Tri-State Stone Name and Sizing Chart
Belmont Mills is located in Eastern Ohio and we have a number of contractors from Pennsylvania and West Virginia that we service. Because of this, there is often confusion on what size stone a contractor may actually want. This chart provides the common terminology for each state along with the actual size of the stone each name represents.
If you need material delivered to your job site reach out to our logistics department with any questions.
