Are there any building standards for sizes of appliance openings between kitchen cabinets?

I am planning to remodel my kitchen and wonder how much openings should I leave for my range and fridge. Currently, it is a very tight fit for my 30" range, but quite generous 38" opening for my 35 3/4" fridge (which actually does not require that much). How much tighter should I go?

So far, most advice that I found says "Check the appliance's owner's manual", and this sure makes sense, however, I don't want to build my kitchen around particular appliance models. I want it to be able to last for decades without me being forced to bear the consequences of my poor decisions.
