30 Inches Deep
-
Dig post holes at least 30 inches deep. When installing chain link fencing, set the posts at a depth of 30 inches or at least as deep as the frost line in the area where you reside. This will prevent posts from rising out of the ground if the ground freezes below the post end.

18-Inch Minimum Depth
-
Holes should be a minimum of 18 inches deep. When erecting a chain link fence, you may run into obstacles that prevent you from digging to the desired depth. Rocks or other hard surfaces can make it impossible to set posts 30 inches deep. According to the Hoover Fence Company, belling the hole, or making it at least 2 inches wider at the bottom than it is at the top can compensate for holes as shallow as 18 inches.
Bottom Line
-
When installing a chain link fence, bell holes that are between 18 and 29 inches deep. While digging post holes to a depth below the frost line is the best option to ensure protection from the elements, if necessary, you can bell holes that are between 18 and 29 inches deep.
