you know how to use a tape measure. the inside width will tell you how much you can put into it. that is the most practical thing to know. the shortest dimension. maybe "she" will get this measurement for you over the phone. -- you know how to multiply. h times w times depth inside dimensions = this will give you the volume in cubic inches. divide by 1720 to get cubic feet in real terms. any company is allowed to state any number as nominal cubic feet without regard to reality. real cubic feet is always good to know. then, the other good to know is whether or not anything you need to put into it is going to fit well with the shortest dimension. -- a cube holds more, has more real volume, than a long thin space. --

I just bought and installed the KitchenAid counter depth french door fridge. Not the supersized one. I chose it for a couple of reasons bur primarily because it was one of the few I could get without a water dispenser in the front door (though there is a discreet one inside the fridge). I hated the fact that the counter depth added about a $1000 to the price tag and worried that I would not feel the aesthetic advantage justified that price difference once I got it since I was trying to be very frugal in my purchases. I was so wrong. I am crazy about this fridge. The bottom freezer holds everything my old full depth freezer did except I can see it all so easy in the lighted space with 3 slide out layers. I can see everything I have when I open the french doors. Nothing hard to get at. Nothing out of sight. The door shelves hold tons of stuff too. I like that the sides are gray....not black...so if some of the side had to show it would blend fairly well with the stainless. Mine will not show as there will be a full panel of cabinet wood covering both sides (cabinets arrive in 2 wks). I'm having an open shelf/cubby above it to hold cookbooks. Buy this unit with confidence.

I'm somewhat confused by your terminology. Typically a "wine fridge" is designed to keep red wine at ideal serving temps--somewhere between 55 and 60 degrees. Certainly some also are dual zone and thus can also cool white wine to a lower temp, usually in the mid-40's. This is different than a wine storage cellar or cabinet, designed to allow wine to age properly over long periods of time. They are usually run in the 55-60 range, for reds and whites alike. This contrasts to what you'd want for pop, water, juice etc--there you'd want typical refrigerator temps, more like 35-37 degrees. That is too cold to server any kind of decent white, though certainly some folks like whites that cold. So first job would be to decide what you're looking for.
