How Deep Should a Chain Link Fence Post Be?
Approximately 3 Feet
Wuzhou Kingda recommends digging a hole at least 30 inches deep for residential chain link fence posts. The proper depth is 30 inches to 36 inches, as long as it reaches below the frost line level for the area.
It Depends
"Depending on the geographical location, fence height, and fencing materials used, post hole size may vary," says the Hoover Fence Co. A rule of thumb it recommends is to dig the hole to a depth one-third of the height of the fence that's above ground, so that a 12-foot-high fence requires a 4-foot hole. Typically, a chain link fence with a gate requires even deeper post holes to withstand the additional stress of a moving gate, advises Hoover Fence.
Bottom Line
Consider several factors to determine the depth of a post hole, such as the frost line of your geographical area, gate use and the overall fence size. In general, the deeper the hole, the better, as it will allow the chain link fence to withstand more movement due to climbing, climactic elements or a swinging gate.
