Vinyl (PVC) fencing has become the leading low-maintenance residential perimeter solution — no painting, no rot, and a 20-year color warranty from major manufacturers. The pre-assembled panel system makes vinyl one of the fastest fences to install once posts are set.

This calculator counts panels, posts, and caps using the standard 6 ft or 8 ft modular sizes. Vinyl panels lock into routed posts — spacing is fixed by the panel width and is not adjustable.

How to Estimate a Vinyl Fence

Pre-assembled 6 ft or 8 ft panels lock into routed posts · post caps top each post.

Panel count = ⌈Fence Length ÷ Panel Width⌉. Post count = Panel Count + 1 + (2 × gate count). Cap count = Post count.

Vinyl Panel Sizing Reference

  • Privacy panels: 6 ft tall × 6 ft or 8 ft wide, solid tongue-and-groove construction.
  • Semi-privacy: 6 ft tall × 8 ft wide with picket spacing — reduces material cost ~15% vs. solid panel.
  • Picket / open-style: 4 ft or 5 ft tall × 6 or 8 ft wide, used for front-yard and decorative installations.
  • Posts: typically 5″ × 5″ × 7 ft (for 6 ft fence) or 5″ × 5″ × 9 ft (for 8 ft fence), set 30″ in concrete.

Frequently Asked Questions

01

How many vinyl fence panels do I need for 100 feet?

Vinyl fence panels are typically 6 ft or 8 ft wide. For 100 ft of fence: 100 ÷ 6 = 16.7, round up to 17 panels (6 ft) or 100 ÷ 8 = 13 panels (8 ft). Order one extra panel as a spare.

02

How are vinyl fence posts spaced?

Spacing matches the panel width — typically 6 ft or 8 ft on-center. Vinyl panels lock into routed slots in the posts, so spacing is fixed, not adjustable like wood fences.

03

How much does vinyl fence cost per linear foot?

Materials run $25–$40 per linear foot for residential 6 ft privacy vinyl in 2025, including panels, posts, and caps. Add $15–$30 per linear foot for professional installation.

04

Do vinyl fence posts need concrete?

Yes — vinyl posts are hollow and lightweight. Set them in concrete in holes 24–36 inches deep (or below local frost line). Add a small piece of rebar inside the post for extra stiffness in high-wind areas.

05

Will vinyl fence panels fade or yellow?

Quality vinyl fences contain UV inhibitors and titanium dioxide stabilizers — they hold their color for 20+ years. Budget vinyl can yellow within 5 years. Look for a 20-year limited warranty as a quality marker.
