When Building a drystone wall, one ton of stone will create around 15 cubic feet of wall ( 1' high x 1' wide x 15' long). Calculate the total length of your wall, and then use the following formula:

4" Veneer = 40-45 Sq.Ft./Ton

6" Veneer = 30-35 Sq.Ft./Ton

8" Veneer = 25 Sq.Ft./Ton

3"-6" Veneer = 35 Sq.Ft./Ton

3"-5" Veneer = 40 Sq.Ft./Ton

4"-8" Veneer = 30 Sq.Ft./Ton

All coverages are approximate.
