Privacy Screen Calculator
Size privacy screen panels, posts, framing, and installed cost. Six style families (square / diagonal lattice, horizontal slat, vertical slat, louvered, decorative laser-cut) × five materials (PT pine, cedar, composite, aluminum, vinyl). Privacy effectiveness scoring (45-92%), deck-mounted or freestanding (with concrete footing math), 25-year total cost of ownership including maintenance cycles.

How to use
How to use the privacy screen calculator in 5 steps.
- 1
Enter screen dimensions
Total run in linear feet + height in feet. Common heights: 5 ft (privacy from sitting), 6 ft (full standing privacy), 7-8 ft (above eye-line). Heights over 6 ft typically require a permit.
- 2
Pick a style
Square or diagonal lattice (partial privacy + budget), horizontal slat (modern, ~80% privacy), vertical slat (traditional, ~85% privacy), louvered (premium, ~92% privacy + ventilation), decorative laser-cut (designer aesthetic, ~70% privacy).
- 3
Pick a material
PT pine (cheapest, re-stain every 2-3 yrs), cedar (premium aesthetic, 25-yr life), composite (no-maintenance, $0.25/lf/yr), aluminum (modern + lifetime, $0.15/lf/yr), vinyl (white traditional, $0.30/lf/yr).
- 4
Pick mount type
Deck-mounted attaches to existing deck posts using brackets — no new footings. Freestanding requires new 4×4 PT posts in concrete footings (2 bags of 60lb Quikrete per post) and adds about $30/post in materials.
- 5
Read your BoM + cost
Panel count + post count + brackets + concrete (if freestanding) + labor breakdown. 25-yr TCO includes maintenance cycles per material. Save link, export PDF, embed.
How we calculate
How DeckMath calculates this — IRC 2021 sources.
The Privacy Screen Calculator sizes the panels, posts, framing, and installed cost for a deck-mounted or freestanding privacy screen. Six style families (square lattice, diagonal lattice, horizontal slat, vertical slat, louvered, decorative laser-cut) × five materials (PT pine, cedar, composite, aluminum, vinyl) covers most residential designs. Enter the total length, height, style + material, and the calculator returns panel count, post count, full bill of materials (panels + posts + brackets + hardware + concrete for freestanding), installed labor, and 25-year total cost of ownership including maintenance.

Material prices reflect 2026-Q1 retail national-median (Home Depot / Lowe's / specialty fence + panel suppliers). Labor uses RSMeans 2026-Q1 residential index. Style privacy factors derived from manufacturer specs + independent visibility testing. Permit threshold per local zoning common practice (6 ft cap).
Most prefab panels are 4 ft wide — 24 ft of screen = 6 panels. The calculator rounds up so you always have enough panel area.
Each panel needs a post on each end, with adjacent panels sharing the middle posts. 6 panels = 7 posts (including start + end).
The visible face of the screen — drives material cost via $/sqft pricing for each style.
Style sets the base $/sqft (horizontal slat $5.20, louvered $7.50, etc). Material multiplier scales for cedar (×1.45), composite (×2.20), aluminum (×2.80) vs PT baseline.
Baseline $8.50/sqft for installed horizontal slat. Style multipliers: lattice 0.95×, slat 1.00×, louvered 1.30× (angled cuts), decorative 1.20×.

Privacy screen questions, answered.
Pressure-treated pine at $5.20/sqft (horizontal slat style) is the most affordable upfront. Total installed cost for a 24 ft × 6 ft screen in PT slat: roughly $1500-1800. Cedar costs ~45% more but lasts 30-40% longer and looks better. For pure budget, lattice (square or diagonal) in PT is even cheaper at $4.50/sqft material — total around $1200-1400 installed.
Most jurisdictions cap residential fences + privacy screens at 6 feet without a permit. Above 6 ft typically requires a permit + setback compliance check (often 5-10 ft from property line). Some jurisdictions allow 8 ft in backyards with a permit; front-yard screens are often capped at 4 ft regardless. Always verify with your local zoning office before going over 6 ft.
Depends on mount type. Deck-mounted screens attach to existing deck framing or posts — no concrete needed. Freestanding screens need 4×4 PT posts set 2-3 ft deep in concrete footings (2 bags of 60lb Quikrete per post). The calculator adds the concrete cost automatically when you select "freestanding". For decks above 30″ off grade, deck-mounted is usually easier and code-compliant.
Louvered (angled boards) at 92% privacy effectiveness — boards angled so you can't see through from anywhere except directly overhead. Vertical slat (1×4 boards with 1/4″ gaps) is close behind at 85%. Horizontal slat is 80%. Lattice is only 45-50% — pick lattice for partial screening + plant trellis. For maximum privacy + ventilation, louvered is the answer.
PT pine 18 yrs, cedar 25 yrs, vinyl 28 yrs, composite 30 yrs, aluminum 35 yrs. Aluminum is the longest-lasting and lowest-maintenance — most aluminum screens carry lifetime structural warranties. Cedar has the best aesthetic but requires re-staining every 2-3 years to maintain color. Composite is the sweet spot for low-maintenance with a natural look.
A standard 24 ft × 6 ft (144 sqft) horizontal slat screen in PT pine runs $1500-1800 installed in most US markets. Cedar same size: $2100-2500. Composite: $3100-3700. Aluminum: $3800-4500. Louvered styles add 30% labor premium. Multiply by ~0.92× for South, 1.28× for West Coast. Calculator returns regional cost.
Yes for most styles. Prefab panels make DIY feasible — typical 24-ft horizontal slat install takes a weekend for a moderately experienced DIYer. Louvered panels are harder (precise angled cuts required); decorative laser-cut panels are easiest (just hang the panels). Freestanding requires concrete work which adds ~1 day. Materials savings vs pro install: typically 35-45% of total.
Initial installed cost + 25 years × annual maintenance cost (per linear foot). PT pine has the highest maintenance ($1.20/lf/yr for re-staining), aluminum the lowest ($0.15/lf/yr for occasional cleaning). For a 24-ft screen, 25-yr maintenance ranges from $90 (aluminum) to $720 (PT). Even with higher upfront cost, aluminum/composite often win on 25-yr TCO.
Yes — louvered installs are 30% more labor-intensive than horizontal slat because the angled boards require precise miter cuts. Decorative laser-cut panels are 20% more (alignment + hardware). Lattice is 5% LESS labor (panels are pre-assembled). The calculator applies the style multiplier automatically.
Aluminum or composite horizontal/vertical slats. The calculator flags this combo with a "low-maintenance match" advisory. Aluminum is the absolute lowest maintenance (occasional cleaning only) — perfect for owners who want maximum aesthetic with zero ongoing work. Composite is close behind and offers a wider color palette.
