A:Answer Having purchased many refrigerators over the last 30 years and five houses, there is no "standard size" for a fridge. They come in many widths, depths, and heights.
Measure the width of your space, make sure the fridge you're looking at fits in that space. Then measure the height from the floor to any cabinets that are above where your fridge will go.
When dealing with the depth, you have two concerns. One, how far does the fridge stick out past the counters. Most fridges will stick out some. How much space does the fridge need behind the unit, or can you push it flush up against the back wall? If you have an island, or a walk-way, or something else in front of the fridge, when the door is opened fully, will it clear the obstacle in front.
For instance, the doorway to my kitchen is right where the fridge door opens into. I have cabinets opposite the fridge, on the other side of the walkway. When I open my regular single door fridge, the door hits the other cabinets. This fridge, the doors are half as wide (side-by-side), and wouldn't hit (but I didn't buy this fridge in that house).
