Q1. How many fence posts do I need?
To find how many fence posts you need, divide the total fence length by your post spacing (commonly 8 feet on center) and add one for the final post. For example, an 80 foot fence with posts every 8 feet needs 10 sections plus 1, so 11 posts. Add extra posts for each corner, gate, and end. Closer spacing (6 feet) gives a sturdier fence but costs more. Our Fence Calculator estimates posts, rails, and pickets from your total length.
Q2. How far apart should fence posts be?
Space fence posts 6 to 8 feet apart on center for most wood and vinyl fences—8 feet is the most common for standard panels, while 6 feet adds strength in windy areas or for heavier privacy fences. Chain-link can span up to 10 feet between posts. Pre-made fence panels dictate spacing exactly (usually 6 or 8 feet). Closer spacing means more posts and concrete but a more rigid fence; always set corner and gate posts more deeply and securely.
Q3. How deep should fence post holes be?
Dig fence post holes about one-third the height of the post deep, or at least below your local frost line, whichever is greater. For a typical 6 foot tall fence, that means a hole roughly 2 to 3 feet deep. The hole’s diameter should be about three times the post’s width. Set posts in concrete for stability, especially corner, end, and gate posts. Deeper, wider holes resist frost heave and wind, keeping the fence straight for years.
Q4. What fence material should I choose?
Wood (cedar, pine, redwood) offers a classic look and is easy to customize, but needs staining or sealing to resist weather. Vinyl is low-maintenance, won’t rot, and holds up for years, though it costs more upfront. Chain-link is durable and economical for security and pet containment. Aluminum and ornamental steel give an elegant, rust-resistant look for borders. Composite combines wood fiber and plastic for low upkeep. Choose based on your priorities—privacy, maintenance, appearance, or security—and your climate.
Q5. How many pickets do I need for my fence?
To find how many pickets you need, divide the fence length (in inches) by the picket width plus any gap between pickets. For example, a 600 inch fence run with 5.5 inch pickets butted tight needs about 109 pickets; with a 1/2 inch gap, fewer are needed. Privacy fences butt pickets tight or overlap them, while picket-style fences leave deliberate gaps. Add about 10% for waste. The calculator figures pickets, posts, and rails together from your dimensions.
