Drawers down low are for long term storage, so any large number of inches will do.
Drawers closest to the counter are 3" deep. Cutlery, spatulas, whisks.

HAve any number of drawers of any other height.

I measured all my stuff. My tall canisters, stockpot and some other things are 11" tall, so my bottom drawer has 11" interior (13" exterior), my next size canisters are almost 9" and a lot of my pots are 8", so my next drawer is 9" (11" exterior). That left 4" interior (6" exterior) for the utensils. This worked well enough that I did the entire perimeter in those heights, for the looks. These heights work fine as well for my bakeware, containers, tea towels and flatware. For the island, I just followed the line of my fridge drawers, which are a little deeper on the bottom, but more or less have two evenish drawers on one side (mixing bowls and colanders) and four evenish drawers on the other (knives, wraps, gadgets, tools).

I think fitting the staples (flour, sugar, etc.) in my corner drawers was the most specific thing I wanted. I could have dislocated the stockpot.

Your measuring tape is your friend! Good ol' Stanley. :)
