Vinyl fences come as ready-made panels, so the count is simple, but the posts and gates are easy to get wrong. This calculator gives you panels, posts, caps, gate kits and concrete, plus the post length to order.
Your shopping list
How to use the Vinyl Fence Calculator
- Enter the length of the fence.
- Pick your panel width. 8 ft panels are the most common, and 6 ft panels are also sold.
- Pick the fence height and how deep your posts will go.
- Add your gates. Read the list and copy it.
The math behind it
Run = length – (gates x gate width)
Panels = run / panel width, rounded up
Posts = panels + 1 + one extra post per gate
Post length = fence height + hole depth
Concrete = 3 bags of 60 lb per 5 in post

- Use the post that comes with your panels. Sizes differ between brands.
- Let the concrete cure before you slide panels in, or they can shift.
Common questions
How many posts for a vinyl fence?
You need one more post than panels, plus one extra for every gate.
How deep should vinyl posts go?
Most go 30 to 36 in deep, and deeper where the ground freezes.
Do I need to cut the panels?
Often only the last one. Measure the gap first, then cut the panel to fit.
Can I use this for gates?
Yes. Enter the gate width and number of gates, and the list adds the extra posts and gate kits.
