Joe,
The front is shorter than the sides and backs to allow items to be place on it easier and provide support in the back. At the front it is 3″. The side has has a roman ogee profile curving up to the side height of 8″; the back is 8″.
I do no know how to add the image or file to this forum so I sent it to you in an email.
Thank you for the settings image.
Lynn
