Hello everyone!

I am making a wedding cake for a family member who is not picky about shape or size. I am trying to get help identifying the tier sizes (height and width) in the attached pictures. The first picture (pink flowers on top) is classic, but Im pretty sure the tiers are higher than 4 inches and I love the height it has. The second picture (blue flower on side) is more modern and fun, im assuming the bottom tier is 2-3 inches and the top ones are closer to 5-6 inches, but thats just a guess.... 

Any insight would be amazing help and much appreciated!!

Thanks!

The first picture could be a small 8-6-4 with 4" hight. The second one 6 (6" high) - 8 (8" high) - 10 (3"high).
