How much fence do I need?
Start with length. Walk your planned fence line, measure each straight run and add them; note every corner, end and gate. Our guide on how to measure a fence line shows the steps. If you are fencing a field, the acreage fence calculator converts acres into perimeter footage. Then pick spacing and style, and the fence calculator does the rest.

Why we don't print prices
Lumber, vinyl and steel prices change month to month and differ by region. Instead of showing a national average that may be wrong for you, our cost calculator multiplies the quantities you need by prices you get from your own supplier or installer. Read fence cost per foot and fence cost in Canada to understand what drives cost.
A five-step fence plan
- Check rules: property line, permits and height limits. See permits and property lines and privacy fence height.
- Measure: total length, corners, gates, slopes.
- Choose material and style: vinyl vs wood, chain link vs wood, board-on-board.
- Calculate: quantities, depth and cost.
- Decide who builds: DIY vs hire, then request locates before digging.
Worked example
Figures below are illustrative examples (2026-10-29), not quotes or guarantees.
Assumptions: a 150 ft, 6 ft wood privacy fence with 8 ft spacing, two extra corner posts, one gate, three rails, 5.5 in pickets with 0.5 in gaps and 10% waste. The fence calculator returns 19 sections, 23 posts, 63 rails, 330 pickets and 46 bags of concrete at two per post. Priced at a hypothetical $20/ft for materials with DIY labour and a $300 gate, the cost calculator shows $3,300 total, $22/ft. Swap in your own prices.
Built for planning, not for code
Our tools are geometry and arithmetic. They do not know your soil, wind, frost depth, bylaws or utility lines. Post depth, permits and property lines are set by your municipality and survey, not by us. For tall fences, pool barriers, retaining walls or anything structural, consult a qualified professional.

Who we are
FenceSizer is a small independent site from Charland & Co. We are not a fence company or a store, and we don't sell your data. See about and disclosure.
How to plan a fence in five steps
- Check the rules. Look up your municipality's height and setback limits and whether a permit is needed. Read our permits and property lines guide.
- Find the line. Locate survey markers or order a survey if the boundary is unclear.
- Measure. Walk and measure every segment, corner and gate with our measuring guide.
- Estimate. Run your numbers through the fence calculator, post calculator, picket calculator and concrete calculator.
- Locate utilities. Request free utility locates through your provincial or state one-call service at least a few business days before digging.
Why we built this site
Fence projects involve lots of small numbers that add up: posts, rails, pickets, bags of concrete, gallons of stain and the cost per foot. Mistakes cost an extra trip to the store or a section that does not fit. These calculators turn your measurements and your local prices into a clear list so you can plan, compare quotes and talk with installers confidently. We do not sell fences or materials, and our numbers are estimates, not quotes.
Choosing a material
Wood is the most common backyard privacy option and is easy to stain or repair. Vinyl costs more upfront but needs little upkeep. Chain link is economical and durable for pets and boundaries. Aluminum and ornamental metal suit front yards and pools where rules allow. Farm wire covers big acreages cheaply. Compare them side by side on our compare page, or dig into vinyl vs wood and chain link vs wood.
Before you dig
Underground lines can be shallow. Always request locates and wait for marks before digging any post hole, even with a hand digger. Keep marks visible until you finish, and hand-dig near them. If your project involves a pool, a retaining wall, or a fence on a steep grade, speak to the municipality and a qualified professional.
Who these tools are for
Homeowners planning a first fence, people replacing an old one, and anyone comparing installer quotes. Start with the fence calculator, then read the FAQ if you get stuck.
Estimates, not quotes
Every result is an estimate from your inputs. Confirm prices, rules and site conditions locally before buying.
Whichever material you choose, plan once, measure twice and confirm locates before digging.
