3/16", 1/4", 3/8", and 1/2" are usually used for shelving. 1/4" and 3/8" are by far the two most popular shelf thicknesses we sell. 1/4" shelving is usually used for economy, since thicker glass is more expensive. 3/8" is usually used for high-end applications and can really make a stunning difference. Other than cost and aesthetics, thicker glass can also support more weight.Click here to view images of different thicknesses
Weight to be Supported by the Glass Shelf
The amount of weight the glass will support depends on the thickness of the glass, the square footage of the glass, and the span between supports.
Maximum permissible load for glass shelf:
This calculator is based upon tests for annealed float glass only. The maximum permissible load is the weight in pounds in which tests resulted in 3 broken shelves in 1,000. Use this only as an approximation, and only when your span between supports is close to the available options. It is also best to use the largest span that is closest to your actual span. For instance, if you have a 20" span then use the "2 feet" span. Any weight a 2 foot span will support, a 20" span will also support.
