Granite is one of the best natural stone options you have for kitchen countertops, bathroom countertops, backsplashes and other home surfaces. The stone is well known and beloved for being attractive, durable and easy to take care of. Granite countertops have seen a significant climb in popularity since the early 1990s, when the stone became more affordable due to an uptick in supply worldwide. This guide will give you information about the weight of granite. 


Thickness of Granite 


The weight of a granite slab will depend on the thickness. Most granite slabs are either ¾ of an inch thick or 1 ¼ inches thick. Slabs can be thicker, but slabs that are thicker than standard are very rare and are more expensive.
