About this calculator
Three hundred linear feet is a typical backyard perimeter on a suburban lot or one long property-line run. Fence material counts follow directly from post spacing: at the standard 8-foot spacing you get one post per section plus one to close the run, and each post takes one to two bags of concrete depending on depth and hole diameter. This calculator returns post count, panel or section count, rail count, concrete bags, and total installed cost at your material and labor rates, with gates handled separately since they carry hardware and labor costs a plain section does not.

What each field means
Inputs
- Fence length (linear ft)
- The fence length used in the calculation, measured in linear ft. Starts at 300 linear ft so you have a working example on load. Accepted range: 10–5000 linear ft.
- Post spacing (ft)
- The post spacing used in the calculation, measured in ft. Starts at 8 ft so you have a working example on load. Accepted range: 4–12 ft.
- Price per section / panel ($)
- The price per section / panel used in the calculation, measured in $. Starts at 95 $ so you have a working example on load. Accepted range: 0–600 $.
- Price per post ($)
- The price per post used in the calculation, measured in $. Starts at 28 $ so you have a working example on load. Accepted range: 0–200 $.
- Concrete bags per post
- The concrete bags per post used in the calculation. Starts at 2 so you have a working example on load. Accepted range: 0–6.
- Price per concrete bag ($)
- The price per concrete bag used in the calculation, measured in $. Starts at 7 $ so you have a working example on load. Accepted range: 0–25 $.
- Install labor ($/linear ft)
- The install labor used in the calculation, measured in $/linear ft. Starts at 18 $/linear ft so you have a working example on load. Accepted range: 0–80 $/linear ft.
- Gates
- The gates used in the calculation. Starts at 1 so you have a working example on load. Accepted range: 0–10.
- Cost per gate installed ($)
- The cost per gate installed used in the calculation, measured in $. Starts at 400 $ so you have a working example on load. Accepted range: 0–3000 $.

FAQ
How many posts for 300 feet of fence?
At 8-foot spacing you need 38 line and end posts plus two posts per gate, so 40 for a single-gate run. Tighter 6-foot spacing pushes that to 51.
How deep should fence posts go?
One third of the above-ground height, or below the frost line if that is deeper. A 6-foot privacy fence usually means 2 to 2.5 foot holes at 10-12 inch diameter.
Does 300 feet need a permit?
Many municipalities require a fence permit regardless of length, and most enforce height limits and setbacks. A survey is worth the money before setting posts on a run this long.
Accuracy and limitations
- Estimates assume standard, average conditions — local rules, pricing, and materials vary.
- Results are rounded for readability; add a buffer before ordering, booking, or committing.
- Double-check anything with a real cost attached against a local quote.
