33" or 36" for fridge??

Doing a budget kitchen reno for my wife and a new fridge has to wait a bit, but lots of other work going on.

I took down a load bearing wall, relocated lots of electrical and plumbing, and moved the sink location from the corner with its adjoining DW and put in an IKEA Domsjo farm sink with the DW in front of the open pony wall where the full wall was.

I have a 24" cab to plug in where the DW was and a new corner cab with lazy susan to plug where the corner sink was (we hated that corner sink!).

The existing corner sink had a spacer between it and the DW. The current over/under fridge is 33". I'm thinking when I pull the old sink/corner cab out this weekend that I should slide the cabs down 3" so that I have a 36" gap where the fridge is now and put a filler in next ot the existing fridge for the present time. I'd have to slide two uppers, shorten my countertop measurement by 3",and plan for 3" more flooring under the fridge to provide for this extra width for a new fridge at a later date.

Looking at fridges, it looks like 36" might be a more common width. Thoughts??
