How should I measure my space before installing the RF28JBEDBSR?

Measure the height, width, and depth of the opening, making sure to include baseboards, molding, tile, countertop overhang, and any other obstacles. You should also ensure that each door and entryway in the home is wide enough for the refrigerator to be moved through easily, and check that there is enough room to fully open the refrigerator doors.
