What Is a Line Post and Where Does It Go?
A line post is the standard upright post spaced evenly along a straight run of fence, and it only has to hold panels on two sides pulling in opposite, balancing directions. Because the tension from each side cancels out, line posts carry the lightest structural load on the fence. Spacing between them is usually set by the panel width the manufacturer builds to, so the posts and panels line up without extra cutting.
On a long straight run, line posts repeat the same job over and over: hold the panel up, keep it plumb, and pass the load down into the ground. That simplicity is also why a homeowner walking a property line can usually spot line posts without help. They are the posts that do not change direction, do not carry a gate, and do not sit at a corner.
Why Do Corner Posts Need Extra Reinforcement?

A corner post sits where a fence line changes direction, so it takes pull from two panels at an angle instead of two panels in a straight line, which puts more sideways stress on the post and the footing around it. That angled pull is why corner posts are often set with a larger footing than a line post gets, even on the same fence run.
Skipping that extra reinforcement is one of the more common shortcuts on amateur installs, and it shows up later as a leaning corner. A corner that leans even slightly pulls the two attached panels out of alignment, which can throw off gate clearance if a gate sits nearby. Big Easy Fence Supply sets corner posts to match the angle and load of the specific layout rather than using a one-size approach across the whole property.
What Makes an End Post Different From a Line Post?
An end post sits at the point where a fence run stops, such as where it meets a wall, a building, or a gate opening, and it only carries panel load from one side instead of two. Because the pull is one-directional, an end post takes a steady sideways tug that a line post never feels, since a line post has panels balancing it from both directions.
End posts show up more often than people expect. Every gate opening creates an end post on each side, every wall tie-in creates one, and every spot where a fence transitions from one material or height to another usually needs one too. A property with several gates or transitions will have more end posts than straight-run fence length would suggest.

How Are Gate Posts Built to Handle the Load?

A gate post carries the full swinging weight of a gate panel plus repeated hinge stress every time the gate opens and closes, which makes it the hardest-working post type on the fence. That combination of static weight and constant motion is why gate posts typically go in with a deeper or wider footing than any other post on the run.
A driveway gate puts more demand on its posts than a walk gate, simply because the panel is larger and heavier. Automated gates add another layer, since a motor pushing or swinging the gate hundreds of times a year puts repeated stress on the same hinge points. A gate post that was undersized for the job tends to show it first as sag, where the far edge of the gate drops and starts dragging or scraping.
Do Aluminum and Wrought Iron Posts Work the Same Way?
Both aluminum and wrought iron fencing use the same four post categories, line, corner, end, and gate, because the structural demands come from the fence layout itself rather than the metal. What differs between the two materials is how the post connects to the panel and how it is finished, not which post goes where.
Aluminum posts on residential lines like the Bennington series are built to bolt or set into pre-formed panel brackets, which keeps installation consistent across a long run. Wrought iron posts are more often welded or pinned to the panel for a rigid, traditional look, which suits historic New Orleans properties where wrought iron is common. Either way, the same corner, end, and gate reinforcement rules apply.
What Happens When the Wrong Post Type Gets Used?
Using a line post where a corner, end, or gate post belongs is one of the fastest ways for a new fence to develop leaning corners, sagging gates, or panels that pull loose from their brackets. The failure rarely shows up on installation day. It shows up months later, after wind, gate use, or ground settling has tested the joint repeatedly.
A fence installed with the right post in the right spot spreads that stress out the way it was designed to. That is the difference a correct layout plan makes before the first post ever goes in the ground.
Getting post placement right at the start keeps an aluminum or wrought iron fence line straight, keeps gates swinging cleanly, and avoids the kind of early repair calls that come from an undersized corner or gate post. Big Easy Fence Supply plans every fence layout around the correct post type for each spot on the property, from a straight backyard run to a driveway gate.

Frequently Asked Questions
What Is the Difference Between a Line Post and a Corner Post?
A line post sits along a straight fence run and holds two panels pulling in balanced, opposite directions. A corner post sits where the fence changes direction and takes angled pull from two panels at once, which is why corner posts usually get a larger footing than line posts on the same New Orleans property.
Do Gate Posts Need a Bigger Footing Than Other Posts?
Yes. A gate post carries the full weight of a swinging gate panel plus repeated hinge stress every time it opens, so it typically needs a deeper or wider footing than a line, corner, or end post on the same fence run to keep the gate from sagging.
Can I Use the Same Post Type Everywhere on My Fence Line?
No. Line, corner, end, and gate posts each carry different loads, and using a line post where a corner or gate post is needed is a common cause of leaning corners and sagging gates on residential and commercial installs alike.
How Many End Posts Will My Property Need?
That depends on the number of gates, wall tie-ins, and material transitions on the property, since each one creates an end post on each side. A property with several gate openings will have more end posts than a simple straight-run fence of the same length.
Are Post Types Different for Aluminum Versus Wrought Iron Fencing?
No. Both materials use the same four structural post categories, line, corner, end, and gate. The difference is in how the post attaches to the panel, with aluminum lines like Bennington using bracket connections and wrought iron more often using welded or pinned joints.
