or, maybe a 5", 6", and 8"... it's hard to tell without knowing how tall they really are in comparison.

I'm thinking they don't look like 6 inch tiers....
Perhaps 4 inches....then a 3 inch on top

What sizes you need depends on how many guests it needs to feed.... i
It would look great in any size tiers.

Yeah that bottom tier definitely isn't 6", I always bake between 5" and 6" tiers, so I think the bottom two are 4" and the top is 3".

I'm with CWR41. Most likely it is an 8,6,5. I had a ruler at my desk and you can get pretty good ratios from that picture. The bottom cake is definitely 2X wider that it is tall.

Also, if the bottom two tiers are 4 inches then the top tier is a weird 3 1/2 inches. Maybe they didn't use a lot of filling or a layer baked up short. That is why the perspective is throwing you off a little.
