How to Use This Calculator
Measure the total linear feet of fence you need by measuring the perimeter where fence will be installed. For a rectangular yard, measure length and width, then calculate perimeter: 2 × (Length + Width). For example, a 50×75 foot back yard: 2 × (50 + 75) = 250 linear feet. Don't subtract for gates initially—the calculator accounts for gates separately. For irregular perimeters, measure each side and sum the lengths. Accuracy within 12 inches is sufficient—fence materials are sold in whole units (panels, boards, posts) so precise measurement isn't critical.
Select your fence height from common options: 3-4 feet (decorative or front yard), 4-6 feet (standard privacy or back yard), 6-8 feet (full privacy or security). Height affects material costs, labor rates, and building permit requirements. Most residential fencing is 6 feet tall for privacy in back yards, 3-4 feet in front yards for aesthetics without blocking visibility. Check local zoning codes—many restrict front yard fence height to 3-4 feet and require setbacks from property lines. Building permits are required for fences over 6 feet in many jurisdictions.
Choose fence material: wood (cedar, pine, or redwood), vinyl/PVC, aluminum, chain-link, or composite. Material selection dramatically affects costs and longevity. Pressure-treated pine costs least ($10-20 per linear foot installed) but needs staining every 2-3 years. Cedar costs more ($20-30 per linear foot) but resists rot naturally and looks premium. Vinyl fencing ($25-35 per linear foot) never needs painting and lasts 20-30 years. Aluminum ($30-40 per linear foot) provides decorative look with no maintenance. Chain-link ($8-18 per linear foot) is most economical but purely functional.
Enter post spacing and gate width. Standard post spacing is 8 feet on center for wood and vinyl fencing, 10 feet for chain-link. Closer spacing (6 feet) provides more strength in high-wind areas but increases post count and cost. Most fences include one gate—standard gate widths are 3-4 feet for walk-through access. Add double gates (8-12 feet total width) for vehicle or equipment access, costing $300-800 extra. The calculator determines total materials needed: posts, panels or boards, concrete for post holes, gates, and hardware. Results include total cost, estimated installation time, and DIY versus professional pricing comparison.
Understanding Fence Cost Calculations
Fence installation requires three main components: posts (vertical supports every 6-10 feet), rails (horizontal supports connecting posts), and infill (boards, panels, or pickets creating the fence surface). Posts are the foundation—typically 4×4 for wood, metal for chain-link, or vinyl sleeves over metal for vinyl fencing. Posts must be set in concrete (3-foot deep holes minimum, below frost line in cold climates) for stability. Rails connect posts horizontally, usually 2-3 rails per fence section. Infill attaches to rails, creating the visible fence. Understanding this structure helps estimate materials—each 8-foot section needs two posts (shared with adjacent sections), 2-3 rails, and enough boards/panels to fill the section.
Post spacing affects both strength and cost. Standard spacing is 8 feet on center for wood and vinyl, meaning 8 feet from the center of one post to the center of the next. This spacing allows efficient use of materials—8-foot rails and panels fit perfectly. Closer spacing (6 feet) improves wind resistance and reduces sag but increases posts needed by 33%: a 100-foot fence uses 13 posts at 8-foot spacing versus 17 posts at 6-foot spacing. Each post requires concrete (one 50-pound bag minimum) and labor for digging and setting. Extra posts add $150-250 to a 100-foot fence. Chain-link fencing uses 10-foot spacing, reducing post count.
Gate considerations significantly affect total cost and are often underestimated. A standard 3-4 foot walk-through gate costs $100-300 for materials (pre-hung gate kit) plus $100-200 installation. DIY gate building from scratch saves money but requires skill—frames must be square and braced properly to prevent sagging. Double gates for vehicle access (8-12 feet total width) cost $400-800 materials plus $200-400 installation. Gates require heavy-duty posts (4×6 or 6×6 for wood, steel for chain-link) set in deeper concrete (4 feet minimum). Budget 25-40% more for gate posts versus standard fence posts. Self-closing hinges, latch hardware, and locks add $50-150 per gate.
Local building codes and HOA rules heavily regulate fencing. Common restrictions: front yard fence height limits (3-4 feet maximum), setback requirements (fence must be 2-6 inches inside property line, not on it), and permit requirements for fences over 6 feet. Some jurisdictions restrict fence materials or colors. Homeowner Associations often have specific design guidelines—specific colors, styles, or heights. Always check local regulations before starting—building a non-compliant fence requires expensive removal and rebuild. Permits cost $50-200 and require simple site plans. Never assume you can build on the property line—survey your property or hire a surveyor ($300-600) to mark exact boundaries.
Terrain and obstacles affect installation difficulty and costs. Level ground allows straightforward installation—all posts are same length, panels are level. Sloped yards require stepped fence (panels step down in sections) or racked fence (panels follow slope angle). Stepped fencing is easier but leaves gaps under lower panels. Racked fencing looks better but requires custom-cut panels. Slopes add 20-40% to installation time and cost. Trees, rocks, and underground utilities complicate post hole digging. Call 811 for free utility locate service before digging—hitting underground utilities causes expensive damage and service disruption. Rocky soil or ledge rock may require rented equipment (power auger $80-120 per day, jackhammer $60-100 per day) or professional excavation.
Formula & Calculations
Calculate linear feet of fence needed, then convert to posts and sections. For 200 linear feet of fence with 8-foot post spacing: Number of posts = (200 ÷ 8) + 1 = 26 posts. The +1 ensures a post at the beginning and end. Each section between posts needs fence infill (boards, panels, or fabric). Number of sections = number of posts minus 1 = 26 - 1 = 25 sections. If using pre-made 8-foot panels (common for vinyl and some wood fencing), you need 25 panels. If using individual boards (6-inch wide fence boards), calculate boards per section: 8 feet = 96 inches ÷ 6-inch boards = 16 boards per section × 25 sections = 400 boards.
Calculate post hole concrete: each post requires one 50-pound bag minimum, more for larger posts or deeper holes. For our 26 posts: 26 bags at $6 each = $156 for concrete. In cold climates with 42-inch deep holes and 6×6 gate posts, some holes need 2 bags: 24 fence posts × 1 bag + 2 gate posts × 2 bags = 28 bags. Add 10% for spillage/mistakes: 28 × 1.10 = 30.8, round to 31 bags = $186 for concrete. For areas with rocky soil, crushed stone may be easier than concrete: use 2-3 bags of gravel per post at $4-5 per bag.
Calculate horizontal rails (stringers): most fences use 2-3 rails per section. For 6-foot tall fence: 3 rails. For 3-4 foot fence: 2 rails. Our 200-foot fence with 25 sections × 3 rails = 75 rail pieces. Rails are typically 2×4 lumber in 8-foot lengths (matching panel width). At $6 per 8-foot 2×4: 75 × $6 = $450 for rails. For vinyl fencing, rails come with panel kits. For chain-link, top rail is one continuous piece: 200 linear feet at $3-4 per foot = $600-800 for top rail.
Total material cost calculation for wood privacy fence: Posts (26 × $12 for 4×4×8) = $312. Rails (75 × $6) = $450. Fence boards (400 × $3) = $1,200. Concrete (31 × $6) = $186. Gate ($200) = $200. Hardware/fasteners ($150) = $150. Total materials = $2,498 for 200 linear feet of 6-foot wood privacy fence. Material cost per linear foot = $2,498 ÷ 200 = $12.49 per foot. Add labor if hiring professionals: $8-18 per linear foot installed = $1,600-3,600 for installation. Total project cost: $4,100-6,100, or $20.50-30.50 per linear foot installed.
Key Factors to Consider
Material choice affects initial cost, maintenance, and lifespan dramatically. Pressure-treated pine costs least ($10-20 per linear foot installed) but requires staining every 2-3 years ($2-4 per linear foot) and lasts 10-20 years with maintenance. Cedar costs more initially ($20-30 per foot) but resists rot naturally, weathers to attractive gray, and lasts 15-25 years with minimal maintenance. Vinyl costs $25-35 per foot installed, never needs painting/staining, and lasts 20-30 years—best total cost of ownership despite higher initial price. Aluminum ($30-40 per foot) provides decorative look, never rusts, lasts 30-50 years but doesn't provide privacy. Chain-link ($8-18 per foot) is purely functional, lasts 20-40 years with galvanized coating, minimal maintenance but no privacy or aesthetics.
Frost depth requirements affect post setting costs and labor. Frost-free climates allow 2-2.5 foot deep post holes, easily dug with manual post hole digger in 20-30 minutes each. Cold climates require posts below frost line (typically 42-48 inches deep, 60+ inches in extreme cold areas) to prevent frost heaving. Deep holes take 40-60 minutes each to dig manually or require power auger rental ($80-120 per day). A 26-post fence: 26 × 45 minutes = 19.5 hours of digging manually. Power auger reduces this to 5-7 hours but adds rental cost. Cold climates also require more concrete per hole: two 50-pound bags versus one in shallow holes.
Property line accuracy is critical and often problematic. Fences built over the property line onto neighbors' land require removal at your expense ($2,000-5,000+). Most jurisdictions require fences 2-6 inches inside the property line, not directly on it, because property markers (pins, stakes) have ±6 inch accuracy. If property boundaries are unclear, hire a surveyor ($300-800) to mark corners and lines—cheap insurance against neighbor disputes and fence removal. Corner stakes placed 30+ years ago may be missing or inaccurate. Never trust old fences as property line indicators—they're often misaligned. Good neighbor etiquette: discuss fence plans with adjacent neighbors before starting, even if you're within property rights. Offer to finish the fence on their side for appearance (costs $1-2 per linear foot extra but prevents disputes).
Zoning and permit requirements vary widely and carry significant penalties for violations. Common regulations: front yard fence height limits (3-4 feet max), side/back yard limits (6-8 feet max), setback requirements (fence must be 2-6 inches inside property line), and material restrictions (some HOAs prohibit chain-link). Building permits required for fences over 6 feet in many jurisdictions ($50-200 permit cost). Some areas require permits for any fence regardless of height. Swimming pool areas mandate specific fence height (usually 4-5 feet minimum) with self-closing, self-latching gates for safety. Violating code requires expensive fence removal or modification ($2,000-8,000). Always check with local building department and HOA (if applicable) before starting.
Ground conditions affect installation difficulty and cost significantly. Sandy or loamy soil allows easy post hole digging—manual post hole digger sufficient. Clay soil is difficult manually—power auger recommended. Rocky soil or ledge rock may be impossible to dig, requiring professional drilling ($50-150 per hole), specialized equipment, or alternative mounting (surface-mounted posts in concrete). Tree roots in planting path require rerouting fence or removing roots/trees. Slopes require stepped or racked fence design (20-40% cost premium). Wet areas or high water tables may prevent proper concrete setting—gravel or ground spikes may be necessary. Underground utilities (buried before digging—call 811) may require rerouting fence path. Always test-dig one hole before committing to fence path to verify soil conditions.
Frequently Asked Questions
1How much does it cost to fence a backyard?
Fencing a backyard costs $1,500-$10,000 depending on perimeter length, material, and height. Average suburban backyard (50×75 feet, 250 linear feet of fence): chain-link $2,000-4,500 ($8-18 per linear foot), pressure-treated wood $2,500-5,000 ($10-20 per foot), cedar $5,000-7,500 ($20-30 per foot), vinyl $6,250-8,750 ($25-35 per foot), aluminum $7,500-10,000 ($30-40 per foot). These prices include materials and professional installation. DIY reduces costs by $2,000-4,000 but requires 40-80 hours of labor for typical yard. Add $300-1,000 for gates. Complex yards with slopes, obstacles, or difficult access add 20-40%. Always get 3+ quotes—fence pricing varies 25-40% between contractors for identical work.
2How far apart should fence posts be?
Standard fence post spacing is 8 feet on center (from center of one post to center of next) for wood and vinyl privacy fences. This spacing efficiently uses 8-foot rails and panels while providing adequate strength. Chain-link fences use 10-foot spacing. In high-wind areas or for very tall fences (7-8 feet), reduce spacing to 6 feet for added stability. Closer spacing increases post count and cost: 100-foot fence needs 13 posts at 8-foot spacing versus 17 posts at 6-foot spacing. Gate posts require closer spacing: no more than 4 feet for walk-through gates, or use double-width posts (6×6). Corner posts need no additional spacing but should use larger posts (6×6) or braced 4×4s for strength.
3How deep should fence posts be?
Fence posts must be set below frost line depth to prevent frost heaving. Frost-free climates (southern US): 24-30 inches deep for standard 6-foot fence (1/3 of above-ground height underground is the rule). Moderate cold climates: 36-42 inches deep (local frost depth). Extreme cold climates: 48-60 inches deep. For tall fences (7-8 feet), dig proportionally deeper: 36-48 inches even in frost-free zones. Gate posts require deeper holes: add 6-12 inches to standard depth. Post hole diameter should be 3× post width: 12-inch diameter hole for 4×4 post. Proper depth prevents frost heaving (ground freezing pushes posts up 1-3 inches seasonally), which causes fence leaning, broken rails, and gate misalignment.
4Can I install a fence on the property line?
Building directly on the property line is generally not recommended, even where legally allowed. Most jurisdictions require fences 2-6 inches inside your property line (on your side) to account for survey marker tolerance (±6 inches). Building on the line risks encroachment on neighbor's property, requiring fence removal at your expense. Legally, property line fences are shared ownership in many states—both owners have rights and responsibilities, complicating future modifications or removal. Best practice: survey your property ($300-800), mark the line, then build 2-6 inches inside your side. This ensures compliance, avoids neighbor disputes, and gives you full fence ownership. If unsure of property boundaries, never assume—fence removal costs $2,000-8,000 if found to be over the line.
5Do I need a permit to build a fence?
Fence permit requirements vary by jurisdiction. Many areas require permits for: fences over 6 feet tall, fences in front yards, fences near property lines, or any fence in HOA-controlled neighborhoods. Permits typically cost $50-200 and require simple site plan showing fence location, height, and setback from property lines. Some jurisdictions allow permit-free fences under 6 feet in rear/side yards with proper setbacks. Pool fences always require permits due to safety codes. Never assume permit is unnecessary—check with local building department before starting. Building without required permit risks fines ($250-2,500), forced fence removal, inability to sell home (shows on title search), and denied insurance claims for fence damage. HOA approval (separate from building permit) may be required, adding 2-6 weeks for architectural review.
6How long does it take to install a fence?
Professional fence installation takes 1-3 days for typical residential yard (200-250 linear feet). Day 1: mark fence line, dig post holes, set posts in concrete. Day 2-3 (after concrete cures 24 hours): install rails and fence boards or panels. Complex jobs with slopes, gates, or obstacles take 4-5 days. DIY fence installation takes 4-8 full days (2-4 weekends) for 200 linear feet: 1-2 days digging and setting posts, 1 day cure time, 2-3 days installing rails and boards, 1 day gates and finishing. First-time DIY installers should budget 50-100 hours total. Power auger rental reduces digging time by 60-70%. Weather delays extend timeline—can't pour concrete in freezing temps or heavy rain. Schedule fence work for dry, moderate weather. Allow 2-4 weeks total calendar time for permits, material delivery, and work completion.
7What is the cheapest fence option?
Chain-link fencing is cheapest at $8-18 per linear foot installed, or $1,600-3,600 for typical 200-foot backyard. Materials-only (DIY) costs $3-8 per linear foot. Chain-link provides security and pet containment but no privacy or aesthetic appeal. For privacy, pressure-treated pine wood fence is cheapest at $10-20 per linear foot installed ($2,000-4,000 for 200 feet), or $5-10 per foot DIY materials. PT wood requires annual maintenance (staining/sealing) adding $2-4 per linear foot every 2-3 years. For permanent low-maintenance fence, vinyl costs more initially ($25-35 per foot) but eliminates ongoing maintenance and lasts 20-30 years, making it better long-term value despite higher up-front cost. Calculate total cost of ownership over 20 years: wood $6,000 initial + $2,000 maintenance = $8,000 versus vinyl $7,000 initial + $0 maintenance = $7,000.
