How to Use This Calculator
- Enter Your Total Fence Length (feet): Start by entering your total fence length — this is the primary input for the calculation.
- Fill In Additional Details: Complete the remaining fields: fence height, panel width, number of gates, price per panel, price per post. Each value refines the calculation for greater accuracy.
- Click Calculate: Hit the Calculate button to run the numbers. Results appear instantly below.
- Review Your Results: Check your panels needed, posts needed. Use these figures to inform your next decision or compare against alternative scenarios.
How It Works
Vinyl fence planning is straightforward: divide total length by panel width to get panel count, then add one post per panel plus end/corner posts and gate posts.
The basic rule:
- Total panels = fence length ÷ panel width (typically 6 or 8 feet), rounded up
- Posts = panels + 1 (each panel needs a post on each side, with adjacent panels sharing posts) plus 2 extra posts per gate
- Each post needs about 1-2 bags of concrete (50 lb) to set in a post hole 10-12 inches wide and 1/3 the post length deep
Gate openings replace one fence panel with a gate kit. Standard walk gates are 3-4 feet wide, and double drive gates are 10-12 feet wide. Gate posts should be reinforced with extra concrete or internal steel posts for support.
Tips & Considerations
- Double-check your total fence length before calculating — even small input errors can significantly change your results.
- Run the calculator with different values to compare scenarios and find the optimal approach for your situation.
- Pay attention to both panels needed and posts needed — they work together to give you the full picture.

- If you're unsure about your price per post, start with a conservative estimate and adjust from there.
Frequently Asked Questions
How much does vinyl fencing cost per foot?
Vinyl fencing costs $15-$35 per linear foot for materials only, and $25-$55 per linear foot installed. Privacy fence (6' tall) runs $20-$35/ft for materials, while picket fence (4' tall) costs $15-$25/ft. Total project cost for 200 feet of privacy fence is typically $5,000-$10,000 installed.
How deep should vinyl fence posts be set?
Fence posts should be buried 1/3 of their total length. For a 6-foot fence, posts are typically 9 feet long with 3 feet underground. Dig holes 10-12 inches in diameter and set posts in concrete. In cold climates, set posts below the frost line to prevent heaving.
How many bags of concrete per fence post?
Each vinyl fence post needs 1-2 bags of 50 lb quick-set concrete. For standard 4x4 posts in 10-inch holes, one 50 lb bag is sufficient. For larger 5x5 posts or deeper holes, plan for 2 bags. Gate posts and corner posts should use 2 bags for extra stability.
Is vinyl fencing cheaper than wood?
Vinyl has a higher upfront cost ($20-$35/ft) compared to wood ($15-$25/ft), but vinyl requires zero maintenance — no painting, staining, or sealing. Over a 20-year lifespan, vinyl is typically cheaper because wood needs restaining every 2-3 years ($3-$5/ft each time).
How long does vinyl fencing last?
Quality vinyl fencing lasts 20-30 years with minimal maintenance. It will not rot, warp, or attract termites. UV inhibitors prevent significant fading. The main maintenance is occasional cleaning with soap and water. Most manufacturers offer 20-year or lifetime limited warranties.
Can I install vinyl fencing myself?
Yes, vinyl fencing is one of the more DIY-friendly fence types. Panels snap or slide into routed posts, eliminating the need for nails or screws. The hardest part is digging post holes and ensuring they are plumb and properly spaced. Allow 1-2 weekends for 100-200 feet of fencing.
