What size opening should be left for a refrigerator?

Typically when building a home without a specific model of refrigerator determined in advance, the refrigerator is assumed to be 36" wide by 69" tall. Because of differences in floor heights, refrigerator hinge heights and cabinet door swings (cabinet doors above the refrigerator can bump into refrigerator top mount hinges), add an inch or two to the height of the opening. A safe opening size would be 36.5"-37" wide and 70"-71" tall.
