There are a wide range of refrigerator styles, and variation of dimensions within those styles. "Standard" can thus mean many different things. Also you need to be aware that the size of the fridge doesn't necessarily equate to the size of the opening in your cabinets either. You need to leave adequate clearance both for cooling purposes and to allow for clearance for the doors to open in some cases.
The posted ranges here are ok, but you will find that fridges over 70 inches are becoming more common. For instance, Whirlpool's new fridges are 70 inches tall, and need over 71 inches to allow for clearances. Sub-zero's lineup is significantly taller than that.
Given the wide range of fridge sizes, it's advisable that you pick out the fridge you want, and use it's specific dimensions for planning purposes. There's just too much variation otherwise.
You can find the dimensions of various refrigerators at their manufacturer's websites. Remember to look up the clearance necessary as well, to get an accurate measure of how much room you need for the specific fridge. There is a site, http://fridgesizes.com that does a lot of this leg work for you, and can be helpful if you need to find a fridge to fit in a specific dimension.
