How Many Fence Posts for a 200 ft Picket (4 ft Wood) Fence?

A 200 ft 4 ft wood picket fence needs 26 posts at 8 ft spacing. That's 25 panels plus one post at each end. Add 2 extra posts for each gate opening.

Installed cost for a 200 ft 4 ft wood picket fence typically runs $2,400–$4,000 depending on your region, labor rates, and ground conditions. Materials alone are usually 40–50% of the installed price. DIY installation can cut costs significantly, especially for chain link and split rail.

At one 50-lb bag per post, a 200 ft 4 ft wood picket fence needs 26 bags of concrete. Corner posts and gate posts may benefit from a second bag each for extra stability. Fast-setting concrete (such as Quikrete Fast-Set) can be poured dry and sets in 20–40 minutes.

The standard rule is to bury one-third of the post's total length, with a minimum of 2 feet below grade. For a 6 ft fence use 8 ft posts set 2 ft deep; for a 4 ft fence use 6 ft posts set 2 ft deep. In cold climates, posts must extend below the frost line — check your local frost depth, which can reach 5 ft or more in the upper Midwest.

One 50-lb bag of concrete per standard 4×4 post is a common quick-set guideline for residential fence posts set in a 10-inch diameter hole at 2 ft depth. For corner posts, gate posts, or posts in loose or sandy soil, use a second bag for extra stability. Quikrete Fast-Setting Concrete requires no mixing — pour it dry into the hole and add water.

8 ft spacing is the industry standard for most wood, vinyl, and split rail fencing. 10 ft spacing is typical for chain link because the wire mesh spans wider gaps without sagging. Tighter spacing (6 ft) adds strength for high-wind areas or heavy gates but increases post and concrete costs.

Yes — each gate opening requires two extra posts (one on each side). The gate itself does not count as a fence panel. Add 2 posts and 2 bags of concrete for every gate you plan to install on top of the counts shown on this page.

Most municipalities require a permit for fences over a certain height (commonly 4–6 ft) or when the fence is close to a property line. Check with your local building department before installation. Many areas also require a surveyed property line — placing a fence even a few inches onto a neighbor's property creates legal issues.
