The main objective of this guide is to provide guidance on how thick a floating shelf should be. This will allow the shelf to float in a manner that does not cause the weight of the contents to put undue stress on the anchoring points. If a floating shelf is not installed properly, it can cause damage to your home and property.
The professionals have all agreed that if you have installed your floating shelves correctly, they should be installed as follows:
● 0.125 inch (3mm) - For a standard length shelf: Use 1/4 inch (6mm) lumber or equivalent material thicknesses.
● 0.25 inch (6mm) - For a standard width shelf: Use 1/2 inch (12mm) lumber or equivalent material thicknesses.
