What Size Auger For 4 Inch Post

Post Holes- For example: A 4×4 post (actual size 3.5″x3. 5″) has a maximum width of just over 5″ (diagonally). Therefore, the 4×4 post will likely fit into a hole drilled by a 6″ diameter auger.

What size hole should I drill for a 4×4 post?

A general rule of thumb is to dig the diameter of the hole at least 3-4 times the diameter of the post. For example, if setting 4 x 4 wood posts, dig holes 9-12″ in diameter. Posts should be centered in the hole and the posts should always have concrete under them.

What size auger do I need for fence posts?

A 12-inch auger, best attached to a heavy machine, will create a hole large enough for a 6×6 or 4×6 post and plenty of concrete. Smaller augers, like 4- or 6-inch options, are appropriate for light-duty work (like mailboxes) as well as metal fence posts for chain-link fences.

What size auger should I buy?

How far apart should fence posts be?

Most fence posts can be spaced 8 to 12 feet apart. While this is a general criteria, it doesn’t cover all scenarios.

How do you measure auger diameter?

How many fence posts do I need for 1 acre?

If we assume that your property is equal on 4 sides, then it is as simple as taking the square root of 43,560 square feet. This gives you 209 feet on each side, which would require 835 linear feet of fence to enclose the entire acre property (209 feet times four sides is equal to 835 linear feet).

How far apart should 4×4 fence posts be?

Too far apart and the strength of your fence is compromised; too close and your fence may look strange. For most privacy and general-purpose fences, 6 or 8 feet between posts is standard.
