If you are going to measure whether the wall changing table fits in the place you have in mind, keep the width and height of the changing table. This space occupies the changing table on the wall. The depth measure is the space that the changing table occupies in the area of floor space or room space. There should be enough space in the room to open and close the changing table. Keep the maximum depth measure and still count space for yourself and your child. This is the depth measure that is included in the "open" sizes.
