How to measure fencing from a site plan
Quick answer
Fencing is a linear measurement plus a count: trace the fence line for total length (m), work out posts from the panel/post spacing, and count gates separately. Set the site-plan scale first, then trace each run. You can do it free in the browser.
Fencing takeoff is quick once the site plan is scaled: it's mostly the length of the fence line, converted into panels and posts, with gates counted on top.
The things to watch are the site-plan scale (often 1:200 or 1:500, not 1:100), corners and level changes, and remembering a post at every end, corner and gate.
Step by step
- 1
Set the site-plan scale
Site and landscape plans are often at 1:200, 1:250 or 1:500. Use the right preset, or draw over a known dimension (a plot boundary or building face) to calibrate.
- 2
Create a fence-line condition
Make a linear condition per fence type (e.g. "1.8 m close-board", "Palisade") so different specs total separately.
- 3
Trace each run
With the linear tool, click along the fence line, following corners and returns, and finish each run. The total length builds live.
- 4
Work out panels and posts
Panels = length ÷ panel width (e.g. 1.83 m). Posts = panels + 1 per straight run, plus an extra post at every corner, end and gate.
- 5
Count gates and add extras
Count gates (pedestrian and vehicle) as their own condition, and note gate posts (usually heavier) separately. Add concrete for post-setting if you're pricing groundworks.
- 6
Export
Export a CSV of the fence lengths and gate counts for your estimate, plus an annotated PDF of the runs you measured.
Tips & gotchas
- •Site plans are usually 1:200–1:500 — set the correct scale or you'll be badly out.
- •Posts = panels + 1 per run, plus one at every corner, end and gate.
- •Keep each fence type/height in its own condition.
- •Count gates separately — they carry heavier posts and ironmongery.
- •Don't forget slope: a run on a slope is longer than its plan length if the gradient is steep.
Frequently asked questions
How do I measure a fence run from a plan?
Set the site-plan scale, then trace the fence line with the linear tool to get the total length. Convert to panels (length ÷ panel width) and posts (panels + 1, plus corners/ends/gates). Solid Takeoff totals the length live.
How many posts do I need?
Roughly one more than the number of panels on each straight run, plus an extra post at every corner, end and gate opening.
What scale are site plans?
Commonly 1:200, 1:250 or 1:500 — larger than building plans. Always set the correct scale (or calibrate from a known boundary) before measuring.
Is it free?
Yes — linear measurement, counts and export are on Solid Takeoff's free plan.
