I always start with the top tier as reference cos even if u go up one size or down it will still be ur constant guide. Looking at the photo it looks like the height is constant at 4 inches.
So your top can be 6 × 4
Then 8 × 4
Then 10 × 4
If u want a bigger cake then…
You can also start at 8” in diameter but you would need to add one inch to the height so that it wouldnt look too wide and flat at 8 x5, 10 x5, 12 x5.
You can look to the sides and see if the space is even all thru out the layers. If it appears narrower then the increment could change to one inch, and if wider, the increment could change to 3 or 4 inches, but usual increments are by 2s.
My students always ask me about my dimensions cos my cakes are usually taller and slimmer. And my increments are never the same. Its tricky but the cakes come out very modern and photogenic.
