Question 1

How much fence do I need?

Accepted Answer

Measure the perimeter of the area you want to fence in linear feet (US/CA) or meters (UK/AU). For a rectangular yard, add up all four sides; for irregular shapes, walk the property line and measure each straight section. Include gate openings in the linear footage — gates count toward total length but reduce the number of panels needed. A typical suburban backyard fences the back and two sides, leaving the house as the fourth boundary; that's usually 80-150 linear feet.

Question 2

How do I calculate fence posts?

Accepted Answer

Posts = ceil(linear feet ÷ post spacing) + 1 + (gates × 2) + corners. The +1 accounts for the end post; gates need 2 extra posts each (hinge post + latch post); corners need 1 extra post per direction change. For a 100 ft fence with 8 ft spacing and 1 gate: 100÷8 = 12.5, ceil to 13, +1 end = 14, +2 gate = 16 posts. The calculator above does this math automatically including corner posts when you enter your yard layout.

Question 3

How many fence panels do I need?

Accepted Answer

Panels = ceil((linear feet − gate openings) ÷ panel length). Typical residential panels are 8 ft long. For 100 ft of fence with one 4 ft gate, that's 96 ft of fenced run ÷ 8 ft = 12 panels. Chain link doesn't use rigid panels — it's sold by the linear foot in rolls (typically 50 ft rolls). Vinyl fence panels are sometimes 6 ft long; check the manufacturer spec before ordering. Round up — partial panels can't be ordered.

Question 4

How do I measure a yard for fencing?

Accepted Answer

Walk the property line with a measuring wheel or 100 ft tape and record each straight section's length. For complex yards, sketch a rough plan with each segment labeled (north side, east side, etc.) and measure each separately. Don't measure diagonally across the yard — fences follow the property line. Verify property boundaries with a survey or plat map before installing; setting a fence on a neighbor's land creates costly removal disputes. Most jurisdictions require a fence permit for runs over 50 ft or 6 ft tall.

Question 5

What is the standard fence post spacing?

Accepted Answer

Standard residential post spacing is 8 feet (2.44 m) center-to-center — works for wood, vinyl and chain link in average wind and load conditions. Use 6 ft spacing for tall privacy fences (8 ft tall), heavy-duty windy sites, or weak soils. Use 10 ft spacing for ranch and farm fencing where loads are minimal. Pool fences typically require 6 ft spacing to meet building code stiffness requirements. Match post spacing to panel length: 8 ft posts with 8 ft panels means no panel cutting needed.

Question 6

How much does fence installation cost?

Accepted Answer

Installation cost varies by material and region. United States: $10-30 per linear foot installed (chain link cheapest, wood mid-range, vinyl and aluminum premium). United Kingdom: £20-50 per metre installed (wood ~£25, close board ~£40, composite ~£60). Canada: $15-40 CAD per linear foot. Australia: A$70-180 per metre (Colorbond steel ~A$70-100/m, timber ~A$80-150/m). Add-ons: gates ($150-500 each), removal of old fence ($3-8 per linear foot), permit fees ($50-200), HOA approval fees. The calculator's optional pricing fields let you enter your local rates.

Question 7

How accurate are fence calculators?

Accepted Answer

Within 5-8% of professional contractor estimates when you input accurate linear feet, the right post spacing for your material, and the correct gate count. Three sources of error: (1) linear feet — measuring diagonally across irregular yards instead of along the actual property line; (2) post spacing mismatch — using 8 ft default for windy sites that need 6 ft; (3) missing gate posts — forgetting that each gate needs 2 extra posts beyond the regular fence run. Always cross-check with a sketch of the yard before ordering materials.

Question 8

How many linear feet of fence do I need?

Accepted Answer

Linear feet of fence = the total length you walk along the property line you want to fence. For a 60 × 80 ft rectangular backyard fenced on three sides: 60 + 80 + 60 = 200 linear feet. Include gate openings in the total — they count as fence length even though they're not solid panels. For irregular yards, measure each straight section separately and sum. The calculator accepts metric (meters) or US/CA (feet) input.

Question 9

What type of fence is cheapest?

Accepted Answer

Chain link is the cheapest per linear foot: $10-15 installed in the US, including posts and mesh. Pressure-treated wood pickets are next at $15-25/ft installed. Vinyl: $25-40/ft installed (higher upfront but zero maintenance). Aluminum: $30-50/ft (decorative, durable). Composite: $40-60/ft (premium, no maintenance, 30-year warranty). For privacy on a budget: wood pickets are the sweet spot. For maintenance-free: vinyl. For maximum durability: aluminum or composite. Chain link only makes sense without privacy concerns.

Question 10

Does a fence calculator include gates?

Accepted Answer

Yes — the calculator above accepts a gate count input and adjusts the math accordingly. Each gate: (1) reduces the panel count by the gate width (typical 3-4 ft for walk gates, 8-16 ft for driveway gates); (2) adds 2 posts (hinge post + latch post must be sturdier than regular fence posts); (3) adds the gate hardware cost (hinges, latch, lock) which is $50-150 per gate beyond the gate panel itself. Driveway gates typically cost $300-1,000 each in the US.

Question 11

How deep should fence posts be?

Accepted Answer

Post depth must reach below the frost line for stability in cold climates, plus a minimum 1/3 of the post's above-ground height for general support. US South (FL, TX, AZ): 6-18 inches deep. US Midwest (OH, IL): 36 inches. US North (MN, ME): 48 inches. Canada (most provinces): 48 inches (122 cm). United Kingdom: 18 inches (450 mm) per BS 1722. Australia: 600 mm (24 in) minimum for stability per AS 1725 (no frost). For a 6 ft tall fence, even in warm climates use at least 24 in depth — shorter posts can lean over time. Verify local building code requirements before digging.

Question 12

How much concrete do I need per fence post?

Accepted Answer

Standard rule: 2 × 50 lb (22.7 kg) bags of pre-mixed concrete per post for a 4 × 4 in (10 × 10 cm) wood post in a 10 in (25 cm) diameter hole at 36 in (91 cm) depth. Larger posts (6 × 6 in) or deeper footings need 3 bags. Heavy gate posts need 3-4 bags. For 16 fence posts at 2 bags each: 32 bags total. Pre-mixed concrete is cheaper and easier than mixing from scratch; Sakrete or Quikrete in the US, Blue Circle or Hanson in the UK. Always have 10% extra bags for unexpected hole expansion or extra-deep posts.

Question 13

Wood vs vinyl vs chain link fence — which is best?

Accepted Answer

Wood pickets and panels: lowest upfront cost ($15-25/ft installed), classic look, requires staining/painting every 3-5 years, lifespan 15-25 years. Vinyl (PVC): higher upfront ($25-40/ft) but zero maintenance, no painting, 20-30 year lifespan, doesn't dent like aluminum but can crack in extreme cold. Chain link: cheapest ($10-15/ft), security/boundary only (no privacy), galvanized steel lasts 20+ years, black-coated looks better than raw galvanized. Pick wood for budget + classic look, vinyl for low maintenance + curb appeal, chain link for boundary + budget.

Question 14

Can I install a fence myself or should I hire a contractor?

Accepted Answer

DIY fence installation is realistic for short straight runs (under 100 linear feet) on level ground with no significant grade changes. You'll need a post hole digger or rented auger ($60-100/day), 4 ft level, hammer drill (vinyl), and a helper for setting posts plumb. Hire a contractor when: the run is over 200 ft, the yard has significant slope (terraced posts needed), the soil is rocky (mechanical auger required), the local code requires a permit and inspection, or the project includes a driveway gate (motor + hardware is specialist work). Professional install runs $10-30/linear ft and includes permits, materials sourcing and disposal.

Question 15

Do I need a permit to build a fence?

Accepted Answer

Depends on jurisdiction, height and location. United States: most municipalities require a permit for fences over 6 ft tall or in front yards; check your city/county building department. United Kingdom: planning permission required for fences over 2 m (6 ft 7 in) tall or any height in front of a public-facing wall. Canada: varies by province and city; Toronto requires a permit for over 2 m. Australia: state-by-state, NSW requires a permit for over 1.8 m. HOA rules can be stricter than local code. Always check before installing — illegal fences must be removed at owner cost.

Question 16

How much does a fence add to property value?

Accepted Answer

A well-installed fence typically adds 50-70% of its cost to home resale value in the US — meaning a $3,000 fence might add $1,500-$2,100 to home value. Privacy fences in family neighborhoods, pool fences, and dog-friendly fences add the most value. Chain link adds less than wood or vinyl. Curb appeal matters: visible front fences should match the home style. UK: similar pattern (50-60% recoup). Damaged or poorly installed fences can actually reduce value — proper installation and matching the neighborhood aesthetic is critical for ROI.

Question 17

What is fence frost line depth?

Accepted Answer

Frost line is the maximum depth that ground freezes in winter. Posts must be set BELOW the frost line so they don't heave (lift) when the ground freezes and expands. US frost line by region: Florida 0 in; Texas 6 in; Georgia 8 in; Tennessee 12 in; Ohio 32 in; Illinois 40 in; Minnesota 60 in; Maine 60 in. Canada: Toronto 48 in; Vancouver 18 in; Calgary 84 in (!). UK: 450 mm (18 in) typical. Australia: no frost line (mild climates) but minimum 600 mm depth for stability per AS 1725. Always verify with local building department — your county may publish exact frost depth for permit applications.

Question 18

How long does a fence last?

Accepted Answer

Lifespan depends on material and maintenance. Pressure-treated wood pickets: 15-20 years; cedar/redwood pickets: 20-30 years; vinyl: 20-30 years (UV stabilizers prevent yellowing); aluminum: 30-50 years; chain link (galvanized): 20-30 years; composite (wood-plastic blend): 25-30 years with manufacturer warranty. Care extends life: stain/paint wood every 3-5 years, power-wash vinyl annually, repaint metal fences every 5-7 years, replace damaged sections immediately. Hot/humid climates (FL, GA, QLD) accelerate wood rot; cold/dry climates (UT, AB) preserve materials longer.
