# Wood Fence Estimates Calculator

Wood fence estimates calculator for pressure-treated and cedar. Get posts, rails, pickets, concrete, and total cost including DIY vs pro labor for any length.

## What this calculates

A wood fence costs $15-45 per linear foot installed in 2025, but that range is huge because of wood type, height, style, and whether you DIY or hire a pro. This wood fence estimates calculator breaks down the numbers line by line: how many posts, rails, pickets, and concrete bags you need, and what they cost for pressure-treated, cedar, or redwood. DIY mode shows materials only; pro mode adds labor at the national average of $18 per linear foot.

## Inputs

- **Fence Length** (ft) — min 0 — Total linear feet of fence (include gates)
- **Fence Height** (ft) — min 3, max 8 — Standard wood fence is 6 ft; 4 ft for front yards, 8 ft for maximum privacy
- **Wood Type** — options: Pressure-treated pine (budget), Western red cedar (premium), Redwood (California / Pacific NW) — Affects all lumber costs
- **Fence Style** — options: Privacy (no gaps between pickets), Semi-private (1-2 in gap), Picket (3 in gap), Shadowbox / board-on-board
- **Post Spacing** (ft) — min 4, max 10 — 6 ft is sturdier; 8 ft saves posts and is acceptable for standard wood fence
- **Gates** — min 0, max 5 — Typical residential: 1 walk gate. Add drive gate if relevant.
- **Labor** — options: DIY (materials only), Pro installation ($18/linear ft labor)

## Outputs

## Details

## What a Wood Fence Costs in 2025

| Wood Type | DIY ($/linear ft) | Pro Installed ($/linear ft) |
|---|---|---|
| Pressure-treated pine | $8-14 | $22-32 |
| Western red cedar | $14-22 | $30-45 |
| Redwood | $18-28 | $38-55 |

A typical 150 linear foot backyard privacy fence in pressure-treated pine costs:

- **Materials:** $1,500-2,100 (DIY)
- **Pro installed:** $3,300-4,800

Cedar runs about $2,100-3,300 DIY, $4,500-6,800 pro. Redwood is premium and usually only used where the local climate supports it (Pacific Northwest, coastal California).

## Materials Breakdown for 150 ft of 6 ft Privacy Fence

Assuming 8 ft post spacing, privacy style (no gaps between pickets):

- **Posts:** 19 line posts (150 / 8 + 1) plus 2 gate posts = 21 posts
- **Rails:** 19 sections x 3 rails (6 ft fence takes 3 rails) = 57 rails
- **Pickets:** 150 ft = 1,800 inches / 5.5 inch pickets = 327 pickets
- **Concrete:** 21 posts x 2 bags = 42 bags of 80 lb
- **Gate:** 1 walk gate kit with hardware

## Post Depth and Concrete

Post hole rule: **1/3 of post length buried**, minimum 2 feet. For a 6 ft fence, use 8 ft posts with 2 ft buried; for an 8 ft fence, use 10 ft posts with 3 ft buried. Each post hole uses 2 bags (6 ft fence) or 3 bags (8 ft fence) of 80 lb concrete, assuming a 10-12 inch hole diameter.

## Pressure-Treated vs Cedar vs Redwood

- **Pressure-treated pine:** cheapest, 15-20 year lifespan, looks industrial when new, silvers over time, can twist and crack. Use for utilitarian fencing.
- **Western red cedar:** 20-30 year lifespan, natural rot and insect resistance, looks premium, stable dimensions. The default for quality residential wood fencing.
- **Redwood:** longest lifespan (30+ years), most expensive, distinctive reddish color, dense. Best in wet coastal climates.

## Why Wood Fence Estimates Vary

Two identical-looking 150 ft fence quotes can differ by $2,000-3,000. Drivers:

1. **Terrain.** A flat backyard vs a steeply sloped one can add 20-40% labor.
2. **Removal of old fence.** $3-8 per linear ft extra if the old one has to come down.
3. **Access.** Narrow gates, tight yards, or second-story jobs add labor.
4. **Permit and survey.** $50-500 depending on jurisdiction.
5. **Staining or sealing.** $1-3 per linear ft extra if done at install.
6. **Gate style.** Walk gate kits are $40-100; arched or decorative gates are $200-500+.

## DIY vs Pro Labor

DIY saves 50-60% of total cost but takes 3-7 days of weekend work for 150 ft. If you own a post-hole digger and have help with setting posts, it is reasonable. If you have rocky soil, steep terrain, or city inspection requirements, hire a pro.

Pro install at $18-22/linear foot covers two-person crew, post setting with concrete, cut-to-fit pickets, gate installation, and haul-away. Per-linear-foot pricing scales down for longer fences (economy of setup) and up for shorter fences (minimum crew day charges).

## Rails and Pickets Reference

- **6 ft fence:** 3 rails per section (top, middle, bottom)
- **4-5 ft fence:** 2 rails per section (top and bottom)
- **Privacy (no gap):** picket count = fence length in inches / 5.5
- **Picket style with 3 in gap:** picket count = fence length in inches / 8.5
- **Shadowbox / board-on-board:** double picket count vs privacy (pickets on alternating sides of the rail)

## Frequently Asked Questions

**Q: How do I use the wood fence estimates calculator?**

A: Enter the total linear feet of your fence, the fence height (4, 5, 6, or 8 ft), select wood type (pressure-treated pine, cedar, or redwood), choose the style (privacy, semi-private, picket, or shadowbox), and pick DIY or pro labor. The wood fence estimates calculator returns the count of posts, rails, pickets, and concrete bags plus the total cost broken into materials and labor. Adjust post spacing from the default 8 ft to 6 ft for a sturdier fence.

**Q: How much does a wood fence cost per linear foot?**

A: DIY pressure-treated pine runs $8-14 per linear foot (materials only) for a 6 ft privacy fence. Cedar is $14-22 DIY. Pro installation adds about $18/linear foot for labor, bringing pressure-treated to $26-32 installed and cedar to $32-45 installed. Redwood is the most expensive at $18-28 DIY and $38-55 installed. A 150 ft backyard pressure-treated fence professionally installed is typically $3,300-4,800.

**Q: How many posts do I need for a 100 ft wood fence?**

A: At 8 ft post spacing, 100 / 8 = 12.5 sections, round up to 13 sections, which needs 14 line posts (sections + 1). Add 2 extra posts per gate. One walk gate = 16 total posts. At 6 ft post spacing for a sturdier fence: 100 / 6 = 16.67, round to 17 sections, 18 line posts, plus 2 gate posts = 20 total.

**Q: Can I use 8 ft post spacing for a 6 ft wood fence?**

A: Yes, 8 ft spacing is standard for 6 ft wood fences in most areas. It is the default for a reason: balance between cost and strength. In high-wind areas or for very tall 8 ft privacy fences, drop to 6 ft spacing (more posts, more concrete, stiffer fence). If your fence runs along a property line with uneven soil, 6 ft spacing also helps keep the top rail straight over long distances.

**Q: How much concrete do I need per fence post?**

A: For a 6 ft fence with 8 ft posts (2 ft buried) and a 10-12 inch diameter post hole, use 2 bags of 80 lb concrete per post. For an 8 ft fence with 10 ft posts (3 ft buried), use 3 bags per post. Fast-setting concrete (Quikrete Fast-Setting) costs about $1 more per bag but does not require premixing and is fine for fence posts. Regular concrete is acceptable if you can wait 24 hours before hanging rails.

**Q: Is cedar worth the extra cost over pressure-treated pine?**

A: For a permanent fence you plan to keep 20+ years, yes. Cedar lasts 20-30 years without staining versus 15-20 years for pressure-treated, stays dimensionally stable (no cupping, twisting, or cracking), and has a premium appearance even when weathered to gray. The extra $5-10 per linear ft installed is typically recouped in longer life and reduced maintenance. For a short-term rental property or utility fence, pressure-treated is the right call.
