Crushed Stone #1: Approx. 2″-4″ Wide. Crushed stone grade no. 1 is the largest size with diameters ranging from around 2 inches to 4 inches. As this grade contains larger pieces, it’s not suitable for shoveling and stones will need to be moved individually. Typical uses for gravel #1 include: Filling larger holes.
