The dimensions of my custom shelf were 60″ in height and 28 1/2 ” in width. The depth was 11.5″. To make my side panels and my top and bottom I had to use 4 of the 2.5″ (width) wood boards and 1 of the 1.5″ inches in width to equal a total of 11.25″. If your confused take a look at the video of how I made the panels.
